Genetic Research Reveals Role of Omega-3, Omega-6 Fatty Acids
Updated June 27, 2025
New research from the University of Virginia School of Medicine sheds light on how genes effect the way African-Americans and Hispanic-Americans utilize Omega-3 fatty acids and Omega-6 fatty acids. The findings represent progress toward “precision nutrition,” where customized diets optimize health.
Omega-3 and Omega-6 fatty acids, considered ”healthy fats,” can be obtained through diet or supplements. Omega-3 supports the immune system and may reduce heart disease risk, while Omega-6 promotes immune health. Both play crucial roles in cell function. Higher levels of these fatty acids in the bloodstream are linked to a lower risk of heart disease, Type 2 diabetes, Alzheimer’s, and certain cancers.
While previous research has explored the genetic influence on Omega-3 and Omega-6 use in people of European descent, less is known about these processes in Hispanic and African Americans. Ani W. Manichaikul, PhD, and her team at UVA aimed to address this gap. Their results show both similarities and key differences, underscoring the need for diverse genetic studies.
“People of diverse ancestries have some distinct features in their DNA, and we can find this genetic variation if we include diverse participants in research,” said Manichaikul, of UVA’s Center for Public Health genomics and Department of Public health Sciences. “The results from this study bring us a step closer to considering a full spectrum of genetic variation to predict which individuals are at increased risk of fatty acid deficiencies.”
To investigate genetic differences, researchers analyzed data from over 1,400 Hispanic-Americans and 2,200 African-Americans, gathered through the CHARGE consortium. The Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium facilitates large-scale genetic analyses.
the team found that prior genetic findings in people of european ancestry ofen held true for Hispanic and African-descended people. For instance, a specific chromosomal location known to regulate fatty acid use in Europeans also proved important in the other groups. However,they also identified previously unknown genetic sources of variation in fatty acid levels among both Hispanic-Americans and African-Americans.
These newly detected differences help explain variations in how these groups process fatty acids. They may also provide insights into why Hispanic people with notable American Indigenous ancestry often have lower fatty acid levels in their blood.
The researchers published their findings in communications Biology. The research was supported by the National Institutes of health and the Daniel B. Burke endowed Chair for Diabetes Research. Manichaikul’s team included Chaojie Yang,Jenna Veenstra,and others. the researchers report no financial conflicts of interest.
What’s next
The findings pave the way for future research into how fatty acid differences impact diseases like cancer and immune system function. This could lead to “precision nutrition” strategies, using tailored diets or supplements to improve health outcomes.
