Bananas in Smoothies Destroy Polyphenol Benefits from Blueberries Study Shows

What was said

"There's something in the banana called polyphenol oxidase. That doesn't sound good. Doesn't sound good. Polyphenol oxidase, it's essentially an enzyme that's breaking down the polyphenols. And there have now been studies that have come out showing if you add bananas to blueberries, you're not getting as many polyphenols. In fact, it's quite a bit lower."

Dr. Patrick revealed new research showing that bananas contain an enzyme called polyphenol oxidase that significantly reduces the absorption of beneficial polyphenols from blueberries when combined in smoothies. She recommended replacing bananas with avocado, which provides creaminess while actually increasing absorption of nutrients from leafy greens by fourfold due to its healthy fats.
