Hispanic people with a high percentage of American Indigenous ancestry are at increased risk of an omega-3 nutritional deficiency that could affect their heart health and contribute to harmful inflammation, new research suggests.
Researchers at the University of Virginia School of Medicine and their collaborators have linked American Indigenous ancestry with an increased risk of omega-3 fatty acid deficiency among Hispanic Americans. Found in foods such as fatty fish and certain nuts, omega-3s are thought to be important in preventing heart disease and play an important role in the immune system.
Doctors can use the new findings, the researchers say, to identify Hispanic patients at risk of omega-3 deficiency and to help them correct the problem with nutritional guidance or supplements. This could help the patients avoid heart problems and other health issues down the road.
