Trans fats

Trans fats are a type of fat found in some foods. Artificial trans fat is made when hydrogen is added to a liquid vegetable oil to make it more solid.

Harm

Trans fats can increase your risk of heart disease. They increase your “bad” cholesterol (LDL) and decrease “good” cholesterol (HDL), fostering the buildup of fatty deposits that can clog your blood vessels and lead to heart attack.
