Tea or soda caffeinated

Does consuming tea help prevent disorder?

Inexperienced tea is loaded with polyphenols, a phytochemical with 100 instances the antioxidant energy of diet C. Dr. Stephen Hsu, a clinical University of Georgia researcher, located inexperienced tea polyphenols assist remove loose radicals, that could damage DNA and lead to cancer. He further proved that green tea prompted p57, a protein that helps modify cellular growth.

Black tea may also help protect in opposition to numerous forms of most cancers, cardiovascular sickness, Alzheimer's, Parkinson's disorder, and rheumatoid arthritis, in step with Dr. Jack Bukowski and other researchers at the Brigham and women's sanatorium in Boston. They determined that drinking 20 ounces. of tea, every day for 2 weeks doubled or tripled the immune machine's output of a contamination fighting substance known as interferon gamma. Warm tea may also help beat back eye disease, examiner says

The take a look at of U.S. adults located that people who drank warm tea on a day by day foundation had been 74 percent less in all likelihood to have glaucoma, compared to folks that had been now not tea enthusiasts. The have a look at of U.S. adults discovered that those who drank warm tea on a day by day basis had been 74 percentage less probably to have glaucoma, as compared to folks who have been now not tea lovers.

Professionals have been short to stress that it may no longer be tea, itself, that wards off the eye disease. There might be something else about tea lovers that lowers their chance, said senior researcher Dr. Anne Coleman. But the findings do improve a question that needs to be studied similarly, in line with Coleman, a professor of ophthalmology at the University of California, l. a.

"Curiously," she said, "it was handiest hot, caffeinated tea that turned into associated with a lower glaucoma threat."

Decaf tea and iced tea confirmed no dating to the disorder. Neither did espresso, caffeinated or now not. It's tough to say why, in keeping with Coleman. "Is there something about the way of life of those who drink hot tea?" she stated. "Do they exercising extra, as an instance? We do not know." Glaucoma refers to a set of sicknesses in which fluid builds up in the eye, creating stress that damages the optic nerve. it is a leading motive of blindness in older adults, in step with the yank Academy of Ophthalmology, or AAO.

A few people face a better chance than others, the AAO says: They include blacks, humans with a circle of relatives history of glaucoma, and those with high blood stress, diabetes or other situations that affect blood move.

Some studies have cautioned that people who drink a whole lot of coffee have a heightened glaucoma chance. Others have hinted that caffeine can quickly boost strain within the attention. However, a few research have did not find an espresso-glaucoma hyperlink, Coleman said.

Her crew determined to look whether or not there is any connection between glaucoma and not handiest coffee, however tea or soda -- caffeinated or now not. So the researchers became information from a nationally representative government have a look at wherein U.S. adults underwent eye tests and filled out vitamins surveys.

Of almost 1, seven hundred survey members, 5 percent had glaucoma. Ordinary, Coleman's team found, the odds of getting glaucoma were 74 percent lower among individuals who stated they drank warm tea greater than six times every week, versus non-drinkers.

That was with a number of different factors taken into consideration -- including age, weight, diabetes and smoking conduct. Nevertheless, it's not possible to finish that tea, itself, merits the credit score, Coleman said. Other lifestyle factors are probably at work, she defined. And with eating regimen, Coleman mentioned, it is always tough to disentangle any consequences of a single meal or nutrient from the relaxation of a person's ingesting habits.

That stated, she pointed to some theoretical motives why tea can be beneficial. It includes a variety of plant chemical compounds that can combat irritation and guard frame cells from accruing damage. The findings have been published online Dec. 14 inside the British Journal of Ophthalmology.

For now, Coleman recommends focusing on a few confirmed steps.

The vital first step is to not take your eyes as a right, she stated. "cross in for that comprehensive eye examination."

Dr. Davinder Grover, a clinical spokesperson for the AAO, agreed.

He said humans need to get a "baseline" eye examination with an ophthalmologist at the age of forty -- a time whilst early symptoms of eye ailment can also begin to emerge. A few humans may additionally need to start earlier, Grover noted -- which includes people with family who developed glaucoma early, of their 40s or 50s.

As for prevention, there may be no surefire manner to keep off glaucoma. however human beings may additionally cut down the chance with the aid of minding their average fitness -- their cardiovascular fitness, specifically, he said.

"So when you have diabetes or high blood pressure, try to get that beneath manage," Grover said.

Coleman confused every other factor: even if glaucoma is already present, it could be dealt with -- with eye-drop medicinal drugs or laser surgical treatment, for example. that may save you harm to the optic nerve and imaginative and prescient loss.

Harm to the optic nerve isn't, but, reversible, Grover stated. So early detection and treatment are critical.

"The name of the game is prevention," Grover stated. "If we trap glaucoma early and deal with it correctly, the wide majority of the time, we win."
