Vitamins are very important for the human body to function properly. They are very important for the normal growth as well as for the essential organ development. It is very important for a person to consume varied diet to get all the essential vitamins to avoid deadly diseases and illnesses.Each vitamin and mineral should be taken first through diet then supplementation making sure of proper intake range.Higher intake may also cause damage as vitamin deficiency and be very harmful. Some of the essential vitamins are vitamin A, B1, B2, B6, B12, C, D, E, and K.
Vitamins are normally divided into fat-soluble vitamins and water-soluble vitamins. Fat-soluble ones are stored in the body’s fat tissue. These are more easily absorbed by the body in the existence of dietary fat. Vitamin A, D, E, and K are fat soluble vitamins whereas vitamin B1, B2, B6, B12, and C are water-soluble vitamins. Water-soluble vitamins body must use right away because any leftover will be disposed of in the urine.Each vitamin has different benefits, and the need for the vitamins vary with the age of a person, health conditions, and gender. Mostly vitamins are found in normal healthy foods and do not require any supplementation.
Vitamin A is very important for the proper vision and also for the production of white blood cells. Also to maintain healthy bones, teeth, and skin. Vitamin B enhances metabolism and energy, offer great protection against birth defects in the pregnant women, and also properly maintains the nervous system. Vitamin C is very important to prevent infection and to protect tissue in the body. It also encourages wound healing.
Vitamin D protects bone whereas vitamin K is very important for the free flow of blood without any clots. Vitamin E protects lungs and provides healthy skin. It is also included in helping the body to produce and form red blood cells. However, a person must take extra care to understand what their body needs and consume vitamins accordingly. Vitamin D is hard to obtain in foods, so it is best to get sunshine regularly.
An enormous and inconceivable amount of money is spent every year in the world on vitamins and supplements to prolong a lifetime as it is believed. But many new studies are giving results proving this is going in totally other direction and taking it may shorten your life.
It is always advisable to take supplements in moderate measure. Excessive in-take of supplementary nutritional products will cause adverse effects. The best way to take-in vitamins is from natural food sources. You must not entirely rely on vitamin supplements.
There are some points to consider when talking about vitamin supplements. Vitamin supplements are processed. This means that a certain amount of chemical reaction is used to make them. Even though the manufacturer may deny it, there is some chemical process involved. Chemicals are not a good thing to have in your body unless they are within certain limits.
Vitamins and minerals if taken in excess will turn toxic. Excessive vitamins are stored in the liver, or be deposited off as fat in the adipose tissue. Over time they accumulate and become toxic.
Too much vitamin A will cause the body to lose its oxygen rapidly. Nausea sets in. Due to lack of oxygen, the skin may go pale. Too much vitamin A intake also causes a lot of overload on the liver, ultimately leading to its damage. It even increases the chance of developing lung cancer among smokers.
Excessive vitamin D intake causes problems in the kidney. Kidney stones are the last thing you want. They are painful depositions of solidified vitamin D. Excessive vitamin D also causes hypertension. It could lead to a heart attack.
Vitamin E is the safest of all of them. That’s because it dissolves in fat. Excessive usage might not cause serious problems. In fact, excessive usage is recommended to prevent heart attacks.
It is very often that multivitamins contain 100 percent and more of your daily value of vitamin C or A, calcium or iron. If you are consuming healthy and nutritional food, there is no need at all for including these in your diet.
So all these are the dark side of vitamins.
Many nutrition experts contend that taking vitamin supplements is not especially helpful. They say that the other socioeconomic factors that tend to accompany vitamin-taking as a habit, such as medium to high incomes, good diets, and regular physical activity, are more significant for maintaining health. However, a recent study shows that vitamin supplements may be helpful for women who are expecting, or at least for their developing child.
As reviewed by The New York Times, a study published in the journal Epidemiology showed that women who reported taking prenatal vitamins were 40% less likely to give birth to children who later developed autism or autism spectrum disorders. The primary author Rebecca Schmidt and her team took blood samples and analyzed the expression of genes associated with the metabolism of folate and found that the women who had folate metabolism genes that were a slight variation from most of the population had seven times higher risk of having a child with autism.
But it is also very important to remember that prenatal vitamins should not be a replacement for a healthy diet.
Usual key nutrients prenatal vitamins contain are calcium, folic acid, iron, zinc, copper and other vitamins like A,E and C.
Folate is a kind of vitamin B that is very important in fetal development. Children conceived in a mother with inadequate folate are more likely to be born with spina bifida, or when the backbone does not close before birth, which can cause a severe disability depending on its extent. A lack of folate has recently been associated with the development of autism, and in the case of this study, it is believed that pre-natal vitamins are providing folate which prevents autism from occurring.
It is advised to take folate from whole high-folate foods. Folate is present as enrichment in many bowls of cereal and is also found in leafy green vegetables, legumes, and organ meats, in addition to prenatal vitamins.Supplements are a just easier way to getting enough of vitamin B9. In this case, it is best to make sure these supplements do not contain folic acid. Folic acid is a synthetic form of vitamin B9 and the human body doesn’t handle it pretty well. There could even appear some negative health effects.
