Are Seed Oils Unhealthy? RFK Jr Calls Them 'Toxic' But Experts Say Evidence Shows Benefits

Seed oils have become a lightning rod in online health debates, with US health secretary Robert F Kennedy Jr labeling them 'toxic' and vowing action. Influencers claim they cause inflammation and disease, but Australian experts push back. Prof Lauren Ball of the University of Queensland says there's no convincing evidence that normal amounts of canola or sunflower oil harm health, noting they contain beneficial unsaturated fats. Dr Jason Wu of UNSW adds that evidence consistently points to health benefits from seed oils. Randomized trials show omega-6 fatty acids in these oils do not increase inflammation. While dietary guidelines advise limiting them due to calorie density, they do not recommend avoidance. The controversy highlights a gap between social media fearmongering and scientific consensus. As the debate rages, consumers are left to weigh influencer claims against expert guidance. The takeaway: enjoy seed oils in moderation as part of a balanced diet.
