Butter is real food.
By contrast margarine is a fake food. It order to make margarine it must be processed so that refined vegetable oils are solid at room temperature. A yellow dye is added so that it looks like butter. It is synthetic, not real. The chemical intervention by modern food processors changes the nature of the food.
Some of the methods of processing oils to create margarine have changed so they don't create trans fatty acids but the fact is they are still processed. The vegetable oils have been refined using unhealthy methods.
