I doubt that it is possible to be totally healthy in the twentieth
century. Doctors Alsleben and Shute in their book How to Survive the
New Health Catastrophes state that in-depth laboratory testing of
the population at large demonstrated four universally present
pathological conditions: heavy metal poisoning, arteriosclerosis,
sub-clinical infections, and vitamin/mineral deficiencies. Those of
us who consider ourselves healthy, including young people, are not
really healthy, and at the very least would benefit from nutritional
supplementation. In fact the odds against most people receiving
adequate vitamin and mineral nutrition without supplements are very
poor as demonstrated by the following chart.
