"Smoothie Ingredients' Nutrient Interference Uncovered in Study"

New research suggests that combining bananas with berries in smoothies may decrease the health benefits of certain ingredients. The study found that smoothies containing bananas and berries resulted in a decrease in flavanols, a key nutrient in berries. Flavanols are linked to potential health benefits such as lowering blood pressure and promoting healthy brain function. The chemical reaction between bananas and air releases polyphenol oxidase (PPO), which affects the bioavailability of flavanols. To maximize the nutrient content of smoothies, experts recommend using low-PPO fruits like pineapple, oranges, mango, and yogurt, and consuming the smoothie soon after preparation. However, it's important to maintain a well-rounded diet with a variety of proteins, grains, healthy fats, and fruits and vegetables to ensure overall nutritional balance.
