White sugar is generally divided into white sugar and soft sugar. According to the nutrient composition table, the sugar content of white sugar is 99.9% and that of soft sugar is 98.9%. The main ingredient is sucrose, and the contents of vitamins and minerals are almost negligible. It is a typical empty calorie food, that is, it has no nutritional value but high calorie. We should eat as little as possible, not to mention its nutritional value and even its magical health care function.
There is ample evidence that excessive intake of sugar (including white sugar, rock sugar, brown sugar and honey) will increase the risk of obesity, dental caries and diabetes. The World Health Organization suggests that the daily sugar intake should be reduced to less than 10% of the total energy, and further reduction to less than 5% (about 25 grams per day) will be more beneficial to health.
You know, a small can of 330 ml cola has a sugar content close to 40 grams, and the sugar intake is easy to exceed the standard. Therefore, sugar is an empty calorie food, which has no nutritional value, is not conducive to health and is easy to eat. What we need to do is to reduce the intake of sugar.
White sugar, that is, white sugar with sucrose as the main component, is a sweetener extracted from sugarcane or beet and a gift given by nature. Natural, safe, non-toxic, sweet and pleasant, and can also be used as the main energy source to maintain people's normal physiological functions and daily activities.
After people eat white sugar, it will be decomposed into glucose and fructose in the digestive tract. These sugars will be absorbed by people and transported to all parts of the body through blood for oxidation and utilization by all tissues and cells. The energy it produces accounts for almost 70% of the total energy needed by people every day, which is used for muscle consumption of various tissues of the body and maintaining normal body temperature.
In addition, sugar has certain medicinal effects. It is mild in nature and sweet in taste, and has the effects of clearing away lung-heat, moistening dryness, promoting fluid production to quench thirst, invigorating middle warmer, benefiting qi, relieving cough and resolving phlegm, sobering up and detoxifying. It is often used to treat diarrhea due to spleen deficiency, cough due to lung heat, dry mouth and tongue, scabies, beriberi and bittern poisoning.
Many people do not know for what purpose, distort the role of sugar, and often say that eating too much sugar will lead to obesity, diabetes, lithiasis and other diseases; But modern research has proved that obesity is not necessarily related to eating sugar, and eating sugar will not lead to diabetes. The main component of white sugar is sucrose, and its glycemic index is 83, while the glycemic index of white flour steamed bread is 88. Therefore, if eating sugar can lead to diabetes, then everyone who eats steamed bread will have diabetes. Of course, we mean that eating sugar will not lead to diabetes, but it does not mean that diabetes can eat too much sugar;
The nutritional value of sugar is not high, but people can't live without it. Even so, you can't eat too much white sugar. People with diabetes and phlegm-dampness constitution had better eat less, and it is not suitable to eat sugar before going to bed at night, which is easy to cause stomach acid!
