These beneficial effects of green tea could be due to its powerful antioxidant epigallocatechin gallate (EGCG), which many studies have found to increase insulin sensitivity.
General lifestyle tips to improve insulin sensivity
To optimise the benefits of drinking green tea, it is important to commit to an overall healthy lifestyle.
According to Diabetes.co.uk, you should choose foods with higher fibre and a lower GI and glycemic load to help improve insulin sensitivity.
The glycaemic index (GI) is a rating system for foods containing carbohydrates – it shows how quickly each food affects your blood sugar (glucose) level when that food is eaten on its own.
“Combining aerobic activities with resistance training has been shown to be an effective way to increase insulin sensitivity,” says the health body.
It adds: “As well as performing physical activity, losing excess body fat can help to improve insulin sensitivity.”
