Vitamins why does vitamin deficiency occur
Vitamin deficiency is often mentioned in commercials. Why do we need vitamins? It’s difficult to figure out according to one’s health which vitamins need to be taken in addition. Only medical tests can define vitamin deficiency or an excess of vitamins in the human body.
The World Health Organization considers 70% of a person’s health to depend on eating healthy. Eating healthy doesn’t only include foods that present an energetic value, but also foods that contain vitamins that are active in the metabolism.
Metabolism consists of 2 parallel processes, operating in the body during all of a person’s life.
1. Synthesis of new substances from food, which are necessary for normal vital activity.
2. Decomposition of substances supplied to the body through food.
The ideal outcome is the balance between these processes. They are operating with the involvement of vitamins. Vitamin deficiency leads towards the malfunction in metabolism and formation of ferments.
There are water-soluble and liposoluble vitamins
Water-soluble vitamins are those, digested by the body in the presence of water. They don’t accumulate in the organism and must be supplied with food daily. These are vitamins C, group B: В1, В2, В3, В5, В6, В9, В12; biotin, folic acid, and pantothenic acid. Plants are the main source of water-soluble vitamins.
Liposoluble vitamins: А, D, Е, К are soluble in fats. These vitamins accumulate in the liver and fatty tissues. When required, liposoluble vitamins get into the blood stream and are used by the body.
Vitamins are needed by the body in little quantities for biochemical reactions. Even a slight vitamin deficiency causes health aggravation.
Causes of vitamin deficiency in the organism
1. Irrational eating. Monotonous eating causes vitamin deficiency.
2. Failures in the transportation and absorption of vitamins. Transportation of vitamins and their absorption depend on the condition of the digestive tract. The process of absorption mainly occurs in the small intestine. Normal function of the pancreas, liver, and healthy intestine walls are needed for that. If a person has problems with their digestive tract, vitamin deficiency may occur.
3. Malfunction of the synthesis of vitamin combinations, which participate in metabolism. The formation of ferment molecules is unbalanced due to certain diseases of endocrine glands, for example, pancreas. These are molecules, which function in the body due to chemical reactions with vitamins. Ferments participate in all the processes, completing chemical reactions in no time and turning certain substances, into others, which are necessary for cell nutrition. Malfunction of the formation of ferment occurs when we consume toxic foods, undergo stress, suffer from hereditary diseases, etc.
4. The action of antivitamins, which oppose vitamins. There are antagonists, neutralizing the action of vitamins. Such substances are found in uncooked products. Interacting with vitamins, they decompose them into the substances that are useless for the body and cause vitamin deficiency.
Folic acid, for example, participates in protein synthesis and activates blood formation. Its chemical counterpart doesn’t possess the same properties, but it slows the development of cells, including cancerous ones.
Vitamin B1 is neutralized by the substance, contained in uncooked fish, bilberries. In a small amount, it is found in rice, cherries, spinach, etc. Antivitamin of vitamin C is found in many vegetables, such as pumpkin, vegetable marrow, and cucumbers. Vegetable storage and crumbling makes vitamin C decompose fast due to the antivitamin action.
Products from uncooked soy beans, haricot or with corn oil destroys vitamins, Е, and D. Why aren’t raw eggs recommended for eating? There’s a biotin antagonist found in them, which is destroyed with thermal processing.
Those, who like brown rice, soy beans, and mushrooms should know that niacin’s (vitamin PP) antivitamin is found in these products.
Many raw food eaters are subject to vitamin deficiencyto a greater degree than those who consumed cooked foods.
Consumption of coffee in large amounts may also cause vitamin deficiency. The role of coffee in neutralizing of some vitamins has been proven. Unfortunately, even with heating, coffee’s antivitamin quality isn’t eliminated.
Antivitamins have found their application in health improvement despite their function of vitamin destruction. Some diseases may be cured with their help. A doctor, prescribing such medicine, always prescribes vitamins as well to prevent vitamin deficiency.
