    Vitamins and Minerals: Which Do What?

    Vitamins. Vitamins are essential to good health. Vitamin A helps to develop and maintain body tissues such as bone and skin; it also helps the body’s vision, nervous system functioning, reproduction, and growth. The B vitamins are responsible for increasing the production of fats, proteins, and carbohydrates as well as assisting with metabolism, building red blood cells, and maintaining the protective covering of the nervous system.

    Vitamin C helps form tissues, cells, bones and teeth; heals wounds; and improves the immune system’s performance. Vitamin E protects the outer cell membranes from harm, thus assisting the immune system in fighting off diseases. Vitamin K helps the body’s blood clot in wounded areas.
    Minerals. Minerals also have a broad range of functions. As many as 20 minerals play significant roles in the body. “Microminerals,” or minerals that the body only needs traces of, can fight off serious illness. These include copper, iodine, chromium, iron, fluorine, tin, zinc, nickel, vanadium, manganese, silicon, molybdenum, and selenium. “Macrominerals,” or minerals that the body needs large amounts of include magnesium, sodium, potassium, chlorine, phosphorus, calcium, and sulfur.

    Zinc is responsible for helping metabolize proteins and keeping enzymes functioning. Copper is needed by enzymes for metabolizing. Iodine assists the thyroid gland in working properly. Calcium and phosphorus build bones and teeth. Iron delivers oxygen to the body’s cells. Potassium helps muscle contraction, maintains the fluid balance of cells, helps transmit messages through the body’s nerves, and keeps the kidneys and heart working correctly.

    How they interrelate. Vitamins and minerals not only help the body function, but they work to strengthen each other. The body absorbs iron through the help of vitamin C. Vitamin D helps the body absorb phosphorus and calcium. Vitamins D and K are the only vitamins the body can supply for itself. The skin creates vitamin D when it is exposed to sunlight. Vitamin K is produced by intestinal bacteria. Outside sources must supply the body with all other vitamins.
    Vitamins that Wash Away, and Vitamins That Build Up

    Vitamins are divided into two categories by the substance that carries them throughout the body.

    Water-soluble vitamins are carried and stored all throughout the body by water. These vitamins need daily replacement because they are lost in body fluids such as sweat and urine. Water-soluble vitamins include folacin (folic acid), biotin, pantothenic acid, thiamin (B1), riboflavin (B2), niacin (B3), pyridoxine (B6), and cyanocobalamin (B12).

    Fat-soluble vitamins – These vitamins, such as A (retinol), D (calciferol), E (d-alpha-tocopherol), and K (menaquinone), are carried by fats located in the bloodstream. Since fat is stores better than water, it is less critical when the intake of these vitamins is interrupted than when water-soluble vitamin intake is interrupted. However, when extreme amounts of these vitamins are taken, toxic levels can become present in the body.
    Vitamin and Minerals as Supplements

    Some dieticians do not like the idea of taking pills to replace a healthy diet. Vitamins should not be used as substitutions for a healthy diet, but rather as supplementation. Experts do not recommend vitamins in pill form despite the beneficial effects; this is due to the fear that people will use them to replace healthy eating habits.
    What are vitamins?

    Vitamins are essential substances that cannot be manufactured by the body. We need small amounts of vitamins for growth and development. Without vitamins the body cannot survive.

    The term vitamin is derived from the phrase vital amine. There are two types.

    Fat-soluble vitamins (A, D, E and K) are usually found in meat and meat products, animal fat and vegetable oils, dairy products and fish. They are transported around the body in fat, and your body stores any excess in the liver and fatty tissues. This means you don't need to get them from food sources every day.

    Water-soluble vitamins (B, C, folic acid) are found in meat, fish, fruit, vegetables and wholegrains. They are transported around the body in water. This means your body can't store them because you pass the excess through urine. You need to eat foods containing these vitamins every day. Water-soluble vitamins can be destroyed by cooking, so steam and grill rather than boil.

    • calcium

    • iodine
