Sugar-free drinks are not necessarily sugar-free, so-called sugar-free means no sucrose. But no sucrose doesn't mean no sugar. For example, some sugar-free foods are made of grains and are polysaccharide foods, which can be decomposed into sucrose and glucose in the body. Generally speaking, it is not really sugar-free. The sugar content of sugar-free products is less than 0.5g, but in order to improve the taste of food, a small amount of sweetness may be added to the food, which can improve the taste. Diabetic patients should take hypoglycemic drugs on time under the guidance of doctors in their daily lives, and their blood sugar should be controlled within a suitable range.

For the sake of health or weight loss, many people prefer sugar-free drinks, thinking that sugar-free drinks are low in calories and will not lead to obesity. So, is this a fact? As we all know, too much sugar intake will bring about overweight, obesity, dyslipidemia and other hazards, so some friends began to "exercise" and chose sugar-free drinks, thinking that it would be much better for the body. In fact, the so-called "sugar-free" beverage does not really contain sugar, but refers to the fact that the sugar in the beverage is lower than the standard "zero" limit. According to national standards, foods with sugar content less than or equal to 0.5g per100g or per100ml can be marked as "sugar-free". Sugar here usually refers to white sugar, sucrose, glucose and so on.

According to this calculation, a bottle of 500 ml "sugar-free" beverage should add no more than 2.5 grams of sugar, while the World Health Organization recommends that the daily amount of sugar should not exceed 25 grams, which is equivalent to 10 times of a bottle of sugar-free beverage. Therefore, if you need to control energy intake, you can choose sugar-free drinks between ordinary drinks and sugar-free drinks, but because "sugar-free" drinks actually contain sugar, you should never drink sugar-free drinks as drinking water.

In addition, many people may wonder why drinks are still sweet without sugar. This is because, in order to enhance the taste, sweeteners such as xylitol, aspartame, acesulfame K and sodium cyclamate will be added to the beverage. More and more studies have found that some sweeteners may cause adverse consequences such as metabolic disorder and intestinal flora imbalance. So if you want to replenish water, try to drink boiled water and light tea, and don't drink too much.
