If we have a deficiency of vitamins and minerals we can get sick as people got years back with beri beri, scurvy and many others. Replenishjing what is missing will bring us back to normal again. That is not prescribing drugs to cure a disease but using common sense to replenish the body with a nutrient God put on foods to keep us healthy. It might happen that we could be eating unproperly and as a result we get sick. Am I making sense, FDA? We will bring understanding about what kind of deficiencies can make us sick and how to correct it either with food or food supplements which is not the same but helps.
