Vitamins are organic compounds that are sufficient in very small amounts for the activities of our cells, but can cause some problems in their deficiencies. Since they are either not produced at all in our body or cannot be produced in sufficient quantities, they must be provided externally through food. They are necessary for healthy body development, digestive functions, and the immune system's ability to fight infections. They also enable the use of proteins, fats and carbohydrates. Vitamins are not burned in the body, that is, energy (calories) is not taken from vitamins.
It is true that we need vitamins for the normal functioning of the body. However, vitamins are not sources of energy. They are nutrients taken from the foods we eat. A proper and healthy diet meets the body's vitamin needs.
Nowadays, most people use additional vitamins, thinking that their bodies do not receive vitamins despite having a balanced and adequate diet. However, in people with a healthy diet, taking high doses of additional vitamins is useless and dangerous. In addition, a vitamin Excessive intake may adversely affect the function of another vitamin. For example, high doses of vitamin E may lead to vitamin K deficiency, causing bleeding.
Some problems that may occur in our body due to excessive intake of vitamins are due to the fact that some of these compounds are fat-soluble. Fat-soluble vitamins. They are vitamins A, D, E and K. These vitamins, which are resistant to cooking, are absorbed by fats, excreted through the lymph circulation and stored in the liver when taken in excess. Fish, butter, eggs, milk, cheese, carrots, leafy vegetables, tomatoes, apricots, bananas and potatoes contain vitamin A. Little or no fat in the diet causes deficiency of these vitamins.
While excess of vitamin A causes blurred vision, liver disorders, bone diseases and an increase in the risk of lung cancer, its deficiency increases the risk of infection and the occurrence of some eye diseases.

Water-soluble vitamins are B (B1, B2, B3, B5, B6, B7 (biotin), folic acid, choline, B12) and C. These vitamins are degraded by cooking.
Accumulation of vitamins B and C in the body is very rare. They are excreted through urine and the need is high because their storage is low. Vitamin B deficiency is especially common. Symptoms of vitamin B deficiencies other than vitamin B12 sometimes appear in a few days. Vitamin B12 storage It is enough for a person for more than a year. The symptoms of vitamin C deficiency appear in a few weeks.
B group vitamins are found in grains, nuts, legumes, milk, eggs, cheese, liver, meat and green vegetables. In their deficiency, the incidence of blood diseases (anemia) and some neurological diseases increases. Foods rich in vitamin C are fresh fruits and vegetables, especially citrus fruits, kiwis and strawberries. Vitamin C is a powerful antioxidant and plays a role in the functioning of the immune system. Its deficiency causes scurvy disease, and its excess causes scurvy disease.
