Mark Sisson Is Not Afraid of Fat

Evolution is all about adaptation – to the environment, to circumstances, to stress and even (or especially) to food. In this context of adaptation, it’s truly amazing how “inventive” the human body has become in finding novel (and perhaps heretofore uncontemplated) ways to repair damage we do to ourselves through our diets and other lifestyle indiscretions. And most of these changes are less than a few hundred years old, which makes the adaptations even more remarkable.

Let’s use cholesterol as an example. Cholesterol is actually very beneficial. Among other duties, it’s a necessary component of every cell membrane and it’s involved in hormone production. The body makes about 1400 mg a day just to keep up!

Now let’s take a stressful lifestyle (show of hands, please), add in a bad diet and lack of exercise and we get an inflammatory process in the arteries that causes lesions. This inflammation problem is completely unrelated to amounts or types of cholesterol.

Nevertheless, the ever-inventive human body adapts to this inflammation sequence by using cholesterol as a band-aid to cover up the lesions until healing can take place – which, of course, almost never happens since the silly human continues to live the same pro-inflammatory lifestyle. Eventually, the cholesterol band-aids harden (sclerosis), narrow the arteries and sometimes break off causing a heart attack.

Of course, we blame the cholesterol for all this and embark on a national campaign to rid the body of this important substance instead of focusing on the foods (and other stresses) that promote inflammation in the first place!

Now let’s consider fat. For years we believed fat was nothing more than nature’s way of storing extra calories for some future famine. That would be a handy little adaptation in and of itself if that’s all it were. But when you do the math, you see that it doesn’t require a lot of fat to survive or even migrate for long periods. A 165-pound person with only 13% body fat has 21.45 pounds of fat. Being generous and assuming that you need a minimum 3% just to carry on basic survival functions, that leaves 10% or 16.5 pounds of fat to live off. At 3500 calories per pound of fat and 100 calories per mile walking, you’d theoretically have enough fat to survive weeks and migrate several hundred miles.

So maybe fat has another purpose, and this is where my friend Art De Vany’s description of fat as a toxic waste site (my words) comes in. Modern humans have so thoroughly altered foods to focus on simple carbohydrates (sugars) that we now consume hundreds of excess grams of it every day.

As Art has explained, the body recognizes excess sugar (glucose) as a toxic load – and remember, it doesn’t take a whole lot of it to be excessive – and the body starts the adaptive process of secreting insulin to take sugar out of the bloodstream and deposit it into the muscles.

Two problems arise immediately:

First, there’s not a lot of room in those muscles. Ask any athlete who’s ever tried to carbo-load for an event. Secondly, most people aren’t athletes and have lost significant utility of their muscle through atrophy, further diminishing storage. Furthermore, they don’t burn off the already-stored glycogen because they don’t exercise.

But here’s where the body has become so elegantly adaptive once again. It creates little storage facilities in the form of additional fat cells. Not because it’s trying to store calories for some future famine, as modern medicine might have you believe, but because it’s trying to find novel and effective ways to rid the body of this very toxic glucose excess.

And it’s a pretty good solution. Insulin allows glucose access to these fat cells which grow larger and more numerous over time. Problem is, it’s always one step behind, so the fat cells fill up just as the muscle filled up, leaving excess glucose in the bloodstream after the next high carb or high calorie meal until more fat cells can be made.

And so the spiral continues as 40 million Americans are headed towards type 2 diabetes.

The Bitter Swiss

SMART FUEL

Swiss Chard

Don’t let the spinach scare stop you from getting copious greens in your diet. I recommend trying out chard in replacement of spinach, regardless of the current health scare.

Chard is actually a member of the spinach family, but it is more substantial and greater in nutritional value than regular spinach. I’m always amazed at how inexpensive chard is, too – even the organic variety. For recipes, you’ll find chard’s texture is better than spinach, too – it doesn’t get stringy or mushy.

Chard packs a lot of nutritional density for bone health, so it’s appropriate given our osteoporosis discussion. Chop it up, throw it in any sauces, risottos or stir fries, and enjoy high levels of vitamin K, A, C, iron, calcium, potassium, manganese and magnesium. Chard is also the most fibrous leaf you can eat. Try it out this weekend.

Who you callin' bitter?

Eggs Are Good for More Than Silly Cliches

SMART FUEL

People like to use eggs in words like eggscellent, eggxactly and eggstatic.

Poor eggs. I recommend using them in your meals instead – and think beyond breakfast on occasion. Eggs are slowly regaining favor after their Humpty-Dumpty fall during the whole cholesterol paranoia of the 1960s, 70s and 80s.

We know that they contain valuable protein, vitamins and minerals: stress-busting selenium, antioxidant E, and eye-healthy lutein among them.

Because I am an egghead (sorry), I’m proud to bring you the latest findings from a study Mark pointed out to the Bees in the Journal of Nutrition. In a study that was randomized (good), controlled (great), and cross-sectional (nice), scientists found that a daily egg gave people’s eyes a boost with lutein and zeaxanthin (an antioxidant from the carotenoid family) and didn’t raise their serum cholesterol. Not that we worry too much about cholesterol anyway. That’s right – we don’t lose sleep over cholesterol! Just one of the many MDA ongoing health debates you might want to check out in the forum.

Whip yourself into shape!

Uncle Sam – Definitely Not a Pisces

Something I read in the New York Times the other day got me steamed faster than fresh spinach. Apparently, fish oil prescriptions are not only standard practice in Europe – they’re handed out like candy corn on Halloween – but heart patients who don’t get a prescription can actually sue for malpractice.

Pure fish oil is so clearly supported by the international body of science that European doctors who don’t prescribe the stuff to anyone worried about their cardiovascular health are considered grossly incompetent.

Hundreds of peer-reviewed studies support fish oil for great health. Some of the healthiest peoples in the world – from Japan to the Mediterranean – rely heavily on fish fats for great health. Fish oil = better body is not some radical new idea, but try telling that to the American health business. Er…health establishment.

Now, this doesn’t really surprise me; after all, the safest, longest-lasting, most effective, non-drug form of birth control favored in Europe and tested safe for decades is also basically nonexistent here in the Fabulous 50. America may have the best life-saving surgery techniques in the world, but when it comes to basic illness recovery or health maintenance, one would think fish oil must be some risky, mind-altering substance right up there with caffeine and alcohol. The difference being those are both substances prescribed by doctors.

I’m not asking a lot of our federal government. I know they have lobbyists to cuddle. But would it kill anyone over at the FDA or the N.E. Journal of Medicineyness to admit that fish oil has excellent therapeutic properties for people in general and heart patients in particular, and – gasp – recommend prescribing the stuff? They accept the data. Why not recommend?

Here’s the part of the article that really burned my mocha:

“For example, on Solvay Pharmaceutical’s Web site for Omacor (a Euro fish oil supplement), the first question a user sees is ‘Are you a U.S. citizen?’

If the answer is yes, the user is sent to a page where heart attacks are not mentioned.”

I’m so thrilled with our government for censoring accurate scientific information about cardiovascular health on a European company’s website so we citizens can remain both ignorant and unhealthy. Fish fat in its pure form is vital to cardiovascular health, brain health, and the strengthening of the linings of cells. Considering the damage that free radicals and inflammation whack cells with every day, and the difficulty in getting low-mercury fish filets at the local market, wouldn’t recommending and even prescribing fish oil be a prudent thing for the medical “establishment” to do?

Thanks to Elisabeth Rosenthal at the Gray Lady (the Times) for this piece. To the rest of you, get thee to a fish oil supplement, stat!
