The unique change in the graph comparing 1946 with 1948 is exceptional, in that the change occurred immediately after the release of the diet instructions, and because such a change had never before occurred in the history of polio in this country. Although the 1949 polio epidemic for the country as a whole was more severe than the 1948 epidemic, the city of Asheville and the state of North Carolina experienced the greatest reduction in the number of cases in 1949 in spite of the fact that North Carolina had the second highest case rate in the country in 1948. The state of North Carolina had a case rate of 66.3 in 1948 and a case rate of only 6.3 in 1949. South Dakota had a case rate 153.9 in 1948, the highest in the nation, but showed a reduction in 1949 to only 63.0. Polio epidemics have occurred throughout the world in past years only in those countries with high per capita sugar consumption.
Epidemics are unknown in countries with low sugar consumption.
The greater the sugar consumption the more severe the epidemic. Foods must be in the condition in which they are found in nature, or at least in a condition as close as possible to that found in nature.
