METHODS: In the pre-clinical phase, Swiss mice were divided into six groups and subjected to malnutrition and renutrition. The clinical phase was carried out with 25 elderly women residing in a long-term institution, aged ≥ 65 years and with malnutrition or risk of malnutrition. RESULTS: The main results showed improvements in anthropometric parameters and an increase in serum albumin levels, in addition to lipid profile improvement in the preclinical phase and an increase in the red blood cells and hemoglobin in the clinical phase. CONCLUSION: The supplement based on Buriti was able to reverse malnutrition promoting improvements in anthropometric and biochemical parameters.
