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.

    Careful with tuna. It’s an important part of my diet as well but I try to mix it up because of heavy metals.

      Yes, you really shouldn’t eat tuna more than like 2-3 times a week because of the mercury content.
