Even when people ate a very high amount of trans fats—either artificial or from dairy—their blood proteins didn’t change enough to be picked up by the method used, meaning this way of studying proteins might not be good for spotting diet effects.

A high intake of industrial or ruminant trans fatty acids does not affect the plasma proteome in healthy men

Scientists gave men diets high in certain unhealthy fats and checked if their blood proteins changed— they didn’t, meaning this method of analyzing blood proteins can’t detect small diet effects.

Similar Assertions

Even when people ate a lot of artificial trans fats—way more than normal—their blood proteins didn’t change much, so these fats might not mess with the body’s protein signals in a big way.

Even when people ate a lot of a specific trans fat found in dairy (CLA), their blood proteins stayed pretty much the same, so this type of fat probably doesn’t change how the body uses proteins in the blood.
