Again, vegans almost always have to read the ingredients/labels, on every processed food product they plan to consume. The little 'vegan' icon on the back is new and not consistently used. Choosing a plant based lifestyle is A LOT more burdensome than not doing that. I know because I've switched back and forth many times and am married to a vegan. Whey, casein, random cream, honey, they're in everything.

Even so: reading ingredients is honestly not that hard.
