Research in animals and people has shown that, on a uniformly poor diet, the offspring of each generation deteriorates more and more, and in rats this continues up to eight generations. We do not know what the final stage will be in human deterioration. I suspect that many of the people with psychiatric disorders today, the addicts, the high degree of violence, the tremendous number of depressions and tension states and the great number of physical degenerations such as diabetes, arthritis, etc, are the modern manifestations of this continuing degeneration.
