evidence: True or False: The colored stripe at the edge of your toothpaste tube is a secret way to tell what ingredients are really in your toothpaste despite what the ingredient panel tells you. [...] You would be right; this is false with a capital F. Chalk this up to another online urban legend that’s been circulating around the internet for quite some time. If you haven’t heard about this hidden, top-secret code, the basic gist is that the stripe on your toothpaste tube is color coded to secretly tell the user what’s in the product, and if it’s healthy or not. [...] The fact of the matter is that the colored stripes on the tubes have absolutely nothing to do with the ingredients. Colored stripes are also not limited to just toothpaste tubes. If you check your fridge and cupboards, you’ll see them on products like milk cartons and cereal boxes.
