eat less and eat more
——Actually, it’s unhealthy
On the dinner table, we often hear many people say: eat less and eat more dishes. There is no nutrition in the meal. Nutrition is in the dishes. On the surface, this seems reasonable. However, from the perspective of scientific nutrition, if it continues for a long time, it will be extremely harmful to health.
The main components of rice and pasta are carbohydrates, which are both economical and can be directly converted into calories. Since ancient times, we Chinese people have always regarded rice and pasta as essential food. The dietary physiological habits and nutrient absorption laws of a nation have been formed through the evolution of life for tens of thousands of years. Carbohydrates contained in cereals are also the main source of B vitamins in addition to providing energy for the human body. One obvious harm of the change in the status of staple foods is that it is easy to lead to the lack of vitamin B1.
In terms of the physical structure of the human body, carbohydrates are the main “basic raw materials” required by our body. From the point of view of decontamination, in a reasonable diet, 50% to 60% of the total heat energy required by a person in a day comes from carbohydrates, and compared with the large fish and meat in the dish, the staple food is much easier to digest. Why can’t we get tired of eating rice noodles every day, but eating big fish and meat for three consecutive days will turn us off? This is because big fish is big, meat tastes heavy, color heavy, and heavy oil. If you eat too much, it will cause a great burden to the intestines and stomach, and the intestines and stomach will have a great aversion and irritation.
Some people think that eating more vegetables is not a bad thing, but vegetables “eat” oil. Many vegetables are fried with a lot of oil, and some vegetables are like soaking in oil. If you eat like this, you will be prone to high blood pressure, cardiovascular disease and obesity.
Nutritionists also do not agree with the absolute view of “eating more and eating less”, but advocate a scientific and reasonable combination of staple food and non-staple food.
