The AMA, not worth a fiddle fer nothin' most of the time, admits that 82% of diseases are diet-related disorders. Since crops are carried away from fields, instead of recycled back to the soil, the minerals they take out of the soil get depleted. The food today has less mineral content than it did in, say 1963. You'd have to eat 8 oranges today, e.g., to get the nutrients of one eaten in 1963. See Robert Barefoot for calcium research.
Calcium deficiency is the cause of over 147 diseases, kidney stones, osteoporosis, the more famous ones, and is touted as a preventive and even curative of cancer (Nobel Prize winner Paul Warburg). Kidney stones are calcium drawn from the bones and rest of the body due to dietary deficiency of calcium.
Copper deficiency leaves tissues without elasticity, leading to aneurysm, aortic aneurysm being the heart attack so many suffer.
Deficiency in chromium and vanadium are diabetes related, but it is mainly caused by the overdose of sugars, white fiberless flour, white fiberless sugar, and a 60% increase in the last decade of the 20th century, after the advent of high fructose corn syrup in the 1980's. See Dr. Joel Wallach, the Mineral Doctor for lots of research on minerals.
Get more minerals into your diet and see if you feel better. Steaming vegetables retains 90% of the nutrients. Boiling them washes them away, and microwaving destroys 90% of nutrient value. No wonder people eat and are still hungry. And sick.
