Cellular senescence is a state of irreversible growth arrest characterized by hypertrophy and secretion of various bioactive molecules, a phenomenon defined the Senescence-Associated Secretory Phenotype (SASP). Senescent cells are implicated in a number of biological functions, from embryogenesis to aging. Significantly, excessive accumulation of senescent cells is associated to a decline of regenerative capacity and chronic inflammation. In accordance, the removal of senescent cells is sufficient to delay several pathologies and promote healthspan. Calorie restriction (CR) without malnutrition is currently the most effective non-genetic intervention to delay aging phenotypes. Recently, we have shown that CR can prevent accumulation of senescent cells in both mice and humans. Here, we summarize the current knowledge on the molecular and cellular events associated with CR, and define how these events can interfere with the induction of cellular senescence. We discuss the potential side effects of preventing senescence, and the possible alternative dietary interventions with potential senolytic properties.
