Cheerios lovers, brace yourselves: three flavors are gone — here’s why.

Cereal lovers beware: You may not like what you are about to read.

General Mills, the maker of popular breakfast cereal, Cheerios, has sadly decided to discontinue three of its flavors: Honey Nut Cheerios Medley Oat Crunch, Chocolate Peanut Butter Cheerios and Honey Nut Cheerios Minis. Didn’t know there was more than one kind of Cheerios? Here are all the flavors, from Fruity Cheerios, and Pumpkin Spice Cheerios—to Very Berry.

So, while this may be bad news for cereal junkies everywhere, there is a silver lining here. It turns out the reason they are taking them off the shelf is to make way for some new offerings including, the Cheerios Protein line.

“As we’ve introduced new innovations this year—including Cheerios Protein, available in Cinnamon, Strawberry and Cookies and Creme, Cheerios Oat Crunch Chocolate, and the return of fan-favorite Frosted Lemon Cheerios for a limited time this summer—we have discontinued a few products from our portfolio,” General Mills told Fast Company in an emailed statement.

If you are wondering if there is any hope of resurrecting one of those three discontinued flavors, fear not.

“Much like Frosted Lemon Cheerios, which returned by popular demand, we continue to listen to our fans as we evolve our offerings,” General Mills added.

Cheerios isn’t the only company jumping on the high protein bandwagon, also known as protein-maxxing. They join a number of other food and beverage brands, including Starbucks, who recently announced the addition of a new Protein Cold Foam that adds a whopping 15 grams of protein to each coffee drink.
