11. Eggs
Vitamin B12: .6 mcg in one large hard-boiled egg (10% DV)
Other body benefits: Eggs are a great source of protein and vitamin D, which is important for helping your body absorb calcium and maintain strong bones.
Best ways to eat it: Hard-boiled, soft-boiled, poached, scrambled—you can’t go wrong. “I love an omelet with veggies and avocado paired with fresh fruit,” says Sass. “Or eggs in a salad with chopped veggies, pesto, and quinoa.” If you’re watching your cholesterol, keep an eye on portion sizes: one egg yolk contains about 60% of your daily allotment of dietary cholesterol.
12. Chicken
Vitamin B12: .3 mcg in 3 ounces of roasted chicken breast (5% DV)
Other body benefits: Chicken is a lean protein, making it a terrific fat-burning food (it has a high thermogenic effect, meaning your body can burn about 30% of the calories it contains just by digesting it).
Best ways to eat it: There are countless healthy ways to eat chicken, whether you prefer it grilled, roasted, or baked in the oven.
