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 total amount of sugar recommended by nutritionists is about 30-40 grams per day, that is, it should not exceed 10% of the total daily carbohydrate intake. What is the concept of 30-40 grams of sugar? Among the sweets that people often eat, the sugar content of a spoonful of jam is about 15g, that of 1 can of cola is about 37g, that of three small pieces of chocolate is about 9g, that of 1 can of ice cream is about 10g, and that of several biscuits is about10g.
NO. 1 eating too much sugar will lead to a very high purity of refined white sugar after crushing, which can reach over 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. NO.2 eating too much sugar will cause nutrient loss. The metabolism of sugar in the body needs to consume a variety of vitamins and minerals. Therefore, eating sugar often will cause nutrient loss problems such as vitamin deficiency, calcium deficiency and potassium deficiency. NO.3 eating too much sugar is good for blood circulation. Nutrition survey also found that although eating sugar may not directly lead to diabetes, eating sweets for a long time 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. NO.4 Eating sugar and taking drugs in Otawa have the same physiological reaction, and the craving for sweets 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. This phenomenon is very similar to the reaction of drug addiction. NO.5 eating too much sugar can cause mild diarrhea, but the daily consumption is best not to exceed 20 grams, because they will promote intestinal peristalsis, and excessive consumption will cause mild diarrhea. NO.6 eating too much sugar can lead to liver disease. The results of animal experiments published by German researchers at the annual meeting of the American Society of Hepatology in Boston, USA, show that eating too much sugar can damage the human liver and cause liver disease. NO.7 eating too much sugar leads to dental caries, and the prevalence rate among children in China has reached 70-80%. The main reason is that eating too much sugar provides good breeding conditions for oral bacteria and gradually melts the enamel on the tooth surface. Because sugar is an acidic food, it will corrode teeth and form dental caries. NO.8 eating too much sugar leads to decreased vision. Eating too much sugar will do harm to the eyes in two ways because of the increase of blood sugar: sugar is an acid-producing food, which can neutralize the basic calcium and chromium in the body and is one of the substances that maintain the elasticity of the eyeball. When the nutrition is balanced, the calcium and chromium in the body are also in a balanced state, keeping the intraocular pressure normal; When calcium and chromium are insufficient, the elasticity of eye wall decreases and normal intraocular pressure cannot be maintained. Long-term tension with eyes will lengthen the axial length and cause myopia. In addition, the increase of blood sugar will accelerate the degeneration of lens, cause the change of osmotic pressure of lens and aqueous humor, increase diopter and lead to myopia.
