At 3:00 in the afternoon, Ms. Zhao, who was a bit tired of work, took out a bag of “White Rabbit†toffee and kindly distributed it to his colleagues. However, he had attracted many objections. "Let's eat less sugar. Don't you be afraid of diabetes and high blood pressure in the future?" "I don't eat, I want to lose weight!"
With the improvement of people’s living standards, the incidence of diabetes, obesity and dental caries has also increased. As a result, many people have misunderstood that diabetes is the culprit of these diseases, and exaggeratedly called "white poison." Started a vigorous campaign to suppress sugar. In fact, for a healthy person, reasonable sugar can help health.
Safe and affordable source of energy
Qian Xuejun, professor of Beijing University of Traditional Chinese Medicine, said: "In sugars, fats and proteins, these three types of alternative energy sources can be used to burn sugar in different ways, whether under aerobic or anoxic conditions. In order to provide energy for humans, after the energy is burned in the body to release energy, the final products are carbon dioxide and water, and carbon dioxide can be easily eliminated through the respiratory function of the lungs, with almost no harm to the human body. In the process, harmful substances such as ammonia are produced, and fats produce ketone bodies during catabolism, which is harmful to the organism.
In addition, sugar is also a necessary substance for the human body. After sugar is digested and absorbed by the human body, it can easily be converted into blood glucose, or blood sugar. Blood glucose can smoothly pass through the barrier and become a source of energy for brain tissue under normal conditions. Because of the brain tissue almost no special dependence and sensitivity. Once blood sugar is not enough, it is easy to appear cloudy. Nervous, unresponsive, tired or even coma. on the contrary. Sugar can stimulate brain activity and improve function. This has been confirmed by researchers from MIT students in the United States.
There must be enough sugar in the blood to fully supply the energy needed for the cells. Research shows that when the sugar in food is consumed, people are prone to burnout. When blood sugar falls to 70 mg, people gradually feel hungry. Tiredness gradually developed from a sense of fatigue. When blood sugar continues to fall, fatigue will become exhausted, and dizziness, weakness, and instability will occur. It may even be abnormal heart rhythms, weak legs or vomiting.
Sugar and disease are not necessarily linked
Sugar is not the culprit in causing the disease. Professor Chen Junshi of the Institute of Nutrition and Food Hygiene at the Chinese Academy of Preventive Medicine pointed out: According to epidemiological studies, there is no direct relationship between sugar intake and the incidence of obesity. Fat intake is closely related to obesity. It does not matter how much sugar is eaten, because diabetes is caused by impaired islet function. There is also no direct relationship between sugar intake and elevated blood lipids. It should be said that the main dietary factor that affects lipid changes is saturated fatty acids. Sucrose or fructose intake is high when it is possible to cause elevated blood lipids. This is due to fructose in the liver. Due to the unique metabolic pathways, therefore, sugar does not cause elevated blood lipids under normal intake conditions.
Sugar is more than the beginning of the tooth decay. As we all know, the United Kingdom has always maintained a high per capita consumption of sugar, but the incidence of dental caries is low. In contrast, the incidence of dental caries is high in China, where the consumption of candies is low in food stores. Professor Chen said: “People think that eating sugar easily leads to dental caries, because sugar exists in the cavity for a long time and can become a bacterial culture medium that causes tooth decay. If sugar is used, use a mouthwash or other methods to remove the mouth in time. The sugar does not cause dental caries."
Chinese people should eat sugar properly
Jia Zhiren, president of the China Sugar Association, said that Chinese people consume only 8 kg of sugar per year, which means that the average daily consumption is only 21.9 grams. The annual average sugar consumption of Americans is as high as 70 kilograms, and the average daily consumption is 192 grams, which is a far cry from the two. According to another survey, the per capita sugar consumption in China ranks the 7th lowest in the world. It is a very low level. Because of this, when the Chinese Nutrition Society revised the Dietary Guidelines for Chinese Residents in April 1997, it deleted the article “Sweet foods to eat less.†There was no emphasis on controlling the intake of sugar.
In fact, the body needs a lot of nutrients, any food or essential nutrient intake will cause malnutrition. The long-term consumption of sugar in large quantities exceeds the needs of the human body and the liver's ability to handle it. It can also cause certain harm to the body. Therefore, we should learn to eat sugar scientifically and reasonably. Nutritionists recommend 30-40 grams of sucrose per day. Older people, due to physical adjustment control intake. For people with diabetes, obesity, low glucose tolerance, hypercholesterolemia and coronary heart disease who are not suitable for sugar, they must be able to eat sugar in the right amount under the guidance of nutritionists.
