Dietary Control of Rumination: Two Case Studies

Chronic rumination of 2 institutionalized men with profound mental retardation was treated using a dietary approach. In the first case, a peanut butter or honey supplement was given, whereby 2 spoonfuls of either food was added to every meal, with drinks moved to a later time. In the second case, food satiation together with a honey supplement was applied. In the first case, an ABABACA design was used. In the second case, the non-experimental AB design was applied. In both cases, rapid decrease in rumination was achieved. Anecdotal follow-up confirmed the permanency of the results.
