Lard is very much food, it has been a staple of many cultures diets for a long, long time. People here in Central Europe spread it on top of sourdough bread and top with sliced leeks.
I'm with you on refined sugar, though, which is what I think you probably meant by raw sugar.
Not only are raw sugar and lard considered food, but they're better for you than refined sugar and refined plant oils. Of course, as with everything, the poison is in the dose.
Go to the supermarket and only buy things with one ingredient, cook and eat those things.
What qualifies? Vegetables, fruit, rice, beans, meat, etc.
ONE ingredient only.
(Technically raw sugar or lard qualify to be on my list, but I think most people who passed high school know those aren't food)
EDIT: well, yes raw sugar and lard are food, what I meant was you shouldn't be eating either in large quantities.
