Eating more omega-3 fats — like those in fish and certain oils — is linked to fewer inflammation-causing cells in belly fat.
Scientific Claim
Increased consumption of n-3 fatty acids, particularly α-linolenic acid and EPA, is associated with a lower proportion of proinflammatory macrophages in human visceral adipose tissue.
Original Statement
“The proportion of PIMs correlated negatively with content of both α-linoleate and eicosopentaenate (EPA). A significant inverse correlation of all n-3 FAs to α-linolenic acid was likewise documented... a very significant inverse correlation between the proportion of PIMs and the n-3/n-6 fatty acid ratio was found.”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The data show correlation, not causation. The study did not control diet or assign interventions, so 'associated with' is the only appropriate verb.

Rapid Drop in Coronary Heart Disease Mortality in Czech Male Population—What Was Actually behind It?
When people ate less animal fat and more healthy fats like those in fish and plants, their body’s inflammatory cells in fat tissue decreased—meaning less inflammation, which is good for the heart.
