Influence of Bioactive Components of the Mediterranean Diet on Inflammation and Healthy Aging

Abstract

The Mediterranean diet is characterized by an increased consumption of fruits, vegetables, grains, and fish. Olive oil and herbs and spices are also essential components of this food regimen. Such a diet is associated with a reduced risk of cardiovascular disease, overall mortality, reduced incidence of Parkinson’s and Alzheimer’s diseases, and reduced cognitive impairment. Some of the bioactive components that exert beneficial effects are ω-3 fatty acids, polyphenols, and alkaloids that have neuroprotective, anti-inflammatory, antioxidant, antimicrobial, and gluco-regulating properties. These beneficial effects contribute to improved health including organ health and cognitive function. While the number of such bioactive plant constituents is numerous, this review will examine the role of specific bioactives and vitamins and assess the molecular mechanisms including the antioxidant and anti-inflammatory beneficial effects of the bioactive components in the Mediterranean diet.
