Is there a huge difference between regular peanut butter and natural peanut butter?
Peanut butter today is remarkably like that made 100 years ago. All peanut butter must, by law, contain a minimum of 90% peanuts. Both natural and regular peanut butters may contain some sugar and salt for flavoring. Some brands also contain a small amount of stabilizer (partially hydrogenated vegetable oil) to keep the oil from separating, which most consumers prefer. This also helps maintain peanut butter freshness.
