Minerals like calcium, iron, and zinc are especially important for athletes.

Recommendations of calcium intake are based on levels than can promote calcium retention, maximize bone mineral density, and inhibit bone loss. Lower calcium intake subjects the athlete to increased risk of stress fracture. Food that provide good calcium stores are the following: dairy products, fish with bones, broccoli, and fortified cereals and juices.

Iron makes up hemoglobin, myoglobin and oxidative enzymes and affects oxygen transport and aerobic metabolism. To achieve optimal aereobic endurance, consuming adequate amounts is a must. Iron depletion, the first stage of iron deficiency is the most common type of iron deficiency among athletes. Lean red meats, dark poultry, fortified cereals, whole grains, and legumes are good iron sources.

Zinc, which is found in meat, poultry, seafood, and whole grains, is essential for protein synthesis, healing, and immune function. Zinc is also found in antioxidant enzymes and enzymes involved in energy metabolism.

Although minerals are needed to work hand-in-hand with vitamins to ensure good sports nutrition, we must remember that consuming any mineral excessively can interfere with digestion and the absorption of other minerals. This may lead to mineral imbalances. Also, all minerals can be toxic in large doses.
