It is one of the main causes of blindness around the world and at the moment has an effect on 57.5 million people today, despite the fact that it is anticipated to maximize to 65.5 million by 2020. Earlier research suggests that caffeine can change intraocular force, but no analyze has so considerably when compared the likely influence of decaffeinated and caffeinated beverages on the risk of glaucoma, stories Europa Press.
Then, a team of researchers analyzed details from the Countrywide Wellness and Nourishment Survey (NHANES, for its acronym in English) 2005-2006 in the United States.

But tea contains antioxidants and anti-inflammatory and neuroprotective chemicals, which have been related with a reduced possibility of really serious disorders, which contain coronary heart illness, most cancers and diabetes, in accordance to experts. Former analysis proposed that oxidation and neurodegeneration might be associated in the growth of glaucoma and conclude: “A lot more study is needed to establish the relevance of these findings and no matter if the intake of scorching tea may engage in a purpose in the prevention of glaucoma.”.
