Abstract
The moral imperative of public health systems is to maximize the health and welfare of the population to the extent possible. Constraints often include a lack of resources, political will, popular acceptance, or an acceptable safety margin. Major agencies have established iron, iodine, and vitamin A as the principal elements for micronutrients, with folate and zinc on the second plane. As the armamentarium of interventions to favor micronutrient nutrition, for example, preventive health measures, dietary improvement, forms of fortification, and nutrient supplements, is offered in public health policy. The utility of their merger with other nutrients, emergent nutrients, has been considered. The Latin America and Caribbean Region has unique characteristics. The scientific and epidemiology considerations for action in the Region's health concern on 4 emergent nutrient deficiencies of public health-vitamins D and E, essential fatty acids, and choline-are reviewed.

Abstract
In 2016, the first worldwide n3 PUFA status map was published using the Omega-3 Index (O3I) as standard biomarker. The O3I is defined as the percentage of EPA + DHA in red blood cell (RBC) membrane FAs. The purpose of the present study was to update the 2016 map with new data. In order to be included, studies had to report O3I and/or blood EPA + DHA levels in metrics convertible into an estimated O3I, in samples drawn after 1999. To convert the non-RBC-based EPA + DHA metrics into RBC we used newly developed equations. Baseline data from clinical trials and observational studies were acceptable. A literature search identified 328 studies meeting inclusion criteria encompassing 342,864 subjects from 48 countries/regions. Weighted mean country O3I levels were categorized into very low ≤4%, low >4-6%, moderate >6-8%, and desirable >8%. We found that the O3I in most countries was low to very low. Notable differences between the current and 2016 map were 1) USA, Canada, Italy, Turkey, UK, Ireland and Greece (moving from the very low to low category); 2) France, Spain and New Zealand (low to moderate); and 3) Finland and Iceland (moderate to desirable). Countries such as Iran, Egypt, and India exhibited particularly poor O3I levels.

Effect of age and dietary habits on Red Blood Cell membrane fatty acids in a Southern Europe population (Basque Country). Prostaglandins Leukot Essent Fatty Acids 2024; 200:102602. [PMID: 38147804 DOI: 10.1016/j.plefa.2023.102602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 12/10/2023] [Accepted: 12/12/2023] [Indexed: 12/28/2023]
Abstract
The levels of blood eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are very variable and, in general, low in most of the world population. In this study, the effects of age, sex, COVID-19, and dietary habits on the lipid profile of the erythrocyte membranes were assessed in a sub-cohort of healthy population (N = 203) from a large cohort of individuals from the Basque Country, Spain, (AKRIBEA). Sex did not have an effect on RBC lipid profile. COVID-19 infected participants showed higher levels of DGLA. Oldest participants showed higher oleic acid, EPA and DHA levels. Arachidonic acid in RBC correlated positively with the intake of sunflower oil, butter, eggs, processed and red meat, whereas DHA and EPA correlated positively with oily and lean fish. Basque Country population showed lipid profiles similar to other high fish consuming countries, such as Italy and Japan. Baseline levels of the whole lipidomic profile of the RBC including SFA, MUFA and PUFA should be examined to obtain a better description of the health and nutritional status.

DHA-enriched re-esterified triacylglycerol fish oil supplementation and oily fish consumption enhance red blood n-3 fatty acid index in Omani pre-adolescent schoolchildren. Prostaglandins Leukot Essent Fatty Acids 2018; 135:74-82. [PMID: 30103936 DOI: 10.1016/j.plefa.2018.07.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Revised: 07/09/2018] [Accepted: 07/09/2018] [Indexed: 12/18/2022]
Abstract
Dietary habits of Omani population particularly of children and young adults have changed significantly. Consumption of imported calorie-dense foods, vegetable oils, milled and polished grains and carbonated beverages have become the norm. Concomitantly, there has been an exponential increase in the prevalence of non-communicable diseases. The impact of the westernisation of eating habits on children has not been evaluated. We have investigated blood fatty acid profile of male (n = 125) and female (n = 160) children aged 9 and 10 (9.8 ± 0.4) years enrolled from three state-funded schools. The schools, which are homogenous with respect to socio-economic background of their pupils, were randomised into fish oil (n = 98), oily fish (n = 82) or control (n = 105) group. Subsequently, the children were given during morning tea break for 12 weeks: 1. DHA-enriched re-esterified triacylglycerol fish oil capsule with cheese/salad sandwich (fish oil group), 2. Lightly grilled oily fish with salad (fish group) or 3. Cheese/salad sandwich (control group). At baseline, the males had higher myristic, palmitic and oleic and lower adrenic acids than the females (p < 0.05). There was no difference in n-3 fatty acid index (4.86 ± 1.95 vs. 5.12 ± 1.67, p > 0.05) or AA (14.6 ± 1.9 vs. 14.9 ± 1.8, p > 0.05) between the genders. There was no difference in any of the fatty acids between the three groups at baseline. Post-intervention, the oily fish group had lower n-3 fatty acid index (EPA + DHA, 6.03 ± 1.39 vs. 6.60 ± 1.63, p < 0.05) and higher AA (15.2 ± 1.8 vs. 13.7 ± 2.0, p = 0.0001) and n-3 DPA (1.40 ± 0.27 vs. 1.07 ± 0.22, p = 0.0001) compared with those who received fish oil capsules. In both the fish oil and oily fish groups, fatty acid index correlated positively with AA (r = 0.394, p = 0.0001; r = 0.231, p = 0.038) and negatively with total saturated (r = - 0.816, p = 0.0001; r = - 0.439, p = 0.0001) and total mono-unsaturated (r = - 0.431, p = 0.0001; r = - 0.231, p = 0.037) fatty acids. Although seafood is an integral part of traditional Omani cuisine the children had a low level of n-3 fatty acids index. There is a need to address this nutritional insufficiency through school feeding programme, targeted intervention with n-3 fatty acid enriched food products and/or family education programme.

Prog Lipid Res 2016; 63:132-52. [PMID: 27216485 DOI: 10.1016/j.plipres.2016.05.001] [Citation(s) in RCA: 341] [Impact Index Per Article: 42.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 05/14/2016] [Accepted: 05/18/2016] [Indexed: 02/05/2023]
Abstract
Studies reporting blood levels of the omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), were systematically identified in order to create a global map identifying countries and regions with different blood levels. Included studies were those of healthy adults, published in 1980 or later. A total of 298 studies met all inclusion criteria. Studies reported fatty acids in various blood fractions including plasma total lipids (33%), plasma phospholipid (32%), erythrocytes (32%) and whole blood (3.0%). Fatty acid data from each blood fraction were converted to relative weight percentages (wt.%) and then assigned to one of four discrete ranges (high, moderate, low, very low) corresponding to wt.% EPA+DHA in erythrocyte equivalents. Regions with high EPA+DHA blood levels (>8%) included the Sea of Japan, Scandinavia, and areas with indigenous populations or populations not fully adapted to Westernized food habits. Very low blood levels (≤4%) were observed in North America, Central and South America, Europe, the Middle East, Southeast Asia, and Africa. The present review reveals considerable variability in blood levels of EPA+DHA and the very low to low range of blood EPA+DHA for most of the world may increase global risk for chronic disease.
