There is a high obesity rate in Taiwan's elementary and middle schools. A Kuomintang legislator proposed to amend the "School Sanitation Law" to prohibit the sale of high-salt, high-oil, high-fat foods and sugar-sweetened beverages in schools below high school. It's just treating the symptoms, not the root cause. Toxicology expert Zhao Mingwei also said on Facebook that sugar-sweetened beverages should be withdrawn from school, but the restriction will only teach more mothers, so it is more realistic to focus on promoting the concept of healthy eating.
Should I quit campuses below high school for sugary drinks? Toxicology expert Zhao Mingwei said: "From the perspective of a poison expert, I think it is time to quit the school, and not only below high school, I even think that all schools should not sell sugary drinks, after all, too much sugar. , it will not only cause obesity, but also damage the brain and hinder learning.”
Zhao Mingwei explained that the raw materials of sugar-sweetened beverages on the market are mostly added with "fructose"-based added sugar, which has a low nutrient density. When excessive intake of sugar, sugar will combine with protein to form glycosylated protein. This mutated protein will flow to all parts of the body with the blood, accidentally inflaming the body. If it cannot be ruled out for a long time, obesity, aging , diabetes, metabolic syndrome, cardiovascular disease and brain lesions will greatly increase the risk.
When it comes to the brain, however, Zhao Mingwei believes that consuming "the right amount" of sugar is not necessarily a bad thing. When we eat sugar, the taste receptors on the tongue receive the sweetness message, which triggers the nerve cells in the brain to release the hormone "dopamine", which makes us feel satisfied and happy, much like inhalingLike nicotine, there will be addictions such as "craving for sweets".
But if you eat "excessive" sugary foods, the function of pleasure will be blocked, especially the brain-derived neurotrophic factor responsible for reducing anxiety, fear, and stress response will be greatly reduced, resulting in depression and bipolar disorder. The incidence of both will increase.
Zhao Mingwei also cited a study conducted by the University of California, Los Angeles on rats, which found that continuous consumption of high fructose for 6 weeks, the rat's brain response would gradually become sluggish, and the synaptic response of nerve cells also decreased significantly. Worst after 6 weeks. If humans also consume too much sugar, unfortunately this will also end. In addition,
How much sugar is too much? For example, an average adult weighing 50-60 kg needs about 1500-1800 calories per day, and the sugar intake should not exceed 150-180 calories, that is, 37.5-45 grams of sugar (about 7-9 Sugar cubes, each gram of sugar can produce 4 calories), take hand shake as an example, a large cup of full sugar oolong tea (about 700 ml), plus about 57.4 grams of sugar (about 230 calories), drink 1 cup Daily limit exceeded.
Zhao Mingwei emphasized that cognitive education is the most important, and ignorant restrictions will only teach more mothers! He said: "If the campus cannot sell these foods, students can eat them outside the school, and even eat them when they want to go home. If it is only mandatory, it is better to strengthen the promotion of the concept of healthy eating and inform the standard for calculating sugar doses. , for students and the general public to practiceIt is more practical to control the "moderate" diet by yourself!
