Olive Oil
Summary
This is a prospective, randomized controlled nutrition intervention trial to determine immunological impact of high olive oil consumption in elderly. Aging is associated with impaired immune response which contributes to higher incidence of infections in elderly. Previously the investigators have shown that the type of fatty acids in the diet influences the immune response. In particular, reducing consumption of fats high in n-6 fatty acids has been shown to improve the immune response in aged. Very few studies have evaluated the role of olive oil, the main oil consumed as part of the Mediterranean diet on the immune response of elderly. The investigators hypothesize that high olive oil consumption will improve immune function in elderly. In addition, the investigators will investigate the effect of high olive oil consumption on gene expression of relevant pathways in circulating mononuclear cells, as well as on cognitive function.
Primary Outcome
change in delayed hypersensitivity skin-test (DTH)
