Is It True? No.
Why? Well, eating fries every day isn't the healthiest thing to do, but it's not the culprit behind your oily skin. "Eating greasy food won't make you break out, unless maybe you rub the food on your face," says Dr. Prystowsky. "There are some foods that are connected to acne, though. Whey protein can potentially flare up acne. It's used in protein bars and protein powders. Also, very sugary foods may aggravate acne."
The Lesson: Oily skin is best fought using the right cleansers and moisturizers.
