The earth's general population is undergoing high levels of vitamin deficiencies and mineral deficiencies with values far less than established levels.

The reason that this is not widely publicly known, is that while we may get enough nutrients to overt outward symptoms such as bleeding gums from scurvy, the effect is slowing degrading our lives and life expectancy. As we consume nutritional poor foods, our body is still craving the required vitamins and minerals, which in turn stimulates you to consume more food and drugs.
