The Establishment Is Pushing Back on Seed Oils. Here's Why That's Actually a Good Sign.
Something interesting happened this week in the world of nutrition science.
STAT News published a piece on May 22nd titled "What the anti-seed oil movement gets wrong, and right." A new review in Critical Reviews in Food Science and Nutrition declared that the "totality of evidence" supports seed oil safety. The coverage was coordinated and the message was clear: the people worried about seed oils are confused, misinformed, and probably too online.
If you've been following the MAHA movement, ancestral health, or functional medicine for any length of time, you recognized the playbook immediately. When the establishment publishes a round of myth-busting pieces all at once, it usually means something is threatening the myth.
Here's what they're not telling you.
The dietary guidelines just validated the anti-seed oil crowd
This one got buried, but it matters. The 2026 dietary guidelines, released earlier this year, listed butter and beef tallow alongside olive oil as acceptable cooking fats. That is not a small thing. For 60 years, the official guidance has treated saturated fat as public enemy number one. Quietly revising that while simultaneously running a media campaign defending seed oils is a contradiction worth noting.
The food industry is already moving on
Steak 'n Shake, PepsiCo, Kraft Heinz, General Mills, and Nestle have all announced plans to remove or reduce seed oils from their products. These are not small, wellness-adjacent brands. These are the largest food companies on earth. They do not make expensive supply chain changes because of social media trends. They make them because consumer demand has shifted and they can see where this is heading.
The scientists defending seed oils and the food companies quietly removing them are not operating in the same reality.
What the "myth-busting" research actually says
The studies being cited this week are mostly observational, meaning they track what people eat and correlate it with health outcomes over time. They are not randomized controlled trials. The two most rigorous RCTs ever conducted on this question, the Sydney Diet Heart Study and the Minnesota Coronary Experiment, both found higher mortality in the groups that replaced saturated fat with seed oils. The Minnesota study sat unpublished for 16 years. The lead researcher's own son helped recover and publish the data in the BMJ in 2016.
The observational studies also share a consistent flaw. The "low seed oil" comparison group is rarely someone eating grass-fed meat and olive oil. It is usually someone eating more processed food made with other fats. That is not a meaningful comparison, and the researchers know it.
The oxidation problem nobody wants to talk about
Seed oils are polyunsaturated fats with high linoleic acid content. Unlike saturated fats, they oxidize rapidly under heat. When you cook with canola or soybean oil at high temperatures, you generate aldehydes and oxidized lipids. These are not theoretical concerns. They are measurable compounds with documented links to cellular damage. The studies measuring linoleic acid in the bloodstream are not measuring what those fats look like after they have been heated to 375 degrees in a commercial fryer.
This is not in the STAT News piece.
The bottom line
You do not need to wait for official guidance to catch up. Here is what the actual evidence supports:
Cook with stable fats. Butter, ghee, tallow, coconut oil, and extra-virgin olive oil for lower heat have been part of human diets for thousands of years and do not break down the same way under heat.
Read ingredients. Soybean oil, canola oil, sunflower oil, and "vegetable oil" appear in nearly every packaged food product. Minimizing ultra-processed food largely solves the seed oil problem on its own.
Ignore the dietary fat panic. The case against saturated fat has been eroding for two decades. The establishment is slow to move because admitting the error means acknowledging 60 years of bad guidance.
The companies are already ahead of the science on this one.

Quick Hits
FDA launches reassessment of BHT and ADA. On May 12, the FDA finalized its Food Chemical Safety Post-Market Assessment Program and immediately kicked off a review of BHT (a common preservative) and azodicarbonamide (ADA, the "yoga mat chemical" used in commercial bread). Both have been in the food supply for decades despite limited long-term safety data. This is a direct result of MAHA pressure on the agency. Worth watching.
MAHA kills Big Food's preemption bill. A legislative effort backed by major food industry groups that would have blocked states from passing their own food additive laws was killed this month following significant MAHA-aligned pushback. Eighteen states have already received SNAP waivers to restrict junk food purchases, and the food lobby was trying to stop states from going further. It did not work.
Whole milk is back in schools. The USDA finalized new regulations allowing schools to serve whole milk across all federal nutrition programs starting this month. Low-fat milk has been the only option in school cafeterias since 2012. The science on whole milk and childhood health has never actually supported that restriction. Better late than never.
