Human hearts from medico-legal autopsies were obtained from 3 regions of India where the edible oils used are different. These 3 population groups consumed either mustard oil (Calcutta), coconut oil (Trivandrum) or peanut oil (Madras). Among the saturated fatty acids, lauric acid was found only in the myocardium of subjects from Trivandrum (3.5% of the total fatty acids [TFA]), heptadecanoic acid only in the samples from Madras (1.4% TFA) and arachidic acid only in those of Calcutta (1.9% TFA). Erucic acid was present only in the samples received from Calcutta and acted as a marker of mustard oil consumption. It had a mean concentration of 5.6% TFA. From the level of erucic acid present in the myocardial lipid, it is apparent that, at the level of intake of mustard oil prevalent in India, the risk of developing myocardial fibrosis is slight.
