Nuts are not allowed on induction... nut butters therefore are not either. When you are through induction - peanut butter and other nut butters are great additions (in moderation) but I would encourage you to get natural style nut butters - just nuts and salt. You have to stir them upon opening (the oil separates) and then refrigerate... but they are MUCH better for you - as the other kinds have transfats to keep them all nicely mixed all the time. Unfortunately the transfats are killers. Dr. A specifically addresses that we should avoid hydrogenated fats (trans fats).
