Does Berries actually make a difference, or is it overhyped?

Most of the available literature for this topic centers on resveratrol, a polyphenol found in berries (and grapes), covering effects on health, skin, and bone density, including one randomized trial showing improved bone mineral density in postmenopausal women. Weighing the data: Berries looks an early-stage, lower-priority area for now — the evidence is only moderate (48/100), and its estimated impact (25/100) is on the lower end too.
