Proteins are one the important source of nutrients required by our body. They are the building block of our whole body. While doing strenuous exercise or every time you work out you are tearing down the muscles and then rebuilding them. Proteins are necessary to repair and rebuild your muscles. Protein supplements are good for health like whey protein, soy protein. However, there are several natural sources of protein which are very good for health like egg whites, soyabean,milk and milk products, pulses and legumes, fish, chicken and other poultry products. Excess use of supplements are not recommended as it might lead to high uric acid formation in your body, as uric acids are by products of proteins.
