There's new evidence that certain kinds of fatty foods can be worse for you than once thought.A recent study has shown that oxidized fat- found mostly in meats, deep-fried and processed foods and baked goods made with eggs and butter - speeds atherosclerosis or clogging of the arteries.
The oxidized fat is formed when the cholesterol in foods is exposed to heat and air and it rapidly promotes the build up of plaque, which can lead to a heart attack. The research was performed on animals but if proved on humans, it may become a new factor in heart disease risk.
For now, researchers recommend reducing the amount of processed and fried foods in your diet and cooking with healthier fats such as olive oil and canola oil. Eating plenty of antioxidant rich fruits and vegetables also helps fight plaque build up.
