After finishing my doctorate in chemical pathology at the Royal Post-Graduate Medical School, London in 1960, I worked five years at Makerere Medical School in Uganda, and I became mainly interested in the pathogenesis of the problems of Ugandans. Possibly, their propensity to eating huge quantities of green bananas might have had something to do with their intestinal disorders which resulted in volvulus and double volvulus being the #1 reason for surgery: The green banana is rich in serotonin which stimulates intestinal motility. The other unique problem was endomyocardial fibrosis (EMF) a fibrotic condition which affects the endo- and myo-cardium, leading to heart failure and death. But the idea that diet was a factor in EMF did turn out to be right. Africa had taught me that nutrition was important. {}
