Quoted from The Hundred-Year Lie:
Over the past one hundred years our cancer mortality rate has gone from 3 percent of all deaths to 20 percent of all deaths. Our incidence of diabetes went from 0.1 percent of the population to almost 20 percent. Heart disease went from being almost nonexistent to killing more than seven hundred thousand people a year. At the same time, health care costs have risen until the United States now spends twice as much on medicine and care per person per year than any other industrialized nation in the world.
In the first report, based on a study from the science journal Public Health, I learned that the incidence of death from brain diseases, such as Alzheimer’s, Parkinson’s, and motor neuron disorders, was found to have tripled in nine Western counties, including the United States, during the period of 1974 to 1997. The most likely causes researchers identified were exposure to pesticides sprayed on crops, synthetic chemicals from the processed foods that we consume, and industrial chemicals used in almost every aspect of our modern lives. “There’s no single cause,” admitted Colin Pritchard, one of the British authors of the study. “Most of the time we have no studies on all the multiple interactions of the chemical combinations.”
Food seemed to be a major culprit for this toxicity, because Japan, alone among the ten countries studied, experienced no increase in brain disease mortality, apparently as a result of the Japanese diet being healthier than Western diets. When Japanese citizens relocate to Western countries and consume processed foods, their disease rates exceed those of Japan as a whole.
