You can think that, but I don't agree. When entire stores pop up around products which, the majority they're selling have labeling highlighting protein content, it's not marketing? And if some, or many, of those products are filling said products with low quality / cheap protein that's not a gimmick? Not all protein is the same. I'd say there's plenty of marketing gimmicks around protein. Case in point... Check out GNC's website. Open the source. As of writing this, on the front page, protein is called out 98 times. Fiber? 4. Nutrition? 6. Search products on their site... When searching for protein it shows 1004 products. Fiber? 31. Nutrition? 304. I'm sure that the Ghost Whey Protein powder [0] that tastes like Chips Ahoy cookies - isn't a gimmick at all. But, what do I know? Feel free to share with me any studies highlighting the rampant protein deficiency epidemic in the west. I'd love to read them.
