Peanut butter, it seems, is the basis of a “ready-to-use therapeutic food” (RUTF) for aiding recovery of severely malnourished children in Africa. The announcement of these results doesn’t say what kind. The study itself is published in Maternal and Child Nutrition and the authors make the point that people administering this RUTF do not need to be medically trained so this therapy can be used at home. I’m always amazed when researchers discover that feeding malnourished children helps them to recover. Peanut butter is highly concentrated in calories and the investigators mixed in some vitamins along with it, so I guess it can be considered a superfood.
