Marshmallows have been around for thousands of years, with ancient Egyptians using the sap of the marshmallow plant to make a sweet treat. The modern marshmallow was invented in the 19th century, and it's been a favorite snack ever since. But with the rise of food allergies, it's become more important to know what's in our food, including marshmallows.
So, why do some marshmallows contain soy? It's because soy protein and soy lecithin are common ingredients in many foods, including marshmallows. They help to improve texture and extend shelf life. But for people with soy allergies, it's crucial to read labels carefully to avoid any potential allergic reactions.
