I'd read before that milk interferes with the absorption of catechins from green tea, but this study seems to suggest it’s proteins in general -
Antioxidant activity of blueberry fruit is impaired by association with milk
The first sentence of the abstract:
"The antioxidant properties of dietary phenolics are believed to be reduced in vivo because of their affinity for proteins."
Now I avoid milk and most dairy anyway, but this study seems to indicate it's not just casein that phenols tend to bind to.
I ingest most of my phenolic compounds (green tea, GSE, blueberries, Resv, etc.) either with my BCAA sup or with meals that are, typically, heavily protein. Am I doing it wrong?
