The Claim
Casein binds to polyphenols through both non-covalent interactions (including hydrogen bonding, hydrophobic interactions, ionic bonding, and van der Waals forces) and covalent bonds formed via enzymatic or non-enzymatic oxidation, which results in alterations to casein's protein conformation and functional properties.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When casein (a protein in milk) meets polyphenols (natural compounds in tea, wine, or fruit), they stick together in different ways—like magnets and glue—and this changes the protein’s shape and how it works.

What the research says
1 studyThis study says that casein (a milk protein) sticks to polyphenols (found in tea, wine, etc.) using weak hugs and sometimes even forms permanent bonds when exposed to air or enzymes, which changes how the protein behaves—exactly what the claim says.
