Delaying Progression to Advanced AMD
Age-related macular degeneration (AMD) and its progression as an eye disease can be significantly impacted upon by the diet and nutrients a person ingests every day. The Age-Related Eye Disease Study (AREDS), found that a specific formulation of antioxidants and zinc showed up to 30% reduction in the rate of progression to advanced AMD and its associated vision loss. In 2014, the updated results of the AREDS2 study were released. This added crucial new ingredients to the original formulation and found even better outcomes for reducing progression. The formulations are not a cure and will not restore vision already lost to the disease. They have been shown to be effective in delaying progression to advanced AMD. It is always best to alter your own diet to ensure you are maximising the nutrients you need for healthy eyes.
The Best Foods to Eat Plenty of:
Green, Leafy Vegetables: Spinach, kale, broccoli, rocket, cabbage
Orange & Yellow Fruit and Vegetables: Capsicum, carrots, pumpkin, oranges, squash
Blue & Purple Fruit and Vegetables: Beetroot, blueberries, Goji berries, kiwi fruit
Red & Pink Fruit and Vegetables: Red grapes, cherries, raspberries, capsicum
All coloured fruit and vegetables Antioxidants that are essential in maintaining good macula health. For a comprehensive plan of the best foods to eat for eye health, including recommended quantities to ensure the optimum nutrient benefits based on the latest research, visit our Nutrition and the Eyes page (here). Omega-3 fats are the best for your eye health. This means fish, canola oil, olive oil and flaxseed oil. Eat fish four times a week. The best fish are tuna, salmon, sardines and mackerel.
Things to Avoid:
- Too much red meat, sugar, refined carbs, fried, trans and saturated fats, processed foods
- If you take Warfarin, you are not able to eat green, leafy vegetables and you may be diet deficient in antioxidants. You should then take 1 x MD Eyes tablet per day.
Lutein and zeaxanthin are found in the macular pigments. This is the protective layer of the retina essential to good macula health. A deficient macular pigment layer will make you more prone to developing AMD. They are carotenoids that protect against phototoxic blue light and UV radiation. Multiple research papers have shown that 10-20mg of lutein a day in needed to be protective in AMD, which is equivalent to two cups of raw spinach or leafy greens. High ORAC (antioxidant capacity) berries, especially bilberry, wild blueberry, Goji berry, grape seed extract and Resveratrol have been found to be potent inhibitors of angiogenesis (new blood vessel growth) by reducing VEGF expression as well as reducing oxidative damage to the macular pigment. Your health food store will recommend supplements with resveratrol and bilberry.
The above dietary changes can be supplemented by taking 1 x MD Eyes capsule per day to ensure your full nutrient needs are met. The crucial element to MD Eyes is the level of Lutein and Zeaxanthin, which is formulated to match the AREDS2 recommended levels. This is why Envision Optical recommends MD Eyes as the current best macular supplement available.
