Reasonable eating sugar

Eating sugar is not only a condiment for food, but also brings pleasant and beautiful taste to people. Sugar is one of the necessities of people's daily life and one of the sources of human nutrition.

Sucrose is the main ingredient of sugar. It is made of semi -reduced hydroxyl groups of one molecule glucose and semi -reduced aldo hydroxyl groups of one molecular fructose. The sucrose has a sweet taste, no odor, easy to dissolve in water and glycerin, slightly soluble in alcohol. Sucrose is almost common in the leaves, flowers, stems, seeds and fruits of the plant world. The content of sugarcane, beet and cricket juice is particularly rich.

After people consume sucrose, after digestion, it is decomposed into monosaccharides (glucose and fructose) by the human body, producing heat energy, and maintaining physiological functions. The product of sucrose breakdown is carbon dioxide and water, which is easy to discharge from the body.

The consultation report of the "Carbohydrates in Human Food" jointly published by the United Nations Food and Agriculture Organization and the World Health Organization pointed out that many years of research has refuted various misunderstandings and provided consistent evidence that daily sugar is a safe and valuable food. source.

According to statistics from global sugar usage and obesity rate, the average sugar usage and obesity rate have no obvious linear association. No exact evidence indicates that the sweetness of sugar leads to an increase in appetite.

The human body usually has a stronger appetite to reduce its appetite -rich foods rich in carbohydrates and sugar foods. Excessive energy intake of any form of energy will lead to obesity, and maintaining energy balance is the key to preventing obesity.

The formation of dental caries is a more complicated process, which is related to food types, eating frequency, oral cleanliness (staying in the mouth in the mouth), the acquisition of fluoride, the function of saliva, and genetic factors. Sucrose and starchy foods can affect the onset of dental caries, but the impact of various types of food on the incidence of dental caries is difficult. Studies have shown that the impact of high sugar content in food on dental caries is not as good as the stay time of these food residues in the oral cavity on dental caries. Therefore, it is more effective to reduce the incidence of dental caries by reducing the intake of a certain food to reduce the incidence of dental caries.

Carbohydrates are the main sources of energy needed for people to maintain their lives, and provide the brain to provide a steady stream of energy to maintain the normal development and operation of the brain.

Carbohydrates are the main sources of human activity energy. They store the human liver and muscles in the form of glycogen, and the body needs glycogen during sports activities. If the glycogen storage in the body becomes less, people will feel fatigue and lead to a decline in exercise results. Therefore, before exercise, it is guaranteed to have sufficient glycogen storage in the body. During the exercise, carbohydrates need to be replenished in time. After or after exercise, it is necessary to supplement the glycogen storage, which is conducive to improving exercise results.

Carbohydrates and other carbohydrates are also crucial for brain workers. Because carbohydrates can maintain the normal function of the brain cells, glucose is a necessary nutrient for maintaining the normal function of the brain. After the human body is digested, it is easy to transform into glucose (ie blood glucose) in the blood. Because the brain tissue has almost no glycogen reserves, it has special dependence and sensitivity to blood sugar. 2/3 of the total blood sugar (about 111-145 grams per day) is required for brain tissue, and brain tissue is the most sensitive to sugar deficiency and hypoxia. Insufficient blood glucose, it is easy to cause tiredness and even coma. Proper sugar supplementation is conducive to improving brain function. (Edit Li Chuang)
