Whey protein isolate is a highly processed, isolated powder made from the leftovers of cheese production. You're not getting the nutrient-dense benefits of whole milk or cheese, just a concentrated dose of protein stripped from its natural context. This is not food, it's a lab product.
Why trash
Industrially isolated dairy byproduct. Real food doesn't come in a tub with a scoop.
Try instead
Eggs, Greek yogurt, or cottage cheese
