According to the data, the scientific label of the "new weapon to lose weight" contained in Diet Coke is "Fibersol-2", which is a water-soluble dietary fiber from corn starch introduced by Matsutani Chemical Industry Co., Ltd. in Japan on 1988. 50% of this fiber will not be digested and absorbed by human body, so it is called "indigestible maltodextrin". "From a nutritional point of view, Diet Coke is only interested in the principle and function of this dietary fiber to clean the intestines and inhibit fat production." Theoretically speaking, the ingredients of Diet Coke are still innovative and progressive.
What's the difference between this diet coke and ordinary coke?
1, Diet Coke tastes like "zero". In taste, Diet Coke is not much different from ordinary Coke, with sweetness and foam stimulation of carbon dioxide. Wang Shuang, a postdoctoral fellow at Waseda University, told the Science and Technology Daily reporter, "But if you keep drinking it, you will feel that the sweetness of Diet Coke is getting weaker and weaker, which is not as lasting as the stimulation of ordinary coke, and the overall taste is close to the' zero coke' launched before."
2. The packaging and nutritional components are different. Perhaps it is deliberately trying to create a sense of identity different from ordinary coke. Diet coke is designed with white package and red font, which is just the opposite of the common white coke with red background. However, the nutrient composition table of its product shows that a bottle of 470 ml Diet Coke has zero energy, protein and fat content, and only 5.2 grams of carbohydrates. Coca-Cola Japan said that while trying to preserve the original flavor of Coca-Cola, they added "indigestible maltodextrin" to it. This substance is mainly used to inhibit fat absorption and stabilize blood lipids without generating more calories.
The price is about twice as high as ordinary coke. Although the slimming effect of Diet Coke has yet to be verified, its price is about twice as high as that of ordinary coke, that is, 470 ml158 yen per bottle, which is about RMB 9.8 yuan. The higher price is a symbol of the value of indigestible maltodextrin, because its existence gives Coca-Cola a reputation of "slimming". According to the recommendation of Dietary Guidelines for China Residents, the average daily intake of dietary fiber for normal adults is suggested to be 25 to 30 grams, so it is more scientific and sufficient to put 5 grams of dietary fiber in a bottle of diet coke, and the rest can be obtained from vegetables, fruits and whole grains.
Can Diet Coke be drunk in public? A 355 ml can of aspartame and sweetened carbonated water contains about 200 mg of aspartame. After digestion, aspartame produces one tenth (20 mg) of its weight in methanol. The data show that enzymes in the liver will decompose methanol into two highly toxic compounds. At present, the biggest controversy in academic circles is whether these toxins decomposed by methanol in aspartame are enough to harm the body.
In addition to the possible health effects, scientists also suspect that aspartame will make people more appetizing. According to the data, a cancer society in the United States followed up 8,000 women for six years, and finally concluded that among the participants who gained weight, women who ate artificial sweeteners gained more weight than those who never ate them.
In order to prolong the shelf life of food, it is reasonable and legal to use food additives to some extent. However, from the point of view of nutrition, aspartame is not a nutrient element needed by human body, but an artificial additive. The human body can metabolize the dose within a limited range, but the less the better. The nutrients carried by vegetables, fruits and grains are what the human body really needs.
