Eye Health Guide
All things related to health are related to nutrition. Any eye health guide has to emphasize this connection.
Vision
Your eyes may the window to your soul; they are also a reflection of your health. Many eye problems are a refection of your nutritional status. As people age they may experience vision loss due to cataracts, macular degeneration (AMD) and other sight problems.
Eye Health Study
Agricultural Research Service (ARS) – funded scientists at the Laboratory for Nutrition and Vision Research are finding that healthy eating can reduce health costs by protecting the vision and the quality of life. The laboratory study directed by Allen Taylor is part of the Jean Mayer USDA Human Nutritional Research Center on Aging at Tufts University in Boston. Mass.
One study indicated that regularly consuming a combination of protective nutrients and a low-glycemic-index, or “slow carb,” diet provided an AMD protective effect. A food’s glycemic index is an indicator of how fast the carbohydrate it contains will spike blood sugar levels. The macula is a 3-millimeter-wide yellow spot near the center of the retina responsible for the central field of vision.
For the study, the researchers analyzed dietary intake and other data from more than 4,000 men and women, aged 55 to 80, who had participated in the long-term Age-Related Eye Disease Study, or AREDS. Led by Chung-Jung Chiu, the researchers ranked intake of each of several nutrients consumed during the AREDS study, then calculated a compound score to gauge their combined dietary effect on the risk of AMD. The scoring system allowed them to evaluate associations between individual – and combined – dietary nutrients.
The nutrients that were found to be most protective in combination with the low-glycemic-index diet were vitamins C and E, zinc, lutein, zeaxanthin, and the omega-3 fatty acids known as DHA and EPA. The 2009 study was published in Ophthalmology
No Surprise
It’s no surprise that every cell, function, and organ is dependent on the nutrition that you supply them with. It is simply, disease can’t take root as easily in a healthy body. The way to good vision is by consuming a nutrient rich diet.
Most fruits and vegetables supply vitamin C in ample amounts. This list includes oranges, grapefruit, strawberries, papaya, green peppers, and tomatoes. Vitamin E is found in nuts, seeds, and wheat germ. Lutein and Zeaxanthin are found together in many foods. Dark green leafy vegetables are a good source. It is also found in smaller amounts in broccoli, orange peppers, corn, peas, persimmons, and tangerines.
These are delicious ways to both general health and vision health. Achieving the benefits of good eyesight supports vascular health within the eye and improves visual acuity. It has been found than carotenoids protect against free-radical induced DNA damage. The density of your macular pigments composed (composed of Lutein, Zeaxanthin, meso-zeaxanthin) is essential to proper vision.
These may be big words, but all one has to know is eating lots lutein and zeaxanthin containing vegetables can help maintain the structural integrity of the macula.
As We See It
Plant compounds halt the progression of both macular degeneration, and cataracts. These are a significant cause of decreased vision. To halt vision loss with nutritional interventions is a very attractive solution.
