Antioxidants Definition - Antioxidants are chemical substances in food that protect the cells against damage caused by substances called free radicals. Some popular and powerful antioxidants are vitamin A, lycopene, vitamin C, vitamin E, zinc, selenium, and omega-3-fatty acids. Free radicals are formed when oxygen is liberated during certain biological processes. If these oxygen molecules or "free radicals" are not mopped up (by antioxidants) and removed from the body, they can lead to cell damage and poor health. Foods rich in antioxidants protect against degenerative diseases by helping to get rid of free radicals.
Vitamin Definition - A vitamin is an organic substance needed by the body for biological processes, but that is not made by the body. Vitamins A, the B vitamins, vitamin C, vitamin D, vitamin E, vitamin K, vitamin B12, biotin, and folacin (folic acid) are key vitamins. The best source for vitamins is food. But if you cannot get enough from food, a vitamin supplement may be necessary. The sun is a powerful source of vitamin D. Different vitamins play different, but vital, roles in the body.
Mineral Definition - A mineral is an inorganic substance found in foods and needed by the body for certain life processes. A lack of essential minerals could lead to ill health, and death. Some common minerals include calcium, copper, iron, sodium, potassium, zinc, iodine, chloride, magnesium, manganese, flouride, boron and selenium. The proper balance of minerals in the diet is essential, as too much of one may interfere with the absorption and/or utilization of another.

Diabetes Definition - diabetes is a medical term used to describe a condition in which the body fails to properly store and use sugar. As a result, too much sugar may build up in the blood and lead to serious health problems, including coma, blindness, heart disease, kidney disease and amputation of the feet. There are two main classifications for diabetes. Type 1 diabetes and type 2 diabetes. Type 1 diabetes is mostly seen in children and is a condition in which the body does not produce enough insulin. Type 2 usually occurs in adults and is sometimes referred to as adult onset diabetes. But it is seen more and more in children, and is associated with the growing incidence of obesity. In type 2 diabetes, the body produces a great deal of insulin, but the cells do not respond to the circulating insulin, making it difficult for the sugar to be transported into the cells where it is needed.
