Complementing shape with shape, which is what we often say, is also a widely spread concept in dietotherapy theory. But is there really a scientific basis for "what you eat to supplement what you eat"?

First of all, don't listen to the so-called shape-filling. The effect of food on human body depends not on its shape, but on its main components.

Human growth, development and life-sustaining function need 40-50 kinds of nutrients, mainly including carbohydrates, protein, fat, water, minerals, vitamins and cellulose.

Any food contains these nutrients more or less, but in different proportions. For example, meat contains more protein and fat, while fruits and vegetables contain more vitamins and cellulose.

However, all foods need to be digested, absorbed, biotransformed and transported, so that various nutrients can be transported to various tissues and organs of the whole body through blood circulation.

And food will be decomposed into various nutrients after being eaten by people. Food can't be mended, and shape can't be mended. There is no biochemical mechanism to support the idea that you can supplement what you eat.

In addition, some unreliable dietary proverbs are widely circulated.

1, unclean, eating is not sick.

There is no scientific basis for eating unclean food and not getting sick. As the old saying goes, food does not need to be sterile, and there is no need to emphasize clean food in particular. Some people think that proper and unclean food can often improve patients' resistance.

But this is not the case. Food contaminated by microorganisms and microbial metabolites will lead to intestinal inflammation in patients. Most intestinal diseases are related to microbial infection, including acute enteritis and chronic enteritis. Some patients may develop inflammatory bowel disease, but some people think that inflammatory bowel disease infection is only the inducing factor. Therefore, there is no scientific basis for eating unclean food. Unclean food is likely to cause diseases, which may lead to acute inflammation, and some patients may become chronic inflammation.

2、? Eat crabs raw and shrimps alive.

Eating raw seafood has become the current food fashion, but eating raw seafood is not good for your health. All kinds of live fish, shrimps and crabs often hide all kinds of pathogenic bacteria, which are difficult to find with the naked eye. Eating half-baked contaminated fish and shrimp often leads to gastrointestinal discomfort, insensitivity, neurasthenia, hypotension and other poisoning symptoms. Some people like to eat live shrimp and fresh crabs after salting and soaking in wine, which is not safe.

3, eat radish in winter and ginger in summer, without a doctor's prescription.

Radish has no magical effect. If you compare the nutritional components, radish is usually a "defeated soldier" and can only provide a small amount of vitamins, minerals and dietary fiber. Not to mention such exaggerated statements as "radish participates in ginseng" and "radish cures all diseases".

Regarding the saying that "eat ginger in summer", ginger contains many active ingredients, including volatile oil, gingerol, diphenyl heptane, etc., which can stimulate appetite. But in fact, all kinds of spices can promote appetite, but ginger can't.

4, a cold to eat, a fever to be hungry.

This is a common misunderstanding of the immune system all over the world. At present, scientific research has not found the scientific basis that fasting can reduce fever body temperature. When you have a fever, it is also a kind of consumption to the human body. You must not be hungry at this time. You must give normal nutrition intake and ensure nutrition supply.
