ABSTRACT
Aging of the immune system, or immunosenescence, alters the viral immune response in the elderly, especially when frailty exists. Research findings have demonstrated an imbalance in pro- and anti-inflammatory mechanisms, reduced production and diversification of T lymphocytes, and an alteration in immunovigilance and antibody synthesis. In this context, nutrition has a role in combating sarcopenia and frailty. Some food components that contribute to immune-competence are protein, vitamin D, n-3 fatty acids, antioxidant vitamins (vitamins C and E), zinc, selenium and iron. In times of a pandemic, nutritional recommendations for immune-competence in the elderly should be based on clinical studies. In this article, immunosenescence and its relationship to nutrition are addressed, including interventions studied in the context of the COVID-19 pandemic.
