I came across an online article about 5 essential nutrients to maintain your eye's healthy. I would like to share some of the key points here. The article stated that there are many different kinds of ways for your eye to stay healthy. Especially, the most important is "meal" and essential nutrients are A-vitamin-A, B-vitamins, Lutein-Zeaxanthin, omega-3 fatty acids and Anthocyanins. Each nutrient is as follows A-vitamin)It is necessary to help cells, which feel light, work normally. It also can make you see things easier even in dark place. Livers and eels contain them. Green and yellow vegetables are also rich in them as be-ta carotene. B-vitamins)They are composed of eight kinds of vitamins. They are abundant in pork, chickens, livers and fish. They can contribute to preventing eyesight from deteriorating and eye diseases. Lutein and Zeaxanthin)They help absorb blue light comes from sunlight and electronics' screen. They also improve eyesight and are especially expected to improve night vision and enhance contrast sensitivity. They are abundant in green and yellow vegetables such as spinach, kale and broccoli. Omega-3s)It helps retain moisture on the eye's surface and is essential to develop eyesight. It is expected to prevent eyesight from deteriorating and eye disease by suppressing eye's inflammation. It is abundant in fish oil which fatty fish contains, vegetable oil and walnuts. Anthocyanins)It protects retina and eye cells from oxidative damage and improves eye's blood circulation. It also helps eyesight in dark place. It is abundant in blueberry, cherry and cabbage. I just turned 60 this April. In the case of over 50, it is time to have a high risk of macular degeneration and cataract. That's why I might want to eat vegetables rich in Lutein and Zeaxanthin, and get plenty of fatty fish with omega-3s. I'm big on food and going to pick up dishes carefully when I have lunch at my company's cafeteria and so on.
