🫐🍌 Could Your “Healthy” Smoothie Be Canceling Out Some of Its Own Benefits?
Most people think adding more fruit always makes a smoothie healthier.
But science says it’s not just WHAT you eat… it’s WHAT you eat TOGETHER.
A fascinating study published in Food & Function found that adding just one banana to a smoothie rich in berries dramatically reduced the body’s absorption of beneficial compounds called flavanols.
Why?
Bananas contain an enzyme called polyphenol oxidase (PPO)—the same enzyme that causes a banana to turn brown after it’s peeled. Researchers found this enzyme rapidly breaks down flavanols, reducing their absorption by about 84% compared to a berry smoothie or a flavanol capsule.
Why should you care?
Flavanols have been associated with supporting:
❤️ Healthy blood vessels
🧠 Brain function and cognition
🔥 Healthy inflammatory balance
🩸 Cardiovascular health
This doesn’t mean bananas are unhealthy—they’re still an excellent source of potassium, fiber, vitamin B6, and natural carbohydrates.
It simply means your food combinations matter.
✅ If your goal is maximizing flavanol intake from:
• Blueberries
• Blackberries
• Apples
• Cocoa
• Green tea
…consider blending them with lower-PPO fruits like:
🍍 Pineapple
🍊 Orange
🥭 Mango
…and enjoy your banana as a snack later.
Sometimes better nutrition isn’t about eating more—it’s about combining foods more intelligently.

Study note: The research was well-controlled but involved a small number of participants, so larger independent studies are still needed to determine the long-term clinical impact.
