Here’s something to choke on. The “blueberries” inside that muffin or cereal you love so much might not actually have ever been blueberries. Instead, they are a composite of sugars and starches that have been dyed blue. Check the label. If it says “blueberry flavored chrunchlets,” for instance, those are actually sugars, soybean oil, red #40 and blue #2. Reached for comment, Kellogg’s told NPR that the stuff is “labeled in compliance with applicable laws and regulations.” Well that takes care of that. If it’s not illegal and is profitable, do it.
