New research helps maximize the health benefits of fruit smoothies. Smoothies offer a delicious and easy method to incorporate essential fruits and vegetables into your diet. But is a banana and blueberry smoothie the best combo? New research from the University of California, Davis, suggests that

Researchers have found that the enzyme polyphenol oxidase (PPO) in certain fruits like bananas can reduce the absorption of heart-healthy flavanols, especially when combined with flavanol-rich ingredients like berries. The study suggests choosing ingredients with low PPO activity, such as pineapple or oranges, when making smoothies to optimize flavanol absorption.

    So basically, just add a bit of lemon juice to your smoothie?

      I’m not confident saying for sure without reading the actual paper - it really depends on how PPO interacts with the flavanols, but at the end of the day denaturing the PPO with heat should make it a non-issue. Keep in mind though that bananas are far from the only smoothie ingredient with PPO!
