"Epidemiology of ischaemic heart disease in India with special reference to causation.", S L Malhotra, Br Heart J. 1967 Nov; 29(6): 895–905. Old study but very memorable. S.L. Malhotra analyzed statistics of 1.15M employees of India Railways from 88 Railway company owned hospitals for the employees and their families. He found that the Southern employees consumed 19 times less animal fat than the Northern India, smoked 1/10-th of the cigarettes, ate less sugar - and had 7 times higher rate of ischaemic heart disease!
