Difference between health care products and functional health food

Hello. There are essential differences between health care products and health food. The health products are made into finished products, tablets, powders, capsules and liquids. Strictly speaking, health food belongs to the category of homology of traditional Chinese medicine and food, such as lotus seeds, medlar, jujube, black beans, coix seed, fungi and so on. However, some manufacturers of health care products deliberately turn the word "food" added to health care products into health food for the sake of gimmicks, so that customers feel that "I am a food, it is natural", which is actually a change of soup. There are also some foods called nutritional supplements, which basically appear in the name of nutrients, rather than being replaced by another name.
