Protein

Proteins are a macronutrient that the cells in your body use for structure. Protein is very important for building tissues, such as muscle.

Copper

Benefits and Plant Food Sources

Copper is an essential trace mineral necessary for survival. It plays a role in making red blood cells and maintaining nerve cells and the immune system. It also helps the body form collagen and absorb iron, and plays a role in energy production.

Calcium

Your body needs calcium to build and maintain strong bones. Your heart, muscles and nerves also need calcium to function properly. Some studies suggest that calcium, along with vitamin D, may have benefits beyond bone health: perhaps protecting against cancer, diabetes and high blood pressure. Food is the best source of any nutrient, and some plant foods are rich in calcium.
