1. Pasta

Pasta’s biggest problem? (Other than the fact that it’s a refined grain that’s low on vitamins, minerals, and fiber.) “Portion size,” says Miller. “A 1/3 cup of pasta equals one serving size. That’s a lot less than many of us are eating.” But make it a side dish rather than your main entree — and choose a whole-grain variety — and pasta gets a pass.
2. Fast Food
Fast food fare is loaded with calories, sugar, salt, and fat. So why did it rank relatively okayish on this list? Because “many fast food restaurants are beginning to offer healthier options,” notes Miller. Choose lean, grilled protein — like chicken — rather than fried food. (More about that later.) And decline the condiments. “They’re often a source of added sugar, calories, and fat,” says Miller.
