Atherosclerosis is a condition where hardening and narrowing of arteries take place that causes risk of heart attack. Dietary trans fat plays an important role in the development of this disease. Bad cholesterol (LDL) enters the arteries where it is digested by white blood cells. With the gradual increase in the amount of cholesterol and cells develop plaque in the artery that hinders the blood flow through the artery. Increase in the size of plaque causes more difficulty in blood flow.
Trans fat are unsaturated fat that increases the risk of coronary heart diseases such as atherosclerosis. Sheep. cattle, dairy products and partial hydrogenation of vegetable oil contain trans fat.
