Vitamin C Is A Water-soluble Vitamin

Vitamin C - a powerful antioxidant. It plays an important role in the regulation of redox processes involved in the synthesis of collagen and procollagen, the exchange of folic acid and iron, as well as the synthesis of steroid hormones and catecholamines. Ascorbic acid also regulates blood clotting, and normalizes capillary permeability, is required for hematopoiesis, anti-inflammatory and anti-allergic action.

Vitamin C is a factor in protecting the body from the effects of stress. Intensifies reparative processes, increases resistance to infections. Reduces the effects of different allergens. There are many theoretical and experimental prerequisites for the use of vitamin C to prevent cancer. It is known that in cancer patients due to the depletion of its reserves in tissues often develop symptoms of vitamin A deficiency that requires further their introduction.

There are data showing the preventive role of vitamin C against colon cancer, esophagus, bladder, and endometrial.

Vitamin C improves the body's ability to absorb calcium and iron, remove toxic copper, lead and mercury.

Importantly, in the presence of adequate amounts of vitamin C significantly increases the stability of vitamins B1, B2, A, E, pantothenic and folic acids. Vitamin C protects LDL cholesterol from oxidation and, consequently, the vascular walls of the deposition of oxidized forms of cholesterol.

Ability to successfully cope with the emotional and physical burden of stress is more dependent on vitamin C than any other vitamin. Adrenal glands that secrete hormones necessary to act in stressful situations, contain more of ascorbic acid than any other body part. Vitamin C helps the development of these stress hormones and protects the body from toxins produced during their metabolism.

Our body cannot store vitamin C, so you should always replenish it. Since it is water soluble and exposed to temperature, cooking with heat treatment destroys it.

Vitamin A Deficiency Symptoms

It is important to recognize vitamin A deficiency symptoms since vitamin A is so essential to the body. This particular mineral plays an important role in many body functions such as bone growth, cell diffusion, cell division, reproduction and vision. It also helps to regulate the immune system to keep away infections. When the body does not get enough vitamin A, it becomes susceptible to bacteria and viruses.

There are several vitamin A deficiency symptoms such as having trouble seeing in dim lights or at night. If your eyes have trouble adapting to darkness, this could be a sign of deficiency. Most of the other symptoms are also related to eye conditions. These include dry eyes and nearly white spots on the eyelids. Other symptoms may show through the skin. Dry skin is often a sign of deficiency. Wounds that will not heal may also be a sign. Furthermore, dry and weak hair and nails may be symptoms of vitamin A deficiency.

It is recommended that adult males 19 years of age and older get at least 900 micrograms of vitamin A per day. Adult females this age and older are recommended to get a 700 microgram intake of the mineral per day. However, pregnant womens intake recommendations increase to 770 micrograms while females in lactation should get 1300 micrograms a day.

Consuming foods high in vitamin A is one of the most obvious ways to prevent deficiency. There are many vitamin A rich foods such as apricots, broccoli, carrots, fish, ghee, liver, mangos, milk, papayas, pumpkins, spinach and sweet potatoes. Liver and carrots are by far the best food source of this mineral. Cooked beef liver has more than 27,000 micrograms and cooked chicken liver has nearly 13,000 micrograms. There are more than 22,500 micrograms of the mineral in carrot juice while boiled carrots have more than 13,000 micrograms.
