This message brought to you by seed oil manufacturers.
I tried it myself, dropped seed oils in favor of butter and feel 20 years younger. Turned the food pyramid upside down. Went from a visit to the doctor every couple of months to a visit every few years.
I found that I can’t digest the hydrogenated stuff very well. Never could, but it really becomes apparent as we get older. Just tears up my gut and downstream. Inflammation is what they call it.

It looks more like the large industrial food product manufacturers have “regulatory capture”, and drive the “science”. You get the studies you pay for, and they paid for “seed oils are healthy”.
