Eat This: Bulk Up On B's

The same vitamins that keep your energy up also lower your body's levels of homocysteine, an amino acid that may be linked to hardening of the arteries. Help protect your heart by getting your daily allowance of B6 (1.5 milligrams), B12 (2.4 micrograms), and folate (400 micrograms) from your diet. Here are a few grade-A sources of B's.

B6: Sweet potatoes

B6 and B12: Cod and sirloin steak

B12: Clams and mozzarella cheese

B12 and Folate: Soy milk

Folate: Spinach, beets and papaya

Folate and B6: Bananas, lima beans and sunflower seeds

B6, B12 and Folate: Breakfast cereals
