In order to control their weight, many people choose to eat fat-free foods. Others believe that if a selected food is labeled "low calorie," it must mean they are not gaining weight and will be healthier eating it. But is this true? Nowadays, many food merchants are launching sugar-free and fat-reducing products in order to win over people's hearts. Sugar-free cola and zero-calorie sodas are irresistible to those who love sweets and want to lose weight. Have you noticed the zero-calorie, zero-fat delicacies appearing on the supermarket counter? However, zero calories and zero fat are really zero calories? Nutrients contained in food include carbohydrates, lipids, proteins, minerals, vitamins and water. Among them, carbohydrates, fats and proteins can all produce energy through oxidation in the body, so these three are called energy-producing nutrients.

According to the regulations of the Department of Health, if it is labeled with zero calories, it means that the calories contained per 100 grams or per 100 ml shall not exceed 4 calories; if it is labeled with low calories, it shall not exceed 40 calories. If packaged food is labeled as sugar-free, the sugar content shall not exceed 0.5 grams per 100 grams or per 100 ml; if it is labeled as low-sugar, the sugar content shall not exceed 5 grams. Therefore, sugar-free or low-sugar does not mean that it has 0 calories.

0 Fat only indicates the fat content in the drink and does not equate to health. The impact of drinks on health depends on whether the drinks contain energy and other ingredients. Therefore, 0 fat does not mean 0 calories. If it contains carbohydrates and added sugar, it still contains energy. So even foods labeled as zero calories should be eaten in moderation.
