Casein is the protein found in milk.

Tomato sauce and tomato paste are not waste products, and are from a plant.

Cow milk and cow milk products contain the IGF-1 hormone. Casein is a protein,yes and is glue. Body builders supplement with whey because it is cheap, the dairy industry needed to dispose of it, and they were scammed into thinking it is a good thing.

We need more plant based foods to save our planet and our lives.
