The debate surrounding seed oils has gained significant traction in recent years, evolving from niche internet discussions to a highly politicized movement. Online conversations about the health impacts of seed oils began approximately seven to eight years ago, sparking widespread intrigue and controversy. In 2017, Chris Knobbe, an ophthalmologist, added fuel to the fire by publishing a paper that linked vegetable oils, particularly seed oils, to macular degeneration. Meanwhile, Sweetgreen, a well-known salad chain, has responded to mounting pressure by eliminating sesame and sunflower seed oils from its cooking practices, opting for avocado and olive oil instead.
Influencers and public figures have significantly impacted the anti-seed oil movement. Joe Rogan and Paul Saladino have emerged as influential voices, using their platforms to challenge the health benefits of seed oils. Joe Rogan has famously stated, "Your body doesn't know what the fuck to do with canola oil," and "Not only is it terrible for you, there's evidence that it makes you hungrier." Paul Saladino echoes these sentiments, asserting, "there's a direct correlation between incorporating these processed seed oils and terrible health results." Robert F. Kennedy Jr. has also joined the fray, declaring that Americans have been "unknowingly poisoned" by these oils.
Despite the growing momentum against seed oils, leading health organizations maintain their stance on their nutritional value. The FDA, American Heart Association, and most medical associations continue to assert that seed oils are not only safe but healthier than solid animal fats. This message is bolstered by experts like Eric Decker, a professor of food science, who emphasizes the benefits of omega-3 fatty acids found in certain oils. Decker notes, "I would always say to people, 'You know, you should eat an omega.'"
The anti-seed oil movement's rise can be attributed to a combination of misinformation and misconceptions about their health effects. Experts such as Eric Decker and Dariush Mozaffarian argue that current scientific evidence does not support claims that seed oils are the primary cause of diseases like obesity and macular degeneration. Mozaffarian highlights the benefits of omega-3 fatty acids and omega-6 fatty acids, stating they are "both good for us. We need more of them, and we're underconsuming both of them."
The manufacturing process of seed oils, which often involves bleaching, deodorizing, and adding chemicals, has also become a focal point for critics. Some argue that these processes strip the oils of their nutritional value and introduce harmful substances into the diet. However, experts caution against sensationalist narratives that lack scientific backing.
The anti-seed oil movement has transcended health discussions and entered the political arena. Politicians like JD Vance have voiced support for the cause, further polarizing the debate. Apps and websites such as Seed Oil Scout have emerged to inform consumers about which restaurants have ceased using seed oils.
Jonathan Neman, co-founder of Sweetgreen, acknowledges the broader implications of this debate, stating, "Our country is having a long-overdue conversation about food." Meanwhile, Robert F. Kennedy Jr. quips, "It's time to Make Frying Oil Tallow Again," underscoring the movement's push towards alternative cooking fats.
