The debate around seed oils is nuanced. Cleveland Clinic notes that seed oils' high omega-6 content "can lead to inflammation" when consumed excessively and imbalanced with omega-3s. However, Stanford and University of Queensland researchers caution that the full picture is more complex. Some studies show linoleic acid (the omega-6 in seed oils) doesn't consistently raise inflammation markers in controlled settings.
From a personal sensitivity standpoint: for people with pre-existing gut inflammation, gluten sensitivity, or IBD, reducing inflammatory inputs, including highly processed oils, often yields noticeable improvement. My own experience aligns with this. This guide reflects that lived experience, not a blanket anti-seed-oil ideology.
