What you eat affects your eyes — and for people with AMD or at risk of it, certain nutrients matter more than most. No food cures AMD, and no diet alone replaces the specific evidence base behind AREDS 2 supplementation for intermediate or advanced cases. But a nutrient-rich diet is a genuine and meaningful part of looking after your sight throughout life.

Leafy Green Vegetables

The richest dietary sources of lutein — the primary carotenoid in the macular pigment — are leafy greens. Kale, spinach, Swiss chard, and collard greens are all excellent choices. Cooked or raw, they contribute meaningfully to lutein intake.

One practical tip: lutein is fat-soluble, so it absorbs better when eaten with a little healthy fat. A handful of spinach wilted in olive oil, or a kale salad with avocado, gives you better uptake than raw greens with no fat at all.

Even with consistent daily intake of leafy greens, most people reach only 2-4mg of lutein per day. The AREDS 2 trial used 10mg daily. Diet alone rarely bridges that gap for people with AMD — but greens remain worth eating every day regardless.

Eggs

Egg yolks are one of the best dietary sources of both lutein and zeaxanthin, and — crucially — in a highly bioavailable form. The fat content of the yolk aids absorption. A large egg provides around 0.2mg of lutein and zeaxanthin combined: modest in absolute terms, but well-absorbed.

Eggs also provide zinc, which plays a role in retinal enzyme function and is part of the AREDS 2 formula at a high therapeutic dose. Don’t avoid eggs for eye-health reasons — they’re one of the most nutrient-dense foods you can eat.

Oily Fish

Salmon, mackerel, sardines, herring, and trout are rich in omega-3 fatty acids (DHA and EPA). The retina has an unusually high DHA content, and adequate omega-3 intake generally supports retinal function.

It’s worth noting that the AREDS 2 trial specifically tested omega-3 supplementation as an add-on component and found it didn’t significantly improve AMD outcomes beyond the core formula. So omega-3s are not part of the AREDS 2 formula. But oily fish remains part of a heart-healthy, anti-inflammatory diet — and what’s good for your cardiovascular system is generally good for the blood supply to your retina.

Orange and Yellow Vegetables

Carrots, sweet potato, and butternut squash contain beta-carotene — a precursor to vitamin A, which is needed for the photoreceptors involved in low-light vision. Corn and orange peppers are good sources of zeaxanthin specifically.

One important note: the lung cancer risk associated with beta-carotene applies to high-dose supplements, not to beta-carotene from whole food. Eating carrots and sweet potato is entirely safe for smokers and everyone else.

Citrus Fruits and Bell Peppers

Oranges, kiwi, strawberries, and grapefruit are good sources of vitamin C, a key antioxidant that protects the lens and retina from oxidative stress caused by light exposure. Red and yellow bell peppers actually contain more vitamin C per 100g than oranges.

The AREDS 2 formula includes 500mg vitamin C per daily dose — significantly more than you’d get from diet alone, even with good intake. But dietary vitamin C remains worthwhile as part of a balanced, antioxidant-rich diet.

Nuts and Seeds

Almonds, sunflower seeds, hazelnuts, and wheat germ are good sources of vitamin E, another antioxidant in the AREDS 2 formula. Vitamin E helps protect cell membranes in the retina from oxidative damage. Almonds in particular are a convenient daily source.

Zinc-Rich Foods

Zinc is needed for retinal enzyme function, for transporting vitamin A from the liver to the retina, and for maintaining photoreceptor health. Good sources include red meat, shellfish (especially oysters), pulses, and pumpkin seeds.

The AREDS 2 formula includes 80mg zinc — a high therapeutic dose that’s very difficult to achieve through diet alone. If you’re taking AREDS 2 supplements, avoid other zinc-containing supplements to prevent excessive intake.

Diet vs. Supplementation for AMD

A diet consistently rich in the foods above is genuinely good for long-term eye health. For people without AMD, it may help reduce risk. For people with intermediate or advanced AMD, however, the AREDS 2 clinical trial provides the strongest available evidence — and it showed that reaching the specific therapeutic doses studied requires supplementation, not diet alone.

If you have AMD and are considering supplementation, discuss the AREDS 2 formula with your optician or GP first. They can advise whether it’s appropriate for your stage and check for any interactions with other supplements you may already take.
