Abstract
In the preceding paper on the relation of climate to the death rate from diabetes,1a definite climatic distribution of the disease was pointed out. In the United States, for instance, the death rate from diabetes was over twice as high in the northern as in the southern states, and this difference was even more marked in the colored than in the white population. Europe showed a similar increase in the death rate from diabetes toward the north, as did the provinces of Australia and New Zealand in the opposite direction. This definite tendency in the distribution of the disease raises the question of whether climate is the responsible factor, or whether a higher rate of consumption of sugar in the northern states and countries might not cause the increase. It has often been suggested that overindulgence in sugar may bring on diabetes, a suggestion that seems to be borne
