How to eat meat healthily
Eating too much meat is harmful to intelligence, which does not mean that a small amount of meat can also reduce IQ. At present, the Chinese Society of Nutrition only recommends eating 50-75 grams of meat (body weight) per day, which is 3-5 pieces (jujube-sized pieces) according to roasted beef. This amount did not find any harm. Its nutritional significance is to prevent iron deficiency anemia, especially for women and children of childbearing age.
Many people think that the advantage of vegetarian diet is that they don't eat fish, eggs and milk at all. This concept is wrong. The benefits of vegetarian diet lie not in "far away from fish, eggs and milk", but in the rational combination of a large number of natural plant foods such as vegetables, fruits, grains, beans, nuts and so on. Don't forget that fries, fries and twists are vegetarian. Biscuits and sweets can also be vegetarian. And these things don't improve intelligence.
03. Eat less meat, even vegetarian food, we must ensure adequate nutrition. Undernourished vegetarian diet may not improve intelligence. Undernourished vegetarian diets not only do not make people smart, but also cause anemia, protein deficiency, vitamin B12 deficiency and affect children's intelligence. There are many studies in developing countries. Studies in poverty-stricken areas and other developing countries have found that the learning ability of anemic children is significantly lower than that of non-anemic children, especially when nutritional deficiency occurs early in life, which has a greater impact on brain development. It can be said that children lose at the starting line.
Eating more vegetables, especially green leafy vegetables, may be more important than vegetarianism. Nutritional circles in China recommend that people eat a small amount of meat and fish, while eating a large number of vegetables. There is no contradiction between one or two meats a day and one kilo of vegetables a day. Vegetables supply vitamin C, carotene, folic acid, potassium, calcium, magnesium, dietary fiber and antioxidants, which play an important supporting role in good intelligence, and can also help prevent many chronic diseases such as cardiovascular and cerebrovascular diseases. A catty of vegetables a day, including half a catty of leafy greens, is essential to health.
