There are five different sources of evolutionary evidence that indicates the path to the optimal human diet.
Dr. Paul Jamine – astrophysicist and author of “Diet for perfect health”. He and his wife Shou-Ching, a scholar-biomedic from Harvard, collaborated in the creation of an improved approach to the Paleolithic diet, which I believe can be quite valuable. As is often the case with innovative results in health, and their joint search of the optimal diet were due to chronic health problems. Dr. Jamine experienced symptoms similar to the symptoms of multiple sclerosis, cognitive decline, neuropathic problems, and rosacea. These symptoms initially appeared around 1992, after a long course of antibiotics. Meanwhile, his wife had endometriosis, fibroids, hypothyroidism and other problems. She ate a lot of soy, which apparently was a major factor.
To create the perfect diet, it would take thousands of lifetimes to read all medical literature
Dr. Jamine also raised an important point as it concerns detective work related to the definition of what may be the ideal diet, it is the elucidation of the full picture, as close to the truth. Because without this information it is almost impossible to correctly interpret some scientific results.
“PubMed, a database of journal articles, contains more than 22 million articles, and each year added more than a million. Think of how many people can read, I read not more than two articles a day … Maybe I read 500 articles in a year. So when in the year out of a million, and it is possible to read only 500, maybe 1000, you can see only a small part of the literature.
Very easy to have a kind of selection bias; to get a small amount of information from the literature and to draw the wrong conclusions. Biology is a complex science. Articles in journals are difficult to interpret. Usually, there are many different ways to interpret any single article. You need a big, comprehensive picture, which is very close to the truth so you know how to interpret each article.
I found that if you start with an evolutionary perspective, it leads you very close to the truth. In fact, there are five different sources of evolutionary evidence, and they all point in the same direction on what constitutes an optimal diet for humans! And when you start with this perspective and interpret the article in this light, it is much easier to perceive the information in different articles.
… Now, when I look how other people interpretiruya literature, I usually see that it is highly dependent on their knowledge of their specialty, and they usually do not take into account evidence from other specialties … Experts know a lot. But they have a limited perspective that can easily fool them regarding diet.”
I agree that one of the major factors ignored by so many “health authorities”, there is a perspective from the point of view of the big picture – the evolutionary perspective of the human body and the food that feeds him. And this perspective is truly key, as it provides a solid starting point from which to evaluate all subsequent.
To understand what we are doing wrong, we need to assess how our modern diets differ from the diets of our ancestors. The answer are not new and improved chemicals to replace the nutrients. The answer lies in what a person is supposed to eat by nature…
So Dr. Jamine decided to try the “Paleo diet” because it had the strong evolutionary support and could significantly limit the review of the literature. But as he began to experience some negative effects during the first year, he came to the conclusion that the Paleo diet still had some weaknesses and flaws that he decided to fix it.
“That’s where the handy fact that my wife works at Harvard, he says. – We have access to all medical journals I have access to her experience, as well as a broader look at nutrition in Asia … the more we learn about diet the more we learn that traditional Asian diets [and traditional dishes in General] are actually very healthy. This gave us confidence that we are on the right track.”
Five sources of evolutionary evidence offer compelling clues for finding the optimal diet
The Paleo diet is based on what our ancestors ate in the Paleolithic period. There were no supermarkets, so they hunted and gathered food. It also tells about whatwas westvaal regional variability in the diet of the people since they could eat only what grew and was available in their climate.
“Eskimos (Inuit) ate a diet composed almost entirely of animal products … People in the tropics consume more carbohydrates. But, as a rule, the amount of carbohydrates eaten was … from 15 to 20 percent. We learned that the tribes of hunter-gatherers, with whom he established contact in the 1800s. We have accurate information about that period that looked like the diet of hunter-gatherer.”
The second source of evidence is the composition of breast milk of a person, which we can assume should be in the context of evolution, the ideal form of nutrition for infants from the point of view of nutritional value. And, although the nutritional needs of children differ from adults, we can appreciate how they differ, and adjust them accordingly.
“Babies have a very large brain compared to body size, so they use a lot of glucose,” says Dr. Jamine.” Approximately 50 percent of the calories that they use glucose. In breast milk contains about 40 percent carbohydrates. Thus, the amount of carbohydrate in the diet is a little less than the amount that child will really use.
If you transfer these data to adults, they use about 30 percent of their calories as glucose. We predict, based on the composition of breast milk that the optimal amount of carbohydrates for an adult is just below 30 percent, so maybe 20 to 30 percent. This is another example.”
Thirdly, we can look at the diets of other mammals.
“They feed on the optimal human diet, because animals are biologically similar to us but have the brain of a smaller size. Thus, as infants are similar to adults, but have a larger brain [relative to body size], animals have smaller brain [in General], and most of the animals … eat very low carb, often their diet consists of carbs by 5 or 10 percent.
People think that different animals eat different, because there are herbivorous, carnivorous, omnivorous. They do eat different food, but the food transformirovalsya in the intestine and in the liver. What varies in different animals, the evolution is not the body and its nutrient requirements is a condition of the intestines and liver.
Thus, herbivores often have the intestines (e.g., ruminants), which converts carbohydrates into fats and volatile acids. A cow, for example, has almost no carbohydrates in your diet. All carbohydrates are absorbed by the bacteria that produce short chain fats …
Considering these animals as an example, we get more evidence, should look like an optimal diet. This, again, leads us (when we make allowances for the size of the brain) to the diet with 20% carbohydrate for adults.”
Fourth, the evolutionary evidence include an innate ability to survive the long fasting or starvation in times of shortage. The human body was designed in order to effectively hunt or gather food even on an empty stomach. This means that the human body needs to be able to “absorb” yourself.
“You must effectively survive on the composition of the human body. The optimal diet for humans can’t be far from the nutrient composition of the human body itself,” explains Dr. Jamini.
And last but not least, the fifth source of evolutionary evidence is the system of remuneration for the power of the human brain.
“We like certain types of products. We like to get a certain amount of protein every day. We like to get a certain amount of salt every day. Some things are pleasant to the taste, some things are very unpleasant. These taste and nutritional preferences evolved so we could eat healthily. We can deduce from these innate preferences of the brain, what is a healthy diet,” says Dr. Jamine.
“These five sources of evidence we largely used to find out what is the optimal diet. And as soon as we received this starting point, we went to the literature to find the evidence and reached the level of nutrients and toxins to try to figure out how to implement it from the point of view of food and how really to optimize.”
Optimal diet also should limit food toxins
Another important aspect is the toxins – not only the artificial toxins and toxic pollutants, and the natural toxins contained in various products. For example, unfermented soy is known for its toxic potential.
“One of the strengths of the paleo diet is that it has a very low level of toxicity, says Dr. Jamine. – This occurs for several reasons: first, the products usually are recommended in this diet have a low toxicity. One of my favorite articles is the conclusion that if you eat one gram of wheat bran, the weight of your feces will increase by more than 5 grams. This tells us that the wheat are biologically active proteins that are sabotaging digestive function. Thus, they not only prevent the digestion of wheat bran, and other foods you eat with them. That is why the weight of feces so is greatly increased.
The problem is that if they can disrupt the body, like digestion, they can also disrupt other functions. These toxins can actually have a negative impact on health. There is increasing evidence that the impact is very significant.
Another really interesting study conducted in Japan this summer. Children in Japan who every day eat wheat … get almost four points less in IQ tests than children who eat rice. The rice is good (it’s the only grain that we recommend in your diet), that the toxins are destroyed during cooking. Cooked white rice, minimal amount of toxins.
This gives us an idea of how wheat can affect our health. Interestingly, the difference in coefficent IQ Asians and Americans is about four points. It could just be the difference between the consumption of wheat and rice.”
Dr. Gamini explains that the rice, which is starch, consists of long chains of glucose and virtually no fructose, which is good. Ideally you need to avoid as many of fructose, particularly in the form of corn syrup with high fructose, which is in almost all processed foods and beverages.
When consumed in excessive amounts, fructose is becoming quite toxic, and excessive consumption of fructose is the main driving force for the rapid growth of obesity and chronic diseases.
“Have fructose only from fruits, berries and vegetables, says Dr. Jamine. – There are some sweet vegetables, which are useful, for example, zucchini, carrots, onions and beets. In General, fruits and berries are useful. They give you fructose, but in small quantities.”published econet.ru.
