What are the effects of meat on human health?

In recent years, there are more and more negative reports about meat. First, there have been incidents of foot-and-mouth disease, mad cow disease and bird flu in food safety. Then in nutrition, the report that eating red meat every day is easy to get intestinal cancer appeared in major newspapers, and nutritionists always warned that "China people eat too much meat".

A study published by American scientists shows that the habit of eating meat has a great influence on the evolution of human body. It enhances people's ability to deal with fat and cholesterol in food, and changes people's tooth structure and body shape. More interestingly, it makes people evolve towards eating soft mushy food.

Research shows that the love of juicy steak has changed the body structure of generations. For example, people's mouths become smaller because of eating meat. When humans began to eat meat, a series of genetic changes took place in their bodies.

Meat is an important protein and energy source in our daily diet, and its nutritional value and edible value are extraordinary. From the point of view of nutrition, meat is a good source of amino acids, vitamins and minerals.

The research results of American scientists tell people that eating meat has a great influence on the evolution of human body, so don't abandon meat blindly regardless of physical conditions.

Meat food can provide people with quite a lot of protein. Animal protein belongs to high-quality protein, because the content and proportion of its eight amino acids are very close to the needs of human body, and its absorption and utilization rate is high.

Meat food can provide 60~70 grams of essential fat for human body every day, while the same amount of fat needs 5 kilograms of plant food to obtain. Meat can provide all minerals except calcium and is the best source in this respect.

Nutritionists point out that eating meat should follow a very important principle: livestock meat is not as good as poultry meat, and poultry meat is not as good as fish meat. For all kinds of meat, although the fat content of geese and ducks is not less than that of livestock meat (pigs, cows, sheep, etc.). ), their chemical structure is close to olive oil, which is not only harmless but also beneficial to the heart. Chicken is the best source of protein, rabbit can beautify and lose weight, and fish can nourish the brain and protect the heart, so it is a good meat product.

According to reasonable dietary standards, each person needs an average of 44 ~ 45g of animal protein every day. These protein are not only taken from meat, but also supplemented by milk and eggs. Therefore, it is best to eat meat dishes once a day, and it is best to eat them at lunch. The amount of meat is about 200 grams. In addition, adding some eggs and milk at breakfast or dinner can completely meet the human body's demand for animal protein in one day.

By the way, I'll give you a hint: eat a little garlic when eating meat. This is because although animal meat, especially lean meat, is rich in vitamin B 1, vitamin B 1 stays in the body for a short time and will be excreted with a small amount of urine. Eat some garlic while eating meat. Vitamin B 1 in meat can be combined with allicin in garlic, which increases the content of vitamin B 1 by 4~6 times, and makes the water solubility of vitamin B 1 become fat-soluble, thus prolonging the residence time of vitamin B 1 in human body.
