Levels of trans fats in diets consumed in developing economies

Cardiovascular complications are a leading cause of mortality worldwide, and dietary patterns and lifestyle are key factors responsible for their progression. Sedentary lifestyle and transient changes in nutrition have led to drastic increases in such maladies during the last few decades, and dietary changes are significant, as they are coupled with high fat intake, especially trans fats. In developed countries, legislations and monitoring systems have resulted in reduced consumption of these metabolites. The developing world, especially South Asia, is also facing the menace of trans fats; lack of governmental interest and ignorance among consumers are the main reasons. In these regions, the use of hydrogenated vegetable oil (ghee) and shortening in deep-fat frying of culinary items, such as samosa, paratha, bhatura, poori, and tikkies, results in increased consumption of trans fats. Research investigations and cohort studies showed a positive correlation between consumption of trans fats and cardiovascular disorders. In this article, trans fats intake and its level in different products available in developing countries, particularly in South Asia, were reviewed along with information regarding processes involved in the production and possible reduction of trans fats.
