Peanut Consumption on Cognitive Performance, Weight Management, and Inflammation in Young Adolescents
Source: ClinicalTrials.gov · Last updated 4 Sept 2026
Brief summary (registry, in English)
A multi-school, two-arm parallel cluster-randomized controlled trial will be conducted in 200 healthy young adolescents from Barcelona (Spain) to evaluate the effect of peanut consumption on cognitive performance, weight management and inflammation. Schools willing to participate will be randomly assigned to either the intervention or the control group. After the recruitment, the participants will follow a peanut-free diet for two weeks. Both arms will receive a multidimensional educational intervention designed by the Gasol Foundation to promote healthy dietary habits based on Mediterranean diet recommendations, along with exercise performance, healthy sleeping habits and emotional knowledge. Half of the participants (intervention group) will consume 25 g of whole skin roasted peanuts as a daily snack to be incorporated into their diet for six months.
