Zinc is an essential mineral that plays many important roles in keeping your body functioning at its best. Some of the major functions involving zinc include: protein synthesis, wound healing, and immune function (which is why it is present in many cold remedy lozenges). It also plays a role in keeping your sense of taste and smell working properly. It is recommended that we consume zinc daily as we do not store a great amount of in our body. For males it is recommended that 14mg is consumed per day while only 8mg per day is required for females. Without adequate daily intake you are likely to suffer from symptoms such as skin rash, diarrhea, a decreased appetite and sense of taste, hair loss, and poor growth and development. In order to boost your daily intake of zinc, eat foods like seafood, meat, greens and whole grains.
