contains powerful antioxidants, and some research suggests that drinking relatively large amounts of it — the equivalent of about five cups daily — may help prevent or delay cataract development. One animal study tested the power of tea in diabetic lab rats (the scientists used diabetic rats because they were at increased risk for cataract formation). Rats that were given tea had about half the risk of cataracts as the rats who didn't drink tea. We're still waiting to see if these results hold up in people, but tea is an incredibly healthy drink all around — and unsweetened, it's a terrific substitute for sugary beverages like soda, fruit drinks, and sugary coffee concoctions — so I encourage you to sip both green and regular black tea
to your heart's content.
