Polyphenols slow brain aging by improving blood sugar control. In a new study, people who

Partially SupportedGlucose control is a modifiable risk factor for cognitive decline, and high-normal glucose levels are associated with hippocampal atrophy.

Partially SupportedA polyphenol-rich green shake and green tea, as part of a low-calorie Mediterranean diet, slowed brain atrophy and improved glycemic control more than a Mediterranean diet or a healthy control diet lower in polyphenols.

Partially SupportedConsumption of polyphenol-rich foods was independently associated with brain and metabolic benefits.

Partially SupportedPolyphenols provide an additive benefit in attenuating neurodegeneration, which is significantly influenced by glucose control.
