Growing up, I used to think the beans my aunt made with vegetable oil tasted better than my mum's palm oil version. And until recently, I actually believed "vegetable oil" meant something cold-pressed, clean, and closer to nature.
It does not.
Here is what your bottle of "vegetable oil" likely is: crude palm oil that has been degummed, neutralised, bleached, and deodorised until it is colourless, odourless, and completely stripped of the nutrients it started with.
So why are we choosing this over traditional red palm oil in the first place?
Crude palm oil is naturally rich in beta-carotene (that deep orange-red colour). That colour, and everything it represents nutritionally, has to be removed for the oil to look "clean" and have a long shelf life.
To do this, manufacturers run the oil through acid-activated clays (treated with sulphuric or hydrochloric acid) under high heat and vacuum. Then deodorisation by heating the oil above 200Β°C to strip away taste and smell.
But what you should know is: This high-temperature refining leaves behind:
β 3-MCPD esters: classified as possibly carcinogenic (IARC Group 2B).
β Glycidyl esters: when digested, these break down into glycidol β a substance the European Food Safety Authority (EFSA) has confirmed is both genotoxic and carcinogenic.
These are not added ingredients. They are created by the refining process itself.
Meanwhile, unrefined red palm oil β the one we pushed aside for looking "too local" β never goes through this process. Its beta-carotene, vitamin E, and natural fatty acid profile remain intact.
I am not saying palm oil is perfect. I am saying we need to ask harder questions about what we replaced it with and why.
What oil are you cooking with?
