Controlling Fat Chemistry: Trans Fats, Cooking Stability, and Industrial Loopholes

Understand the precise chemical reasons why heating common cooking oils creates dangerous trans fats, allowing you to stabilize your dietary fats from the kitchen to industrial processes.

Short Summary

  • You create trans fats at home when high heat flips the cis bond in unsaturated oils into a trans shape.
  • Saturated fats (like animal fat or MCTs) are heat-stable because they lack double bonds needed for flipping.
  • Food manufacturers create unlabeled trans fats using high-heat extruders, bypassing mandated ingredient disclosure.

Dr. Robert Lustig breaks down the biochemistry of cooking fats to explain why the industry’s blanket categorization of "a fat is a fat" is dangerous. This discussion reveals which oils degrade under heat, the risks posed by common seed oils, and how food processing hides harmful additives.

The fact that trans fats formed during processing don't have to be listed on labels is a huge loophole. It feels deceptive that consumers can't easily tell what's in their food. 🤔

Baking with oil is just as bad as frying. Think of all the baked foods we cook in the oven.

Also I've recently swapped to beef tallow for cooking and coconut oil for baking.

Read "Dark Calories" by C. Shanahan and you'll get to know what are seed oils and to what extent they are deleterious to our health.

The Italian Government food administration have found the Pure virgin olive oil is rare today as crime groups have mixed low grade olive oil with expensive olive oil so can charge top price and these adulterated oils are big business and has been have known about this fact for years. Labeling is fraught with inaccuracies.

I know this is an old interview but Dr lustig should know that peanut oil and sesame seed oil have high linoleic acid. There are some ligurian olive oils that have very low linoleic acid.

Overall we need to reduce fried foods... Or totally eliminate them.... Whichever fat you're using.
