CAROTENOIDS AND VITAMIN E EFFECT ON THE EYES
Your eyes are complex organs that need many different vitamins and nutrients to function properly. Common conditions, such as diabetic retinopathy, age-related macular degeneration, glaucoma and cataracts, can impact your eyes. Though a variety of different factors causes these conditions, nutrition seems to have an influence on all of them — at least in part.
Many eye conditions are believed to be associated with oxidative stress, which is an imbalance between antioxidants and free radicals in your body.
CAROTENOIDS and Vitamin E are known to be efficient antioxidants and capable of scavenging reactive oxygen species generated during photooxidative stress.
According to nutrition research, an important key to healthy eyes and good vision may be getting enough CAROTENOIDS in your diet. In particular, carotenoids may help protect your eyes from the damaging effects of blue light and reduce your risk of macular degeneration later in life.
Carotenoids are pigments that give fruits and vegetables their vibrant red, orange, yellow and green colors. They act as antioxidants and have significant cancer-fighting properties.
Carotenoids such as lutein, zeaxanthin, and meso-zeaxanthin are mainly found in the macula (the form the macula pigments) in the center of the retina and absorb up to 90% of blue light. The absorption of this light can reduce the oxidative damage that occurs to this essential part of the eye.
The most sensitive part of the retina in the eye is called the macula. The macula has the highest concentration of photoreceptors in the retina and is the portion of the retina where our sharpest vision is produced. It also is responsible for our ability to perceive colors.
Carotenoids have many health benefits that extend past our eye health. They act as antioxidants in the human body. Certain types of carotenoids have cancer fighting and anti-inflammatory properties, which can also help fight heart disease. More importantly (for us anyway), certain carotenoids can be converted into vitamin A, an essential nutrient for our eyes.
Carotenoids are antioxidants important for eye health. For example, lutein is the yellow pigment in the macula that protects against certain eye diseases. Zeaxanthin helps macular degeneration.
VITAMIN E is a potent antioxidant that helps protect your cells — including your eye cells — from damage by free radicals, which are harmful, unstable molecules.
Vitamin E is believed to protect eye cells from unstable molecules called free radicals, which break down healthy eye tissue. This is what may lead to the formation of cataracts or age-related macular degeneration (AMD).
Antioxidants help fight free radicals, which damage tissues throughout the body. Sometimes, free radicals may damage proteins within the eye. This damage can result in the development of cloudy areas called cataracts on the lens of the eye.
Foods that contains carotenoids includes; Sweet patotoes, Carrots, Bell pepper, Kale, Spinach, Swiss chard, Mustard greens,Turnip greens, Collards, Green peas, Summer squash,Eggs.
Foods that contains Vitamin E includes; Peanuts, hazelnuts, almonds, sunflower seeds, sweet potatoes, cereals, Mustard greens, Swiss chard, spinach, kale, collard greens, Kiwi, papaya, Red bell peppers, broccoli, olive oil etc.
Eating foods containing these antioxidants is very essential for healthy eye sight, however, we all have experienced how hard it can be to eat healthy, these may be due to our busy schedules, or because we cannot get all the required foods in our stores or market or because we can lose their nutrients, either due to preservation method or the way we prepare them.
We your EYE DOCTORS, have a suggestion for you, OUR UNIQUE PRODUCTS, which contains all natural carotenoid and Vitamin E and in nutritionally significant quantities, can help you get high enough levels of each antioxidants for good eye health.
