Would it really be healthier to skip staple foods? RZ.jpg
If it is a rumor, it is clearly written by a famous medical expert who has studied brain and nervous system diseases for many years; if it is said that doctors do not understand nutrition, the book clearly lists a large number of research evidence, which can not help but distrust readers.
A friend asked confusedly, "Is it because I have eaten pasta all my life? If I don't eat them, my brain will be better used?"
Another friend asked: What on earth should I eat if I don't eat staple food? Every day I eat big fish and big meat for dinner. I don't eat any staple food, let alone unhealthy. First of all, I can't eat it and I can't afford it.
To be honest, the contents of this book did not surprise me very much. Because I have read a lot of relevant research evidence, and very much agree with some of the statements - do not eat so much pasta, sweets do not eat, long-term hyperglycemia reaction is harmful.
There are enough studies to convince people that postprandial hyperglycemia is a factor that accelerates brain aging. The staple foods we eat, whether white rice, steamed bread, white bread, or yolk bread, steamed buns, rolls, jujube cake, corn cake, haircake, white rice porridge, rice cake, which are hyperglycemic reaction food. The study found that people with poor postprandial glycemic control scored lower on cognitive tests, and that the working ability of the brain decreased earlier in obese people than in people with normal weight. In addition to promoting brain aging, a hyperglycemic diet also increases the risk of obesity, diabetes, cardiovascular and cerebrovascular diseases and some cancers.
Gluten in wheat (often translated as gluten) is a common cause of chronic food allergies. Many people in Europe are chronically allergic to gluten, which may not only lead to obesity, but also lead to functional disorders of the brain nervous system such as brain blankness and confusion. It's not only found in white steamed bread, but also in whole wheat bread. It's also found in pasta and pasta with hypoglycemic reactions. Therefore, if a chronic allergy to wheat gluten is detected, you should stay away from all flour-containing foods, even the layer of flour wrapped in fried prawns is best avoided.
If, as the author advocates, people do not eat all kinds of staple foods and eat fish and vegetables, then they do have a rapid weight loss, which makes many people feel amazing, in fact, it is only a biochemical common sense - because doing so will not allow fat to fully decompose, producing energy-containing "ketone body". To acidify the blood, the body must expel it as soon as possible. But excreting ketones means that the body wastes a lot of energy, so the speed of fat decomposition is much faster than that of normal "hold your mouth, open your legs". At the same time, since starch and sugar are basically not eaten, postprandial blood sugar rises slightly. In a short period of time, this way of eating will become thinner, blood sugar will be reduced, blood lipid will not rise.
But don't hurry to cheer first. The diet without staple foods has been popular several times since the 1960s and 1970s, but every time it has changed from hot to weak, and I believe this time it will be no exception. Because there is no such perfect dietary health solution in the world. This is not about complex scientific research, but about common sense, which is easy to understand. Can we solve these problems if we don't eat food, potatoes and beans for a lifetime and mainly eat fish, eggs and vegetables?
1. Fish is the staple food and food safety is worrying.
Many Westerners believe in the "Stone Age Diet" and say that meat was the main food of ancient humans, and eating meat was the right life for human genes. However, fish as a staple food is more likely to cause environmental pollution than grains, legumes, vegetables and fruits. According to the law of biological amplification, the concentration of difficultly decomposed environmental pollutants (such as heavy metals, dioxins, polychlorinated biphenyls, hexachlorocyclohexane, etc.) will increase by at least 10 times with each increase of trophic level. Now is not the ancient environment without chemical pollution. Eating one or two meats a day is less likely to be contaminated, but eating one or two kilograms of meat a day is 10 times more likely to be contaminated.
Some people say that I can choose organic food and wild deep-sea fish. But can you guarantee that all the fish, meat and eggs you eat in your lifetime are organic? Even deep-sea fish can contain mercury pollution, so it's not wise to eat a lot.
Eating meat as a staple food will increase the risk of intestinal cancer and other cancers, as well as cardiovascular and cerebrovascular diseases.
As you can recall, the World Health Organization (WHO) last year listed red meat and meat processed products (sausage, ham, bacon, bacon, etc.) as a class of carcinogens, because too much red meat increases the risk of intestinal cancer. There are also many studies showing that too much red meat (more than 100 grams per day on average) and processed red meat (25 grams per day).
