Dietary supplements are products that help people supplement nutrients and beneficial ingredients, usually containing vitamins, minerals, amino acids and fatty acids. Food without residue is the core value of dietary supplements. Proper selective intake can directly supplement the needs of the human body, improve sub-health and prevent the occurrence of diseases.
Under ideal circumstances, we do not need dietary supplements.
We can get enough sunshine and we can eat vegetables grown in fertile soil.
Our beef comes from cattle that grow up grazing in the fields, and the chickens we eat are also roaming chickens. We can also eat wild fish.
We do not suffer from fertilizers, pesticides or hormones, nor do we abuse antibiotics.
We do not have much work pressure, and we do not often sit in office.
Why supplement dietary supplements?
A single diet structure
Research has consistently shown that human beings need health elements more than ever because of environmental pollution and declining land quality.
In addition, the human body needs to intake more than 40 nutrients a day, and nowadays a single dietary structure has been difficult to meet the normal nutritional needs of the human body.
Decline in fruit and vegetable quality
Vitamins can usually be obtained from fruits and vegetables. But modern agriculture uses a large number of artificial fertilizers and pesticides, so that a large number of nutrients in the soil loss and irreparable, resulting in insufficient vitamin content in plants.
Moreover, the drop in nutrient content in fruits and vegetables is amazing. The vitamin C content in an orange can drop from 180 mg to an average of 60 mg, and even in some supermarket oranges there is no vitamin C at all!
Hazards of refined food
Food processing is the main cause of vitamin loss. After processing, wheat and rice lost more than 70% trace elements.
Every stage of food processing - boiling, baking, frying, freezing, thawing - consumes the nutrients.
Taking all these factors into account, the nutrients we eat from food are losing step by step.
Dietary supplements can regulate the nutritional balance in the body and improve the nutritional deficiencies, such as sub-health and invisible hunger, which are threatening human beings.
Different populations lack nutrients.
Over 65 years old: it is easy to lack vitamin B12, vitamin D, vitamin K, folic acid, calcium, zinc and other nutrients.
Children: Due to the preference for junk food and eating habits, preschool children generally lack vitamin D and B vitamins in their diet. In addition, about 5% of children suffer from iron deficiency anemia.
Pregnant women: they are prone to lack of folic acid and iron.
Female: easy to lack magnesium, iron, zinc, folic acid and calcium.
Male: Because of frequent smoking and drinking, most men lack vitamin A, vitamin C, B vitamins.
So here comes the question...
How should we replenish it?
What nutrients do you lack in your body?
Try to get nourishment from natural foods.
We have evolved with nature for millions of years, and long-term natural selection has made natural foods more suitable for us.
Many nutrients need enzymes, minerals and some cofactors to absorb them well. These substances are found naturally in foods, and synergistic compounds are often lacking in synthetic vitamins.
Food is a natural gift, and its composition and proportions are so subtle that it is hard to imagine. One nutrient may promote the absorption of another, or inhibit the activity of another, and these complex interactions make them much more effective than dietary supplements.
For example, eating broccoli can reduce free radical levels, and broccoli in a variety of nutrients separated, in the form of dietary supplements taken together, but not the same effect.
As long as conditions permit, we should try our best to get our nutriment through real food. Eating on a gluten free 2 food list can help you optimize your nutrition from food.
Choosing the right dietary supplement
The human body has different absorption rates for different forms of nutrients. Choosing the right form of nutrients can ensure the effectiveness of the dose. In addition, some forms of nutrients are harmful to the human body.
For example, L-methionine zinc, carnosine zinc, glycine zinc are easily absorbed by the human body in the form of zinc, and zinc oxide (zinc oxide) is difficult to absorb, zinc aspartate (zinc aspartate) even has neurotoxicity. Vitamin K2 has the form of MK-4, MK-7 and so on. The half-life of the MK-4 is very short, only an hour, so it's not easy for the human body to use; and the half-life of the MK-7 is three days, which ensures that your body has a better chance to use it.
It's best to know the difference between different forms of nutrients, but one form of nutrient tends to be dazzling and numerous. To make choices easy, we can master one principle: choose the form of nutrients found in natural foods.
The nutrients produced by industry often have completely different biochemical reactions with natural nutrients. Folic acid, for example, can also prevent neural tube defects in infants, but some studies have shown that artificial folic acid increases the risk of cancer, and natural folate does not. Synthetic vitamins are basically folic acid, because they are cheaper.
For example, trans fats from ruminants are good for health, while trans fats from refining vegetable oils are toxic to humans.
Choosing the natural form of nutrients in food is often the simplest and wisest way.
Choosing dietary supplements carefully
In fact, the dietary supplement industry is very irregular. China naturally does not need to say that there are many problems in the United States. Unlike food, dietary supplements have not been tested before they go on the market, and the FDA will only investigate the manufacturers who have problems.
Therefore, as consumers, we need to grasp some basic principles to avoid those counterfeit goods.
Judge with common sense, and do not buy products that are healthy with divine medicine.
Try to buy ingredients with a single product and avoid mixtures that do not indicate the proportions of various ingredients.
Try to buy products with less stuffing, choose powder or capsule to avoid tablet preparation.
Use Google search, brand name + "fraud" or "FOD" to see if the manufacturer has had any problems.
For products that claim to be supported by clinical trials, the name of PubMed is searched.
Dietary supplements tested by third parties are often more reliable, including Consumer Labs, NSF International, USP Dietary Supplement Verification Program, Informed Choice verification, Banned Substances Control Group, etc.
High quality dietary supplements are generally more expensive, but paying for quality is cost-effective.
Dietary supplements are effective in many cases, but they are just "supplements" and far from being a substitute for healthy meals. We should use dietary supplements as a tool for optimizing health, and it would be unwise to deify them or ignore them altogether.
