Foods from different food groups provide all essential nutrients required for health. Fiber, an indigestible form of carbohydrate found in whole grain foods, fruits. A nutrient is a substance needed by organisms to stay alive and healthy. Carbohydrate, To provide energy, Cereals, bread, pasta, rice and potatoes.

Athletes frequently use protein supplements in their diet and will consume protein immediately after training, sometimes as a 'shake'.
Animal products — meat, fish, dairy; plants — lentils, nuts, seeds; protein supplements and shakes.
Carbohydrates Source of energy. Athletes need to consume larger quantities of carbohydrate to fuel their training and performance. Before your body can use protein to build and repair tissues, the large molecules of protein must be digested by enzymes into small molecules called amino acids.
Digestion of protein begins in your stomach with the aid of gastric juices. Through the action of a group of potent enzymes from the intestinal lining and the pancreas, digestion continues in the small intestine. From there, amino acids are absorbed into the bloodstream and transported throughout your body. Vitamin Absorption Vitamins are an important part of food and are absorbed through the small intestine. Vitamins are grouped based on how your body absorbs them.
Water-soluble B-complex and C vitamins dissolve in water prior to absorption. Fat-soluble vitamins -- A, D, E and K -- dissolve in fat to be absorbed and stored for later use. Water-soluble vitamins are not easily stored and surplus amounts are excreted in your urine.

Another important function of water is the transport of nutrients to the different cells and excretion of waste from the body. While the need for water varies with age, adults need about eight cups of water every day. Vitamins Of the 13 vitamins essential for health, nine are water-soluble and four are fat-soluble.
Water-soluble B vitamins thiamin, riboflavin, niacin, folate, vitamin B-6, biotin, pantothenic acid and vitamin B help release energy from food, prevent neural tube birth defects, are needed for DNA and RNA synthesis and play a role in development of the nervous system.
Vitamin C acts as an antioxidant and helps build strong gums, teeth and bones. Fat-soluble vitamin A is necessary for vision, vitamin D helps build strong bones, vitamin E functions as an antioxidant and vitamin K aids clotting of blood. Minerals Minerals required in amounts over milligrams daily, such as calcium, phosphorus, magnesium, sulfur, sodium, chloride and potassium are called major minerals, while iron, zinc, copper, manganese, iodine, selenium, molybdenum, chromium and cobalt are trace minerals because their daily requirement is less than 15 milligrams.
