Omega-6 & Heart Health: Benefits of Linoleic Acid
Discover how the omega-6 fatty acid linoleic acid could be a game-changer for your heart health.New research presented at the annual NUTRITION meeting reveals a potential link: higher levels of linoleic acid in the blood are associated with reduced risks of type 2 diabetes and cardiovascular disease (CVD). This essential nutrient, found in seed oils, might lower inflammation.The study, which used objective biomarkers, showed a correlation between linoleic acid and decreased cardiometabolic risk factors, including those associated with inflammation. The data suggests that those with elevated levels of linoleic acid had a healthier risk profile overall.

Omega-6 Fatty Acid Linked to Lower Diabetes,CVD Risk
Updated June 10,2025
ORLANDO — Presenting at the annual NUTRITION meeting,researchers suggested that linoleic acid,an omega-6 fatty acid abundant in seed oils,may play a role in reducing the risk of type 2 diabetes and cardiovascular disease (CVD).
Kevin C. Maki, adjunct professor at the Indiana University School of Public Health-Bloomington, and his team noted prior research indicating a potential link between omega-6 polyunsaturated fatty acids and lower type 2 diabetes risk. Linoleic acid, primarily sourced from plant foods and vegetable oils like corn and soybean, is a key omega-6 fatty acid.
Maki said there is increasing concern that seed oils promote inflammation and raise cardiometabolic risk.
The researchers conducted a cross-sectional analysis of nearly 1,900 individuals, assessing the relationship between omega-6, serum linoleic acid, BMI, and glucose homeostasis biomarkers.Their findings indicated that higher levels of linoleic acid in blood plasma correlated with reduced levels of cardiometabolic risk biomarkers, including those associated with inflammation.
Maki said their study used objective biomarkers rather than diet records to assess linoleic acid intake and measured a range of markers of inflammation and indicators of glucose metabolism.
The study consistently linked higher linoleic acid levels with lower levels of risk factors for type 2 diabetes and CVD, such as insulin and glucose. Biomarkers for inflammation, including serum amyloid A, glycoprotein acetyls, and C-reactive protein, were also lower.
Maki said people with higher levels of linoleic acid in their blood tended to have a healthier overall risk profile for heart disease and diabetes.
The researchers believe these results underscore the need for further studies to determine if increased linoleic acid intake can improve cardiometabolic risk factors and reduce the incidence of stroke, type 2 diabetes, and heart attacks.They plan to investigate the impact of different oils with varying fatty acid levels on cardiometabolic risk factors.
What’s next
Future research will explore how different oils with varying fatty acid profiles affect cardiometabolic health, potentially leading to dietary recommendations for reducing the risk of heart disease and diabetes.
