Antioxidants such as beta-carotene have been associated with improved cardiac health. New research has found that the antioxidant lutein is potentially more beneficial than beta-carotene in preventing thickening of blood vessel walls. An 18-month study at the University of Southern California found that participants with the lowest blood lutein had carotid arteries four times thicker than those with the highest levels. The working theory is that lutein prevents LDL cholesterol from sticking to artery walls.

While its effects are still being investigated, early indications are that lutein may also protect eyesight, reduce cancer risk and combat arthritis. Good sources include kale, collard greens, spinach, broccoli, Brussels sprouts and corn.
