Even when they don't have trans fat, fried foods in restaurants are often cooked in oil that is reused. This can create by-products that have been linked to a variety of diseases. And fried foods are highly caloric. "The point is that [frying] causes a food to absorb more fat and calories," Bob says. "It's why I want you to replace it with some other alternatives."
One alternative you can try is oven-frying. Cut potatoes into strips, toss or spray with a little olive oil, salt, and pepper, and cook in a 400° oven until brown. And if you can't live without potato chips, choose baked varieties made without trans fat.
