Minerals Aren't Destroyed By Heat
Minerals in milk are salts and do not degrade at pasteurization temperatures used in industry.
Claims that pasteurization 'damages all minerals' are scientifically unfounded.

Targeted Kill: How Pasteurization Works
Pasteurization heats every part of milk to a controlled temperature for a set time to denature pathogenic bacterial proteins.
This reduces disease risk while leaving most milk components largely intact.

Proteins Folded By Intermolecular Forces
Proteins are amino‑acid chains folded by intermolecular forces like hydrogen bonds into functional shapes.
Heat or acid breaks those forces and denatures proteins, destroying their original function.
