In the United States, the most common type of Health food used is the vitamin-mineral complex, followed by vitamin C, vitamin E, and calcium. In the 1999-2000 study, 35 percent of Americans used vitamin-mineral complexes. The situation is similar in Japan and Korea. There is some variation in the types of vitamins used by different populations. In the United States, the highest use of iron is among young and middle-aged women, calcium is among middle-aged and older women, and vitamin E is among older adults, but there is no difference between the sexes. Next, let's take a look at the purpose and rationale for the use of Dietary Supplement. Here are some answers.
Here is the content list:
l The purpose of Dietary Supplement used.
l Reasonableness of Dietary Supplement used.
Studies have shown that people use Dietary Supplements to maintain or improve their health, to prevent dietary deficiencies, and to treat or assist in the treatment of diseases, the latter being common among dieters, menopausal syndrome patients, and breast cancer patients. The latter is common among dieters, menopausal syndrome patients, breast cancer patients, etc. Not many studies have asked for "prevention of disease", but many studies have not asked for this explicitly, which may be an underestimation and therefore needs to be further investigated. There are some differences in the purpose of use among different groups. Older users tend to use Dietary Supplement as a "therapeutic measure"; women who use multivitamins primarily to "maintain health"; and college students to "provide adequate nutrition and maintain a healthy lifestyle. Women who use multivitamins mainly use them to "maintain health"; college students mainly use them to "provide adequate nutrition and maintain physical strength", and they prefer to "enhance and improve". The different purposes reflect the different health needs and deep psychological motives of people, and research in this area is still relatively shallow and needs to be further developed.
Dietary supplement overdose and underdose are common. According to the 1987 NHIS, the 95th percentile of Immunity increases users consumed more than twice the recommended dietary allowance (RDA) for vitamin A, seven times the RDA for riboflavin, and 17 times the RDA for vitamin C. The results of this study showed that 3% of users were consuming vitamin A at teratogenic doses, that the median total daily intake of iron for pregnant women and lactating mothers exceeded the tolerable maximum intake, and that many users of calcium and zinc supplements were still consuming less than the RDA or even below the average requirement (EAR) for the respective nutrients. Similar problems exist in Australia and Korea. The main reasons for this are that users lack professional guidance, adjust the dosage by themselves, or use multiple Dietary Supplements together, and because of the vague definition of the scope of application of some products, users misunderstand the product descriptions, resulting in abuse or under dosage.
The population distribution of Dietary Supplement users is not reasonable. The use rate of Vitamins is low in high-risk groups but high in relatively safe groups. A study of iron supplement use among women in the United States showed that the use rate among low-income women was less than 50% of that among high-income women, the use rate among Mexican-American women was less than 70% of that among non-Hispanic women, and the average daily intake of iron among women over 50 years of age was higher than that of women of childbearing age.
