The study wsa actually about anthocyanins and flavones [types of flavonoids] but I like the heading.

Researchers say compounds in red wine guard against type 2 diabetes



According to a study of 2,000 women in the UK, plant compounds called flavonoids that are present in some berries and fruit – and in chocolate and red wine – protect against the disease of glucose metabolism.

The research is likely to be seized upon by the sugar industry, which on Monday struck out against being “demonised” by pressure groups.

The study at the University of East Anglia published in the Journal of Nutrition, is one of the largest scientific investigations of the effects of flavonoids on type 2 diabetes, which affects more than 2m people in Britain.

The researchers analysed blood samples and monitored the food consumption of 2,000 healthy volunteers.

“We found that those who consumed plenty of anthocyanins and flavones [types of flavonoids] had lower insulin resistance,” said Professor Aedin Cassidy, the research leader. “High insulin resistance is associated with type 2 diabetes, so what we are seeing is that people who eat foods rich in these two compounds – such as berries, herbs, red grapes, wine – are less likely to develop the disease.”

The biochemical mechanisms behind the findings are unclear, though the researchers suspect that flavonoids raise levels of a protein called adiponectin, which regulates glucose metabolism.
