What harm can eating too much sugar bring?
1, causing dental caries
There are many bacteria living in our mouth. If we often eat a lot of sugary food, these bacteria will decompose and ferment the sugar left in our mouth. This process will produce a certain amount of acidic substances, which will erode our teeth. Many children's dental caries are caused by their love of sweets. Therefore, brush your teeth or rinse your mouth in time after eating sweets to avoid dental caries.
2, leading to obesity
After being digested and absorbed by human body, some sugar foods consume energy, and the other part is stored as glycogen in muscle and liver. In addition to meeting the needs of the above two parts, the remaining large amount of carbohydrates will be converted into fat in the human body. Human and animal experiments also show that high fructose syrup containing a lot of fructose can cause excessive fat precipitation. In addition, sugar can inhibit the disappearance of hunger and promote our eating by acting on the nervous system. Therefore, eating a lot of foods with high carbohydrate content for a long time can easily cause obesity. If we eat more than 5 pieces of sugar every day, it is equivalent to an extra intake of nearly 100 kilocalories, and our weight will increase by 100 grams per week.
3. Induced hypertension
A survey of sugary drinks in the United States shows that drinking one can of sweet drinks a day is 20% more likely to develop diabetes than not drinking sweet drinks, and drinking two cans a day is 50% higher. In recent years, the increase in the number of diabetic patients is closely related to the large consumption of sweet drinks and the increasing intake of sugar year by year. Nutritionists found that eating sugar may not directly lead to diabetes, but long-term consumption of sweets will lead to excessive insulin secretion and disorder of carbohydrate metabolism, which will lead to imbalance of human internal environment, and then lead to diabetes.
4, lead to osteoporosis
The metabolism of sugar food in the body needs to consume a variety of vitamins and minerals. Therefore, eating sugar often will cause nutritional problems such as vitamin deficiency and calcium deficiency. When the body is in a state of high sugar for a long time, urine sugar will occur. When sugar is excreted in urine, water-soluble vitamin B 1 and calcium ions in blood are excreted too much. Research shows that the vitamin B 1 urine output of patients with type II diabetes is as much as 16 times that of normal people. Vitamin B 1 is a necessary substance for sugar to convert energy in the body. If vitamin B 1 is insufficient, it will greatly reduce the activity of nerves and muscles, which will easily lead to falls and fractures. The loss of calcium ions in blood will cause the calcium in bones to dissolve into blood continuously, which will eventually lead to osteoporosis.
5. Easy to get kidney calculi
We all know that drinking boiled water can prevent kidney calculi, but if you put more sugar into boiled water and drink sugar water, it will promote the occurrence of kidney calculi. As mentioned earlier, the higher the sugar content of the body, it will lead to the loss of nutrients such as sugar and calcium with urine. Studies have shown that both normal people and patients with stones, after eating100g of sucrose, checked their urine two hours later, and found that the concentrations of calcium and oxalic acid in urine increased. The higher the calcium content in urine, the greater the chance that they will meet oxalic acid to form a precipitate, and then it is easy to get kidney calculi. It is not difficult to understand why many people have kidney calculi and calcium deficiency at the same time.
Invisible sugar in diet can not be ignored
Why do some children seldom eat sugar, but the amount of sugar they can take will still exceed the standard? Fan Zhihong, a nutrition expert, told reporters that most of the sugar in life is invisible in drinks, sweets, bread, snacks, biscuits, energy bars, jam, jelly, candied fruit, ice cream, instant paste powder and other foods. For example, if you drink a can of 330 ml coke, you will consume about 35 grams of sugar; Drink a bottle of 430ml fruit juice, and you will consume about 45g of sugar. A few sweet biscuits contain about 10 g of sugar, etc., which may have unconsciously taken in the amount of polysaccharide. The World Health Organization suggests that both adults and children should limit the intake of free sugar to less than 10% of the total energy intake every day.
In addition, especially in Guangdong, daily families love to cook soup and sugar water, and there are also many invisible sugars in seasoning. For example, red bean paste and mung bean paste should be made with sugar, tremella soup should be cooked with rock sugar, pear soup should be stewed with rock sugar, braised meat should be sweetened to enhance freshness and color, and tomatoes, eggs and vinegar-baked cabbage should be sweetened. Therefore, it is necessary to control children's sugar intake and pay attention to their usual diet.
Eating too much sugar may cause or aggravate myopia.
It is understood that sugar is one of the three major nutrients and an important source of human heat. Timely and appropriate intake of sugar can maintain the normal physiological function and health of the human body, but if it is eaten in excess, it will harm the body and induce diseases.
In recent years, myopia has a tendency to develop to a lower age group, and more and more children wear glasses. Chen Siping, a physician at the Optometry Center of Zhejiang Eye Hospital, said that it is not a rumor that children eat too much sugar to cause myopia, and too much sugar intake may also increase the incidence of myopia or aggravate the degree of myopia.
Chen Siping pointed out that when too much sugar enters the human body, the high blood sugar content will cause changes in aqueous humor and lens osmotic pressure. If the osmotic pressure of aqueous humor is lower than that of the crystal, aqueous humor will enter the crystal and change the shape of the crystal, which may induce myopia or aggravate myopia. In addition, excessive sugar may reduce the elasticity of intraocular tissue, increase the pressure in the lens, lengthen the axial length of the eye, and cause myopia or aggravate the development of myopia.
In addition, the metabolism of sugar in the body also needs the help of vitamins. Excessive sugar will cause a large number of nutrients such as vitamin b 1 to be consumed. Vitamin b 1 has the function of nourishing the optic nerve. If the optic nerve is not adequately nourished, it may cause or aggravate the degree of myopia.
