Vitamin Discovery Historyi

For a long time, people did not know which vitamins are useful and which ones can be dispensed with. Unlike fatty acids, amino acids and carbohydrates, vitamins are not of energy value for the body, but at the same time they contribute to the normalization of metabolism in tissues and cells. The main ways to get the vitamins you need are sunbathing, taking food and certain supplements.

Vitamins are substances that have a certain effect on the human body. They are taken internally with food or special additives. So, vitamins belonging to group B contribute to the proper functioning of the nervous and immune systems, cell renewal. However, if the food is not saturated with vitamins, they are obtained from the outside, from special supplements.

Vitamins were not discovered by chance - scientists were trying to find a way to salvation, since many people suffered from dangerous diseases due to unbalanced nutrition. Dr. J. Lind became famous for his experiments on people, however, he did them in the hope of solving the problem. On the ship on which Lind was sailing, there was a powerful epidemic of a dangerous disease - scurvy. Lind conducted a study - he divided all the sick sailors into two groups and began to feed them with different foods, giving one group cider, another vinegar, and the third citrus. Those sailors who ate citrus fruits were the only survivors.

However, another scientist, Nikolai Lunin, first thought about vitamins. It was he who singled them out as food elements. It is interesting that at that time the doctor's hypothesis about vitamins was not taken seriously by the scientific community at all. Despite the fact that at that time vitamins did not yet have their modern name, Lunin proved that they should be included in the human diet and are ingested with certain foods. Studies have been done in mice. The experiment was simple - the mice were fed artificial and natural milk. Those who received artificial substances died quickly. So Lunin concluded that natural milk, in addition to nutrients, contains other elements useful for the body.

The benefits of vitamins for humans2

What vitamins are good for the body? First of all, these are natural, not synthetic vitamins. The benefits are as follows:

  • preventing the occurrence of certain diseases;
  • lowering cholesterol levels;
  • prevention of skin diseases;
  • stabilization and improvement of the work of some organs.

Vitamins are consumed in different forms - through foods, in tablets, dietary supplements. If the usual daily diet does not include a large amount of natural products, in order to avoid a deficiency of vitamins important for a person, they should be taken additionally, in tablets.

There are also multivitamins - supplements that help improve the balance of vitamins in the body.

Each separate type of vitamins has a specific effect on the body:

Retinol - Vitamin A - very important for skin and eyes. Promotes wound healing, elimination of some infections, improves hair condition.

Thiamin - Vitamin B - prevents serious heart disease and the development of vitamin deficiency. Promotes brain development, improves blood circulation. This vitamin is especially important for the elderly.

Riboflavin - Vitamin B2 - helps to increase the metabolic activity of the human body, prevents the development of cataracts.

Vitamin D - treats diabetes, rickets, arthritis, restores blood pressure.

Vitamin K is very important in preventing the development of internal bleeding in the body. Reduces menstrual pain. Improves the functioning of the cells of the nervous system.

Thus, vitamins are of great benefit to the body - they prevent the development of serious, life-threatening diseases, and contribute to the restoration of certain types of cells. While there are various pills and supplements available, it is recommended that you get the major groups of vitamins with natural foods as they are most beneficial in their natural, non-synthetic form.

Are vitamins harmful?

Before using dietary supplements, you need to find out which vitamins are useful and which ones can cause serious harm to the body. So, natural vitamin A does not exist in the form of tablets, pharmacists have learned only to synthesize a separate element - beta - carotene. This compound is extremely necessary for the eyes, however, if it is used often and thoughtlessly, it can get extremely negative consequences - the likelihood of developing intestinal cancer increases. If a person also smokes, the risk of developing heart disease increases.

Even with an excess of natural vitamin A, adverse effects can occur - dizziness, nausea, therefore, any type of supplement should be used with extreme caution.

Vitamin C is also not as simple as it seems. People used to call it "ascorbic acid" and swallow it like candy, however, vitamin C contains various elements, an overdose of which contributes to the development of atherosclerosis and even increases the likelihood of a person's premature death.

Vitamin D is formed in the human body under the influence of sunlight. An excess of this vitamin is very dangerous for children, since the skull stops growing, while the brain increases in size, which causes extremely unpleasant consequences.

What vitamins are needed4

In order for the human body to work properly, a certain amount of vitamins must be supplied to it daily along with food. Vitamins A, B, C, K, and D are essential for health.

If a person does not consume natural products, but eats only canned food, after a while the body makes itself felt. There is a constant feeling of hunger even with regular consumption of food. In the cold season, be sure to eat foods containing vitamin C - these are roots: carrots, celery, beets - they can be found in any store.

In the case when the diet is not balanced, a lack of vitamins necessarily occurs. You can minimize it by adding natural products and excluding rice and flour, which are, in fact, "dummies".

Is an excess of vitamins dangerous? 6

An excess of vitamins can be more dangerous than a lack of them. Due to the large number of certain elements, the work of the heart, lungs, brain, and hematopoietic organs is disrupted.

The general well-being of a person is disturbed, symptoms such as nausea, weakness, emptiness, headache and dizziness, vomiting, pallor of the skin appear. All these signs indicate a severe poisoning, which does not occur immediately, but gradually, with constant intake of vitamins in increased doses.

Additional signs of poisoning are tremors throughout the body, chills, indigestion, dehydration, and edema. If a person detects at least one of these signs, you should immediately consult a doctor, especially if you have taken vitamin preparations.

Vitamin poisoning does not occur overnight, most often the body is exposed to them for a long time. It is not easy to diagnose such conditions, an excess of vitamins is noticeable only during tests. Lung cancer can be triggered in smokers who abuse vitamin C intake.

An excess of vitamins is a disease (hypervitaminosis) that requires serious treatment. The doctor selects a special diet that excludes the consumption of this substance for a certain time.

Scientists' opinion on vitamins7

Modern scientists regularly conduct research, during which new facts about minerals and biological additives are revealed. It has been proven that taking some vitamins and minerals supplements can cause serious harm to the body. The studies were conducted at the University of Birmingham Medical Department.

A lot of work has been done to collect all known data on each vitamin and mineral. According to the results of this study, a person does not need additional supplements if they have a balanced diet that includes fruits, vegetables, legumes and other types of foods.

At the same time, doctors do not talk about completely eliminating synthetic vitamins. It is only a matter of taking them deliberately, on the recommendation of a doctor. Thus, the doctor - the scientist who conducted the research, noted that "the intake of folic acid by pregnant women is very important." Also, on the recommendation of a doctor, it is necessary to take vitamin D if it is found to be lacking in the body.

Iron preparations must be taken by women who, due to biological characteristics, lose a large amount of blood during menstruation.

Three in One: What is a Multivitamin8

Medical professionals are not categorically “against” taking vitamins, but they warn people about the possible negative consequences in case of thoughtless intake in the absence of recommendations.

A multivitamin is a complex of common vitamins, selected to achieve a specific effect. The danger lies in the fact that if they are incorrectly selected, there may be a lack of some vitamins and an overabundance of others.

Vitamin E by itself does not pose any danger, however, if you take it in a multivitamin complex, and at the same time consume food containing natural vitamin E, you can provoke the development of cancer, since the daily dose is exceeded 18 times. If the overall diet is balanced, there is no need to take a multivitamin complex, it is better to pick up some synthetic elements separately.

Lack of vitamins in the body9

Lack of trace elements - vitamin deficiency, also causes great harm to the body. The disease develops with malnutrition. The most obvious signs of vitamin deficiency are nausea, dizziness, and sometimes even headaches.

There are certain types of diseases caused by a lack of any vitamin: scurvy (C), night blindness (A), rickets (D), beriberi (B1), pellagra (PP).

Treatment of vitamin deficiency can only be selected by a doctor, since dietary supplements need to be drunk only in strictly recommended doses, without exceeding them.

Sailors and scurvy10

Before the vitamins were discovered, many seafarers on sea voyages died a horrible death from scurvy. In the days of seafarers, this disease was considered one of the most dangerous, because no one knew how to deal with it. According to historical data, scurvy in the era of geographical discoveries claimed the lives of at least a million sailors. In the Vasco de Gama team alone, almost all members of the large team of 160 people died. Then no one could have thought that it was just a shortage of oranges on board.

Following the example of James Lind, J. Cook set out on a voyage, filling the holds with sauerkraut, and surprisingly returned from a trip with a full crew. So, in 1795, an insidious disease was discovered, and lemons, oranges, cabbage, and vegetable products began to be included in the mandatory diet of all sailors.

Without a doubt, with the correct intake of foods containing vitamins, you can avoid the development of serious diseases, and therefore increase life expectancy. However, it is impossible to live by eating only synthetic supplements with vitamins.

In hospitals, doctors are nursing seriously ill people by feeding them through a tube with a mixture of vitamins, however, this is only a temporary solution. Despite the fact that a person receives all the necessary elements, they are not always absorbed by the body, and life expectancy only decreases. To prolong life, you need to undergo a full medical examination, detecting serious diseases in time. In addition, you need a balanced diet containing all vitamins and minerals.
