New Study Explore How Peanuts Affect Lipid Circulation In The Blood

 

A new study by researchers from the German Institute of Human Nutrition (DIfE) and international partners has identified a distinct "Peanut Lipidomic Signature" (PeLS) in the blood following regular peanut consumption.

Very Long-Chain Saturated Fatty Acids (VLCSFAs): Eating peanuts significantly increases circulating levels of VLCSFAs, specifically C24:0 (tetracosanoic acid) and C22:0 (behenic acid).

·         Lipid Remodeling: These fatty acids do not just raise overall fat levels; they are actively and preferentially incorporated into specific lipid classes—

such as ceramides—through the coordinated work of chain-elongating enzymes.

·         Metabolic Impact: Using high-resolution mass spectrometry ("deep lipidomics"), the research demonstrates that peanuts trigger a complex metabolic remodeling of the blood lipidome rather than a simple caloric contribution.

 

Broader Cardiovascular Context: Complementary data from intervention and cohort studies (such as the ARISTOTLE study and the EPIC-Potsdam Study) link this peanut-induced lipid profile to a lower risk of cardiovascular disease (CVD) and type 2 diabetes (T2D). Previous trials also note reductions in blood triglycerides and improved total-to-HDL cholesterol ratios. [1, 2, 3, 4]
