In recent years, many people have developed the habit of eating more vegetables and less, which is euphemistically called: "Low-sugar food is nutritious and not easy to get fat."
According to the sugar content of food, it can be divided into three categories: high sugar, low sugar and no sugar.
Foods with high sugar content mainly include edible sugar and various grains; Sugar-free foods mainly include various edible oils; Low-sugar food mainly refers to vegetables, fruits and meat. The official name of low-sugar food is "low-carbon hydrate food", that is, eat more fat and protein and less carbohydrates in the diet, that is, eat more vegetables and eat less.
In view of this fashion, nutritionists in China have raised objections that low-sugar foods cannot be eaten as meals.
The reason for this is the following：
1 The human body's heat comes from food, and there are three nutrients in food that can produce heat: protein, fat and carbohydrate. According to the basic principles of nutrition, the proportion of calories in residents' daily diet is 10%- 15%, 20%-25% and 60%-70% respectively. If we adopt a low-sugar diet, which means eating more vegetables, eating less or not eating, then the heat source that our body needs is provided by protein and fat, which is contrary to scientific laws. Because the energy provided by carbohydrates is the most economical and main energy source for human body.
Get rid of dependence on an imperfect diet.
As a result of a low-sugar diet, the intake of livestock and fish rich in protein and fat will inevitably increase, and the intake of oil will also increase. Even frying vegetables with too much oil will inevitably lead to excessive accumulation of fat in the body, which will lead to obesity, hyperlipidemia, hypertension and coronary heart disease.
Low-sugar diet means eating less staple food, and the intake of carbohydrates is far from enough to meet human needs, which will lead to the lack of important substances in the body. For example, the decrease of glucose will affect the thinking activity of the brain. According to research, the brain needs about 130 grams of starch staple food every day to provide energy. If it is insufficient, it will cause listlessness, inattention, slow thinking and anxiety. B vitamins are closely related to carbohydrate metabolism. When they are deficient, there will be metabolic disorder, slow wound healing, decreased blood loss tolerance, fatigue, insomnia, loss of appetite and so on.
