Whether from the concession stand or popped in the microwave, this movie staple has got no place in a fit man's diet. Saturated with unhealthy fats, unearthly levels of sodium, and in some cases, laced with chemicals, popcorn does not fuel an athlete's body for a strenuous training session, nor does it encourage recovery after a long workout. Microwave popcorn bags are also lined with something called perfluorooctanoic acid (PFOA), a chemical which is also found in Teflon pots and pans—yikes. There is a flip side, however. If you air pop the corn or pop it on the stove with a small amount of coconut oil, it turns into somewhat of a superfood, boasting high levels of antioxidants and a hearty dose of satiating fiber.
