54. You buy eggs fortified with Omega-3s but only eat the whites

THE RESULT: You miss out on the omega-3s.

THE FIX: Omega-3-fortified eggs come from chickens that have been fed a diet supplemented with omega-3 fatty acids (often from flaxseed), but if you eat only the whites to save on fat and calories, you’re missing out on those healthy fats and a host of other nutrients. True, the yolk contains 1.6g of saturated fat, but it also has 2g of monounsaturated fat and 0.7g of polyunsaturated fat, plus folate, calcium, beta carotene, and iron.
