Next time your energy drops, skip the caffeine.
You’re better off grabbing fruit, nuts, or beans, says Steven Pratt, M.D., coauthor of SuperFoodsRx Diet (Rodale, 2008). These foods boost energy more effectively because they contain vitamins, minerals, and other nutrients that combat inflammation, support your immune system, and help you recover faster from exercise, explains Pratt.
Citrus
Snack on citrus fruits: They’re rich in vitamin C, a powerful nutrient that can have an antioxidant effect 20 minutes after you eat it, explains Pratt. If you prefer juice, choose one with pulp for more fiber, he says.
