There is no direct link to quantity of berries and glaucoma. We suggest certain foods that provide nutritional benefits for overall eye health. In general....
Although limited scientific data exists on food-related therapy for glaucoma, a few things that may help include:
- Foods high in Beta-carotene, which are highly pigmented (red, orange, yellow), fat-soluble compounds naturally present in many fruits, grains, oils, and vegetables (green plants, carrots, sweet potatoes, squash, spinach, apricots, and green peppers).
- Bilberry or bilberry extract
- Ginkgo (Ginkgo biloba) has been used in several clinical studies for the treatment of glaucoma. Ginkgo seems to improve retinal blood flow in the eye, decreasing damage to the retina.
- B vitamins (thiamine and riboflavin) have been associated with reduced risk of cataract (sunflower seeds, beans, lentils, oats, spinach, asparagus, almonds)
- Omega 3 fatty acids have been effective in decreasing intraocular pressure (IOP) in some glaucoma patients. (hemp seeds, chia seeds, walnuts, and cold water fatty fish like wild salmon)
Overall: Eating a healthy diet full of fruits and vegetables helps to ensure that enough vitamins and minerals are consumed for use by the body and eyes. Some nutrients that are especially important to eye health include vitamin A, vitamin C, vitamin E, and zinc. Drinking fluids in small amounts over the course of a day can help individuals with increased intraocular pressure (IOP). Drinking a quart or more of any liquid within a short time may increase eye pressure. Limiting caffeine to low or moderate levels may be helpful.
Be sure to discuss these w/ your Dr. to ensure there are no nutrient or food/drug interactions with any medications you may be taking.
