What It Feels Like to Regain Your Insulin Sensitivity

The insulin molecule.

Like many men, when I hit my early thirties I started to get a little fat.  At my heaviest I was just a little chunky.  I think that at a certain point I started to become less sensitive to the hormone insulin, which in turn led to a host of other negative health effects.  I’d like to share my experience of reversing this trend.  With changes to my diet and lifestyle, I regained my insulin sensitivity.

The day after Halloween seems like an appropriate day to write this post — for one thing I need to fortify my own willpower so I don’t eat too much of the leftover candy.

How I Cured My Asthma With One Simple Lifestyle Change

After years of suffering from adult-onset asthma, I promised myself that if I ever found a way to cure myself, I would share that information with the world.  In a way, it’s the reason I started this blog.  It’s taken me until now to write this post because it’s a difficult subject to write about.

Vinyl shower curtains — attractive but deadly.

I started to experience asthma symptoms on a daily basis in 2001, at the age of 32.  The symptoms (chest tightness, and the annoying feeling that when you take a deep breath it doesn’t “catch” — like you’re not actually getting the air) started immediately after we replaced our cloth shower curtain with a plastic one.  It took me awhile to make the connection, but the toxic PVC fumes released by the hot steam were causing my breathing problems (or at least aggravating an underlying condition to the point where I experienced symptoms).  It probably didn’t help that our house was also full of mold; the upstairs neighbors had flooded their bathroom, the water had dripped down into our kitchen, and our property manager refused to repair the damage (we were renting at the time).  Moldy ceiling tiles — yuck!

We got rid of the offending shower curtain, but my asthma symptoms persisted.  The degree of severity would fluctuate — sometimes I would feel almost normal, other times my breathing was so bad that it was difficult to sleep.

At times I felt helpless and depressed.  Would I ever breathe normally?  At other times I felt determined — I would figure out a way to improve my health and quality of life.

A Little History

My grandma smoked, and she lived to be 102, blah blah blah …

I grew up in the 70’s, and, like most kids of the 70’s, inhaled my fair share of second-hand smoke.  Now we know that’s a risk factor for asthma.  I forgive my parents and their friends — they knew smoking wasn’t good for them but they had no idea they were hurting the kids.  (The equivalent challenge for my generation, as parents, is to not expose your family to bisphenol-A, which is everywhere).

Once I thought about it, I realized I had experienced asthma symptoms as a teenager, at times.  I had always had a misconception that people with asthma couldn’t take a deep breath; since I could fill my lungs completely, I didn’t think I had asthma.  But the symptoms — chest tightness and that feeling that your lungs aren’t full (even when they are) — were there, even when I was in high school.  But they were intermittent, only lasting a few days at most.

I went to college at UC Davis.  The air in Yolo county is filled with dust and pollen, and I experienced bad hay fever throughout my college years.  No asthma, but lots of sneezing.  It was also during this time, having moved out of my family home, that I realized I was allergic to cats.  I had grown up with cats as pets my entire life.  I had also spent a great deal of time sneezing, and with watery eyes.  Go figure.

What I Tried — SUPPLEMENTS

Starting in 2001 (when I started experiencing asthma symptoms every day) I experimented with a large number of supplements.  Most had no effect on my asthma symptoms.  Some made my symptoms worse.  A few helped to some extent.  Supplements are not the “cure” I’m referring to in the post title, but some are worth mentioning anyway.

Vitamins — some are good, some are evil.

Multivitamins — Multi-vitamin/mineral supplements tended to aggravate my symptoms, and I haven’t been able to figure out why (too many ingredients, and too many brands to do any kind of controlled experiment).  It could have something to do with the complex synergies that exist among different vitamins and minerals — too much of one ingredient might prevent absorption of another ingredient that is helpful to asthma.  Or maybe one of the ingredients in multi-vitamins catalyzes one of the many possible inflammatory chain reactions that are possible in the human body.  I don’t think it’s an allergic reaction to a filler or a coating, as I’ve tried out many high quality and hypoallergenic brands, all with the same adverse effect.  I suspect one or more of the B vitamins is to blame, since high-potency doses of B-complex also have an adverse effect on my breathing.

Vitamin C — There’s a great deal of research that supports the use of Vitamin C as a treatment of asthma, especially against exercise-induced asthma.  My own experience was that vitamin C provided some relief, and did help reduce asthma symptoms.  It wasn’t a cure, but it helped.  For me, positive benefits seemed to top out at about 500mg/day.

Vitamin B6 — Some research has been conducted on the effect of vitamin B6 supplements on asthma, with mixed results.  My own experience was also mixed; sometimes taking B6 seemed to help, other times not.  B6 may help prevent the overproduction of histamine, and may be more effective at controlling allergies than asthma.

Magnesium — Magnesium helps keep smooth muscle fibers (the kind in your lungs) relaxed.  I’ve noticed a beneficial effect on my breathing from taking magnesium.  Magnesium citrate is a better bet than magnesium oxide — too much of the latter can make you run to the bathroom.  If you want to try taking magnesium, start with a 200mg dose (or less, and work your way up to see how much you can tolerate).  There has been a great deal of research concerning magnesium and asthma.

Evening primrose oil — This oil supplies a fatty acid (GLA) which can have a positive anti-inflammatory effect.  It’s a traditional treatment for asthma in some cultures.  Supporting clinical evidence is weak, but I’ve noticed a beneficial effect from a 1000mg dose.

Bromelain — This is an enzyme extracted from pineapple.  It has a strong anti-inflammatory effect that lasts a few hours.  I found that putting half a pill (250mg) under my tongue (to more quickly absorb the enzyme into my bloodstream) would make me breathe easier within half an hour.  At least one mouse study has found bromelain to be effective against asthma.  On the other hand, if I take too much bromelain, it makes my heart race.

Note on bromelain: A few years ago there was an “asthma cure” going around the internet that recommended megadoses of Blue Bonnet Super Quercetin.  I don’t think quercetin does a thing for asthma, but in my experience bromelain is effective, and that particular formulation contains bromelain.

Fish oil — Keeping a favorable dietary Omega-3 to Omega-6 fatty acid ratio is extremely important in managing inflammatory conditions.  I’ll go into more detail later, but I recommend fish oil for pretty much everyone (not just to people with asthma, but also to improve heart health and to prevent depression and seasonal affective disorder).  To avoid fish burps, keep fish oil in the refrigerator, and take it with food.  I generally take about 4g of fish oil and/or cod liver oil (in winter) daily, in capsule form.  Here is a summary of research regarding fish oil and asthma.

Raw garlic — In my experience, eating raw garlic is effective against asthma.  Unfortunately, raw garlic comes with its own side effect — garlic breath and even garlic body odor if you eat too much.  To minimize garlic breath, you can chop up a small clove (or half a large clove) into small pieces, swish those pieces around in a small amount of water, and then swallow the whole thing quickly.

Some supplements I found to be effective against allergies (like black seed, nettle, and MSM), but not helpful in controlling asthma symptoms.

What I Tried — DRUGS

I’ve always been wary of using powerful drugs to treat illness — too many side effects and not enough research.  However I quickly grew desperate enough to get over my drug hang-ups and try them all.  Here’s a brief summary of my experience with using drugs to treat asthma.

The classic asthma accessory.

Albuterol Albuterol is one of the most commonly used asthma drugs, and works by relaxing smooth muscle in the lungs, thus easing bronchospasm (airway constriction).  For me, albuterol provided zero relief, and did nothing to improve my PEF.  This was a strong indication that the underlying cause of my symptoms was primarily airway inflammation (more so than airway constriction).  This made sense to me — I had never ended up in the ER with acute breathing problems (many of my friends with asthma have).  My symptoms were less severe, but more chronic.

Steroids (glucocorticoids) — I tried several brands of steroid inhalers, and found that they provided quick, lasting relief.  I remember distinctly at one point taking a normal breath, feeling it “catch,” and experiencing a powerful combined sense of emotional relief, and outright joy.  I would be able to breathe normally again!

I would have been willing to tolerate some of the side effects of glucocorticoid use (weight gain, reduced immunity, muscle weakness, weakened bones), but there was one side-effect I could not tolerate.  Each time I tried inhaled steroids, I would start experiencing severe mood swings within a few days.  One time I even felt suicidal — the first time I had ever experienced that feeling in my life.  Glucocorticoids lower both plasma and brain serotonin levels, and are linked to depression and feelings of aggression.  My violent mood swings stopped as soon as I stopped using them.  Back to the drawing board.

Leukotriene Inhibitors — Leukotrienes are fatty molecules that play a role in immune function and inflammation.  I found the effect of taking a leukotriene inhibitor to be intensely drying (an anti-histamine effect), but not helpful to my asthma symptoms.  This class of drugs is probably more effective for allergic rhinitis (the other condition it is prescribed for).  A very effective, but cheaper (and probably better for you) alternative that does more or less the same thing is black seed (black cumin).  Black seed is very effective against both seasonal allergies and coughs — according to this site black seed oil contains chemicals which inhibit leukotriene synthesis.

Tianeptinetianeptine (Stablon) is an antidepressant drug that works via increasing serotonin uptake (the opposite action of antidepressents like Prozac, which inhibit serotonin reuptake; SSRI = selective serotonin reuptake inhibitor).  Tianeptine has long been known to decrease asthma symptoms; the drug reduces plasma serotonin (high plasma serotonin can induce bronchoconstriction).

I didn’t try tianeptine until I was fairly desperate.  I ordered some from a mail-order company of dubious legality.  I took some, starting with one pill a day, and found that it worked.  Not as well as steroids — but better than most of the supplements I had tried.

There were a few problems with tianeptine; after a few days of taking it I would notice a drop in energy, and well as wonky moods (ups and downs unrelated to my life circumstances).  It’s a powerful drug.  If you’re severely depressed and asthmatic, I would definitely recommend it over any SSRI (for one thing, tianeptine has no sexual side effects).  But for less severe cases of both conditions, there are safer, simpler modes of treatment (keep reading).

What I Tried — DIETARY RESTRICTIONS

I tried modifying my diet to see if it improved my asthma symptoms.  At various times I tried eliminating dairy products, all caffeine, red meat, wheat, red wine, all alcohol, nuts, and a number of other foods and categories of food.  Some of these food trials seemed to work; I would often go days without symptoms.

I kept trying to find the one food that was causing my symptoms.  I ordered an expensive ELISA blood test to try and discover which “hidden food allergies” I might have (I didn’t have any obvious ones — like going into anaphylactic shock if I ate peanuts).  I was surprised that the test showed I was allergic to … no foods at all.  A mild sensitivity to honey (which I rarely ate), and otherwise nothing.

Still, I felt that modifying my diet was somehow the key to managing my symptoms, and that instinct eventually proved to be correct.

What I Tried — OTHER STUFF

Avoiding environmental allergens — I went to an allergist and was tested for various allergies.  I showed strong sensitivities to a wide range of flower, weed and tree pollens.  I was also found to be highly allergic to dust mites.

I bought dust-mite proof covers for my mattress and pillows.  Those did help — with allergies.  I stopped sneezing every morning.  But it didn’t help with asthma.

I found that when I traveled, my asthma symptoms would often disappear.  The pollens I had grown up and become sensitized to weren’t present in other environments.  But I loved living in the Bay Area.  I didn’t want to move.  Air quality is better in San Francisco than in Oakland (mostly because of SF’s proximity to the ocean, and wind), but I didn’t want to move to San Francisco — too much traffic and not enough sun and open space.

In 2002 we did move out of the mold house — we bought a great house in Oakland.  My symptoms improved somewhat, but still persisted.

Buteyko method — the Buteyko method is a breathing technique that can help relieve asthma symptoms.  It works — but it’s extremely difficult!  The basic idea is to slow your breathing and boost the CO2 levels in your bloodstream.  This has the effect of opening up your airways, decreasing both bronchoconstriction and inflammation.  Eventually, you can train yourself to permanently slow your breathing and control asthma symptoms.

I don’t buy the Buteyko method premise that all asthmatics “chronically overbreathe.”  From my limited experience with scuba diving, I learned that I breathe less, or more slowly, than average, yet I still experienced asthma symptoms.  However the techniques are still useful, and can probably prevent a trip to the ER for someone experiencing an acute asthma attack.

Panacea?

The Water Curethis simple, free method (drink way more water, avoid all caffeine, and include some sea salt in your diet) has no doubt worked for some people.  Some of the premises have been found to be bunk (like the idea that all caffeinated beverages — even very weak green tea — are dehydrating), but I think there’s something to the idea that chronic dehydration is closely linked to bronchoconstriction.  Since my asthma symptoms were more related to airway inflammation, rather than constriction, the water cure didn’t do much for me (except make me piss a lot).

Other Observations

Two interesting observations.

  1. Whenever I had a cold, my asthma symptoms would disappear entirely.  Of course, I would be sneezing, congested, and miserable, but no breathing troubles!  This was a clue that the disease was closely linked with immune function.  Perhaps when my immune system was occupied with a real threat (a cold virus), it would ignore the environmental allergens that would trigger my asthma symptoms.
  2. The same thing was true if I had hay fever.  If I was experiencing allergy symptoms (sneezing, runny nose, watery itchy eyes, etc.) my breathing would be fine.  At the same time I found that drugs or supplements that inhibited histamine would sometimes make my breathing worse.  I realize that many people experience asthma and allergies together.  While I have experienced both conditions, they’ve never occurred at the same time.

I can’t adequately explain either observation, but I wanted to share them nonetheless.

What Worked

I tried most of the above methods between 2001 and 2003.  By 2004, I was reducing my symptoms to some extent with a regular intake of fish oil, evening primrose oil, vitamin C, and magnesium.  Taking fish oil daily was a major turning point — it really helped keep my airway inflammation in check.  I think my Omega-3/Omega-6 fatty acid ratio was severely skewed towards Omega-6 (just as it is in most people in the U.S., including vegetarians and vegans).  The additional Omega-3’s (EPA/DHA) in fish oil helped correct this problem.

I noticed another consistent improvement in my symptoms when I reduced the amount of wheat I was eating.  I sharply reduced the amount of  bread, pasta, pizza, pastries, and even whole-wheat products I was consuming.  My breathing improved, and within a few months I lost about ten pounds of fat and retained water weight.

Solution: eat real food.

In 2006 I began to experiment with going “all the way” with the so-called “paleolithic diet.”  For the most part, I cut out all grains, legumes, cow’s milk, and processed foods.  Instead of having “pile o’ starch” as the basis of every meal, I began to eat animal protein (seafood, poultry, eggs, and meat), fresh fruit, and non-starchy vegetables, with generous amounts of olive oil, butter, and nuts.  I also started to eat grass-fed/pastured meat and butter (much higher in anti-inflammatory Omega-3’s than grain-fed animal products), and to supplement with 5K IU of vitamin D on most days (especially during the winter).

The effects of this dietary experiments were dramatic.  My asthma symptoms virtually disappeared, and I lost an additional ten pounds of fat and retained water.

Why Does It Work?

I think there are at least five reasons why the paleolithic diet is effective against asthma:

  1. The diet improves the Omega-3/Omega-6 ratio, which is effective against inflammatory conditions.
  2. The diet is high in vitamin D.  Vitamin D levels are inversely correlated with asthma symptoms.
  3. The diet is low in lectins, gluten, and casein a1, all of which which are associated with “leaky gut syndrome.”  Whole, undigested proteins (as opposed to amino acids) directly entering your bloodstream via your intestines can trick your immune system into attacking its own tissues (resulting in chronic inflammation).
  4. The diet is relatively low in carbohydrates, which helps keep plasma serotonin levels from getting too high (which can trigger bronchoconstriction).
  5. The diet is very high in phytonutrients, many of which have anti-inflammatory effects.

Asthma is primarily an allergic disease — the immune system reacts with inflammation and airway constriction to factors in the environment (pollen, bacteria, viruses, molds, proteins) that it has become sensitized to.  The paleo diet has the effect of making the immune system less “twitchy” — less prone to autoimmunity and inflammation.

Is It Hard To Eat That Way?

I don’t find it difficult, but I’m not that strict.  I follow Mark Sisson’s “primal” version of the paleolithic diet, which allows dark chocolate, coffee, tea, and some wine and beer.  I also eat some dairy products, but I try to stick to the “a2” casein varieties of dairy (milk and cheese from goats, sheep, and Guernsey cows).  Legumes (beans, peas, and peanuts) aren’t included in the paleo diet, but the lectins can be mostly soaked and cooked out, and they’re packed with antioxidants and other nutrients.  I stay away from soy  (which can mess with hormones) and red kidney beans (packed with toxic lectins), but I sometimes eat green beans, peas, pinto beans, and peanuts.

When I eat out at restaurants, I’ll order protein and vegetables instead of pasta, but if the bread is good I’ll eat a piece.  I have less of a sweet tooth than I did in my starch-binging days, but I still have one — so I eat ice cream or pie once in awhile.

Even with fairly frequent “cheats,” I now breathe easy, and I’ve kept off the extra twenty pounds.

I do need to be careful not to eat too many foods that are naturally high in serotonin, such as plums, bananas, avocados, kiwi, tomatoes and a few others.  These foods can’t raise your brain serotonin, but they can boost your plasma (blood) serotonin, thus possibly triggering bronchoconstriction and asthma symptoms.

I still take supplements — both for general health and to make sure I stay free of breathing problems.  Most important are fish oil (to keep the Omega-3/Omega-6 fatty acid balance tilted towards Omega-3), and magnesium (which has a host of other benefits, like preventing noise-related hearing loss).

What Does “Cure” Mean?

You might object to my use of the word “cure.”  Have you really cured a disease if it can come back at any time?  If you have Type-2 diabetes, and you “cure” the disease by sharply reducing your dietary glycemic load (eating less sugar and starch), and exercising regularly, is it really cured?

Take cancer, for example.  Our bodies are constantly producing cancer cells, but our immune systems generally keep them in check.  We never totally rid our bodies of cancer cells, or bacteria, or viruses, or inflammation, or any of the other factors that cause disease.

You can “cure” scurvy with vitamin C, but the scurvy will come back if you stop ingesting vitamin C for long enough.  You can “cure” a bacterial infection with antibiotics, but those bacteria still lurk in the environment (or on your skin, or in your intestines) and can reinfect you at any time.

I used “cured” in the post title, but I could have also used “healed,” or “completely manage my symptoms.”  I’m still vulnerable to asthma if I eat large amounts of the wrong foods, or inhale gigantic amounts of certain pollens.  But on the whole, I feel like I’ve cured the disease in myself.

If you (or a loved one) have experienced asthma symptoms, I feel for you, and I hope you find this post to be useful.  Even if a modified paleolithic diet doesn’t work for you (or you don’t want to try it), don’t give up.  Keep trying things — don’t settle for an inferior quality of life.  If you find the right combination of factors, the body is capable of healing itself.

Pick the Low-Hanging Fruit, Part II (Health) — continued

Berry berry yummy.

This post is a continuation of Pick the Low-Hanging Fruit, Part II (Health).

4. Reduce artificial light in the evening.

Are you sleep-deprived?  Do you “try to go to bed earlier” and fail, night after night?  I’ve been there.  If you enjoy browsing the internet or watching TV or playing video games or even just reading, you may, like many other people, fail to get sleepy in the evening (even when your body and mind are exhausted).  You know what’s keeping you up?  It’s the artificial light (blue spectrum light in particular).  At least according to this book, the blue light (equivalent to day light) is blocking the serotonin to melatonin conversion process — and the melatonin is the hormone/neurotransmitter that tells your body it’s time to go to sleep (and makes you feel sleepy).

I’d always thought of myself as a “night owl” until I tried an experiment; go without artificial light in the evening.  I found that without light bulbs, the TV, or the blue glow of the computer screen keeping me up, I would often be yawning by 9pm (otherwise my “natural” bedtime would be midnight or 1am).

The experiment I conducted was not easy.  But there are two very easy steps you can take in the same general direction.

  • use fewer lights in the evening — no need to have the whole house ablaze
  • download and install the free f.lux software on your computer — if you do then it won’t be your computer that’s keeping you up!

5. Exercise intensely 1-2 minutes a day, at least a few times a week.

All the latest exercise physiology research is pointing to these two general conclusions:

  • intensity (achieving maximum heart rate, lifting maximum weight) is more important than duration
  • less is more (recovery time is very important, over-training is very damaging)

If you really go for for that 1-2 minutes, you’re going to achieve MOST of the benefits in the following categories:

  • cardiovascular fitness (maximize heart rate)
  • strength (maximize weight lifted, move very slowly and with good form, stress muscles to the point where GH is released)
  • bone density  (especially with jumping or sprinting — both stress and thus strengthen the long bones)

What qualifies as intense?  Sprints, jumping and leaping, body-weight exercises (pullups, pushups, chinups, bar dips, etc.), carrying/lifting/pushing heavy objects, running up stairs — that sort of thing.  The best exercises are the ones that you actually enjoy doing — don’t bother with exercises that feel uncomfortable, boring, etc.

Most of the people flogging themselves in the gym aren’t improving their health.  Instead, they’re spiking their cortisol levels, stressing their joints, overburdening (and possibly enlarging) their hearts, and probably boring themselves to death in the process.

6. Floss before you brush.

My “floss every day” intention used to lead to flossing three or four times a week.  I would wait until right before going to sleep to brush my teeth, and half the time after brushing I would be too tired or lazy to floss.

Gum health is massively important for overall health.  Even mildly inflamed gums can raise your risk of heart disease (“leaky gums” are an open door for pathogens to waltz right into your bloodstream, thus giving your immune system a constant low-grade battle which can lead to chronic inflammation and the formation of arterial plaque).  Even knowing this, AND having a family history of both heart disease and gum problems, wasn’t enough to get me to religiously floss every day.

The trick that worked for me was switching the order.  I don’t think I’ve missed a day since.  Flossing doesn’t seem difficult anymore, because I’m not waiting until I’m exhausted to do it.  Even more important is anchoring the less ingrained habit (flossing) to a more ingrained habit (brushing).

One other thing I’ve noticed is that flossing is easier and faster if I’m not looking in the mirror.  Something about the visual feedback slows down the process — I can floss more quickly (and just as thoroughly) by touch alone.

The low-fat diet is just crazy.

7. Eat more fat.

In general, carbs (sugars and starches, including bread and pasta) cause the release of insulin, which lowers your blood sugar.  This makes you want to eat more carbs.  Eating dietary fat, on the other hand, leads to the sensation of fullness.  It’s easier to avoid overeating if you tilt the balance away from carbohydrates and towards healthful dietary fats.

There are a few types of dietary fat you want to avoid, including trans fats (hydrogenated vegetable oil), highly processed fats (like canola oil), old/rancid fats (processed vegetable and seed oils are especially vulnerable), and overheated vegetable/seed oils.  These oxidized fats can damage your health in a number of ways.

The good news is that most fats that are delicious are also health-promoting, including butter (especially from pastured cows), olive oil, coconut oil, fatty fish, chicken fat, and beef fat (again, especially from grass-fed/pastured cows).

Keeping a good ratio between Omega-3 fats (from wild-caught fish and grass-fed animal sources) and Omega-6 fats (from nuts and seeds, seed oils, and grain-fed animal sources) will support overall health, including immune function, heart health, mood, and blood sugar regulation.  Most people consume too much Omega-6 and not enough Omega-3.  Taking supplemental fish oil is the easiest way to improve this ratio (you can check out this site and this study to see which brands are best and which ones to avoid).  Keep fish oil refrigerated.

These days the prevailing wisdom says that we should avoid saturated fat to maintain optimum health and avoid heart disease, but the actual evidence behind this claim in extremely weak.  Most of the studies that claim saturated fat harms our health don’t control for intake of salt, refined flour, trans-fats, sugar, high-fructose corn syrup, and processed food.  For example, a typical dietary study might compare the health of people eating the Standard American Diet (S.A.D.) to the Mediterranean diet — in other words hamburgers, hot dogs, white bread, corn oil, soda VS. fresh fruits and vegetables, fish, olive oil, beans, and whole grain. Conclusion: saturated fat is bad for you!  Really?  What about all the other junk on the S.A.D. side?  What about all the protective effects of the healthful foods on the Med side?  Studies like this don’t prove anything about saturated fat in particular.  Next time you see a headline that proclaims the evils of saturated fat, drill down and take a look to see what foods were actually being consumed by the study participants.

The original Ancel Keys “7 countries” study that got us collectively believing in the evils of saturated fat was based on cherry-picked (in effect, falsified) data.  Ancel Keys only included data from countries where both dietary saturated fat and heart disease were high — and left out data from countries where dietary saturated fat was high and heart disease was low.

The latest clinical research shows there is no relationship between eating saturated fat and getting heart disease.  Here’s the direct link to the meta-analysis.

For detailed discussions and numerous citations to the studies behind these assertions about dietary fat, I encourage you to explore Dr. Eades’s site and Mark Sisson’s site.  That is, if you like butter, and bacon.

Pick the Low Hanging Fruit, Part II (Health)

A small serving of fruit.

In my first post in this series I wrote about “low-hanging fruit” in regards to charitable giving.  I shared my opinions regarding which organizations are working effectively and transparently to improve people’s lives by tackling big problems with relatively straightforward solutions.

Today I’ll write about applying the same “low-hanging fruit” principle to personal health.  What steps can we take to improve our health, energy, longevity, and vitality that aren’t that hard? Why not start with the easy stuff?

Personal health regimens often appear to be complicated and difficult, but I think that for most of us there are easy steps we can take that can radically improve our health.

1. Get your vitamin D levels up to between 40-60 ng/ml.
Up to two-thirds of people in the U.S. have “sub-optimal” levels of vitamin D — not low enough to result in rickets but low enough to increase vulnerability to certain types of cancer, reduce bone density, reduce immunity, and negatively affect more or less every organ in the body.  If you’re curious, search for the studies online and read the opinions of various medical experts.  Quite a few doctors and researchers have A LOT to say about this topic, and there is no shortage of clinical research.

My personal experience of taking 5000IU a day (I take one 5000IU capsule a day, along with fish oil or sometimes cod liver oil) over this last winter is the following:

  • deeper, more restful sleep
  • general better mood (very little “feeling down” and frequent “happiness for no discernible reason”)
  • no serious colds and no flu (a couple times this winter I felt almost sick for a couple days, but never “full blown”)
  • cessation of asthma symptoms (most of my asthma symptoms went away after switching to something more closely resembling a paleolithic diet, but I don’t think I’ve had a single flare-up since starting on the vitamin D)

I’m also impressed by the inverse relationship between vitamin D levels and many types of cancer.  I’ll get my blood level checked at my next checkup and see what the results are … if they’re above 60 ng/ml I’ll back off on the supplementation as there can be negative effects from blood levels that are too high.  However some doctors say that keeping levels as high as 60-90 ng/ml is ideal.

A full winter’s supply of vitamin D shouldn’t cost you more than $20 or $30.  One pill a day if you take the 5kIU size, and it’s no big deal if you miss a day.  You also want to make sure you’re getting enough calcium (sardines, canned salmon, dairy, greens, almonds) and magnesium (greens, cocoa/dark chocolate, nuts and seeds, beans) in your diet.

If 5000IU seems high (it looks high compared to the U.S. RDA), consider that 20 minutes of sun on your bare skin can generate up to 20,000IU (depending on a number of factors, including how tan or naturally dark you are, time of year, time of day, latitude, how much skin is exposed, etc.).  You generally get enough vitamin D from the sun before you burn (vitamin production shuts down so you can’t get too much this way).

2. Start consuming green tea, dark chocolate, and/or red wine on a regular basis.

C’mon, you’ve got to enjoy at least one of these flavors, no?  While pill-form antioxidants have come up short in clinical studies, regular consumers of these three antioxidant-packed foods show lower risk for heart disease, cancer, and dementia.  The relatively low amounts of sugar, caffeine, and alcohol in these foods will do you less harm than the polyphenols will do you good.

If you find the taste of green tea to be too bitter, you’re probably brewing it wrong.  Get loose-leaf tea from China, quickly rinse it with very hot water (not quite boiling), then brew it for as short a time as 30 seconds.  Brewing too long or using fully boiling water can result in a bitter taste (though both methods will also increase polyphenol content, so you have to find a balance).

In terms of red wine, this page presents a good overview of which varietals contain the highest levels of polyphenol antioxidants.

With chocolate, the processing method can remove many of the healthful antioxidants.  I like to make hot cocoa out of minimally processed “raw cacao” (I don’t know what’s up with the funny spelling — that’s why I put it in quotes).  There are several brands but I’ve been buying the Navitas brand for awhile and I like the taste.  For one mug I use about 2T of the unsweetened powder and 1t sugar, boiling water, and a little whole milk.

3. Hang out more with your friends.

Commenting on your friends’ FB status updates doesn’t count.  But real social networks, the kind where you actually hang out and do stuff (or even just sit around and gossip) with your friends, is associated with longevity, lower blood pressure, reduced stress, lower risk of depression, and all kinds of good stuff.  And it makes life more fun.

If your “friends” like doing meter-long rails of cocaine, rows of Jager-bombs, crime, or extreme vertical-cliff snowboarding, this one might not apply.  Find a good Settlers of Catan group or something.

Coming up next …

I’ve been advised to keep my posts shorter if I want to keep your attention, so I’ll save 4-7 for the next post.

A Meta-analysis of Kooky Diets, Part III — PALEO!

This post is a continuation of A Meta-analysis of Kooky Diets, Part I and Part II.  In this post I’ll discuss three proponents of the so-called Paleolithic Diet.  In Part II I introduced the Paleolithic Diet and discussed its core concepts — if you’ve never heard of it you might want to read that post first.

Meat. Not required as part of the Paleolithic diet, but not discouraged either.

In short, the Paleo Diet is a method of eating that excludes foods that were not widely available or consumed by our pre-agricultural ancestors, such as grains, legumes, dairy products, refined sugar, oil, and salt, instead favoring non-starchy vegetables, less-sweet fruits, meat, fish and seafood, poultry, eggs, nuts, and seeds.

Personally, I no longer find this way of eating to be “kooky” in any sense.  When I first heard about it, it seemed both radical and silly.  Sure, it’s reasonable to cut back on white sugar and white flour, but to also cut out whole-grains?  Wholesome oats and brown rice are out?  Whole-grains are good for you, aren’t they?

Whole-grains may be good for you when compared to eating refined grains, and that’s what most of the research examining the health benefits of whole grains has looked at.  For whatever reasons, few researchers have compared a diet including whole grains to a diet including no grains.  Those that did found that a grain-free diet led to rapid weight loss, improved glucose tolerance, faster muscle gain, and a number of other benefits (please see Part II for links to clinical studies).

The Paleolithic Diet has been around since the 70’s, but more recently a number of Paleo evangelists have been spreading the word; grain-free is the way to go.  I’ll introduce three of these health nuts and you can draw your own conclusions.

Arthur De Vany

I first became aware of Arthur De Vany after reading an interview with him about nutrition and exercise, and seeing the picture on the right.  A guy approaching seventy who looks that ripped?

Arthur De Vany, at age 68, going for a quick sprint.

There are plenty of meatheads in their twenties or thirties can develop a ripped physique, even if their diet includes Pop Tarts and pasta.  Decent genetics, lots of working out, maybe some steroids, and BAM! there you go — comic book muscles.  But Art De Vany — he seemed to defy aging.  It got me, and a lot of other people, very curious.

I began reading Arthur De Vany’s blog at http://www.arthurdevany.com.  I learned about his system of health dubbed Evolutionary Fitness, based on a “Paleo-Med” eating plan (a cross between Paleolithic diet and Mediterranean diets) and short, irregular bouts of intense physical exercise, with an emphasis on weight-lifting, sprints, jumping and leaping, and no distance running or jogging (the latter two being actively discouraged).  He also blogged about more personal things, including his beloved wife passing away, his frustrations with his incompetent softball team, and his occasional trouble with insomnia.  His blog included a wide range of intellectual ideas; he shared his opinions and theories about teaching, Hollywood economics, evolution, climate change, and a number of other topics.  I use the past tense because he has since made his blog private — its popularity was resulting in excessive bandwidth fees and occasional outages.  Art De Vany himself is still going strong — and you can still read his blog if you don’t mind paying the subscription fee.

One interesting feature of his previous public blog is that he would occasionally post a picture of a meal.  At first Art seemed a bit baffled — why were those simple posts so popular?  His readers kept requesting more pictures of his meals.  The fact is that it’s hard to imagine what a grain and starch free meal looks like if you’re used to eating cereal and milk for breakfast, a sandwich for lunch, and pasta for dinner.  Seeing pictures of Art’s breakfasts (maybe an omelet with fruit on the side, or a pork chop with half a melon, usually with a cup of black coffee), and lunches and dinners (colorful salads, grilled vegetables, sizzling steaks, racks of ribs, slices of avocado, olives, sometimes a glass of wine or a beer) helped me and a lot of other people think more creatively about our meals.  That’s what a diet is, after all, it’s meals.  You’ve got to put food on the table three times a day, and like it, in order to stick to any kind of eating plan.

There was an ad I saw about ten years ago (I forget what for), a picture of a juicy steak like this and the caption was “the new health food.” No longer so shocking …

At the time I was reading his blog on a regular basis, Art De Vany’s version of the Paleolithic Diet included lean meat, poultry and eggs, seafood, nuts, non-starchy vegetables (both raw and cooked), and fresh fruit.  Olive oil and olives were included, as well as some wine and cheese (the “Med” part of “Paleo-Med”).  De Vany, at least at that time, limited his saturated fat intake by trimming the fat off of his steaks, and preferring low-fat cheeses such as Jarlsberg.

For supplements, Art De Vany takes (and recommends) cod liver oil and l-glutathione, the first for its Omega-3 and vitamin A content, the second for its antioxidant and anti-aging properties.  He also recommends Mark Sisson’s supplement pack, which is how I came to learn about Sisson (who I’ll discuss next).

Art De Vany is an interesting character.  His writing style can come off as over-authoritative, but at the same time he’s obviously well-educated and extremely knowledgeable.  I heard a radio interview with him, and was surprised by how soft-spoken he was … somehow I expected a more macho or at least enthusiastic tone.  How to put this … he’s like a nerd-athlete hybrid.

Art De Vany’s views around climate change have generated some controversy.  His opinion, as I understand it, is that most models of climate change are bunk; there is too much randomness and there are too many variables that influence climate to be able to generate a reliably predictive model.  This opinion has somehow “rippled out” among the “Paleo community” as it is; there seems to be a large of number of “climate skeptics” or “global warming deniers” — whatever you want to call them — among Paleo diet enthusiasts.  Maybe it has to do with people who identify themselves as bucking the status quo and thinking differently from the mainstream.  Or maybe it’s the macho thing, eat meat and drive a big car?  I really don’t get it.  The logical approach to environmental issues if you are a skeptic of global warming models is extreme conservationism, as outlined here (see entry #120) by Nassim Taleb (the author of The Black Swan, and also a follower of Art De Vany’s Evolutionary Fitness program).

I’m glad I discovered Art De Vany’s site … it influenced me to eat more healthfully and helped me imagine what a meal without a “pile o’ starch” could look like.  But it wasn’t until I started reading Mark Sisson’s blog, marksdailyapple.com, that the Paleolithic Diet really came together for me.

Mark Sisson

Mark Sisson is a former professional athlete (distance runner and triathlete) who now writes a popular blog at marksdailyapple.com.  He’s written a number of books on diet and exercise, and also runs a supplement company called “Primal Nutrition.”

Mark Sisson doesn’t seem to own any shirts.

He’s 56 and in very good shape.

His blog is an abundant (and sometimes overwhelming) source of information.  He’s not kidding about the daily part; there really is a new, detailed post every day.  Topics are centered around what Sisson calls the “Primal Blueprint” — his holistic plan for total health that is based on his version of the Paleolithic diet — but also branch out to cover a vast array of health-related topics.

Sisson’s version of the Paleolithic Diet is comparatively easy to follow.  He recommends cutting out grains, legumes, potatoes, and refined sugar almost entirely, but moderate amounts of coffee, tea, wine, beer, salt, dark chocolate, and even cheese are not discouraged.  Sisson comes right out and says that a Paleo Diet should be a high fat diet.  The first time I read that, I remember feeling skeptical, but those two words turned out to be the key for me to personally adopt a Paleo eating style.  Before I started using more olive oil, butter, coconut oil in my cooking, and eating fattier cuts of meat and more fatty fish, I would just get too hungry if I wasn’t eating breads and cereals.

Sisson also recommends supplementing with fish oil.  In fact, he recommends supplementing with just about everything.  Check out the ingredient list for his top-selling supplement “Damage Control Master Formula.”  If those doses are

If I ate like this every night I wouldn’t have to take any fish pills.

supposed to be daily, some of them strike me as too high.  The water-soluble vitamins aren’t a problem, but trace minerals like zinc, copper, selenium, and manganese can build up in the body and have toxic effects.  This article references symptoms of manganese toxicity occurring in individuals drinking water with levels as low as 2mg/liter (each dose of Damage Control Master Formula has 10mg).  On the other hand, the same article points out only one case of manganese toxicity from supplement use, and none from food, so maybe 10mg/day is a reasonable dose.

Questions of dosages aside, Sisson gives the impression of genuinely caring about the health of his readers and customers — I don’t doubt his claim that his supplements contain fresh, high quality ingredients.

There is definitely a sense of community among the readers of Sisson’s blog — people supporting each other in a lifestyle choice that many people view as radical (for some reason people are more threatened by the idea of the Paleolithic diet than they are by vegetarianism).  Sisson often shares reader testimonials — like this one which I found to be quite moving.  It parallels my own experience — feeling that my body was somehow permanently damaged or broken (with adult-onset asthma and allergies in my case) and then experiencing a total cessation of symptoms within days of changing my diet.  A “second chance,” a “new lease on life,” — those phrases don’t do the feeling justice.  Here’s a brand new bodyone that works! That’s more what it felt like.

Mark Sisson’s blog is a great source of information, and his tone is friendly, non-dogmatic, and nonjudgmental.  If a friend or family member expresses interest in changing the way they eat, I usually refer them to marksdailyapple.com

Loren Cordain

Dr. Loren Cordain is a professor in the Department of Health and Exercise Science at Colorado State University, and is the author of The Paleo Diet, a popular book published in 2002.

Dr. Cordain, rockin’ the center part.

Cordain’s take on the Paleolithic diet is similar to both Art De Vany’s and Mark Sisson’s.  He suggests that genetically, human beings are poorly adapted to eat grains, beans, dairy products, alcohol, and salt, and recommends eating fruits and vegetables, lean meat, seafood, poultry, nuts, and seeds instead.

In the Paleo community, Cordain’s view that saturated fat intake should be limited is controversial.  In The Paleo Diet, Cordain clearly puts saturated fats in the “bad fats” category, along with trans fats and polyunsaturated fats like corn oil (as opposed to “good fats” like Omega-3 fish oils and monounsaturated fats like olive oil and avocado).  In the same book he argues that wild game is quite lean as compared to domestic cattle.

Since then, it seems that Cordain’s view on saturated fats has become more nuanced.  If you carefully read the FAQ on his website you’ll see that Cordain no longer recommends reducing saturated fats.  He seems to consider them more “neutral” than “bad” at this point, and concedes that prehistoric humans probably preferred fattier meat when they could get it (this coincides with the Inuit’s warnings regarding the overconsumption of lean winter caribou as discussed in my previous post A Meta-analysis of Kooky Diets, Part I).

Cordain still holds to the view the eating lots of bacon, sausage, and other salty, fatty meats is no good for health and may raise the risk of heart disease.  To me this seems reasonable, despite the fact that it overlaps with conventional dietary wisdom.

Cordain has some interesting views regarding tomatoes.  Unlike other Paleo advocates, he considers them a neolithic food (my wife Kia challenged this assumption when she heard it — tomatoes had to grow in the wild somewhere and someone must have been eating them since pre-agricultural times.  The Department of Horticulture at University of Wisconsin-Madison agrees with her — early inhabitants of what is now Peru probably dined on wild tomatoes.)

Beautiful, delicious, and … evil?

In any case Cordain consider the lectin in tomatoes (which, by the way, is impervious to heat) to be harmful to human health.  He views the peanut lectin, the protein casein in milk, and grain lectins with equal disdain, but we already knew those foods were not allowed for wannabe cavemen, didn’t we?  But the delicious and healthful tomato?  Packed with vitamin C, potassium, lypocene, and glutathione?  Really?

If you have the time, and can stomach it, watch Cordain’s hour long lecture on lectins and multiple sclerosis.  It’s fascinating (and disturbing).  He explains in great detail how various lectins make their way into the bloodstream and interact with the immune system, essentially tricking your own body into attacking itself.  I used to use a great deal of tomato paste in my cooking — I don’t any longer after watching the video of his lecture.  I still sometimes eat fresh tomatoes though, as long as they’re ripe.  (Did you know green tomatoes have a poison calls solanine in them?  Yes, fried green tomatoes = poisonous snack.)

SUMMARY

There are a number of criticisms of the Paleolithic Diet, but most of them are quite weak.  The low-fat diet recommended for the past several decades by official sources in the U.S. has been largely debunked; in practice it has led to massive weight gain, greater instances of Type 2 diabetes, and no appreciable reduction in heart disease or cancer.

Sometimes the Paleo diet is lumped in with Atkins, but this doesn’t make sense; unlike Atkins the Paleo diet is rich in antioxidant-packed fruits and vegetables, is low in salt, and very low in processed foods of any type.  It is generally low-carb, but far from zero-carb (Sisson recommends keeping carb intake between 50 and 100g/day if you want to lose body fat, up to 200g/day depending on your size and muscle mass in order to maintain).

One criticism that I consider to be at least semi-valid is the fact that humans have evolved biologically in the 10K years or so since we invented agriculture.  Some of us have genetically adapted to our “new” neolithic diet, at least to some extent.  I, for one, have no problem digesting lactose.  I’m lactose tolerant — I inherited the “right” genes from my European ancestors who co-evolved with cattle (less than 25% of humans carry this gene, and yet we talk about “lactose intolerance” as if it were some kind of rare disorder!).  People whose ancestors evolved in agrarian societies tend to have more copies of the gene that helps produce amylase, the enzyme in saliva that breaks down starch.  This is one example, discussed in this NY Times article, of how culture and the human genome co-evolve.

That’s the big picture — we push against our environment, our environment pushes back, and we either adapt ourselves, or change our environment, or both, or we perish.  Human beings haven’t stopped evolving genetically.  In fact, we’re changing faster than ever.  Still, genetic change happens slowly, over many generations, and it’s obvious that the modern industrial diet of highly processed, high-carb fake food is not the ideal fuel for the human body and mind.  Paleo diet advocates (myself included) would go further and say that the relatively “new” foods like grains, legumes, dairy products, and nightshade vegetables, while they may not be harmful in small amounts, are not ideal staples (and for most people in the world they are staples).

Another possibly valid criticism is that not everyone in the world can afford to eat a diet that is high in protein and low in grain.  This might be true — we know that the world’s fisheries are overburdened, and also that it takes a great deal of water, pasture and/or grain to raise a cow, but these facts must be weighed against the following counter-arguments.

  • The collapse of the world’s fisheries has as much to do with poor ocean resource management (a lack of protected areas, poor enforcement of existing protections, wasteful and destructive fishing practices, etc.) as it does with how much fish we eat.
  • Growing grains and beans takes up an enormous amount of land and water and fossil fuel fertilizers and pesticides; intensive polycultural farming techniques that produce meat, vegetables, and eggs might give us more food in exchange for less land and water, and improve the soil quality while we’re at it.
  • The number of overweight people in the world (not just the U.S.) has reached epidemic proportions.

Some of use may be better adapted to “modern” foods, but most people would probably experience health improvements if they switched to a diet that more closely resembled what our distant ancestors ate.  I think groups who would most benefit from a Paleolithic diet, in order, would include:

  1. Anyone with a direct intolerance of gluten, anyone with celiac disease, anyone with IBS, anyone who has noticeable trouble digesting grains and/or dairy products
  2. Anyone with an autoimmune disorder of any kind, including multiple sclerosis, arthritis, lupus, asthma, or allergies.
  3. Anyone with (or at risk for) Type 2 diabetes, Metabolic Syndrome/Syndrome X
  4. Anyone who wants to reduce their risk of heart disease, cancer, and dementia
  5. Anyone who wants to gain muscle, lose body fat, have more energy, have clearer skin, not get sleepy after meals, sleep better at night, have a higher sex drive, and feel happier.

Did I leave anyone out?
