A section of the people suffer micronutrients and trace element deficiencies (hidden hunger)...In order to enrich human diets could bio-fortification be a viable alternative to supplementation, genetically modified and transgenic foods?
It has shown to be a cost/effective way of increasing micronutrient intake. However, there are some questions on how to make this food available and affordable to the population that needs it.
Here is an interesting paper that could help you answer your question
Article Biofortified crops to alleviate micronutrient malnutrition
Since it is the process of breeding crops with higher level of micro and macro nutrients, and hidden hunger also malnutrition with insufficient micro nutrients, I believed it can overcome the problems in advance from fortification.
