Malnutrition is often associated with many diseases, such as cancer and heart disease. The human diet requires both macronutrients (an important source of calories) and micronutrients (about 40 essential minerals, vitamins and other biochemicals). Inadequate dietary intake of vitamins and minerals is now widespread, primarily due to excessive intake of high-energy,ARA low-micronutrient, processed foods. In the United States, inadequate intake of vitamins and minerals can lead to chronic metabolic disorders, including mitochondrial damage, DNA (DNA) damage, and chromosome breaks, which can lead to oxidative damage and cellular aging, and ultimately to late-onset diseases (e.g., cancer).DHA This is the "Micronutrient Deficiency Damage Trilogy". The micronutrient deficiencies that trigger this "trilogy" may accelerate cancer, aging, and the central nervous system.β-carotene Therefore, the authors recommend multivitamin-mineral supplementation as a way to ensure lifelong micronutrient dietary recommendations.

For the elderly, they do not need less nutrition than younger people, but their digestive function gradually deteriorates, with a decrease in the secretion of various digestive juices, a decrease in the activity of digestive enzymes, and a decrease in the absorption function of the gastrointestinal tract. In addition, many older people are accompanied by gastrointestinal dyskinesia, resulting in poor appetite and reduced food intake. So on the one hand, the intake of nutrients is reduced, and on the other hand, the absorption of nutrients is weakened. If we don't pay attention to the supplementation of nutrients, nutrients will not be enough to make ends meet, which will eventually lead to a variety of nutrient deficiencies and chronic diseases. If the elderly are taking some drugs, such as aspirin, cholestyramine, etc., interfere with the absorption and utilization of nutrients, it is even worse.

According to the survey results, the proportion of elderly people over 60 years of age using nutritional supplements in China is only 8.5%, which is far lower than that of developed countries in Europe and America. Therefore, nutritionists call for: in promoting nutritional balance at the same time, a rational diet, through the rational use of vitamins and minerals, can improve the nutritional status, prevention of chronic diseases, and promote health.

When purchasing vitamin and mineral supplements for the elderly, special attention should be paid to whether the formula is customized for the elderly, and whether it is fortified with nutrients that are particularly important to the elderly, such as vitamins A, E, B6, B12, calcium, chromium, potassium and so on. Numerous studies have shown that taking multivitamin and mineral supplements can be effective in lowering blood pressure, reducing the risk of coronary heart disease, and preventing ischemic strokes in elderly patients, as well as increasing immunity and preventing infectious diseases.
