human Lipidome Study Reveals New Health indicators
Updated June 28, 2025
Scientists are increasingly focused on the lipidome, the complete set of lipids in the body, to better understand human health.Lipids, including fats, oils, cholesterol, hormones and some vitamins, play crucial roles in cell structure, energy storage, and immune response.
Unlike the relatively stable genome, the lipidome is highly responsive to diet and gut microbes, making it a potential target for health interventions. However, the sheer variety of lipid molecules has posed a challenge to researchers.
Michael Snyder, professor of genetics at Stanford University, noted the understudied nature of lipids. “They are involved in pretty much everything,” Snyder said, adding that their heterogeneity makes understanding their functions difficult.
A study from Snyder’s lab, published in Nature Metabolism, investigated the human lipidome and its changes in both healthy and diseased states, notably in Type 2 diabetes development. the research highlights the importance of the lipidome in understanding overall health and disease progression.
The study tracked over 100 participants,including those at risk for diabetes,for up to nine years. Participants provided blood samples regularly, allowing researchers to monitor changes in their lipid profiles.
Using mass spectrometry, the team cataloged approximately 800 lipids and their associations with conditions such as insulin resistance, viral infections, and aging.The study revealed that while each person has a unique and stable lipidome signature, specific lipids change predictably with health status.
More than half of the cataloged lipids were linked to insulin resistance, a precursor to Type 2 diabetes.Understanding these lipid changes can provide insights into the biological mechanisms at play,even though insulin resistance is typically diagnosed via blood glucose measurements.
Daniel Hornburg, former post-doctoral scholar in Snyder’s lab, said that identifying disease-associated molecules offers potential targets for affecting disease progression.
Researchers also identified over 200 lipids that fluctuate during respiratory viral infections. These fluctuations correlate with energy metabolism and inflammation, potentially indicating disease trajectory.Participants with insulin resistance showed atypical responses to infection and weaker responses to vaccinations.
The study’s wide age range (20-79 years) and duration allowed researchers to observe lipidome changes with aging. Most lipids,like cholesterol,increase with age,while others,such as omega-3 fatty acids,decrease. The rate of these changes varies, with insulin resistance appearing to accelerate them.
Si Wu, another former postdoc in snyder’s lab, suggested that lipid profiles might predict an individual’s biological aging rate.
Wu also noted that certain lipid groups, like ether-linked phosphatidylethanolamines, consistently correlated with better health, suggesting their potential as health monitoring tools or dietary supplements.
