If you love tea, keep on sipping the beverage, as it has many benefits for your health. A recent study discovered a new advantage for tea drinkers. Consuming the brew regularly is associated with a smaller risk of glaucoma, a condition which might lead to blindness.
Glaucoma is among the most popular causes of blindness
If the fluid present in your eye starts putting too much pressure on your optic nerve, you might suffer vision impairment. This is glaucoma, and it represents one of the main causes of blindness in the world. A team of researchers from Brown University and the University of California decided to look at the most recent data on the disease, and identify the correlations it holds with different factors.
For this study, researchers designed special interviews for the participants, where they questioned them on their consumption of coffee, soft drinks, iced and hot tea. Then, they performed some examinations of their health condition. The study collected over 10,000 people, but 1,678 of them could provide information on the consumption of these beverages.
Caffeinated tea protects your vision
By comparing the results regarding the beverages and the eye tests, they discovered that 5 percent of the 1,678 people developed glaucoma. Those who drank one cup of hot tea per day had a 74 percent smaller chance of developing the eye condition. Of course, the researchers had accounted for other factors which could have influenced the disease.
However, this correlation was viable only in the case of caffeinated tea. Other drinks, including decaf tea, were not related with the glaucoma risk. However, the study comes with several limitations. It didn’t account for the type, quantity, and method of brewing used by the participants. Also, the methods used for testing are a bit too statistical in nature.
