In October, "all science and technology and ruthless work" became the most popular "stem". The emergence of this hot spot has aroused people's attention to food safety, and rumors related to it have also been widely spread, such as "sugar substitutes can be eaten openly", "only zero addition is good soy sauce"... Rumors about the COVID-19 still occur from time to time, such as "scanning the code when leaving the public place can avoid becoming a secret contact". In addition, the drought in some parts of China a while ago made the rumor that "as long as there are clouds, rain can be artificially increased" spread widely. Today, the reporter of Science and Technology Daily made an inventory of the rumors that appeared in October one by one to help you dispel the fog and find the truth. Can sugar substitutes be eaten openly? Truth: A large intake of sugar substitutes also has health risks. With the approaching of winter, people's time for outdoor sports gradually decreases. Many people begin to worry about insufficient calorie consumption, so they pay special attention to controlling calorie intake. Sugar substitute drinks and snacks marked with "zero sugar" and "zero calorie" seem to contain no calories. Some people therefore believe that sugar substitutes are healthy and can be eaten without carrying the "sweet burden". So, is that really the case? "This view is wrong. Sugar substitutes should also be eaten reasonably. Large amounts of them also pose health risks." Zheng Yunliang, director of Tianjin Institute of Modern Health Technology, said. According to the data, sugar substitutes refer to alternative sweeteners, belonging to food additives, which mainly fall into three categories: natural sweeteners, sugar alcohols and artificial sweeteners. At present, most sugar substitutes on the market use artificial sweeteners, such as aspartame. Such sweeteners do not exist in nature, but are chemically synthesized. "From the perspective of energy generation, sugar substitutes can be divided into nutritive and non nutritive ones. Almost all the decompositions of non nutritive sugar substitutes in the human body do not contain glucose and do not directly participate in the secretion of insulin. Therefore, in theory, non nutritive sugar substitutes will not cause the rise of blood sugar." Zheng Yunliang said. However, this does not mean that we can eat sugar substitutes openly. "The sweetness of sugar substitutes can stimulate appetite. Excessive intake or diarrhea may also increase the burden on the kidneys." Zheng Yunliang further said that, with the progress of science and the deepening of research, most scientific research results show that artificial sweeteners may have a risk of disease. For example, on September 7, 2022, the British Medical Journal published a large research result from France. This study shows that there is no benefit to the cardiovascular and cerebrovascular health of the whole population if artificial sweeteners are used to replace sugar in foods or beverages. Cell also published a related study, which found that the intake of artificial sweeteners was related to changes in intestinal microbiome and elevated blood sugar. Therefore, Zheng Yunliang suggested that consumers should try to choose foods containing natural sweeteners when choosing sugar substitute foods, such as erythritol, stevioside, siraitin, and stevioside. "It is safe to eat sugar substitute food or drink occasionally, so everyone should not be too nervous. The public should scientifically understand and eat sugar substitutes, and improve their health through scientific and reasonable diet and exercise." Zheng Yunliang said.
