believed he was on the verge of demonstrating this mechanism "conclusively" and that 18 more weeks of work would nail it down. But instead of providing the funds, the ISRF nixed the project, assessing its value as "nil." One diabetes expert testified that anything more than 70 pounds per person per year -- about half of what is sold in America today -- might spark epidemics. The industry followed a similar strategy when it came to diabetes. By 1973, links between sugar, diabetes, and heart disease were sufficiently troubling that Sen. George McGovern of South Dakota convened a hearing of his Select Committee on Nutrition and Human Needs to address the issue. An international panel of experts -- including Yudkin and Walter Mertz, head of the Human Nutrition Institute at the Department of Agriculture -- testified that variations in sugar consumption were the best explanation for the differences in diabetes rates between populations, and that research by the USDA and others supported the notion that eating too much sugar promotes dramatic population-wide increases in the disease. One panelist, South African diabetes specialist George Campbell, suggested that anything more than 70 pounds per person per year -- about half of what is sold in America today -- would spark epidemics. In the face of such hostile news from independent scientists, the ISRF hosted its own conference the following March, focusing exclusively on the work of researchers who were skeptical of a sugar/diabetes connection. "All those present agreed that a large amount
