A cup of green tea is a good way to start your day.
“It’s the healthiest thing I can think of to drink,” says Christopher Ochner, PhD. He is a research scientist in nutrition at the Icahn School of Medicine at Mount Sinai. “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, and 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 toAlzheimer’s disease.
Green tea seems to help keep blood sugar stable in people with diabetes. Because catechins lower cholesterol and blood pressure, they can protect against the damage a high-fat diet can cause, Ochner says.
Green tea can help increase and even change your metabolism, so you burn more calories from fat. Studies show that green tea can also help you keep weight off once you’ve lost it.
It’s also a smart swap for sugary drinks. “All things being equal, if you sub 1-2 cups of green tea for one can of soda, over the next year you’d save over 50,000 calories,” says Ochner. That’s more than 15 pounds.
