Extensive human clinical research shows that seed oils, which are high in linoleic acid and omega-6 fatty acids, do not cause increased inflammation. Systematic reviews of randomized controlled trials, such as those cited by the Academy of Nutrition and Dietetics and published in PubMed, consistently find no effect or a neutral effect on inflammatory markers when people consume seed oils.
Harvard T.H. Chan School of Public Health and Stanford Medicine both affirm that the widespread belief that seed oils are pro-inflammatory is not supported by human evidence. Epidemiological studies even associate higher polyunsaturated fat intake with better cardiometabolic outcomes, not greater inflammation.
The claim that omega-6 fatty acids from seed oils inherently trigger body-wide inflammation stems from a misunderstanding of biochemical pathways and is not reflected in randomized controlled trials or systematic reviews. Major health organizations recommend unsaturated fats, like those in seed oils, as part of a healthy diet.
