“…Several studies have shown that a reduction in the dietary fat intake and changes in the relationship n-6/n-3 produce changes in the immune response (Kew et al, 2003). The use of nutritional supplements rich in n-3 LCPUFA is associated with a reduced activity and plasma levels of circulating immune cells (lymphocytes, polymorph nuclear neutrophils and monocytes), including the reduction in the production of inflammatory mediators (Weinstock-Guttman et al, 2005;Nordvik et al, 2000). Moreover, a reduction in the intake of n-3 LCPUFA improves a number of indexes associated with the immune response, including lymphocyte proliferation, increased macrophage activity and cytokine production (Serhan et al, 2000).…”
