In combination with a normal diet, dietary supplements are concentrated sources of nutrients (or other substances) with a nutritional or physiological effect. They may be marketed for example in the form of pills, capsules, tablets, capsules, liquids, etc.
The aim of harmonizing the rules on these products is to protect consumers against potential health risks and to ensure that food supplements are not a source of misleading information. With regard to the safety of food supplements, Directive 2002/46 / EC of the European Parliament, transposed by the decree of 20 March 2006,governs the manufacture and marketing of food supplements.
Definition of the food compliment
Food supplements are defined as food products that complement a traditional diet. Nutrients, such as vitamins and minerals, are much more effective when they come from food sources. However, it is sometimes difficult to have a balanced diet on a regular basis, especially if there are special dietary considerations to consider such as allergies that make some items unmanageable.
Dietary supplements, also known as dietary supplements, can help get the nutrients that are missing from a normal diet. However, they are not meant to replace meals and snacks. It is necessary to contact a doctor or dietician before taking any dietary supplements.
Multivitamins are the most used ingredients in dietary supplements. These include vitamins A, complex B, C and E, as well as important minerals such as zinc and iron. Some dietary supplements are even recommended at certain stages of life. For example, a doctor may recommend a folic acid supplement for pregnant women, or a combination of calcium-vitamin D for the elderly. For example, older people with fragile bones can absorb the nutrients they need, especially if they are facing unbalanced nutrition for a variety of reasons.
Corrective food supplements of the diet
In general, children and adults can benefit from taking a daily multivitamin in the form of food supplements. This dietary supplement helps provide a constant source of necessary vitamins and trace elements. According to the Harvard School of Public Health, a daily multivitamin, and perhaps a vitamin D supplement, is a great way to ensure you get all the nutrients you need to be healthy. However, the first consideration is to eat a healthy, diverse and balanced diet. Even the best dietary supplement can not replace good nutrition. In many Western countries, people tend to consume foods that are high in calories, but lack the nutrients that are essential for good health.
Generally, you do not need to take dietary supplements if you are healthy and if you eat balanced. This means a diet that is varied: foods rich in starch (preferably whole grain), fruits and vegetables, dairy products, lean meat, fish … Excessive intake of food supplements can be harmful and cause unwanted side effects .
Other major categories of dietary supplements
Some types of dietary supplements include antioxidants, vitamins, lipids, minerals, and proteins. Recommended dietary supplements may vary depending on a person’s dietary deficiencies. Supplements are sometimes added to a person’s diet because of certain activities in which they participate. For example, athletes often need more carbohydrates in their diet because carbohydrates can increase energy.
In Western cultures, diets are usually high in carbohydrates. In the body, chemical processes break down carbohydrates into glucose. If the body does not maintain a healthy level of glucose, diabetes can develop.
Those who want to avoid colds and other flu viruses often turn to certain types of dietary supplements, such as antioxidants. Antioxidants are usually made up of plant extracts. These extracts enter the bloodstream and cleanse free radicals. Free radicals are unstable compounds that, in an effort to become stable, try to steal electrons from other molecules. As a result, free radicals can cause diseases and cell damage.
Good fats, also known as fatty acids, are also often deficient in some people: food supplements fill this gap. These fats are found in animal products, nuts, seeds and plants. Docosahexaenoic acid (DHA) and eichosapentaenoic acid (EPA) are two examples of beneficial fatty acids. Specifically, DHA and EPA are very important for nerves and brain function.
Minerals are often considered to be among the most important of the different types of dietary supplements. They consist mainly of inorganic compounds and metals. Healthy bones and teeth are usually attributed to a good amount of minerals in the diet.
Proteins are used to develop muscles and tissues. Healthy hair and nails are two physical indicators that a person draws enough protein in their diet. Before you can find dietary supplements that contain protein, you can already find protein in foods such as beef, fish, eggs, dairy products, seeds, nuts and legumes.
