You Can Thank A Whey Refinery For That Protein Smoothie

If you’ve ever checked the ingredient list on a PowerBar or a high-protein smoothie, you probably have stumbled across these words: “Whey protein concentrate.” You’ll find it in a growing number of prepared foods.

This mysterious ingredient is derived from one of the oldest of human foods — milk. But capturing it requires huge factories that look more like oil refineries than farms.

In fact, the refinery comparison is apt. Increasingly, milk isn’t something you just drink anymore — we’re drinking less plain old milk these days. Instead, milk’s become a raw material, sort of like crude oil, that’s broken down into separate, more valuable products.
