Is Kombucha Any Healthier Than Other Fermented Foods?

Is Kombucha Any Healthier Than Other Fermented Foods?

Kombucha is an ancient Chinese brew that, until recently, many people in the U.S. hadn't even heard of. It's a fermented drink that's made from tea, sugar and a glob of yeast and bacteria called a SCOBY (symbiotic cultures of bacteria and yeasts). Kombucha has become one of the top-selling fermented drinks — in 2015, supermarkets sold about $180 million worth.

What does SCOBY do? The supposed benefits of kombucha include lowering blood pressure and lousy cholesterol, KO-ing bacteria, promoting heart health, fighting cancer and easing gastric problems. But does it really deliver?

Research shows it's hard to know what you are getting when you buy it—or make it at home (folks do). Its "powers" change depending on the tea leaf, sugar content, fermentation time and the composition of the SCOBY that's used. However, researchers do say it may provide the same benefits as drinking tea and eating fermented foods—including improved digestion and a healthier gut biome. As for other claims, extensive reviews of available kombucha studies show "benefits" were found in lab animals—not in humans.

Also, Blue Cross Blue Shield, cautions: "it naturally contains minor amounts of alcohol, so it's best to avoid drinking kombucha if you're pregnant or breastfeeding." And the Cleveland Clinic explains that while the CDC recommends limiting intake to 12 ounces a day—most commercially sold bottles contain much more. Bottom line: Don't gulp it down. And consider enjoying a cuppa tea and yogurt instead.

How to Safely Make Lifestyle Changes With Type 2 Diabetes

Gain control of your disease while still protecting your heart

If you're overweight or obese and have type 2 diabetes, a new study reveals how to make lifestyle changes that will help you safely gain control of your disease and still protect your heart.

Researchers published a study in Diabetes Care that took a second — and more in-depth — look at data from the NIH's Look AHEAD study. They found that for 85% of people in that study, lifestyle interventions that triggered weight loss and increased physical activity reduced potential cardiovascular problems. Such lifestyle interventions also help reduce the risks for diabetes, dementia and some cancers and strengthen the immune system.
