Trans fats raise gallstone risk?
Trans fats raise gallstone risk?: "Trans fats raise gallstone risk?
20/05/2005 - Trans fatty acids could ‘modestly’ increase the risk of gallstone disease, say US researchers, providing yet more evidence to encourage food makers to remove these fats from food formulations.
Although trace amounts of trans fats are found naturally, in dairy and meats, the vast majority are formed during the manufacture of processed foods.
They are created during the process of partial hydrogenation, when liquid vegetable oils are converted into margarine and shortening: essentially to extend shelf life and flavour stability, as well as contributing to a harder texture.
But mounting evidence suggests the TFAs raise LDL (bad) cholesterol levels, causing the arteries to become more rigid and clogged. An increase in LDL cholesterol levels can lead to heart disease, the number one global killer.
The latest study by Chung-Jyi Tsai and colleagues from the University of Kentucky, US examined the consumption of trans fatty acids in relation to the risk of gallstone disease in a cohort of 45 912 men.
The researchers hypothesised that trans fatty acids may cause a change in lipid profile, associated with gallstone formation.
TFA consumption was tracked using a food frequency questionnaire and newly diagnosed gallstone disease, by radiology or cholecystectomy, was ascertained every two years.
