A few nice diabetes diet images I found:

As if we didn’t have enough reason to be upset with corn, now I learn about the omega-6 / omega-3 ratio, and its role in inflammation and disease.

I just spent the past couple days with Craig Venter and his companies: Agradis, Synthetic Genomics, and SGVI. The chart above and quotes below are from Artemis Simopoulos’ visit from The Center for Genetics, Nutrition and Health in Washington, DC.

In short, human genetics are optimized for a prehistoric diet where the omega-6/3 ratio was about 1:1. It’s now 17:1, and it’s killing us.

We get way too much omega-6 from grains (corn, wheat, margarine) and way too little omega-3 (fish oil, butter, algae). We even feed corn to the farmed fish now, so many salmon steaks are devoid of omega-3’s and may be as unhealthy as beef steaks. The 3 and 6 fatty acids are similar, but very different to our health, much like good and bad cholesterol.

On the graph above, the Vitamin C and E lines correspond with the right Y-axis, and all of the others are fat proportions of our diet (on the left Y-axis). While major diet changes occurred during the agricultural revolution, it was much more recently that the omega-6/3 ratio went out of whack.

Here are some summary quotes from the recent paper in Experimental Biology and Medicine:

“Whereas major changes have taken place in our diet over the past 10,000 years since the beginning of the Agricultural Revolution, our genes have not changed. The spontaneous mutation rate for nuclear DNA is estimated at 0.5% per million years. Therefore, over the past 10,000 years there has been time for very little change in our genes, perhaps 0.005%. In fact, our genes today are very similar to the genes of our ancestors during the Paleolithic period 40,000 years ago, at which time our genetic profile was established. Humans today live in a nutritional environment that differs from that for which our genetic constitution was selected.

A lower ratio of omega-6/omega-3 fatty acids is more desirable in reducing the risk of many of the chronic diseases of high prevalence in Western societies, as well as in the developing countries.

human beings evolved on a diet with a ratio of omega-6/3 of ~1, whereas in Western diets the ratio is ~17/1.

Western diets are deficient in omega-3 fatty acids, and have excessive amounts of omega-6 fatty acids compared with the diet on which human beings evolved and their genetic patterns were established. Excessive amounts of omega-6 and a very high omega-6/3 ratio, as is found in today’s Western diets, promote the pathogenesis of many diseases, including cardiovascular disease, cancer, and inflammatory and autoimmune diseases, whereas increased levels of omega-3 (a lower omega-6/3 ratio), exert suppressive effects. In the secondary prevention of cardiovascular disease, a ratio of 4/1 was associated with a 70% decrease in total mortality. A ratio of 2.5/1 reduced rectal cell proliferation in patients with colorectal cancer… The lower omega-6/3 ratio in women with breast cancer was associated with decreased risk. A ratio of 2–3/1 suppressed inflammation in patients with rheumatoid arthritis, and a ratio of 5/1 had a beneficial effect on patients with asthma, whereas a ratio of 10/1 had adverse consequences.

Genetic factors determine susceptibility to disease and environmental factors deter- mine which genetically susceptible individuals will be affected. Nutrition is an environmental factor of major importance.

The rapid changes in our diet, particularly the last 150 years, are potent promoters of chronic diseases such as atherosclerosis, essential hyper- tension, obesity, diabetes, arthritis and other autoimmune diseases, and many cancers, especially cancer of the breast, colon, and prostate.

Food technology and agribusiness provided the economic stimulus that dominated the changes in the food supply.

Before the 1940s cod-liver oil was ingested mainly by children as a source of vitamin A and vitamin D with the usual dose being a teaspoon. Once these vitamins were synthesized, consumption of cod-liver oil was drastically decreased, contributing further to the decrease of omega-3 intake.

A balance existed between omega-6 and omega-3 for millions of years during the long evolutionary history of the genus Homo, and genetic changes occurred partly in response to these dietary influences. During evolution, omega-3 fatty acids were found in all foods consumed: meat, wild plants, eggs, fish, nuts and berries. However, rapid dietary changes over short periods of time as have occurred over the past 100–150 years is a totally new phenomenon in human evolution.

Omega-6 and omega-3 fatty acids are essential because humans, like all mammals, cannot make them and must obtain them in their diet.

Mammalian cells cannot convert omega-6 to omega-3 fatty acids because they lack the converting enzyme, omega-3 desaturase.

Both omega-6 and omega-3 fatty acids influence gene expression. Omega-3s have the most potent anti- inflammatory effects. Inflammation is at the base of many chronic diseases, including coronary heart disease, diabetes, arthritis, cancer, osteoporosis, mental health, dry eye disease and age-related macular degeneration.”

The Flower of Bitter gourd..
The bitter gourd has excellent medicinal virtues. It is antidotal, antipyretic tonic, appetizing, stomachic, antibilious and laxative. The bitter gourd is also used in native medicines of Asia and Africa.

The bitter gourd is specifically used as a folk medicine for diabetes. Recent researches have established that it contains a hypoglycaemic or insulin-like principle, designated as ‘plant-insulin’, which has been found highly beneficial in lowering the blood and urine sugar levels. It should, therefore, be included liberally in the diet of the diabetic. For better results, the diabetic should take the juice of about four or five fruits every morning on an empty stomach. The seeds of bitter gourd can be added to food in the powdered form. Diabetics can also use bitter gourd in the form of decoction by boiling the pieces in water or in the form of dry powder.
