When you take the oil out of the avocado, you lose the stuff that protects it, so it goes bad faster when you cook with it.
Scientific Claim
Isolation of lipids from whole foods removes endogenous antioxidants and structural matrices, increasing susceptibility to oxidative degradation under thermal stress.
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.”

When fats are put back into fish gel using a special protective shell, they don't break down as easily when frozen and thawed — proving that keeping fats inside a natural structure helps protect them.
Technical explanation
This paper directly compares lipid stability in surimi gels with and without structural stabilization (HIPPEs), showing that intact structural matrices (emulsion-based) reduce lipid oxidation under thermal/freeze-thaw stress — directly supporting the assertion that isolation without structural matrices increases susceptibility.
When scientists take fat out of milk to make baby formula, it goes bad faster — but they can slow it down by adding special protective layers, proving that natural structures in whole foods keep fats from spoiling.
Technical explanation
This study explicitly tests how structural factors — droplet size, interfacial composition, and emulsifiers — affect lipid oxidation under accelerated thermal storage, directly demonstrating that removing lipids from their natural matrix (e.g., in milk) increases oxidation unless artificially stabilized.
Contradicting (2)
They took antioxidants out of seeds and still used them to stop fat from going bad — meaning isolation doesn't always remove protection.
Technical explanation
This paper isolates antioxidants from seeds and shows they can still protect lipids — suggesting that even after isolation, endogenous antioxidants retain function, contradicting the assertion that isolation removes protective capacity.
Even after processing cheese, adding good bacteria made it more stable and antioxidant-rich — so isolation doesn't always mean losing protection.
Technical explanation
This study shows that processing dairy (a form of isolation) with probiotics enhances antioxidant potential and stability — implying that isolation doesn't necessarily remove protective capacity if supplemented.
