1, define your own needs.
Some people may think that eating too much health food will not have any side effects. Actually, this is not the case, especially for people with diseases. Therefore, before buying health food, you must know whether you need to supplement it. Because food safety is higher, general nutrient supplements are mainly complementary foods. When the diet can't meet the nutritional needs, you can consult a nutritionist for nutritional evaluation, and then choose targeted health food for conditioning.
With regard to the dosage of supplements, generally speaking, the sum of the nutrient content of supplements and the intake of nutrients in the diet can reach the intake recommended in the Reference Intake of Dietary Nutrients for China Residents (20 13). For example, taking calcium supplementation as an example, an adult male in China needs 800mg per day, which can reach about 500mg through diet, so he only needs to supplement 300mg of calcium to meet the body's demand for calcium.
2. Purchase through formal channels
Generally speaking, large supermarkets and chain pharmacies are less likely to sell unqualified products because of the supervision of relevant departments and the consideration of maintaining their own reputation. Even if consumers buy unqualified products, they will not be unable to defend their rights. Therefore, it is recommended to buy health care products in these formal places and avoid buying products through marketing.
In addition, health food also has a unique identity, that is, "police mobile force." According to the relevant regulations, only wearing a small blue hat is a regular health food, otherwise it can only be used as ordinary food and cannot claim related health functions, so everyone must look for the police tactical team when buying health food!
Don't believe the salesman's sweet words.
According to the regulations of the US Food and Drug Administration, health foods are allowed to claim 27 health functions. If a product claims that its functions are not among these 27 functions, or that it has more than two functions, or that it can cure all diseases and even replace medicines, then this product is definitely not a regular health food.
In addition, due to the uneven level of most salesmen, it is not uncommon to exaggerate the health care efficacy of products in order to promote sales. Therefore, when buying products, please don't believe what the salesman says. You can log in to official website of China Food and Drug Administration to check the authenticity of the problem products, so as not to be deceived.
Extended data
Health care products cannot replace medicines.
According to the definition of health food by the State Food and Drug Administration of the United States, health food refers to foods that claim to have specific health care functions or are aimed at supplementing vitamins and minerals, that is, foods that are suitable for specific people, have the function of regulating the body, are not aimed at treating diseases, and do not cause any acute, subacute or chronic harm to the human body.
Like ordinary food, health food can also provide basic nutrition necessary for human body, and has specific color, fragrance, taste and shape; The difference between them is that health food contains a certain amount of functional ingredients (physiologically active substances), which can play a role in regulating human functions. Health food has its specific consumption range. For example, obese people can supplement health food with the function of losing weight.
Although health foods exist in the form of tablets, oral liquids and capsules like medicines, we should not think that health foods can treat or prevent diseases like medicines.
The difference between the two is that drugs are substances for treating diseases; The essence of health food is food. Although it has the function of regulating some functions of human body, it is not a substance that human beings rely on to treat diseases. To sum up, health food is neither ordinary food nor medicine. Since it is food, we can't expect it to cure diseases.
