The Blood Pressure Connection
Cutting back on sodium, especially if you already have diabetes, may be important, as well. Too much sodium is known to increase blood pressure. And high blood pressure damages blood vessels. In one study, Roy and her colleagues showed that dietary sodium, even in the absence of hypertension, increases the risk of complications from retinopathy. High-calorie diets also increased the danger.
The good news is that the same dietary rules that will protect your heart may also help you keep your vision. Those rules are simple:
- Build your diet around fruits and vegetables
- Help yourself to nuts, beans, and whole grains
- Favor fish and chicken and other lean meats
- Eat sweets sparingly
- Avoid highly processed foods as much as possible
- Go easy on salt
By following a healthier diet, researchers at the University of Liverpool recently estimated, the risk of macular degeneration could be cut by up to 20%.
