Strictly speaking, sugar-free drinks should be sugar-free drinks, such as soda water and tea. These sugar-free drinks have no sweetness. Drinks using sugar-free sweeteners and other sugar substitutes can also belong to the category of sugar-free beverages, because xylitol, acesulfame K, aspartame and other sugar substitutes will not increase blood sugar after entering the human body, but will be excreted with urine.
Many sugar-free foods on the market just confuse the concept with the slogan of sugar-free. For example, some sugar-free items do not contain sucrose, or fructose, glucose, maltose and other sugars, which are advertised as sugar-free. In fact, they also contain other types of sugar in essence. Therefore, consumers must read the ingredient list clearly to determine whether the food they buy is really sugar-free.
In the ranks of sugar-free drinks, only green tea, black tea, scented tea and other drinks brewed by yourself can really reassure people. Sugar-free drinks on the market will use sugar substitutes and other food additives. Although sugar substitutes will not raise blood sugar, excessive intake is still harmful.
Sugar-free sweeteners tend to be far sweeter than natural sugar. Excessive intake of sugar substitutes will interfere with the metabolism of fat and amino acids in the body and affect the state of nervous system and endocrine. The body feels sweet, but it can't get energy, which is also a contradictory state. It will further lead to endocrine disorders, strengthen the desire and hunger for sweets, and thus induce excessive intake of sweets.
In addition, it is inevitable to add various food additives to any commercially available beverage. Although a small amount of food additives is within the safe range, its impact on health is still controversial. Drinking drinks without restraint will only increase the metabolic burden of liver and kidney, interfere with the absorption and utilization of normal nutrients by human body, and is also unfavorable to health.
