One of the common diseases in the elderly cataract increasingly threatening the health of the elderly. The so-called cataract, the crystals in the eye becomes cloudy resulting not see objects in front of the disease.
In recent years, many research workers through a large number of laboratory studies, that the cataract may be the combined result of many factors, crystal oxidative damage is the formation of the initial factors. The study found that the crystal itself has the function of certain defenses to oxidative damage, such as crystal, some cleaning agents and other organic matter, can remove some of the special reaction intermediates, the crystals from damage; mainly vitamin C, vitamin E , beta-carotene, glutathione, vitamin B1, vitamin B2 and so on.
In addition, there are a variety of trace elements and minerals is also involved in the metabolism of the crystal protein, once the lack of these vitamins and related components, metabolic disorders, increased oxidation protein composition, the crystals gradually turbid cataract formation.
The experts believe that vitamins and trace elements have a very important role in the prevention of cataract formation and development Therefore, older people usually should intake rich in vitamin C, vitamin E, beta carotene, glutathione, vitamin B1, vitamin B2 and other vitamins of the food.
Therefore, to prevent cataracts, the elderly should also add some extra vitamin nutrition formulations, to supplement the daily required nutrients, disease prevention and treatment.
