How Omega-3 and Omega-6 Fats May Influence Which Genes Get Switched On
This scientific review looks at how dietary fats, specifically omega-6 and omega-3 fatty acids, can influence the activity of genes involved in important body processes like fat production, sugar metabolism, glucose transport, and inflammation.
The authors explain that some of these effects happen through hormone-like compounds called eicosanoids that are made from these fats. However, they also found that fatty acids can turn down genes related to fat-building and sugar-burning pathways through a separate mechanism that works directly inside the cell nucleus, without needing eicosanoids at all.
This suggests that the fats we eat may act almost like chemical messengers, directly interacting with the machinery that controls gene activity, rather than only working through traditional hormone-like signaling.
What this means for you
This is a science-focused review, not a clinical trial, so it doesn’t tell us about specific health outcomes in people. Instead, it helps explain one of the biological reasons why the type of fat in our diet, including omega-3s, may matter at a cellular level, laying groundwork for future research into nutrition and metabolic health.
