Popcorn is one of exceedingly few choices for gluten-free, whole-grain snack foods out there.
Being a Whole Grain, it contains the germ portion of the seed which is where the protein is found, as well as part of the hull which is where the fiber is found. A complete little package created by nature that packs a crunchy punch; without having to process, isolate, modify, or separate anything out of it. Just apply heat and… pop, there’s your food. Simple and good.
