Most sugar-free drinks have sugar substitutes to keep the sweetness. The so-called zero calorie is not really zero, but the calorie of sugar substitute is greatly reduced.
Does the "zero calorie" drink really have no calories at all?
According to the National Food Safety Standard: General Rules for Nutrition Labeling in prepackaged foods, if the content of fat and sugar is less than or equal to 0.5g per 100ml, it can be labeled as "zero fat" and "zero sugar", and if the energy of beverage is less than or equal to 17kJ (4 kcal) per 100ml, it can be labeled as.
Therefore, even the beverage labeled "0 sugar, 0 fat and 0 calories" does not mean that it contains no sugar and no calories at all, but the content is relatively low and can be ignored.
Compared with high-sugar drinks and milk tea, 0-sugar 0-calorie drinks are indeed less likely to cause obesity. But drinking sugar-free drinks for a long time is not good for losing weight. Drinking sugar-free drinks for a long time will increase the love and desire for sweet mouth.
Although sweeteners are mostly approved for use, long-term excessive drinking will still bring the following health risks ~
1, artificial sweetener
Artificial sweeteners: saccharin sodium, sucralose, acesulfame, aspartame, sorbitol, maltitol, etc.
Synthetic sweeteners will be digested and decomposed by intestinal bacteria and microorganisms, changing the types of intestinal flora and affecting glucose tolerance. Glucose tolerance is an index of insulin resistance. From the results of observational studies and animal experiments, the evidence that sweeteners originally used to lose weight cause obesity and metabolic diseases is sufficient. So friends who want to lose weight should drink as little as possible.
2. Natural extraction of substitute sugar
Natural sweeteners: xylitol, stevioside, mogroside, etc.
In addition to synthetic sweeteners, another sweetener that is used more and more is sugar alcohol. Sugar alcohols naturally exist in many fruits, and some sugar alcohols are refined into sweeteners, especially erythritol. 90% of erythritol we drink will be excreted directly through urine, and the remaining 65,438+00% erythritol will be excreted through feces, which will not be absorbed by human body or intestinal bacteria at all. Erythritol is a relatively safe sweetener at present.
However, many studies have found that this kind of "0 sugar" drink with light sweetness but no calorie input will make people confused. Under the guidance of wrong signals, it will increase the appetite of drinkers and take compensatory energy intake to get satisfaction after meals, so it is easier to make people fat.
In addition, many "zero sugar" drinks contain carbonic acid and phosphoric acid, which are also harmful to teeth. So don't think you are completely healthy and can drink indefinitely at the sight of the words "sugar-free", "zero calorie" and "fiber".
Health index ranking:
Natural sugar substitute > sugar alcohol > artificial sugar substitute, natural sugar substitute and sugar alcohol are relatively healthy sugar substitutes, and artificial sweeteners should be eaten as little as possible.
Finally, although this drink is relatively healthy and a good substitute, it should be drunk in moderation. If you have to drink it, you can choose sugar-free black coffee or oolong tea. I mean the kind that has no sweetness at all.
