A new study reveals genetic influence on omega-3 metabolism in Hispanic Americans.
Omega-3 fatty acids are essential in human health, influencing multiple organ systems and physiological responses. However, a person’s omega-3 status varies depending on several factors, including their genetic makeup. A new study shows that genetic differences influence how Hispanic Americans metabolize omega-3s.
Researchers conducted a genome-wide association study, a type of observational study that searches the genome for minor variations in people’s DNA within a particular population. Their analysis included more than 1,400 Hispanic Americans and more than 2,200 African Americans.

They found that the two groups shared many genetic similarities regarding omega-3 metabolism with European Americans. However, they also identified distinct differences, some influencing how Hispanic Americans metabolize omega-3s. Most of these differences occurred in the FADS region on chromosome 11. FADS (fatty acid desaturase) is a gene that encodes a family of enzymes that convert saturated fatty acids into unsaturated and polyunsaturated fatty acids.
These findings provide a better understanding of the genetics underlying omega-3 fatty acid metabolism in diverse genetic groups and underscore the importance of considering ancestry in genetic studies.
