Drinking green tea may help you keep slim, say scientists.
An extract from the tea was found to reduce the amount of starch – a type of carbohydrate – absorbed from food during meals. It means the drink could be used to help treat people suffering from obesity and diabetes.
Researchers gave 28 participants aged 19 to 28 a bowl of cornflakes to eat, having asked them to fast for the 12 hours before the test. They then asked them to eat a wafer – some of which contained around four grams of green tea extract, while others contained none. This was equivalent to drinking ‘several cups of green tea’, said researchers.
The scientists then tested participants’ breath for the presence of starch. When starch is broken down during digestion, the amount can be picked up by testing how much carbon dioxide is in the breath. Led by Jaroslaw Walkowiak of Poznan University in Poland, the researchers found the dose of green tea extract decreased starch digestion and absorption compared to the placebo group.
Writing in the journal Nature Scientific Reports, the study’s authors said: ‘This plant extract is widely available, inexpensive, and well tolerated, so it has potential utility for weight control and the treatment of diabetes.’
