Why your cookies don't have bad fats anymore
Assessment of the Presence of Partially Hydrogenated Oils (PHOs) as a Source of Industrially Produced Trans Fatty Acids (i-TFAs) in Packaged Foods in Poland, Pre- and Post-Implementation of EU Regulation 2019/649

A new law made food companies stop using a harmful fat called PHOs in snacks and baked goods. But many replaced it with palm oil, which has lots of saturated fat — not great either.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

The oil that replaced the bad trans fat (palm oil) is mostly saturated fat — which is also bad for your heart — so swapping one bad fat for another might not help much.
Industrial hydrogenation of vegetable oils generates trans fatty acids, which are causally linked to increased risk of cardiovascular disease and metabolic dysfunction.
About 4 in 10 of the foods that used to have the bad oil were just taken off the shelves entirely instead of being changed to use a different fat.
When companies stopped using the bad oil (PHOs), more than half of them switched to palm oil — which is high in saturated fat, another type of fat linked to heart disease.
After the law changed, not a single packaged food product in Poland had the harmful oil called partially hydrogenated oil on its label anymore.
