Taking fat out of whole food makes it break down faster and become harmful when cooked.
Scientific Claim
Isolation of lipids from their native food matrix removes endogenous antioxidants and structural protections, increasing susceptibility to oxidative degradation during thermal exposure.
Original Statement
“When you extract oil from any food, you concentrate certain compounds and remove the protective matrix that whole food provides. Whole avocados contain fiber, water, and various compounds that slow down absorption and oxidization. But when you strip all of this away, and all you have left is the oil, it becomes very vulnerable to damage, especially under heat.”

Even when the body has lots of natural antioxidants, taking fats out of their original cell structure makes them more likely to break down when heated or exposed to air—because the cell’s built-in protection is gone.
Cassava starch films with nanoencapsulated carvacrol inhibit bacterial growth and reduce lipid oxidation in ground beef.
When meat is wrapped in a special film with natural antioxidants, it doesn't go bad as fast — this suggests that without these protective substances, fats in meat break down more easily when exposed to air or heat.
Isolation of antioxidative peptide from the protein hydrolysate of <i>Caragana ambigua</i> seeds and its mechanism for retarding lipid auto‐oxidation
When lipids are taken out of their natural food source, they lose natural protective chemicals that keep them from going bad when heated. This study shows that adding a special peptide back in helps prevent that damage, meaning those protections were missing after isolation.
A Simple and Rapid Purification Procedure Minimizes Spontaneous Oxidative Modifications of Low Density Lipoprotein and Lipoprotein (a)
When scientists take fats out of their natural environment in the body, they lose protective stuff like vitamins that keep them from going bad—this study shows those fats spoil faster when taken out, but if you handle them quickly and gently, they stay healthier.
