Nutrition for Healthy Eyes
Good nutrition is very important for general health and eye health. Good nutrition helps the body to grow, prevent infection and to function properly.
Various studies and clinical trials of antioxidant vitamins found that certain foods can be associated with eye health. This food helps maintain healthy cells and tissues inside the eye. The main focus of antioxidants are vitamins A, C and E. These vitamins can be found in fruits and vegetables, including:
- Orange
- Kiwi
- Grapefruit
- Tomato
- Paprika
- Carrots
- Green leafy vegetables
- Legumes
- Beans
- Brussels sprouts
Two types of antioxidants known as carotenoids are lutein and zeaxanthin. Both antioxidants are also known to help eye health. Some studies found that people who diet rich in carotenoids, especially lutein and zeaxanthin had a lower risk of developing AMD.
Lutein and zeaxanthin are found naturally in vegetables and fruits. Lutein is found in yellow peppers, mango, bilberries and green leafy vegetables like spinach, chard and broccoli. Zeaxanthi can be found in orange, peppers, broccoli, corn, lettuce, spinach, orange, tangerine and eggs.
A large study in the Age Related Eye Disease Study (AREDS) showed that antioxidants, vitamins A, C, E, beta carotene and minerals as zinc oxide and copper as cuprix oxide, can help slow the progression of AMD. But very difficult to get the intake of vitamins from food in significant amounts, so people who have AMD are encouraged to get extra vitamins and antioxidant supplements.
After the AREDS research, then performed again on a study of how vitamins and minerals, whether from food or supplements, may help eye health in general, especially on AMD and cataracts. This study looked specifically lutein and zeaxanthin are associated with eye health.
From this study later found some kind of good food supplements for eye health, for example Biovision.
Research shows that many people do not get adequate vitamins and minerals from their diet, so they could consider taking supplements, especially for people who:
- Not eating enough fruit and vegetables.
- Diet does not contain many vitamins and minerals.
- Vitamins and minerals in food are not strongly absorbed in the body.
- It’s hard to get vegetables or fruit.
- Recommended by doctors.
