May improve memory, attention, and mood

Grapes may improve memory and brain health. Taking 250 mg of a grape supplement daily for 12 weeks increased results on a test evaluating attention, memory, and language in 111 healthy older persons, relative to baseline levels. Another research on healthy young people found that consuming 7.8 ounces (230 mL) of grape juice for 20 minutes increased both mood and the speed of memory-related tasks.

Furthermore, in mouse research, 4 weeks of resveratrol consumption enhanced learning, memory, and mood. Furthermore, the rats' brains showed indicators of enhanced development and blood flow. Finally, resveratrol may help prevent Alzheimer's disease by lowering brain inflammation and eliminating amyloid-beta peptide, which has been related to the illness. Grapes contain compounds that may improve memory, attention, and mood, as well as protect against Alzheimer’s disease.
