1, the unhealthy ingredient in the beverage is mainly sugar;
2. So sugar-free drinks are definitely healthier than sugary drinks;
There are many sources of sugar intake for human body. It is not enough to control sugar intake by drinking sugar-free drinks as a whole.
Sugar is an indispensable compound and energy source for human body, but the problem is that modern people consume too much sugar. Moreover, the sugar mentioned in Nutrition is not only white sugar, brown sugar and rock sugar ... carbohydrates such as staple food and starchy food are also sugar. Most snacks, cakes and desserts contain a lot of carbohydrates.
Needless to say, the health problems caused by excessive sugar intake have long been known that many drinks contain high sugar content. But how high is it?
According to the recommendation of 20 16 Dietary Guidelines for China Residents, the sugar intake per person per day should not exceed 50g, and it is better to control it at around 25g, while the sugar content of a can of carbonated drinks often reaches 30g, which is more than the recommended value for one day.
In addition, the calories in drinks basically come from sugar. So the harm of sugary drinks to health is self-evident.
This problem really can't be explained clearly in one or two sentences.
Judging from the composition of the beverage, sugar-free beverages use various sweeteners to replace the sugar added in sugary beverages, including white sugar and fructose syrup. -this part of the sugar is definitely gone.
So, is there any sugar in the sweetener?
At present, there are many sweeteners used in beverages, most of which have nothing to do with sugar, but a few of them belong to carbohydrates, such as "erythritol" which is often used in sugar-free beverages such as Yuan Qi Forest. So you can see that "sugar" is 0, but "carbohydrate" is not 0. The carbohydrate here is erythritol.
But since erythritol can be used instead of sugar, it is still different from sugar. This substance is not degraded by enzymes, nor does it participate in sugar metabolism and blood sugar changes, but is excreted with urine. Therefore, if you "drink" carbohydrates but don't "ingest" them, it won't have any impact on your health.
Artificial sweeteners have been used in the beverage industry for a long time. Saccharin, sodium cyclamate, aspartame, sucralose and acesulfame K were widely used in the early days. These sweeteners are all synthetic chemicals. Although they contain no sugar, they have no nutritional value.
The safety and health effects of these artificial sweeteners have been controversial, but all governments have approved them as legal food additives. Moreover, because the sweetness of artificial sweeteners is much higher than that of sugar, the content of artificial sweeteners in beverages is very low. "Talking about toxicity without dosage is hooliganism", so we can generally think that as long as you don't drink a few tons of sugar-free drinks every day (and no one has the ability), you don't have to worry about the harm these sweeteners will do to the human body.
In recent years, natural sweeteners stand out and tend to replace artificial sweeteners. Erythritol and stevioside are representative. Many new bottled drinks choose erythritol, while tea shops such as Xicha and Lele Tea all offer the option of using stevia instead of sugar.
Many people criticize sweeteners not for their own safety, but because their "sweetness" deceives the brain-the brain receives the sweetness signal, but does not ingest sugar, which will lead to its desire for real sugar.
This statement is reasonable in theory, but people are rational after all. Even if the brain craves sugar, as long as you insist on not eating it, there will be no problem. As for whether you can hold back, you can only say that it varies from person to person. The only thing that needs to be reminded again is that staple food, cakes and snacks are also sugar. It is not enough just not to drink sugary drinks, but also to eat less of these things.
Conclusion: Replacing sugary drinks with sugar-free drinks is definitely more beneficial to health. However, you still need to control the sugar intake as a whole. Don't drink sugar-free drinks, and don't eat foods with too many carbohydrates. In other words, if you generally eat a small amount of carbohydrates, it is okay to drink sugary drinks.
