Abstract
Purpose of review
As heart disease and type 2 diabetes mellitus (T2DM) cases continue to rise, identifying lifestyle modifications to prevent cardiometabolic disease (CMD) is urgently needed. Clinical evidence consistently shows that higher dietary or biomarker levels of linoleic acid (LA; 18:2n6) reduce metabolic syndrome (Mets) and reduce the risk for CMD. Yet, dietary recommendations to include LA as part of a lifestyle plan with the goal of preventing CMD remain elusive.
Recent findings
Clinical interventions consistently show that dietary the addition of LA to the diet improves body composition, dyslipidemia, and insulin sensitivity while reducing systemic inflammation and fatty liver. These effects of LA position dietary LA-rich oils as a potential dietary strategy to aid in preventing CMD. Peroxisome proliferator-activated receptors (PPARs) are nuclear hormone receptors that are cellular targets for many polyunsaturated fatty acids and oxylipin metabolites. PPAR activation can regulate dyslipidemia, insulin sensitivity, adipose biology, and inflammation, potentially explaining the plethora of effects of dietary LA on aspects of CMD.
Summary
Unraveling the cellular mechanism(s) of LA to impact PPAR activity may reset a false dogma that LA, as a member of the omega-6 fatty acid family, promotes inflammation in humans. In fact, LA appears to reduce inflammation and reduce risk for CMD.
