One of the faster growing segments of the beverage market are so called super berry drinks. They include fruits such as pomegranate, acai, and goji and they're available in almost any supermarket. These drinks are sold as powerful anti-oxidants with benefits to the heart. But a quick google search reveals the benefits don't stop there. Marketers claim the Acai berry can do everything from improve your skin, to help you lose weight. But for a lot of these drinks, the marketing is years ahead of the research. For this week's Tuesday Checkup, ideastream®'s Eric Wellman went to Dave's supermarket near downtown Cleveland where he met Plain Dealer reporter Brie Zeltner. She writes about these super berries in the health section of the Plain Dealer.
