While everyone is responsible for their own behavior, crime may well have a biochemical basis. A study of 318 Ohio convicts found 252 of them were malnourished. Those who remained on a new, healthy diet after leaving jail had few problems with the law. Alexander Schauss' book Diet, Crime, and Delinquency, states that malnutrition is the prime cause of criminal behavior. The U.S. is 89th among nations in death rate.
Cancer is the number one cause of disease-related death of children.
Perhaps the most interesting part of America's chronic borderline malnutrition is increasingly mineral deficient food, which comes from mineral deficient soil. One reason Americans tend to be obese is that if the body doesn't get the nutrition it needs, it craves more food. If the only food available is empty calories, well, that's what is eaten. One could consider what role such cravings have in substance addiction, too. America has the good fortune to have access to many diverse ideas.
