According to the different raw materials and product forms, soft drinks can be divided into eight categories: carbonated drinks, juice drinks, vegetable juice drinks, milk drinks, vegetable protein drinks, solid drinks, natural mineral water drinks, and other drinks such as orange juice, bayberry juice and tea drinks. First of all, we should pay attention to the variety and dosage of sweeteners and preservatives. This dose should be as small as possible. For example, an adult weighing 60 kg should not consume more than 150 mg of saccharin per day, while the maximum daily limit for others per kilogram of body weight is 1 1 mg of sodium cyclamate, 40 mg of sodium cyclamate, acesulfame K 15 mg, 5 mg of sodium benzoate and 25 mg of potassium sorbate. It is suggested to choose drinks containing natural additives as far as possible. Secondly, carefully identify the contents of the label. Third, special people, such as children and pregnant women, should stay away from foods containing more synthetic additives and take more natural nutrients. Fourth, choose the taste that suits you. Fifth, understand the efficacy of drinks. There are two kinds of drinks: nutritious and non-nutritious Nutritional drinks include fruit juice, vegetable juice and milk. Note that there is no word "beverage" on the package of this kind of beverage, which is mainly nutritious and supplemented by quenching thirst.
