The Mediterranean diet (MedDiet) is an extensively studied dietary pattern which has been proposed as a lifestyle intervention to promote healthy aging in the general population, due to its numerous health benefits. Randomized controlled trials (RCTs) have attempted to explore the mechanism(s) by which the MedDiet exerts its beneficial effects on aging. One proposed mechanism is that the MedDiet helps to slow down a process called 'inflamm-aging', a type of chronic, low-grade inflammation which contributes to aging. To explore the evidence supporting this hypothesized mechanism, we conducted a scoping review of existing RCTs which used a MedDiet intervention and assessed at least one molecular outcome of potential relevance to inflamm-aging.
