Social Media Hates Seed Oils—but Scientists Say They’re Not So Bad

New research presented at the American Society for Nutrition’s Nutrition 2025 conference suggests that seed oils, often demonized on social media, may actually be beneficial for cardiometabolic health. The study found that higher levels of linoleic acid, a type of omega-6 fatty acid found in seed oils, were associated with lower levels of inflammation and insulin resistance in nearly 1,900 people. This contradicts the common claim that seed oils are harmful to health, instead highlighting their potential benefits.

Another study presented at the conference emphasized the importance of overall food quality for long-term health. Researchers found that eating high-quality, nutrient-dense whole plant foods was associated with better health outcomes, regardless of whether individuals followed a low-fat or low-carb diet. The findings challenge misconceptions circulating on social media, such as the belief that butter is a healthy fat, and suggest that opting for plant-based oils over animal-based ones can significantly reduce the risk of mortality and cancer-related deaths.
