all this got me curious and looked it up. here are a few things that often contain palm oil: bread, margarine, some cheese, ice cream, soap & shampoo, chocolate, pre-made pizza etc.
looks to me like you might want to go back to making everything yourself or know every single brand around...
What breads and cheeses contain palm oil? Don't buy them, bread should have salt water yeast flour and cheese definitely should not have oil. Don't buy margarine either, prefer butter, olive oil, or vegetable oil.
There are loads of kinds of chocolate, including very affordable labels, that do not contain palm oil. Oil is an additive chocolate to cut down on the actual chocolate ingredients. Real chocolate shouldn't have it. Chocolate flavored candy has it.
You don't have to make everything from scratch you just have to avoid the worst of the worst processed junk.
