People who are overweight or eat a high-fat diet are the most likely to benefit. Tea has long been linked to good health. But earlier this year a study confirmed it lowers cholesterol and blood pressure — key risk factors for heart disease and stroke — while another showed it protects the brain and reduces the risk of dementia. Now research reveals the UK nation’s favorite drink gives immunity a lift by rebalancing bacteria that live in our gut.
The human body is home to trillions of microbes which are so important for health that scientists have likened them to a second immune system, Iran News covers the story that expressco wrote about tea benefits.
Researchers analyzed results from 24 trials and found that tea drinkers have higher levels of “friendly bacteria” that protect against health problems and fewer firmicutes — microbes linked to increased risk of obesity, diabetes and inflammation. Firmicutes play a key role in extracting energy from food, and we are more likely to gain weight if their levels are high.
The study, published in the journal Nutrients, looks mostly at green tea but the black tea most commonly consumed in the UK shows similar benefits.
One of the researchers, Dr. Tim Bond from the Tea Advisory Panel, said: “This is still an area of emerging science, but the potential implications for health are enormous.
“We know the gut biome has a much greater impact on our health than we had previously considered possible, and when the balance of bacteria in our gut is out of kilter it disrupts the way we metabolize fat and sugar and increases inflammation.
“There is now a growing body of evidence to suggest that drinking tea can go a long way towards restoring a healthy balance of gut bacteria and, by doing this, support our immune system and protect against disease.
“Everyone knows that fiber or probiotics can help change gut bacteria towards more favorable strains, but it was a pleasant surprise to discover that a simple cup of tea can also be effective.”
