Why do we need vitamins?

Answer 1

To be succinct, vitamins are required as cofactors for many proteins involved in vital biochemical reactions and processes. Thus, without the vitamins, these processes become deficient, and are deleterious to the individual.

Answer 2

We get most vitamins from food. If the food we eat does not contain all the vitamins we need, we will probably develop a number of disorders. Scientists have discovered 13 different vitamins.

Good, well-balanced nutrition is important for maintaining good health. Vitamins are essential for our health.

We get most vitamins from food. If the food we eat does not contain all the vitamins we need, we will probably develop a number of disorders.

Scientists have discovered 13 different vitamins: A, B group, C, D, E, D and K.

Vitamin A prevents skin from drying out and helps us see better in the dark. We can find it in fish liver oil, the yellow part of eggs, carrots.

Vitamin B-1 helps the heart and nervous system work properly. Without it we could not grow. It is found in nuts, meat, green vegetables.
Vitamin B-3 prevents a disease called pellagra. We can take this vitamin from meat, fish, cereals, dried beans, nuts.
Vitamin B-12 prevents anemia. Good sources of vitamin B-12 are eggs, meat, and milk products.

Vitamin C is necessary for strong bones and teeth and for healthy blood vessels. It also helps to heal wounds faster. Food rich in vitamin C includes citrus fruits, tomatoes and raw cabbage.

Vitamin K is needed for the coagulation of blood. It is produced by our body but we can also find it in pork, cabbage or spinach.

The vitamins are very important for the human body, because without them we are going to be very weak.

If you don't eat many vegetables, nuts, fruits, eggs, fish etc. you will not only lose your weight but your health.

Answer 3

First of all, what are vitamins? They are substances which are necessary to life, and they are produced by various plants and animals. Everybody must have these vitamins in their diet regularly to enable the body cells to grow and repair themselves. Although scientists have long and complicated names for vitamins, we know them best by their simple letters, A, B, C, D, E, and so on, and each one performs a vital job. Vitamin A, for example, helps prevent infection, and Vitamin C presents scurvy, a distance which makes the body's bones weak and the teeth loose.

Vitamin D is especially important for growing children as it makes their bones strong. If we have a good balanced diet, the chances are that we are getting all the vitamins we need..

Answer 4

First of all, the definition of 'vitamin' is any complex chemical which our bodies need to function normally which our bodies cannot manufacture out of carbohydrates, fats, and amino acids. Apparently, vitamin D does not fit this definition as we can manufacture it if exposed to enough UV radiation. These complex chemicals are required in various functions. Someone mentioned vitamin K. It is a simple example. It is necessary for blood to coagulate. The drug coumadin interferes with vitamin K and therefore is given as a blood thinner. If someone is given too much coumadin they will bleed to death. Folic acid (one of the B vitamins) is necessary for the body to be able to manufacture one of the nucleic acids which make up the DNA in our genes. Some of the vitamins are necessary for a number of different functions. Exactly how vitamin A exerts its effects is not fully elucidated, except how it works to permit night vision.

Answer 5

Vitamins are nutrients required in tiny amounts for essential metabolic reactions in the body. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but that are not essential for life.

the absence of various vitamins in our body causes vitamin-deficiency diseases like beri-beri,pellagra,rickets,scurvy...etc.

Answer 6

vitamins are chemicals that we need for our cells' chemical reactions, but we cannot produce ourselves. to give a specific example, vitamin k is used to help modify proteins involved in blood clotting. without these modifications, these proteins don't work and people without vitamin k cannot clot blood when they begin to bleed.

Answer 7

Biological significance of vitamins

Vitamin A is most effective when taken with vitamin group B (complex), D, E; it is also enhanced by such mineral elements as calcium, phosphorus and zinc.

A

Improves eyesight, stimulates immunity, promotes the healing and renewal of the skin, protects the liver.

B1

Regulates carbohydrate ex and water balance, reduces the need for insulin and reinforces it an obstacle to the development of arteriosclerosis.

B2

Affects metabolism and stimulates growth of the organism and tissue healing, maintains normal eyesight.

B6

Regulates the nervous system, factor in the ex of amino acids, carbohydrates and fats, the reduction increases the heart muscle.

B12

It affects the liver and the nervous system, is intensifying blood clotting.

C

Participates in the ex of carbohydrates, improves resistance to infection increases blood clotting.

D

Regulates phosphor-calcium metabolism, helped mineralization and strengthen bones.

E

Affects protein and fat metabolism, defends the body when there is a lack of oxygen.

F

Improves healing skin and mucous membranes obstacle to the development of arteriosclerosis.

PP

Participates in carbohydrate and albumin metabolism, beneficial to the heart muscle, improves liver function.

Remember this:

Vitamins Group B very well combined with vitamin C. Its effects on the human body also increases the combination with magnesium;

Vitamin C is absorbed better if it is to take such mineral elements as calcium, and magnesium;

Vitamin D is absorbed better with vitamins A, C, as well as calcium and phosphorus.

What prevents the body absorb vitamins:

It should be borne in mind that some medications prevent assimilation of vitamins and remove the human body valuable nutrients.

The same can be said about some of the harmful habits.

For example:

Alcohol destroys vitamins A, Group B, as well as calcium, zinc, potassium, magnesium and iron;

Nicotine destroys vitamins A, C, E and selenium;

Caffeine destroys vitamins Group B, RR, as well as reduces the content of iron, potassium, zinc, calcium;

Aspirin reduces the content of vitamins B, C, E, as well as calcium and potassium;

Hypnotics (sleep pills) more assimilate vitamins A, D, E, B12, as well as substantially reduce the level of calcium;

Antibiotics destroy vitamins Group B, as well as iron, calcium, magnesium;

Diuretics withdrawing the body of vitamins B, as well as magnesium, zinc and potassium;

Laxatives (purgative) prevent absorption of vitamins A, D and E.


How to keep vitamins

Wash salad only under running water;
Boil potatoes in the skin and the best way for a couple;
Buy only fresh fruits and vegetables;
Keep fruits and vegetables a short time and always in the cold and dark room;
Clean vegetables immediately before use;
Boil vegetables in a microwave oven or a pressure cooker.
Eat and realax!

The diet that will be products with a high content of some of the major components, that impede a stress or relieve nervous tension.

Vitamin B1 - reduced depression and prevent signs of increasing concern;

Vitamin C is necessary to fight against a stress;

Vitamin E - is actively involved in the supply of oxygen to the brain;

Folic acid, its lack of leads brain disorders;

Zinc is the normal functioning of the brain;

Magnesium - antagonize stress;

Calcium - relaxes, removes stress.

Glycosylated forms of pyridoxine, vitamin D, niacin, pantothenate, and riboflavin exist in nature, whereas glycosides of retinol and ascorbic acid are products of in vitro transglycosidation. β-Glucosides of pyridoxine (a) are prevalent in plant-derived foods, (b) contribute to human nutrition as partially available sources of vitamin B6, (c) undergo partial hydrolysis by a novel mammalian cytosolic β-glucosidase, and (d) exert a weak antagonistic effect on the utilization of free pyridoxine. Niacin exists in grains as complexed forms with low bioavailability, whereas vitamin D glycosides are toxic components of certain calcinogenic plants of importance in animal health. Glycosides of pantothenate and riboflavin appear to be minor products of mammalian metabolism. Glycosylation of retinol or other hydrophobic alcohols may facilitate glycolipid turnover, whereas a stable ascorbyl glucoside may have nutritional applications. Glycosylation of vitamins exerts widely ranging chemical and biological effects, with great nutritional and metabolic significance.

Answer 8

as a supplement. especially if our diet doesn't suffice the nutrients needed by our body. but if you think you have a good diet. i don't think you need a dose. natural way is always better than synthetically prepared. there! hope i helped you.

Answer 9

We dont need the pill form if you eat well.

Answer 10

to digest foods and to live
