But they may not be vegan.
I say “may” because Frosted Flakes has a few ingredients that strict vegans avoid, but some vegans are okay with.
I’ll lay out the arguments for and against them, and you’ll have to decide for yourself.
Frosted Flake Ingredients
Here’s what you’ll find in Frosted Flakes:
Milled corn, sugar, malt flavor, iron, niacinamide, vitamin B6, vitamin B2, vitamin B1, folic acid, vitamin D3, vitamin B12
For the most part, it looks okay.
But I highlighted 2 ingredients that vegans should pay attention to.
Why Vitamin D3 Isn’t Vegan
Most vitamins added to foods like cereal are synthetic and vegan, but vitamin D3 is the exception.
I wrote a more detailed post to why vitamin D3 isn’t vegan, but the gist of it is that the easiest source to get it is from lanolin (the grease from sheep’s wool).
This is not vegan, and it’s why Frosted Flakes are technically not vegan.
But some vegans are still okay with eating them. Why?
That’s because there’s literally only micrograms of the D3 added. Some vegans feel it’s unreasonable to avoid such a small amount.
You’ll have to decide for yourself.
Why Sugar Might Not Be Vegan?
So let’s say you’re okay with the vitamin D3 here, that leaves us with the sugar.
White sugar in North America is often filtered with bone char to make it as white as possible. This sugar is not vegan.
So when you see “sugar” on a product that was made in North America, you don’t know whether or not it’s vegan. It might be, but it might not.
With large companies like Kellogg’s, I tend to assume it’s not vegan, as they usually have multiple sugar suppliers, and there’s a good chance that at least one uses bone char.
However, if you’re okay with taking that risk, then you may be fine with eating Frosted Flakes, even though they are technically not vegan.
Ultimately, you need to remember that there’s not a single definition of veganism that everyone agrees on. Sure, there are the obvious things, but there are many gray areas like these that you’ll need to decide on yourself in a way that you can feel good about your choices.
