Foods For Eyes Healthy - Eyes are the five senses are very important / essential. Conceivably, if we experience eye damage or blindness, we can not enjoy and feel how beautiful this universe. In fact we often forget to make eye care, although, as well as other parts of the body, the eyes may be affected by disorders or health problems. Disorder-disorder can be caused by air is not clean or polluted, solar radiation, radiation from too long in front of computers, and other disturbances.
Studies conducted by the Eye Disease Prevalence Research Group (2004) estimates that by 2020 the number of people with eye disease and blindness in the world will reach 55 million inhabitants. The study also mentions that the eye disease and blindness will increase, especially for those who have aged over 65 years. A person aged 80 years or over who is 8% of the total population, suffered blindness as much as 69%.
Health problems in a common eye problem is the decline in the function of vision, red eye symptoms without any decrease in visual function, and red eyes with decreased visual function. Until now, eye disease that affects many are cataracts, glaucoma, and infection.
Along with increased attention and knowledge of the influence of nutrition on health, especially the health of the eye causes the rapid market growth of eye health products. Most of the products for eye health supplements that are marketed now shaped. In addition to antioxidant compounds (vitamins A, C, and E) that has previously been known to improve eye health, other compounds such as lutein, zeaxanthin, and astaxanthin, recently known as a compound that can improve eye health.
Lutein, a yellow carotenoid family of compounds found in many green vegetables. Lutein in the macula and are believed to protect the eyes from oxidative damage by ultraviolet irradiation (UV).
Macula was in the midst of the retina and directly adjacent to the lens of the eye. Macula is a small area that contains millions of cells that help produce sharp eyesight to read or see objects clearly.
Other carotenoid compounds present in the macula is is zeaxanthin, which are known to provide benefits for eye health.
Research conducted by Chitchumroonchokchai and colleagues in 2004 from Ohio State University, showed that lutein and zeaxanthin may protect the human lens cells from UV exposure, which is a major cause of cataract disease. In addition, they compared the antioxidant activity of lutein and zeaxanthin as vitamin E. The results indicate that lutein and zeaxanthin showed 10 times higher activity than vitamin E in protecting the lens cells from damage caused by ultraviolet light.
In the same year was also conducted research by Neuringer and colleagues, showed the ability of lutein and zeaxanthin in improving eye health. While testing on animals, sponsored by DSM Nutritional Products Switzerland, showed that supplementation or the addition of lutein and zeaxanthin increase the activity of antioxidants in the blood.
Group of other carotenoid compounds that actually has the ability to protect the macula from UV exposure is astaxanthin. Guerin et al. (2003) mentions that the ability of antioxidants and anti-inflammatory compounds astaxanthin can give the effect of eye protection from UV rays.
Until now, the antioxidant activity of the compounds lutein, zeaxanthin, and astaxanthin mechanism to respond to an increase in eye health. Free radicals derived from UV light or air contamination, into the eye resulted in the oxidation reaction of molecules susceptible to the lens of the eye.
These molecules are proteins and fats that make up the lens of the eye. The effect of this oxidation causes damage to the protein or fat in the eye lens. Along with increasing age and increasing accumulation of free radical stress, proteins and fats that are damaged will be greater in number. That's what makes vision blurred and gradually became blind.
Lutein, zeaxanthin, and astaxanthin nab free radicals (radical scavenger activity) by binding with it before the radical-radical damage to the eye lens protein or fat. Or in other words lutein, zeaxanthin, and astaxanthin may be cited as the eye lens protector against free radical attack.
Carotenoids are found in yellow-orange vegetables like carrots, green vegetables like broccoli, and red fruits and yellow-orange, like tomatoes, strawberries, watermelon, and mango. So by eating vegetables and fruits on a regular basis to meet the needs of lutein, zeaxanthin, and astaxanthin per day. Besides other effects of consuming vegetables and fruits is to increase the intake of dietary fiber which is very good for health.
