Researchers found that adding bananas to berry smoothies can significantly reduce the absorption of beneficial compounds called flavanols. These compounds are linked to heart and brain health and are abundant in foods like berries, apples, and cocoa. The study from the University of California, Davis, highlights how food combinations can impact the nutritional benefits you receive, even from seemingly healthy drinks.

For those looking to age well, this discovery is important. Flavanols are recommended in daily amounts of 400 to 600 milligrams for optimal cardiovascular and cognitive health. If you enjoy smoothies and want to maximize flavanol intake, avoiding bananas when mixing with berries or other flavanol-rich foods may be wise. The research showed that participants who drank banana smoothies had 84% lower flavanol levels in their bodies compared to those who consumed a mixed berry smoothie.

The study involved a small group of healthy participants and was carefully designed, but it is still early-stage research. With only eight men in the first part and eleven in the second, the findings are intriguing but should not be generalized to everyone. Nutrition experts advise that while this study provides valuable insights, it’s essential to maintain a balanced diet and not to overreact. Smoothies with bananas can still be nutritious, especially when enjoyed as part of a varied diet.

To make a flavanol-friendly smoothie, consider pairing berries with low PPO ingredients like mango, pineapple, or yogurt. Bananas can still be included in your diet for their fiber and potassium, but if your goal is to boost flavanol intake, enjoy them separately or in different smoothie combinations.
