Things you KNOW, that are no longer valid

Many of the things we know and believe, and have acted on, are no longer scientifically valid.

Good News: Everyone can learn what the best new science is.
True, all the problems have not been solved, but it's better if we can reduce the barriers to our success.

Whole Grains are Healthy.

That may be true in the early years of one's life. Over time, too much of a good thing, apparently produces a reaction in the body, an intolerance, sometimes to gluten, but also a wider intolerance to wheat, and all carbohydrates.

Local FileMetabolic syndrome is an indication that this intolerance is developing.

Local FileType 2 diabetes, is evidence that carbohydrate intolerance is severe. Another way to discuss this is to call it insulin resistance. The body is less and less able to use insulin to transport the available glucose into your cells. Insulin is produced, but it's increasingly ineffective.

Research into Local Filelow carbohydrate diets, or ketogenic diets stopped about 1928, and began again about 1998. The idea that people might Local Filechoose to eat a diet that sustains ketosis, is relatively new.

If simple weight control is your problem, start to do something about that now. Local FileChange what you eat for breakfast, and keep burning fat off your body until at least lunch time.

The Great Cholesterol Debate

If HDL-Cholesterol is protective, we can call it "good cholesterol."

So LDL-Cholesterol is "bad" and almost everyone is prescribed a statin to reduce their CVD risk.

Mistake

It's now well known that Local Fileany effort to reduce cholesterol levels by diet cannot succeed. Your body produces its own cholesterol independent of your diet.

The link between LDL-Cholesterol and CVD is tenuous. Both the Lyon Heart Study and the Local FileWomen's Health Initiative show no effect of LDL-Cholesterol of CVD.

If there is any risk at all in LDL-Cholesterol, it arises from small dense particles it can carry.

The things you KNOW

Low-fat diets are healthy.

MistakeIn young people, the often recommended low-fat, high-carbohydrate diet, usually works well. However, over a lifetime, in modern societies, that seems to change, and people become carbohydrate intolerant. Your hormones work against you, and you begin to get fat.

For most older people, it's been demonstrated that Local Filethe "recommended diet" has no health benefits.

Worse than that, because it's making us fatter,Local Filethe "recommended diet" is probably making us sicker.

Vegetarian Diets are the Healthiest.

Vegetarian diets are very hard to maintain. Vegetarians usually lack the fat-soluble vitamins, A, D,E, and K.

Local FileThere's a host of reasons why it's unwise to become a vegetarian.

Saturated Fats are BAD.

Saturated fats are supposed to make people fat and clog the arteries. That's untrue. In the absence of insulin, saturated fats become the main fuel for your body.

In the presence of insulin, fats are broken down into Local Filefatty acids, and they should be stored in the adipose tissues within the body. However, as soon as that begins to happen, the hormone leptin in released Local Filewhich signals the appestat to stop you eating. (You should NOT get fat.) That mechanism fails if there is too much glucose in the blood. Insulin over-rides the leptin signal in order to burn or store more glucose.

Local FileThe Framingham Heart Study dismissed diet as a cause of heart disease in the 1980s.

There is no relationship between diet and Local FileCardiovascular Heart disease.

There is no relationship between dietary saturated fat and heart disease.

Vegetable Oils are better than Butter.

Not so. Vegetable oils are less stable, usually mono-unsaturated, or poly-unsaturated, rather than Local Filesaturated fats, and they may create undesirable by-products when heated.

To make them stable for baking and frying, or for margarine, vegetable oils are hydrogenated, to change their chemical structure. Once thought to be safe, and cholesterol lowering, they are now considered dangerous, by many researchers.

Hydrogenated oils are known to produce great numbers of artificial chemical byproducts when heated. Nobody has been able to test but a few of these. Some are certainly carcinogenic.

Thirty years ago hydrogenated oils were everywhere. Your fish and chips were cooked in them. All baked products from commercial kitchens contained them. They were heavily promoted and thought to be "healthy."

Because the bad health effects of hydrogenated vegetable oils are now better known, their use has declined.

Today your food is probably cooked in palm kernel oil, or palm oil. From a health point of view, that might be good. These oils have a high smoke point, and because they have a lot of saturated fat, they will be much more stable than many other vegetable oils.

I don't know about costs, but we used to cook in lard, dripping and butter or even ghee. We could do that more.
