Reduce the likelihood of developing glaucoma by eating more greens throughout the day. A large and lengthy study recently concluded that a high-nitrate diet (aka a diet with green veggies) significantly decreased a person’s risk for glaucoma in old age. “…those who consumed the most nitrate – mostly from green vegetables like kale and spinach – were 21 percent less likely than those who ate the least nitrate to develop open-angle glaucoma by the time they were in their 60s and 70s.” This is the first study to observe a potential link between diet and glaucoma, which is very beneficial since glaucoma exhibits no symptoms.
