Food, Fatty Acids and Antioxidants Intake and their Associations with Atopic disease in Adults

It was hypothesized that high fat consumption, specifically from polyunsaturated fatty acids, may be positively related to atopic disease prevalence. On the other hand, antioxidants constituents of the diet may exert a protective effect against disorders related to the immune system. The aim of the present cross-sectional study was to assess the relationship between dietary intake of selected foods, fatty acids, and dietary antioxidants with atopic disease prevalence in adults. Data from the European Community Respiratory Health Survey in Erfurt, combined with a three-day weighed records from the MONICA dietary survey, was used. Complete data was available from 469 men and 333 women aged between 20 and 64 years. Multiple logistic regression was applied comparing the highest with the lowest quartile of dietary exposures and linear trends were tested stratified by gender. In men, margarine intake and a high ratio of omega-6 to omega-3 fatty acids were positively associated with hay fever (p for trend 0.03 and 0.04 respectively). In women, a high intake of total fat, palmitoleic and oleic acids were positively associated with sensitisation (aOR 2.42, p for trend 0.11, 3.04, p for trend 0.02, 2.47, p for trend 0.03 respectively). A high total fat (aOR 4.51, p for trend 0.05), high monounsaturated fatty acids (aOR 3.04, p for trend 0.01), and high oleic acid consumption (aOR 4.99, p for trend 0.01) were positively associated with hay fever. No clear relationships between antioxidant nutrients consumption and allergic disease were observed. Whilst an excessive intake of fat or imbalance in fat intake, particularly of monounsaturated fatty acids, increased the risk for hay fever and allergic sensitisation in women. Mainly, no significant associations were found for men. Dietary factors were mostly not related with prevalence rates of bronchial hyperresponsiveness and atopic eczema neither in men nor in women

Dietary Intake of Natural Sources of Docosahexaenoic Acid and Folate in Pregnant Women of Three European Cohorts

Background: Folic acid plays a fundamental role in cell division and differentiation. Docosahexaenoic acid (DHA) has been associated with infantile neurological and cognitive development. Thus, optimal intrauterine development and growth requires adequate supply of these nutrients during pregnancy. Methods: Healthy pregnant women, aged 18-41 years, were recruited in Granada (Spain; n = 62), Munich (Germany; n = 97) and Pecs (Hungary; n = 152). We estimated dietary DHA and folate intake in weeks 20 (w20) and 30 of gestation (w30) using a food frequency questionnaire with specific focus on the dietary sources of folate and DHA. Results: Both w20 and w30 Spanish participants had significantly higher daily DHA intakes (155 +/- 13 and 161 +/- 9 mg/1,000 kcal) than the German (119 +/- 9 and 124 +/- 12 mg/1,000 kcal; p = 0.002) and Hungarian participants (122 +/- 8 and 125 +/- 10 mg/1,000 kcal; p = 0.005). Hungarian women had higher folate intakes in w20 and w30 (149 +/- 5 and 147 +/- 6 mu g/1,000 kcal) than Spanish (112 +/- 2 and 110 +/- 2 mu g/1,000 kcal; p < 0.001) and German participants (126 +/- 4 and 120 +/- 6 mu g/1,000 kcal; p < 0.001), respectively. Conclusion: Dietary DHA and folate intake of pregnant women differs significantly across the three European cohorts. Only 7% of the participants reached the recommended folate intake during pregnancy, whereas nearly 90% reached the DHA recommended intake of 200 mg per day. Copyright (C) 2008 S. Karger AG, Base

Nutritional Recommendations for Healthcare and Essential Personnel Exposed to COVID-19 in Latin America

Estas recomendaciones se basan en la evidencia científica actual derivada de meta-análisis y revisiones sistemáticas sobre nutrición y prevención de infecciones respiratorias causadas por los virus SARS-CoV, MERS-CoV o influenza, similares en su estructura al SARS-CoV-2. Están dirigidas al personal en la primera línea de atención de salud y al personal que presta servicios esenciales a la comunidad, con alto riesgo de infección por la COVID-19. Estas personas usan equipo de protección personal, cumplen largos turnos laborales, en ocasiones bajo condiciones extremas, lo que puede llevar a descanso insuficiente, alto nivel de estrés, depresión, pobre calidad en la alimentación y deshidratación. Todos estos factores influyen negativamente en el sistema inmune y podrían conllevar un mayor riesgo de infección. Una ingesta adecuada de micronutrientes y otros compuestos bioactivos es esencial para el desempeño óptimo del sistema inmune. Existe evidencia moderada que avala la suplementación, en forma individual, con vitamina C (2 000 mg), vitamina D (1 000-2 000 UI) y zinc (≤ 40 mg) en la prevención de infecciones respiratorias en adultos. No se encontró evidencia suficiente para avalar la suplementación con vitamina A, niacina, ácido fólico, B12, omega 3, probióticos y polifenoles, aunque si se recomienda el consumo de alimentos ricos en estos nutrientes para apoyar al sistema inmune. Se recomienda al personal seguir la recomendación de consumir 5 porciones/día (400 g) de frutas y vegetales/hortalizas, mantenerse hidratado y limitar la cafeína. No hay evidencia del consumo de alimentos alcalinos para prevenir infecciones. Estas recomendaciones son particularmente importantes durante la pandemia.These recommendations are based on current scientific evidence obtained through meta-analysis and systematic reviews on nutrition and the prevention of respiratory infections related to SARS-CoV, MERS-CoV or influenza, similar in structure to SARS-CoV-2. They are aimed at primary health care personnel and to those who provide essential services to the community and are, consequently, at high risk of COVID-19 infection. These individuals wear personal protective equipment, work long shifts, sometimes under extreme conditions, which can lead to insufficient rest, high stress levels, depression, poor nutrition and dehydration. Together, these factors have a negative impact on the immune system and could result in an increased risk of infection. An adequate intake of micronutrients and other bioactive compounds is essential for optimal immune performance. There is moderate evidence supporting supplementation, individually, with vitamin C (2 000 mg), vitamin D (1 000-2 000 IU) and zinc (≤40 mg) for the prevention of respiratory infections in adults. Insufficient evidence was found to support supplementation with vitamin A, niacin, folic acid, B12, omega 3, probiotics and polyphenols; however, the consumption of foods rich in these nutrients is recommended to support immune function. It is recommended that workers follow the recommendation of consuming 400 g/day of fruits and vegetables, remain hydrated and limit caffeine. There is no scientific evidence supporting the consumption of alkaline foods to prevent infections. The aforementioned recommendations are particularly relevant during the pandemic.publishedVersionFil: Palacios, Cristina. Florida International University; United States.Fil: Bernal, Jennifer.

Polyunsaturated fatty acid intake and prevalence of eczema and rhinoconjunctivitis in Japanese children: The Ryukyus Child Health Study

<p>Abstract</p> <p>Background</p> <p>The recent increase in the prevalence of allergic disorders might be a consequence of increased intake of n-6 polyunsaturated fatty acids (PUFAs) and reduced intake of n-3 PUFAs. The current cross-sectional study examined the association between intake levels and the prevalence of eczema and rhinoconjunctivitis in Japanese children.</p> <p>Methods</p> <p>Subjects were 23,388 schoolchildren aged 6-15 years residing in Okinawa. The presence of eczema and/or rhinoconjunctivitis was determined according to the criteria of the International Study of Asthma and Allergies in Childhood. A brief diet history questionnaire for children and adolescents was administered to acquire information on dietary factors. Adjustment was made for age, sex, residential municipality, number of siblings, smoking in the household, body mass index, paternal and maternal history of allergic diseases, and paternal and maternal educational level.</p> <p>Results</p> <p>The prevalences of eczema and rhinoconjunctivitis in the previous 12 months were 7.0% and 8.0%, respectively. Consumption of PUFAs, n-3 PUFAs, α-linolenic acid, n-6 PUFAs, and linoleic acid was positively associated with the prevalence of eczema: the adjusted odds ratios (ORs) between extreme quintiles (95% confidence intervals [CIs], <it>P </it>for trend) were 1.26 (1.07-1.48, 0.04), 1.31 (1.11-1.54, 0.009), 1.31 (1.12-1.55, 0.003), 1.26 (1.07-1.48, 0.01), and 1.27 (1.08-1.49, 0.01), respectively. Arachidonic acid intake was independently inversely related to eczema: the adjusted OR between extreme quintiles was 0.81 (0.69-0.95, 0.0008). Eczema was not associated with eicosapentaenoic or docosahexaenoic acid intake, or with the ratio of n-3 to n-6 PUFA intake. Only arachidonic acid intake was statistically significantly related to the prevalence of rhinoconjunctivitis, showing a clear inverse linear trend: the adjusted OR between extreme quintiles was 0.86 (0.74-0.997, 0.03).</p> <p>Conclusions</p> <p>Consumption of n-3 and n-6 PUFAs, especially α-linolenic acid and linoleic acid, may be positively associated with eczema. Arachidonic acid intake may be inversely related to eczema and rhinoconjunctivitis.</p

Micronutrient recommendations for vulnerable groups in context of undernutrition, during the COVID-19 pandemic in Latin America

La crisis por COVID-19 (SARS-CoV-2) puede convertirse en una catástrofe alimentaria para Latinoamérica, aumentando las personas que padecen hambre de 135 a 265 millones, especialmente en Venezuela, Guatemala, Honduras, Haití y El Salvador, que ya enfrentaban crisis económicas y sanitarias. Este manuscrito presenta la posición de un grupo de expertos latinoamericanos sobre las recomendaciones de consumo y/o suplementación con vitamina A, C, D, zinc, hierro, folatos y micronutrientes múltiples, en contextos de desnutrición, para grupos vulnerables: mujeres embarazadas y lactantes, niñas y niños menores de 5 años y adultos mayores. Las recomendaciones buscan disminuir el impacto potencial que tendrá COVID-19 en el estado nutricional, durante la pandemia. La posición surge de la discusión de dichos expertos con base a la revisión de evidencia científica actual para estos grupos vulnerables. Está dirigida a tomadores de decisiones, encargados de políticas públicas, personal de salud y organismos de la sociedad civil. Después de la lactancia materna y una dieta suficiente en cantidad y calidad, la suplementación con los micronutrientes presentados, puede contribuir a prevenir y tratar enfermedades virales, reforzar el sistema inmune y reducir complicaciones. La lactancia materna con medidas de higiene respiratoria, el suministro de múltiples micronutrientes en polvo para niños desde los 6 meses hasta los 5 años y el aporte de hierro y folatos o micronutrientes múltiples para la embarazada, son estrategias comprobadas y eficaces que deben seguirse implementando en tiempos de COVID-19. Para los adultos mayores la suplementación con vitamina C, D y zinc puede estar indicada.The COVID-19 crisis (SARS-CoV-2) might transform into a food catastrophe in Latin America and would increase the number of people suffering from hunger from 135 to 265 million, particularly in Venezuela, Guatemala, Honduras, Haiti and El Salvador, already facing economic and health crises. This manuscript presents the position of a group of Latin American experts in nutrition for establishing the recommendations for consumption and / or supplementation with vitamin A, C, D, zinc, iron, folates and multiple micronutrients, in undernutrition contexts, for vulnerable population of pregnant and lactating women, children under 5 years and the elderly. The recommendations seek to decrease the potential impact that COVID-19 will have on nutritional status during the pandemic. The position arises from the discussion of the experts based on the review of current scientific evidence for these vulnerable groups. It aims to reach stakeholders, public policy makers, health personnel and civil society organizations. Only after breastfeeding and a sufficient diet in terms of quantity and quality, a supplementation with the micronutrients mentioned above can help prevent and treat viral diseases, strengthen the immune system and even reduce complications. Breastfeeding with respiratory higiene measures, the provision of multiple micronutrients powders for children from 6 moths to 5 years of age and the supply of iron and folates or multiple micronutrients tablets for pregnant women are proven and effective strategies that must continue to be implemented during COVID-19 pandemic. For older adults, supplementation with vitamin C, D and zinc might be indicated.publishedVersionFil: Bonvecchio Arenas, Anabelle. Instituto Nacional de Salud Pública; México.Fil: Bernal, Jennifer.

Dietary meat and fat intake and prevalence of rhinoconjunctivitis in pregnant Japanese women: baseline data from the Kyushu Okinawa Maternal and Child Health Study

<p>Abstract</p> <p>Background</p> <p>Dietary fat exerts numerous complex effects on proinflammatory and immunologic pathways. Several epidemiological studies have examined the relationships between intake of fatty acids and/or foods high in fat and allergic rhinitis, but have provided conflicting findings. The current cross-sectional study investigated such relationships in Japan.</p> <p>Methods</p> <p>Study subjects were 1745 pregnant women. The definition of rhinoconjunctivitis was based on criteria from the International Study of Asthma and Allergies in Childhood. Information on dietary factors was collected using a validated self-administered diet history questionnaire. Adjustment was made for age; gestation; region of residence; number of older siblings; number of children; smoking; secondhand smoke exposure at home and at work; family history of asthma, atopic eczema, and allergic rhinitis; household income; education; and body mass index.</p> <p>Results</p> <p>The prevalence of rhinoconjunctivitis in the past 12 months was 25.9%. Higher meat intake was significantly associated with an increased prevalence of rhinoconjunctivitis: the adjusted odds ratio between extreme quartiles was 1.71 (95% confidence interval: 1.25-2.35, <it>P </it>for trend = 0.002). No measurable association was found between fish intake and rhinoconjunctivitis. Intake of total fat, saturated fatty acids, monounsaturated fatty acids, n-3 polyunsaturated fatty acids, α-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid, n-6 polyunsaturated fatty acids, linoleic acid, arachidonic acid, and cholesterol and the ratio of n-3 to n-6 polyunsaturated fatty acid intake were not evidently related to the prevalence of rhinoconjunctivitis.</p> <p>Conclusions</p> <p>The current results suggest that meat intake may be positively associated with the prevalence of rhinoconjunctivitis in young adult Japanese women.</p

Food and fatty acid intake and atopic disease in adults.

The aim of the study was to assess the relationship between dietary intake of selected foods and fatty acids with atopic disease prevalence in adults. Data from the European Community Respiratory Health Survey in Erfurt, combined with a 3‐day weighed records dietary survey, was used. Complete data was available from 469 males and 333 females aged 20&ndash;64 yrs. Multiple logistic regression was applied comparing the highest with the lowest quartile of dietary exposures and linear trends were tested stratified by sex. In males, margarine intake and a high ratio of omega‐6 to omega‐3 fatty acids were positively associated with hay fever. In females, a high intake of total fat, palmitoleic and oleic acids were positively associated with sensitisation. A high total fat, high monounsaturated fatty acid and high oleic acid consumption were positively associated with hay fever. Whilst an excessive intake of fat or imbalance in fat intake, particular of monounsaturated fatty acids, increased the risk for hay fever and allergic sensitisation in females, mostly no significant associations were found for males. Dietary factors were mostly not related with prevalence rates of bronchial hyperresponsiveness and atopic eczema either in males or in females
