title: The beneficial role of anti-inflammatory dietary ingredients in attenuating markers of chronic low-grade inflammation in aging.
abstract: Aging in humans is associated with chronic low-grade inflammation (systemic), and this condition is sometimes referred to as "inflammaging". In general, canines also age similarly to humans, and such aging is associated with a decline in mobility, joint problems, weakened muscles and bones, reduced lean body mass, cancer, increased dermatological problems, decline in cognitive ability, reduced energy, decreased immune function, decreased renal function, and urinary incontinence. Each of these conditions is also associated with an increase in pro-inflammatory cytokines. An inflammatory state characterized by an increase in pro-inflammatory markers including but not restricted to tumor necrosis factor-α, interleukin-6, IL-1β, and C-reactive protein (CRP) is believed to contribute to or worsen a general decline in biological mechanisms responsible for physical function with aging. Nutritional management of inflammation in aging dogs is important in maintaining health. In particular, natural botanicals have bioactive components that appear to have robust anti-inflammatory effects and, when included in the diet, may contribute to a reduction in inflammation. While there are scientific data to support the anti-inflammatory effects and the efficacy of such bioactive molecules from botanicals, the clinical data are limited and more studies are needed to validate the efficacy of these ingredients. This review will summarize the role of dietary ingredients in reducing inflammatory molecules as well as review the evidence available to support the role of diet and nutrition in reducing chronic low-grade systemic inflammation in animal and human studies with a special reference to canines, where possible.
