Very low Omega‐3 Index in young healthy students from Palestine

Abstract

AbstractOily fish is rich in long‐chain omega‐3 polyunsaturated fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have been associated with several health benefits. However, fish consumption is generally low in many countries, including the Middle East, resulting in low omega‐3 blood levels. In Palestine, no data on the omega‐3 blood status is available. The aim of this cross‐sectional study was to assess the omega‐3 status and related factors in young healthy subjects from Palestine. Omega‐3 status was assessed using the Omega‐3 Index—defined as the sum of EPA + DHA in relation to the total fatty acid content of erythrocytes. A total of 149 subjects, 50 males and 99 females (age range: 18–24 years), were included in the study. In addition to the Omega‐3 Index, data on anthropometrics, physical activity, smoking status, fish intake, dietary supplement intake, blood lipid profile, and whole erythrocyte fatty acid pattern were collected. The mean (SD) Omega‐3 Index was 2.56 (0.57)%, with 97.9% of subjects having an index below 4%. The majority of participants (91.8%) consumed less than two portions of fish per week, and only 4% reported taking omega‐3 supplements, mostly irregularly. Our findings show that young Palestinian students have an alarmingly low omega‐3 status. Further studies are needed to investigate whether the omega‐3 status is also low in the general Palestinian population.
