Type 2 diabetes: Properties found in green tea reduces major risks of the condition

Written by Administrator

Obesity and type 2 diabetes are major public health issues worldwide, contributing to increased cardiovascular morbidity and mortality. The proportions of people with obesity and/or type 2 diabetes have increased and recently reached epidemic levels. Incorporating green tea into your diet could help to lower your blood sugar levels.

Scientists from the University of Goias in Brazil looked at how green tea and diabetes drug, metformin, worked on 120 non-diabetic overweight women.

They concluded that green tea was “superior” to metformin in improving blood sugar control in women at risk for developing the condition.

Writing in the journal Clinical Nutrition ESPEN, they said: “Green tea extract is a promising alternative for reducing type 2 diabetes risk in overweight women.”

For people already diagnosed with type 2 diabetes, green tea may be able to help manage blood sugar levels.

In a study published in the US National Library of Medicine National Institutes of Health, the effects of green tea on obesity and type 2 diabetes were investigated. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3689013/

The study noted: “Green tea (Camellia sinensis) is one of the world’s most popular beverages, especially in Asian countries including Korea, China, and Japan.

“Because of the high rate of green tea consumption in these populations, even small effects on an individual basis could have a large public health impact.

“Various studies have shown the beneficial effects of green tea, not only on cardiovascular diseases but also on obesity and type 2 diabetes itself.

“In a retrospective cohort study performed in Japan, a 33 percent risk reduction of developing type 2 diabetes was found in subjects consuming six or more cups of green tea daily compared to those consuming less than one cup per week.”

Type 2 diabetes affects almost one in ten adults in the UK and costs the NHS around £14billion a year to treat.

More than four million Britons have type 2 diabetes and another 12 million are at risk of developing the condition.

Diet and exercise are key when it comes to reducing the risk of the condition.

Aiming for at least 150 minutes of physical activities with a diet of fresh fruit and vegetables will help lower blood sugar.
