Protein is already being advertised to you on pretty much every food and drink product you see at the supermarket, and now Starbucks is going to make sure you get your fill at the coffee shop, too. Until now, Starbucks has been content to provide protein boxes of cheeses and eggs for its customers, but it seems the protein trend is too big to keep undrinkable. In the past decade, high-protein products have quadrupled in sales, partially due to fitness and wellness influencers pumping up the importance of high-protein ingredients for a healthy diet. This has led to a deluge of products, with everything from chips to breakfast cereals to ice cream advertising high protein content, and now ending with its inevitable form: a new Starbucks menu option.
