15 Zinc Rich Foods

Zinc is a fundamental mineral for the body, but it is not produced by the human body and is easily found in foods of animal origin. Its functions are to ensure the proper functioning of the nervous system and strengthen your immune system, leaving the body stronger to resist infections caused by viruses, fungi or bacteria.

In addition, zinc plays important structural roles and is an essential component of various body proteins. Therefore, lack of zinc can lead to changes in taste sensitivity, hair loss, difficulty healing and even growth and developmental problems in children.

Some of the main sources of zinc are animal foods such as oysters, beef or liver. Fruits and vegetables, on the other hand, are low in zinc, so people on a vegetarian diet, for example, should especially eat soybeans and nuts such as almonds or peanuts to keep their zinc levels balanced.
