Surprising research reveals why you shouldn't add bananas to your smoothies
Recent research indicates that adding bananas to berry smoothies may significantly hinder the absorption of beneficial flavanols. The study found that bananas, which contain high levels of the enzyme polyphenol oxidase, can reduce flavanol levels by up to 84% compared to smoothies without bananas. This highlights the importance of food combinations in maximizing nutritional benefits.
- ▪Adding bananas to berry smoothies can dramatically reduce the body's ability to absorb healthy flavanols.
- ▪Participants who drank banana smoothies had 84% lower flavanol levels compared to those who consumed a control capsule.
- ▪Researchers recommend pairing flavanol-rich fruits with low PPO ingredients like pineapple or yogurt for better nutrient absorption.
