Trans fatty acid, also known as trans fat, is an artery-clogging fat formed when hydrogen is added to vegetable oil, a process called hydrogenation. Many manufacturers use this process of hydrogenation because it reduces cost and increases the shelf life and flavor stability of their food.
Hundreds of household food items such as commercially prepared baked goods and margarine, and commercially prepared fried foods like onion rings, contain significant amounts of trans fatty acids. Astoundingly, typical French fries contain about 40% trans fatty acids, many popular cookies and crackers have from 30 to 50%, and doughnuts include some 35 to 40% trans fat.
Dangers of Trans Fat
Trans fat poses various serious health risks. It raises your body’s level of bad cholesterol (LDL) while scrubbing away the good cholesterol (HDL) that keeps your arteries clean. Your arteries can become clogged, making them inflexible, which can lead to strokes and heart attacks.
