Good thought. But as has been said, expensive. Olive oil, parified butter are about the same callories (~250 per ounce) and easy to add to foods. Parified butter squirted into cocoa, oatmeal, on baked foods, etc. works well. Olive oil in soups, stews, fresh baked bannocks, etc. goes as well without the "burps."
3 or 4 per day will help with cholesterol, if that is a problem.
