Mindsip insights from this episode:
Beware hidden dangers of rice bran oil contamination
Historical mass poisonings have occurred from rice bran oil contaminated with PCBs, and modern brands can still contain traceable heavy metals.
Beware of hidden oils in restaurant olive oil
Even when restaurants claim to cook with olive oil, it is often secretly cut with up to 25% cheaper oils like canola.
Avoid grapeseed oil due to carcinogenic risks
Grapeseed oil, a waste product from winemaking, can contain high levels of PAHs, which are carcinogens known to mutate DNA.
Recognize canola oil's role in tire flexibility and food products
Canola oil is used as a plasticizer to make car tires more flexible, yet it is also a common ingredient in foods like coffee creamers.
Avoid seed oils due to toxic processing with hexane
Seed oils are soaked in hexane, a crude oil derivative, and the US FDA does not regulate its residue in the final product, unlike regulations in Europe.
Investigate Crisco's rise due to AHA's endorsement after Procter & Gamble donation
The American Heart Association promoted Crisco over traditional fats after receiving a donation from Procter & Gamble worth $20 million in today's money.
Avoid deodorized seed oils to prevent toxic inflammation
The final high-heat deodorization step is the most damaging part of seed oil processing, as it oxidizes unstable fats and creates inflammatory toxins called aldehydes.
Avoid unrefined cottonseed oil to prevent liver damage
Unrefined cottonseed oil contains a toxic compound called Gossipol, which can cause liver damage and immune suppression.
