The latest “health” craze is all about condemning “seed oils”. I’m a guy with a family history of heart disease, so I pay attention to doctors’ dietary recommendations, and I never heard anything about “seed oils” until recently, and the complaints were always coming out of the mouths of fools.

Robert F. Kennedy Jr., the new health secretary, has said Americans are being “unknowingly poisoned” by seed oils and has called for fast-food restaurants to return to using beef tallow, or rendered animal fat, in their fryers instead.

Recommendations from RFK jr tend to make me run in the opposite direction, but apparently there are a lot of gullible Americans who readily adopt any claim made by an anti-scientist. And then every corporation stampedes to follow the money.

In response to consumer concerns, some food-makers have stripped seed oils from their products. Restaurants like the salad chain Sweetgreen have removed them from their menus. Many Americans say they now avoid seed oils, according to a recent survey from the International Food Information Council, an industry trade group.

The seed oil discussion has exasperated nutrition scientists, who say decades of research confirms the health benefits of consuming such oils, especially in place of alternatives such as butter or lard.

“I don’t know where it came from that seed oils are bad,” said Martha Belury, an Ohio State University food science professor.

I know! I know! It comes from wellness influencers. All you need is a tiktok channel and a lot of unfounded confidence, and you too can promote weird random ideas under the guise of making people “well”. You don’t need a medical degree! You don’t even need to be a college graduate! Wellness isn’t a real scientific/medical discipline — it’s just a buzzword that has no regulatory oversight or any basis in empirical data. We all want to be well, but to have any authority in medicine requires years of training and constant updating from real sources.

I found something called Your Ultimate Guide to Becoming a Successful Health and Wellness Influencer. It’s revealing. The way to become a wellness influencer is a) find something you’re passionate about, b) connect with a community of wellness influencers, and c) land a brand deal. That last one is obviously the most important. Nowhere does it say you should study medicine or nutrition, or read scientific studies, or even be capable of understanding scientific studies. Just promote whatever random bias is floating around in your head!

It also helps to be young and slender and capable of doing yoga poses. Here’s a whole page of wellness photos you can use to build a page promoting your brand. Take a look and let me know if there’s anything illustrating knowledge or expertise; there is a common theme, and that’s not it.

In that article dismissing the seed oil obsession, you instead find studies and numbers.

Belury, who has studied fatty acids for three decades, says that claim is based on an oversimplification and misunderstanding of the science. Studies have shown that increased intake of linoleic acid, the most common omega-6, does not significantly affect concentrations of inflammatory markers in the blood, she said.

“Scientists who study omega-6 and omega-3 think we need both,” Belury said. “Seed oils do not increase acute or chronic inflammation markers.”

In addition, research from the American Heart Association and others has consistently shown that plant-based oils reduce so-called bad cholesterol, lowering the risk of heart disease and stroke, especially compared with sources high in saturated fat.

That’s found in new research from Brigham and Women’s Hospital scientists as well. A study of more than 200,000 adults over more than 30 years released Thursday found that people who ate the highest amounts of butter had a 15% higher risk of dying than those who ate the least. People who ate the most plant-based oils — including seed oils — had a 16% lower risk than those who ate the least.

Dr. Daniel Wang, who led the research, said new modeling data suggests that swapping less than a tablespoon a day of butter for equal calories of plant-based oils could lower premature deaths from cancer and overall mortality by 17%. Such a small daily change could result in “a substantial benefit,” Wang said.

Gosh. Belury and Wang are never going to be rich, famous, and popular at that rate. Americans don’t want to be told about data, they want to see a glossy image of sexy people sipping a drink with an umbrella in it while sitting on a beach in Costa Rica. That’s wellness, not a bunch of studies showing what’s actually effective in reducing mortality.

I think I’ll just listen to boring doctors in Minnesota who tell me to eat less red meat and consume more olive oil and salmon. It seems to be working; most of my ancestors seem to have died in their 50s, and I’ve made it to almost 70, and I haven’t made any major sacrifices in my lifestyle. A Mediterranean diet is delicious and good for you.

Unfortunately, I don’t look like a 20-something model and I don’t have a wellness supplement to sell.
