Quick. Name a few fast foods and desserts that are bad for you. Pizza, cheeseburgers, chocolate ice cream. Guess what? They’re actually good for you. Science to the rescue from Prevention:

Science really has rescued some of our naughtiest foods from the taboo list. New studies suggest that former no-no’s like red meat, ice cream, and cheese may add to better health and longer life. This isn’t an excuse to go out and binge on every burger you see—overdoing calories and saturated fat is an invitation to obesity, clogged arteries, cancer, and diabetes. But indulging in these once-forbidden treats once in a while (and in waistline-friendly 400-calorie portions) may actually boost the health of your diet.

Pizza, beef, cheese, ice cream, and chocolate. Today is a good day.
