Cheerios!

Ah, the mighty Cheerio!

First introduced in May of 1941, this General Mills' product quickly became a staple of the American breakfast table. 

Over the decades, various flavors have come and gone. The third product iteration, Honey Nut Cheerios, was launched in 1979. Coated with a brown sugar-molasses-honey glaze, this version is second only to the original in popularity. 

But perhaps the biggest uptick in recent sales is due to the "o" in Cheerios. Made from oats, Cheerios were officially certified gluten-free in 2015 after factories in the United States removed traces of rye, barley, and wheat that had previously contaminated the supply chain. That said, be sure to check the label when you venture abroad. Cheerios manufactured by Nestles, like in the UK, still contain wheat!
