The Link Between Nutrition and Retina Health: What You Need to Know
Originally published by Retina Group of Florida
For our eyes, a healthy diet offering ample amounts of essential nutrients may help maintain and improve vision, particularly for the retina. Adopting a vision-conscious diet may also improve outcomes for retinal disorders such as age-related macular degeneration (AMD) and diabetic retinopathy.

Setting the Table: What to Eat for Retinal Health
Incorporating foods rich in eye-friendly nutrients, such as antioxidants, is always a wise choice, as these compounds play a crucial role in shielding the retina and other eye structures from damage caused by oxidation and inflammation. Notably, the Mediterranean diet is particularly rich in antioxidants and other crucial nutrients, many of which can help patients with conditions like AMD or diabetic retinopathy. Popular food options that support eye health include:
- Large amounts of colorful fruits and vegetables, especially green, leafy ones
- Tree nuts (e.g., almonds, walnuts, cashews, etc.)
- Legumes
- Whole grains
- Seafood
- Reduced red meat
- Moderate amounts of dairy and eggs
- Healthy fats, like olive oil
- Herbs and spices, rather than salt
A low-glycemic meal plan may also support diabetic retinopathy by helping to minimize blood sugar spikes while also imparting benefits for cholesterol, blood pressure, and retinal vascular health. Food choices include fiber-rich carbohydrates, like green vegetables, whole grains, fish, and monounsaturated and polyunsaturated fats, rather than saturated or trans fats.
Essential Nutrients for Retinal Health
Consuming certain nutrients, many of which are antioxidants, may impart retinal benefits.
- Vitamin A is crucial for retinal health and plays a key role in enabling sight, including low-light and color vision, by producing pigments that allow cones and rods to function properly. Food sources rich in vitamin A include orange-colored fruits and vegetables such as carrots, fish, eggs, and dairy products. Additionally, vitamin A is naturally produced when carotenoids (plant-based pigments like beta-carotene) convert into vitamin A.
- Vitamin C is believed to potentially slow or prevent the progression of AMD, lower blood pressure, and improve narrowed arteries, which can support conditions like diabetic retinopathy. Good food sources of vitamin C include citrus fruits such as oranges and grapefruits, tomatoes, and strawberries.
- Vitamin D may contribute to the health of the eyes, potentially fighting tissue degeneration, relieving inflammation, and maintaining vision. Dietary sources of vitamin D include animal-based foods such as fatty fish, egg yolks, and cheese.
- Zinc is known to promote retinal function and assist in the production of melanin, a protective eye pigment. Some studies suggest that zinc may support diabetes management and reduce the development of advanced AMD. It's worth noting that while zinc is important, excessive intake can lower levels of another antioxidative mineral, copper, which is necessary for forming red blood cells. This potential imbalance can be countered by including copper-rich foods like legumes in the diet. Dietary sources of zinc include seafood and fortified cereals.
