Blood Fatty Acid Patterns Linked to Cardiovascular-Kidney-Metabolic Health Stage

This study looked at fatty acids stored in red blood cells (a marker of longer-term dietary fat intake) in over 5,000 U.S. adults, and examined how different patterns of these fatty acids related to “cardiovascular-kidney-metabolic” (CKM) syndrome staging — a framework that combines heart, kidney, and metabolic health into one overall risk score.

Researchers identified three main fatty acid patterns using statistical modeling. One pattern, reflecting higher omega-3 fatty acid levels, was linked to lower odds of being in a more advanced CKM stage. Another pattern, related to certain fatty acid conversion processes (involving enzymes that build monounsaturated fats), was linked to higher odds of more advanced CKM stage. A third pattern, contrasting saturated/monounsaturated fats with polyunsaturated fats, showed no clear or consistent relationship.

These associations held up after adjusting for other factors, and were generally consistent across different age groups and between men and women.
