Body composition modifications due to aging can bring many health issues. Systemic inflammation, possibly started in bowel or adipose tissue, seems to be importantly associated to these modifications. This study aims to test three hypothesis: a-) Modulation of bowel microbiota with symbiotic substances can improve the systemic inflammation pattern, minimizing the loss of free fat mass in elderly; b-) Modulation of intestinal permeability by the intake of a glutamine supplement can improve the loss of free fat mass in elderly; c-) A program of Nutritional Education can be enough to reduce the systemic inflammation and to improve body composition modifications in aging individuals, without the need of nutritional supplements. We intend to study 60 elderly individuals, submitting them to the following procedures: Double blind distribution in three different groups according to the intake of: - symbiotic substance; - glutamine; or - placebo. During the first month before the distribution in groups, and throughout the study, the participants will be submitted to nutrition education activities, weekly (during the first month) and each 15 days (from the second month onward). The participants will be evaluated at the start and at the end of the study, regarding to: anthropometric measures, body composition by DEXA and BIA, physical activity level, level of inflammatory cytokine, intestinal permeability, and food intake. At the end of the study, the results will be compared between groups and intra-groups (comparison between initial and final values) (AU)
