It’s hard enough to avoid GMO foods when there are no laws requiring the labeling of them, but it’s harder once you learn that other common ingredients may be manufactured from GMOs. For example: if you see maltodextrin in the list of a product’s ingredients, know that most of that is made from GMO corn (unless the product is labeled as “USDA Organic”). Vitamin C is another GMO corn product (mostly). Same with ascorbic acid. Will these GMO products cause you harm? That’s the big question, and frankly until the scientific testing has been done to show that a particular GMO crop is safe to eat, it’s best to avoid this stuff (IMHO).
