Habitual food intake and physical activity can affect chronic low-grade inflammation, which is common in the elderly, because of changes in the immune system and body composition. Thus, the present study proposes an evaluation of the influence of past eating habits on the effects of an intervention of resistance training plus dietary advice on the inflammatory profile of the elderly. We conducted an intervention study with 40 elderly people. The Revised Diet Quality Index (HEI-R) and the dietary total antioxidant capacity (dTAC) were calculated before the intervention based on a food frequency questionnaire validated to the elderly population. Participants were categorized according to the median of HEI-R and dTAC to assess the influence of the habitual diet quality on anthropometry and inflammatory markers (CRP, IL-8, CCL-2, and leptin) before and after the intervention. The 19-week intervention provided a long-term progressive resistance training associated with dietary advice focused on foods rich in compounds with anti-inflammatory and antioxidant properties. There was a greater reduction in weight, body mass index (BMI), and body fat (%) in the group with the lowest HEI-R and a greater reduction in the body fat (%) in the group with the lowest dTAC, indicating that the group that had a worse diet quality before the intervention responded better to it. The index HEI-R correlated negatively with Δweight and ΔBMI. dTAC correlated positively with Δmonocyte 1 chemotactic protein (CCL-2) and ΔC-reactive protein (CRP). In this scenario, elderly persons with bad habits can benefit from interventions to lifestyle change, while the better diet quality including dietary antioxidant sources can be useful to control weight and inflammatory biomarkers in this population.
