Flavonoid-rich foods and drinks tied to an up to 28% lower risk of type 2 diabetes

  • New research has revealed that increasing the consumption of flavonoid-rich foods can significantly reduce the risk of developing type 2 diabetes.
  • This form of diabetes is a growing public health concern, affecting over 400 million people worldwide and contributing to over 1 million deaths annually, according to the World Health Organization (WHO).
  • Researchers analysed data from 113,097 participants in the UK Biobank, finding that a diet high in flavonoids, particularly from foods like berries, apples and tea, is linked to improved insulin sensitivity and reduced diabetes risk.

A new study, published in Nutrition & DiabetesTrusted Source, examined the connection between a flavonoid-rich diet and the onset of type 2 diabetes within a large population in the United Kingdom.

Adopting a diet rich in plant-based foods is already known to decrease the risk of type 2 diabetes. However, plants are abundant in various polyphenolic compounds that differ in their bioavailability and bioactivity.

Flavonoids, a category of polyphenolic compounds, are divided into six main subclasses: flavanones, flavones, flavan-3-ols, flavonols, anthocyanins, and isoflavones.

There is some evidence to suggest that a higher intake of flavonoids may lead to greater insulin sensitivityTrusted Source and an improved blood lipid profile.
