Grape powder consumption affects the expression of neurodegeneration-related brain proteins in rats chronically fed a high-fructose-high-fat diet
Abnormal glucose metabolism in the brain is recognized to be associated with cognitive decline. Because grapes are rich in polyphenols that produce antioxidative and blood sugar-lowering effects, we investigated how grape consumption affects the expression and/or phosphorylation of neurodegeneration-related brain proteins in aged rats fed a high-fructose-high-fat (HFHF) diet. Wistar rats were maintained on the HFHF diet from the age of 8 weeks to 66 weeks, and then on a HFHF diet containing either 3% or 6% grape powder as an intervention for 12 weeks.
