Vitamins in a diet of pregnant women

The requirement of an organism for fiber, calcium and gland essentially raises during pregnancy whereas the requirement for many vitamins increases slightly. For the majority of women at a healthy food this additional quantity of vitamins arrives with additional food which they eat. Vitamins contain practically in all products and consequently at the balanced and healthy diet deficiency of vitamins at the child is improbable. For this reason - provided that the woman it is high-grade eats - many doctors any more do not appoint multivitamin preparations during pregnancy.

Consume additional quantity of folic acid. It is possible to consider as an exception of this rule folic acid, group vitamin In, very important for correct development of the child. With folic acid such products, as fresh sheet vegetables, beans, nuts, a liver, kidneys, dark green fruit and vegetables, a broccoli are rich. During pregnancy the requirement for folic acid at least doubles. As this vitamin does not collect in an organism, and during pregnancy of a kidney allocate it even more intensively, your daily norm of its consumption makes from 400 to 800 micrograms. With a lack of folic acid connect developmental anomalies of the central nervous system of the child, and especially a backbone crevice. Researches have shown, that at the women accepting from 100 to 4000 micrograms of folic acid in first 6-12 weeks of pregnancy, considerably lowered risk of a birth of children with defects of a spinal cord is marked. Last works of scientists have allowed to assume, that the requirement for folic acid is defined at genetic level. Probably, some women are genetically predisposed to deficiency of folic acid and it during pregnancy food additives containing these substance or vitamins are required. It is impossible to define in advance, whether you concern this category or not and consequently all women should receive enough of folic acid at the very beginning of pregnancy - the developments mentioned above anomaly appear in the first some weeks. It is even better, if you start to accept preparations with folic acid for some months prior to the beginning of pregnancy. Management under the control over products and medicines of the USA recommended, that since 1998 in all vitaminized products, including a wheaten and corn flour, macaroni and rice, folic acid was added. This additive cannot satisfy daily requirement of the pregnant woman and consequently special preparations have not lost the value. Risk of development of anomalies of a spinal cord Because of a lack of folic acid above all in the first months of pregnancy but to accept preparations with this vitamin follows throughout all term. The newest researches have shown, that the lack of folic acid on all extent of pregnancy increases probability of a birth of the sick child. pregnancy symptoms

Be careful of overdose of vitamins during pregnancy. We have well enough studied average day requirement for various vitamins during pregnancy, and also avitaminosis consequences, but all of us know about influence of overdose which can go to harm yet to the not born baby more few. Surplus of vitamins A, D and Е connect with various developmental anomalies of newborns, and also with warm illnesses of mother. For example, the researches spent in 1995 have shown, that at pregnant women who accepted daily more than 10 000 units of vitamin A, the risk of a birth of the child with a harelip, the wolf mouth or a heart disease five times raised. The organism protects itself from surplus of nutrients (and especially water-soluble vitamins), however superfluous quantity of vitamins A, D and Е automatically is not deduced from an organism as they are fat-soluble and collect in a fatty fabric. In it is considered to be the big doses of vitamin C and group vitamins harmless as these vitamins are water-soluble and their surplus is easily deduced from an organism. Nevertheless the newest researches have insinuated safety of overdose and these substances. Newborns, whose mothers accepted very big doses of vitamin C, can be born with the generated dependence on this vitamin, and in the first days after a birth at them avitaminosis signs develop. At some babies, whose mothers during pregnancy abused vitamin В6, spasms can be observed. Results of these researches push to a following conclusion: it is necessary to adhere to a dose appointed your doctor, - it is no more and not less. And to watch all pregnancy symptoms.
