Dietary polyphenols prevent and manage Type 2 diabetes mellitus through insulin-dependent mechanisms (protection of pancreatic islet β-cells, reduction of apoptosis, promotion of proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of insulin secretion) and insulin-independent mechanisms (inhibition of glucose absorption, inhibition of digestive enzymes, regulation of intestinal microbiota, modification of inflammation response, and inhibition of advanced glycation end products formation).

Incorporate polyphenol-rich foods (like berries, tea, coffee, and wine) into your diet as part of a broader strategy for managing Type 2 Diabetes. Do not rely on isolated polyphenol supplements as a substitute for prescribed medication, as clinical evidence for their standalone therapeutic effect is currently limited.

Dietary polyphenols prevent and manage Type 2 diabetes mellitus via the insulin-dependent approaches, for instance, protection of pancreatic islet 𝛽-cell, reduction of 𝛽-cell apoptosis, promotion of 𝛽-cell proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of pancreas to secrete insulin, as well as the insulin-independent approaches including inhibition of glucose absorption, inhibition of digestive enzymes, regulation of intestinal microbiota, modification of inflammation response, and inhibition of the formation of advanced glycation end products.

Why this rating

The paper is a review highlighting advances; it cites numerous in vivo/in vitro studies but explicitly states clinical data is 'very limited' and 'individual flavoid... has no therapeutic effect on diabetic patients'.
