In recent years, the number of people who have decided to bet on a vegetarian or vegan diet has been increasing. The vegetarian does not consume meat of animals and the vegan animal product of animal origin. The point is that, although vegetables are very important for our body, the truth is that those who carry this type of food, could suffer malnutrition. That is, they could not get enough food sulfur. In addition, eliminating from the vegetarian diet all foods of animal origin can lead to “serious deficiencies”, since there are nutrients that are not possible to obtain through plant foods.
