At the dinner table, many people often say, "Eat less and eat more vegetables. Rice has no nutrition, but nutrition is in vegetables. " There are also some women who pay too much attention to their figure and regard it as a "wise saying" to lose weight. On the surface, this seems very reasonable, however, from the perspective of scientific nutrition, if this continues for a long time, it will be extremely unfavorable to health.

The main components of rice and pasta are carbohydrates, which are relatively economical and can be directly converted into calorie nutrition. We in China have always regarded rice and pasta as essential foods since ancient times. A nation's dietary physiological habits and the law of nutrient absorption cannot be easily changed in one or two generations, but it takes tens of thousands of years of life evolution to form.

According to the material structure of human body, 99% of human body and its organs are composed of water, and carbohydrates are the main basic raw materials needed by our body. From the point of view of gastroenterology, in a reasonable diet, 50% to 60% of the total heat energy needed by people in a day comes from carbohydrates. Compared with the big fish and meat in the dish, rice is much easier to digest, and it has the irreplaceable necessity of other nutrients. The staple food is generally tasteless, except for the faint aroma of rice. Why do we never get tired of eating rice all our lives, but eating big fish and meat for three days in a row will make us sick? This is because the taste of big fish and big meat is heavy, and if you eat too much heavy oil, it will cause great disgust and * * * feeling in your stomach. Too much or too much intake of rich dishes will cause a great burden on the stomach.

Eating vegetables with high protein, high fat and low fiber for a long time is very harmful to health. Some people think that eating more vegetables is not a bad thing, but vegetables are "eaten" by oil. Many vegetables are fried with too much cooking oil, and some vegetables are just like soaking in oil. If you eat like this, you will easily get high blood pressure, cardiovascular disease and obesity.

Nutritionists also disapprove of the absolute view of "eating less vegetables". Advocate the scientific and reasonable collocation of staple food and non-staple food. Rice, vegetables, meat dishes, fruits and, of course, staple foods should account for an absolute proportion. In addition, it depends on everyone's growth stage. Teenagers are growing their bodies, bones and activities. The ratio of staple food to non-staple food has its age characteristics. However, the proportion of staple food and non-staple food for the elderly is different from that of teenagers.
