The Aging, Antioxidants, Green Tea and Eye Disorders / Health
An old Chinese proverb says: "Better to be deprived of food for three days of being deprived of green tea for one." While it is an exaggeration to describe the healing properties of green tea as "miraculous", there is no doubt that green tea may have profound benefits to maintain weight loss, in supporting the recovery of cardiovascular disease, and even for management conditions as diverse as allergies and endometriosis. Not many people realize, however, that green tea is also helpful in slowing the progression of eye disease age-related.
Eye disorders are a common complication of aging. Most eye problems experienced later in life occurring in the "Ecuador" eye. There is a simple reason that the eye problems occur here.
The cells in the center of the eye grow faster because they have to cover more tissue. These cells are highly susceptible to injury and antioxidant deficiencies by exposure to the ultraviolet spectrum of sunlight. At the age of sixty, and sometimes before, free radicals can accumulate so that the proteins in the lens of eye begins to coagulate. Over time, these proteins bind in a pattern that looks like a star. These stars can be joined to form a cataract interferes with vision.
Take any vitamin and antioxidant
The remedy for the free radical damage is not necessarily to take every vitamin antioxidant. One of the rarely seen on eye care of aging is that excessive consumption of vitamin D supplements actually causes cataracts grow faster. And although you can not take as much vitamin C that you damage your eyes, take antioxidant vitamin C without their co-factors not help slow eye injuries.
One of the co-factor of the vitamin C is vitamin E. Vitamin C and E together and together recharge recharge the antioxidant glutathione in the lens of the eye. If you just take vitamin E without taking vitamin C, to grant a protection against the development of the kind of falls that make it difficult to drive at night (cortical cataracts), but not against cataracts that cause myopia (nuclear cataracts ). Taking only these two vitamins together reduces the risk of cataracts none at all by 70 percent.
Changes in the diet, however, offer a further protection. A study of nutrition and cataract formation conducted in Europe found that people who eat more broccoli, cabbage, green peppers, spinach, melons and tomatoes were the least likely to have cataract surgery. The Health Professionals Follow-Up Study found similar results for American men who consumed the most servings of broccoli and spinach a week (about 1 of each is enough). The Nurses' Health Study found that women who consumed most of America lutein and zeaxanthin, yellow pigments found in foods such as sweet corn and egg yolk, enjoyed a further reduction of 22 percent in the risk of cataracts. Green tea, however, reduces the risk of cataracts further.
The benefits of green tea for Cataracts
The protective compound in green tea that prevents the progression of cataract known epigallocatechin gallate, also known as ECGC. This antioxidant prevents energy generating parts of the cell known as the mitochondria of "burnt and abandonment" eye when the lens is exposed to ultraviolet light, industrial chemicals, and other sources of damage by free radicals.
ECGC maintains free radical damage in the eye of the induction of a process known as apoptosis or "cell suicide." Interestingly, at least under laboratory conditions, this compound protects the eye green tea better at lower concentrations than at higher concentrations. A very small amount of compound delivered through the bloodstream to the eye is sufficient to prevent a series of steps initiated when the energy-making machinery of the cells of the eye are stressed. A huge dose of the compound, more than you can actually get to take green tea supplements and much more that you can get from drinking green tea has no effect at all.
Why is it a good idea to use green tea as part of a program to prevent eye disorders
If you live in cheeseburgers, Hostess Twinkies, and Starbucks coffee drinks, drinking green tea or taking green tea supplements will not really do much to prevent eye disorders. Green tea is good to stop a major source of destruction of ocular tissue, cell suicide in order after years of Exposure to sunlight has damaged the power outlet center cell. The EGCG in green tea, however, does not stop the cellular damage that comes from outside of the cells of the eye, such as may be caused by prolonged use of any of the following prescription:
Chemotherapy with Adriamycin (doxyrubicin)
Antidepressant drugs such as Elavil (amitriptyline) and Tofranil (imipramine)
Cholesterol-lowering drugs such as Lipitor (atorvastatin), LoCholest or Questran (sold under the generic name cholestyramine or colestipol), Mevacor (lovastatin), Pravachol (pravastatin), Zocor (simvastatin), etoclopramide (Mexalon or Reglan) gives by vomiting or nausea, or oral contraceptives at any dose
All these drugs increase the risk of damage to the lens of the eye that can lead to cataracts. Green tea does not guarantee that you will never develop cataracts, but the long-term clinical evidence and laboratory studies suggest that should help.
How green tea as part of the Prevention of Eye Disorders
In general, you can not drink enough green tea for ECGC levels you need to have an effect on long-term eye health. Some studies estimate that the benefits begin in about 40 cups a day, which is enough to interfere with other aspects of nutrition.
By far the easiest way to get the benefits of green tea to any aspect of your health is to simply take a supplement standardized to EGCG. As little as 300 mg a day may be beneficial, but about 3,000 mg per day is effective in the prevention and recovery support for many health conditions.
