The essence of his conclusion from many years of research was:”I know of nothing so potent in maintaining good health in laboratory animals as perfectly constituted food; I know of nothing so potent in producing ill-health as improperly constituted food. This, too, is the experience of stock breeders, is man an exception to a rule so universally applicable to the higher animals.”,
a related conclusion to that reached independently by Albrecht on plants “health is the birthright of plants“,
In humans terms, adequately nourished humans are highly resistant to the onset and effect of most non-communicable diseases: as a generality, paraphrasing Albrecht, health should be the birthright of humans.
As part of his research, in the hunt for a better understanding of the impact of nutrition on health, he looked a t regional Indian diets, their impact on population health, including as to stature, general health and prevalence of local disease. He fed those same regional diets to his laboratory rats, and found they showed similar trends in build and disease prevalence.
