The Study
Dietary fatty acids affect plasma markers of inflammation in healthy men fed controlled diets: a randomized crossover study.
This is a high-quality experiment where men were randomly assigned to different diets, which is the gold standard for testing cause-and-effect. Because of the random assignment, we can reasonably say the diet changes likely caused the inflammation marker changes they observed. However, since we only have the abstract, we're missing some details about how well the study was done.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Researchers fed 50 healthy men different diets with specific fats for 5 weeks and measured how these fats affected markers of inflammation in their blood.
