The lack of a nutrient is highly overemphasized. The only documented cases of true malnutrition (scurvy, beriberi, or pellagra) occur when people are starving—when the food is limited so that even though the human is craving the right foods, the food is unavailable. Examples of this occurred when people spent years in non-motorized ships or during war times when trapped soldiers ran out of a variety of foods. Once they were rescued, the symptoms went away. Early civilization did not have these guidelines, and yet each generation for thousands of years has used God’s biological feedback system, which guides all animals and humans to eat what their body is calling for.
