In function of this, food education, drug supplementation or fortification/enrichment foods have been recommended to balance and ensure healthy life. However, certain nutrients, mainly microelements, are not always available to the population and in all foods. The ideal food should contain all the macro and micro nutrients that the human being needs. Additionally, it is important to point out that the necessity to know the elemental species capable of being absorbed and used by plants and mushrooms in their metabolism, as well as species formed after enrichment, since that is necessary to evaluate if these fortified foods have the same chemical characteristics of those formed when the food is grown under natural soil conditions and free of toxic metals.
In both studies it is necessary to evaluate the interactions between the different elements during absorption and translocation.
However, the enrichment through appropriate cultivation should be seen beyond the need to minimize nutritional deficiencies, since that it can also be applied in the resolution of environmental problems, aiming at reducing toxicity by heavy metals in food. For this, the fortified fertilizing of the soils is a promising strategy.
