Are you eating the foods that are best for your eyes?
Eating your way to good eyesight does not limit to carrots. Beta-carotene in these orange hue helps to promote eye health and protect vision. Beta-carotene is a precursor of vitamin A derived from plant sources. Our body can also convert beta-carotene from plant-derived foods into Vitamin A (Retinol) when needed. However the absorption and conversion rate depends on many factors. As a fat-soluble vitamin, adequate fat is vital to increase the chances of conversion. Pure vitamin A is primarily stored in liver and fatty tissues.
Preformed vitamin A is the vitamin A that can be found in animal products and is absorbed as retinol. This is the most usable and active form of vitamin A. Enjoy your eggs, milk, cheese and tuna as these are a few examples of food rich in the real vitamin A. The Recommended Dietary Allowance (RDA) for men and women is 900 and 700 µg retinol activity equivalents (RAE) daily.¹ Kick off your day with a glass of milk, have an oven-baked sweet potato fries as afternoon snack and include lots of leafy greens in your meal will load you with all the vitamins A you need.
High in antioxidants and lutein, Marigold flower of tagetes variety plays an important role in maintaining eye’s health. Marigold rich in antioxidant carotenoids that give the petals bright yellow and orange colors. The main carotenoids in marigolds are lutein and zeaxanthin which can be found in the macula of the eye. Also known as the “eye vitamin”, lutein may help filter harmful bluelight which may damage our vision. The third carotenoid found in the macula, which we called meso-zeaxanthin appears to be created in the retina from ingested lutein. Meso-zeaxanthin is not found in natural food sources. The best natural food sources of lutein and zeaxanthin are green leafy greens and egg yolks.
Another fruit that consumers will flock to for eye health is bilberry extract. As a shrub, Bilberry is one of the 3,500 species in Ericaceae family that in particular, is native to European countries. So, what is bilberry? This shrub is always confused with blueberry due to their similar appearance and is indeed closely related. In general, berries are a good source of micronutrients, fiber and anthocyanins. Most notably, the bilberry, also known as Vaccinium myrtillus L., is one of the richest natural sources of anthocyanins. As an antioxidant powerhouse, Anthocyanins are one of the polyphenolic components in the bilberry that give its bluish black colour and super-high antioxidant content.
Bilberry may help to improve eye health, especially night vision by increasing the production of a pigment called rhodopsin.² Rhodopsin is a compound that may improves visual adaption to darkness and blocks the activation of STAT3 enzymes that decrease rhodopsin levels.³ Anthocyanins in the bilberry may boost the production of rhodopsin. In fact, bilberry supplies over 15 different types of anthocyanins. This water-soluble pigment may appear red, purple or blue depends on PH level. It is a color pigment that gives eggplant, purple cabbage or cranberry its distinctive colors. Bilberry extract is usually standardized to contain 25 or 36 percent of anthocyanosides. This active component in bilberry is the key to vision health.
