Nowadays, the harm of high sugar intake has attracted increasing attention, and sugar free food has become a new favorite in the food industry. However, under the publicity of merchants, there are misunderstandings in the public's understanding of sugar free food. Sugar free food, the new favorite of the food industry, is located in a supermarket on Jinkai Avenue, Yubei District, Chongqing. A group of shelves are neatly placed with sugar free biscuits, sugar free oatmeal, sugar free sesame paste and other foods. The signs beside the shelves clearly indicate "sugar free food area". The staff pointed to the words "no sugar", "Zero sugar" and "no sugar" on the food package and stressed to the reporter: "sugar free food is food without any sugar added." "I haven't checked. Sugar free should be completely sugar free." Mr. Wang started to lose weight in March this year. He only eats sugar free oatmeal every night. At present, his weight has not changed significantly, but he still insists on buying sugar free food. The reporter visited six large-scale comprehensive supermarkets at random, all of which have sugar free food zones. Among them, the sugar free cola with the highest sales volume even became a district alone, and the slogan "sugar free, enjoy delicious" can be seen from afar. "This is for the elderly with diabetes at home. If the diabetic needs to control blood sugar, we can only choose sugar free food." Miss Dai, who is picking up sugar free biscuits in the supermarket, said that the old people in the family can eat a packet of sugar free biscuits every 3 to 5 days. Because there is no sugar, the children can rest assured that the old people can eat them. Is sugar free food really "sugar free"? Sugar free is not "Zero sugar". The reporter inquired about the relevant national food safety standards and found that as long as the sugar content per 100 g or 100 ml of solid or liquid food is not more than 0.5 g, it can be labeled as sugar free food. This means that consumers of sugar free food who want to strictly control their sugar intake may not be able to eat such food without restraint. Insiders pointed out that long-term consumption of sugar free food will also increase energy intake, but it is easy to cause obesity. It is worth noting that sugar free foods, especially sugar free beverages, are often free of caffeine, which makes people "addicted". "I like to eat sweet food more and more. The food that others think is very sweet is just right sweet in my mouth." Ms. Jia, who has eaten sugar substitutes for more than a year, said. "No sugar" does not mean no sugar. The reporter took a bag of sugar free ShaQima and asked the salesperson of the supermarket. The salesperson thought that no sugar means no sugar. There is no difference between the two. However, a brief look at the ingredients table shows that the main raw material of this ShaQima is maltose syrup, and maltose also belongs to sugar. "No sucrose" only means that sucrose is not added, but glucose, maltose and other sugars can be added completely, which is not equivalent to "no sugar". Sugar free may have sugar substitutes. In the ingredient list of several sugar free yoghurt, the reporter did not find any sugar, but found the names of xylitol, trimer sucrose and other sugar substitutes. Professionals explain that although sugar free food cannot add sucrose and sugar from starch hydrolysates, it must contain substitutes corresponding to sugar. Generally, sugar alcohols or oligosaccharides and other sweeteners that do not increase blood sugar are used. It should be noted that sugar substitutes are not easy to absorb, and excessive intake can easily cause abdominal pain and diarrhea. Sugar free food, how to eat sugar free food with caution
