It always said that "you are what you eat" when talking about weight loss. But poor eating habits have impact on our eyesight too. Here are 5 healthy food recommendation to maintain a clear eyesight.
1. Carrot
As children, we always told to eat carrot to have a clearer eyesight. That was so true. Carrot is rich in Vitamin A and Beta-Carotene. Beta carotene is a substance that is converted to Vitamin A in the human body. This vitamin helps transfer fat to energy.
Vitamin A is not just an eye's food. It helps maintain the surface linings of the eyes and the respiratory, urinary, and intestinal tracts. When those linings break down, bacteria can enter the body and cause infection.
2. Garlic, onions, shallots and capers
Garlic and onions may cause bad breath. But despite of the odour, garlic, onions, shallots and capers are rich in sulfur. Sulfur produces glutathione, an antioxidant that helps the lens of the eye. Alpha lipoid acid and MSM included in it helps when the eyes are exposed to UV lights. Garlic may contribute to keeping the blood circulating and keep cells in the eyes resilient. It contributes to strengthening the immune system as well.This is necessary for the production of glutathione, an important antioxidant for the lens of the eye, and the whole body.
3. Cold Water Fish
Mackerel, cod, sardines and tuna are excellent source of DHA. DHA provides structural support to cell membranes, and is recommended for dry eyes and sight preservation.
4. Eggs
People avoid eggs for being high in cholesterol. Although eggs contain cholesterol, it is still safe to consume eggs daily without the yellow yolk. Compare to the white yolk, yellow yolk has high level of cholesterol. Eggs are rich in cysteine, sulfur, lecithin, amino acids and lutein. Sulfur-containing compounds protect the lens of the eye from cataract formation.
5. Green leafy vegetables
Green vegetables such as spinach and kale are rich in carotenoids, especially lutein. Lutein is a yellow or orange pigment found in green vegetables. Lutein is concentrated in the retinas of your eyes and is necessary for good vision. Lutein helps keep the eyes safe from oxidative stress and the high-energy photons of blue light.
These 5 simple superfoods are only recommendation to include in your daily meal. They are easy to find and healthy. Apart from the above, vitamin supplement can help to fulfill your eye diet requirement.
