10. Stick margarine
Margarine was long heralded as a healthy alternative to butter, but we know now that this claim is the exact opposite of the truth. Margarine is full of trans fats, which carry with them all sorts of negative health implications. It’s also a totally processed product, whereas butter is natural. While some brands of margarine in tubs are free of trans fats and are at least somewhat better for you, stick margarine is still full of them. If you’re making recipes that call for butter, use butter rather than this artificial version.
