Green tea is so good for you that it’s even got researchers raving.
“It’s the healthiest thing I can think of to drink,” says Christopher Ochner, PhD. He’s a research scientist in nutrition at the Icahn School of Medicine at Mount Sinai Hospital. “Green tea is beyond a super food.”
In the past 20 years, thousands of studies have shown green tea’s benefits.
Why is green tea so good for you? “It’s all about the catechin content,” says Beth Reardon, RD, a Boston nutritionist. Catechins are antioxidants that fight and may even prevent cell damage. Green tea is not processed much before it is poured in your cup, so it is rich in catechins.
Green tea has been shown to improve blood flow and lower cholesterol. A 2013 review of many studies found green tea helped prevent a range of heart-related issues, from high blood pressure to congestive heart failure.
What’s good for the heart is usually good for the brain; your brain needs healthy blood vessels, too. In one Swiss study, MRIs revealed that people who drank green tea had greater activity in the working-memory area of their brains. Green tea has also been shown to help block the formation of plaques that are linked to Alzheimer’s disease.
Green tea seems to help keep blood sugar stable in people with diabetes. Because catechins lower cholesterol and blood pressure, they can help protect against the damage a high-fat diet can cause, Ochner says.
