Seed oils get a lot of attention when people talk about ultra-processed foods, but the conversation is often missing an important piece.
The presence of a seed oil doesn’t tell you the whole story.
Take a bag of chips. It’s not simply potatoes + seed oil. Ultra-processed foods can contain a combination of refined starches, added fats, sodium, flavorings, and ingredients that make them highly palatable.
So when we see associations between diets high in seed oils and poorer health outcomes, an important question is:
Is the association related to the seed oil itself, or to the larger dietary pattern and higher intake of ultra-processed foods?
Those are not the same thing.
There’s a lot more nuance to this conversation than we can fit into one graphic.
