Japanese experts pointed out that eating more sugar will cause three major hazards to children, the first is fracture, the second is scoliosis, the third is dental caries, and cancer. Did you believe it when you heard about cancer? Maybe everyone will ask: How can sugar be related to cancer? Japanese researchers found that the calcium content in the blood of adults with gastric cancer and cervical cancer decreased significantly. Later, experiments were carried out with mice, and a group of mice were fed enough calcium and transplanted with cancer cells, but the results were unsuccessful. Transplantation of cancer cells into another group of mice with insufficient calcium supply is easy to succeed. This proves that cancer is closely related to calcium deficiency. Sugar can lead to calcium deficiency, which is considered as one of the inducing factors of some cancers. In addition, sugar not only lacks vitamins and inorganic salts, but also ruthlessly consumes inorganic salts and B vitamins, which undoubtedly weakens the body's anti-cancer ability. Sugar will also have a direct harmful effect on the body's immune system, which will reduce the phagocytosis of white blood cells and make it difficult for the body to destroy cancer cells. A British scholar has specially studied the harm of sugar. In Sugar and Harm, he not only studied the effects of sugar on obesity and heart disease, but also thought that sugar had a catalytic effect on cancer. Therefore, when eating, avoid excessive consumption. It is difficult to eat sugar scientifically and enjoy health. It's hard to completely refuse to eat sugar. So how much sugar should people eat in their daily lives, and what kind of sugar is healthier? The concept of not more than 40 grams of "sugar" per day has broad and narrow meanings. Sugar in a broad sense refers to various digestible carbohydrates, including sweet sugar and starch without sweetness; Sugar in a narrow sense refers to refined white sugar and syrup commonly used in food and beverage processing. The harm of sugar to human body is mainly the latter. Almost all sweets contain a lot of sweeteners made of white sugar or syrup. Therefore, it is very common for some children and young women who like to eat desserts, biscuits, snacks and drinks to consume more than100g of sugar every day. However, the daily intake recommended by nutritionists is about 30 to 40 grams, which should not exceed 10% of the total daily intake of carbohydrates. Eating too much polysaccharide is harmful. The purity of refined sugar is very high, which can reach more than 99%, that is to say, it contains almost no other nutrients and only a lot of energy. If you eat too much sweets, you will feel full, because too much energy will affect the intake of other foods rich in protein, vitamins, minerals and dietary fiber. In the long run, it will lead to diseases such as nutritional deficiency, developmental disorder and obesity. On the other hand, the metabolism of sugar in the body needs to consume a variety of vitamins and minerals. Therefore, eating sugar often will cause nutritional problems such as vitamin deficiency, calcium deficiency and potassium deficiency. Nutrition survey also found that although eating sugar may not directly lead to diabetes, long-term consumption of sweets will lead to excessive insulin secretion, disorder of carbohydrate and fat metabolism, resulting in imbalance of human internal environment, which will further promote the occurrence of various chronic diseases, such as cardiovascular and cerebrovascular diseases, diabetes, obesity, senile cataracts, dental caries, myopia, rickets and so on. Eating more sweets will also make human blood tend to be acidic, which is not conducive to blood circulation and weakens the defense function of the immune system. Sweetness is more harmful than smoking, and may also cause physical and psychological dependence. According to research, sweetness is the first taste accepted and pursued by human beings after birth, and liking sweets is an instinctive reaction of human beings. Medical experiments have proved that, in a sense, candy containing a lot of white sugar has the same effect on the brain as drugs. If animals habitually eat sweets, it will stimulate the brain to produce opioids and make them feel happy. Once the supply of candy is stopped, they will feel pain and fidgety, and the chemicals in their brains will be out of balance. When to eat sugar Although it is harmful to eat sweets in large quantities, it is also beneficial to health if you eat them in small quantities and at the right time. For example, when the blood sugar concentration decreases, eating a small amount of sugar can be urgently supplemented. Patients with hypoglycemia will feel black eyes and weak limbs when they are hungry. The best way is to drink a glass of sugar water at once. People who don't eat breakfast well often feel groggy, inattentive and have poor thinking ability near noon. At this time, if they eat sweets, they can quickly restore brain function. In addition, sports medicine research has confirmed that athletes can improve their sports performance if they supplement a small amount of sugary drinks before strenuous exercise; Supplementing sugar in time after exercise can eliminate fatigue. It is also beneficial for ordinary people to eat a small amount of sugar before taking a bath, when they are hungry and when they need to pay attention. You can choose what sugar to eat when you eat red pond. In order to find a balance between sweets and health, it is best to eat the following kinds of sugar: red pond, also known as "brown sugar" and "brown sugar", contains more minerals such as iron, calcium, potassium and magnesium, and has high nutritional value, which is beneficial to the acid-base balance in human body. Traditional Chinese medicine believes that Tang Hong has the functions of promoting blood circulation, removing blood stasis, warming middle warmer and dispelling cold. But the red pond is warm, so people who often get angry and thirsty should eat less. Oligosaccharides refer to fructooligosaccharides, lactose oligosaccharides and isomaltooligosaccharides. They are low in calories and have the function of "regulating ecological balance". Some of them are called "bifidus factors", which can promote the growth of beneficial bacteria in the body and inhibit the reproduction of intestinal pathogenic bacteria and spoilage bacteria. The sweetness of sugar alcohol sweeteners such as xylitol, sorbitol, mannitol and maltitol is slightly lower than that of white sugar. They are low in energy and blood sugar, do not cause dental caries and do not raise blood sugar, and belong to healthy sweeteners. However, the daily consumption should not exceed 20g, because they will promote intestinal peristalsis, and excessive consumption will cause mild diarrhea. Normal people eat too much sugar, and their teeth will bleed. White sugar will be metabolized in the body, sucrose will become monosaccharide, and monosaccharide will become glucose. This process will consume vitamin C in the body. If vitamin C is less, teeth will bleed. Moreover, the anger of white sugar is easy to cause fat growth. If you really want to add it, add rock sugar. White sugar is the crystallization of sucrose, and its purity is generally above 99.8%. From a chemical point of view, this is. White sugar has the pure sweetness of sucrose, which can not only be eaten directly, but also is the main variety of industrial sugar.
