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.
Scientific Claim
An extreme dietary intervention providing 7% of energy as trans fats or CLA does not markedly affect the plasma proteome in healthy men, suggesting that plasma proteomics via 2-DE may be insufficient for detecting dietary-induced protein changes.
Original Statement
“the nature of an extreme dietary intervention, i.e. 7% of energy provided by industrial trans fat or cis9,trans11 CLA, did not markedly affect the plasma proteome. Thus plasma proteomics using 2-DE appears, by and large, an unsuitable approach to detect regulation of plasma proteins due to changes in the diet.”

Assessment Explanation
The abstract uses 'appears... unsuitable'—a probabilistic, cautious phrasing consistent with the study’s design and sample size. The claim is appropriately limited to the method’s performance, not generalizability.
Evidence from Studies
Supporting (1)
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.
