5. Keep Your Blood Pressure—And Your Weight—In Check
People with high blood pressure are more likely to develop AMD, according to the American Academy of Ophthalmology. The theory is that increased pressure damages blood vessels. This hinders blood flow to the eyes, making it harder for protective nutrients to reach the retina and for damaging free-radical debris to be carried away. Losing extra pounds if you’re overweight or obese might also help. Body fat is a major storage depot for fat-soluble nutrients, and excess fat tissue can act as a “sink” for some eye-protective nutrients, making them less available to the macula.
