Is it better to eat more or less vegetables?

Answer: At the dinner table, parents often told their children to eat more and eat less vegetables. With the improvement of people's living standards in our country, parents now often ask their children. It doesn't matter if they eat less, as long as they eat more vegetables. Children often eat eggs and milk for breakfast, which parents think is very nutritious. According to statistics, the daily food consumption of Shanghai residents is only 100 grams, which is more than 2 ounces. This is very unscientific and harmful to human health. As we all know, carbohydrates mainly exist in grains.

First of all, carbohydrates are the most economical and main energy source for human beings. Except for babies under 2 years old, 55% ~ 65% of the daily energy needed by human beings should be supplied by carbohydrates. It is not only the most effective energy for human muscle activity, but also the only energy source for important tissues and cells such as brain, heart, red blood cells and white blood cells. At the same time, it is also a clean energy source for the body, and its final metabolites are carbon dioxide and water. Just like the car that uses hydrogen as energy now. Therefore, if students don't eat some food for breakfast, they will not be able to meet the energy demand of brain activity in the morning, which will easily lead to drowsiness, inattention and memory loss.

Secondly, carbohydrates are also important substances that constitute body tissues and participate in cell composition and various metabolic activities. At the same time, the metabolism of fat in the body needs the participation of carbohydrates, otherwise too many ketone bodies will be accumulated in the body, causing ketonemia. In addition, there are many other functions, such as saving protein, detoxifying during the metabolism of harmful substances, enhancing the intestinal function, and improving the taste and satiety of food.

Therefore, the Nutrition Society of China suggested that the daily intake of cereals (including miscellaneous grains) for the general population should be between 300g and 500g.
