Association of poultry consumption with cardiovascular diseases and all-cause mortality: a systematic review and dose response meta-analysis of prospective cohort studies.

According to previous cohort studies it is suggested that a high intake of poultry does not adversely affect cardiovascular disease (CVD) risk. Therefore, the aim of this systematic review and meta-analysis is to summarize and analyze the association between dietary poultry intake and the risk for CVDs, coronary heart disease (CHD), stroke and all-cause mortality (ACM). Twenty-four cohort studies were included, and the results showed a trivial inverse association for the highest vs. lowest intake category between poultry and ACM (risk ratio [RR] = 0.96; 95% CI: 0.93, 0.98; I2 = 5%). For all other outcomes no association was observed in the high vs. low intake meta-analysis. The results from the primary pooled data for each 100 g/d increase in poultry intake indicated no association for all outcomes. Further, the non-linear dose-response analysis showed some evidence for non-linearity between poultry consumption and risk for CVD and ACM. Additionally, substituting red and/or processed meat with poultry was inversely associated with the risk for ACM, CVDs, CHD and stroke. The certainty of evidence was rated as very low or low. This meta-analysis suggests that based upon the results from the substitution analyses poultry could be a healthier alternative to red and processed meat.Supplemental data for this article is available online at https://doi.org/10.1080/10408398.2021.1975092.

Traditional v. modern dietary patterns among a population in western Austria: associations with body composition and nutrient profile.

OBJECTIVE: The present study aimed to identify dietary patterns, compare dietary patterns regarding nutrient profile and investigate the association between dietary patterns and body composition in a population in western Austria. DESIGN: In a cross-sectional study, eating habits, anthropometric measurements and body composition were assessed. Food intake was collected by two non-consecutive 24 h recalls. Factor analysis (principal component analysis) with complementary cluster analysis was applied to identify dietary patterns. Associations of dietary patterns with body composition and nutrient profile were examined by the t test, one-way ANOVA and ANCOVA with Bonferroni's correction. The χ 2 test was used for categorical variables. SETTING: Tyrol, western Austria, 2014-2015.ParticipantsAdults (n 463) aged 18-64 years. RESULTS: Three dietary patterns were derived, labelled as the 'health-conscious', the 'western' and the 'traditional' dietary pattern. After adjustment for confounding variables, individuals following the traditional and western patterns were more likely to be overweight/obese (P <0·001) and to have a higher body fat percentage (P <0·05). Individuals following the traditional dietary pattern consumed significantly more SFA and less PUFA and dietary fibre (P <0·001) than those in the other groups. CONCLUSIONS: Individuals who mostly eat in a traditional way should be encouraged to increase their consumption of vegetables, fruits, whole grains and healthy fats. It is important to know local eating habits not only for planning individual nutritional therapy, but also for well-directed public health actions.

Zinc intake and status in Austria in the light of different reference values.

Zinc has been identified as a critical micronutrient also in high-income countries. There is still some uncertainty about the evaluation of zinc sufficiency due to divergent daily intake reference values. We wanted to exemplify this issue using data from the Austrian Study on Nutritional Status 2012. Plasma zinc concentrations were measured in a nationally representative sample of 872 persons aged 6-80 years (55.5 % female). Dietary zinc intake was estimated from two 24h dietary recalls. Additionally, parameters of the antioxidative status (plasma malondialdehyde (MDA), total antioxidative capacity) and activities of alkaline phosphatase (AP), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px)) were determined. Zinc status was marginal in schoolchildren (40 % of boys and 22 % of girls) and in elderly (28 % of men and 33 % of women). Dietary zinc intake was also unsatisfactory in these groups with 38 % of boys and 32 % of girls and 64.5 % of older men below the nationally recommended intake levels. However, the adequacy of zinc intake varied with different reference values. Adults were more likely to meet the D-A-CH reference values and those from the European Food Safety Authority than the recommendations of the International Zinc Nutrition Consultative Group (IZiNCG) and the Institute of Medicine, whereas children met the IZiNCG values best. Zinc status correlated weakly with AP activity (r = -0.298, p < 0.001) and some antioxidant status markers (CAT, MDA, GSH-PX, SOD), especially in the elderly (MDA: r = -0.527, p < 0.001, and SOD: r = -0.466, p = 0.002). Our results suggest a suboptimal zinc supply in Austria particularly among schoolchildren and older adults.

The Association of Potassium Status with Parameters of Glucose Metabolism is influenced by Age in Adults.

BACKGROUND: Potassium status has been found to affect glucose homeostasis. OBJECTIVE: This study therefore aimed at investigating relationships between potassium status or dietary intake and fasting plasma glucose (FPG) or glycated haemoglobin (HbA1c) in a sample of Austrian adults (18-80 years, n = 421, 61% women) from the Austrian Study on Nutritional Status 2012. METHODS: Dietary potassium intake was obtained by two 24 h recalls. FPG, plasma K+, and urinary K+ were determined photometrically, HbA1c by HPLC. Associations between the parameters were studied using multiple regression analysis after controlling for confounders and after age stratification of the sample (18-64 y vs. 65-80 y). RESULTS: Most of the participants had a potassium intake of less than the estimated adequate daily intake of 4000 mg/d. In the multiple regression analyses in the whole sample plasma K+ had a statistically significant positive effect on FPG only in the crude model (ß = 0.128, p < 0.01) and on HbA1c also in the fully adjusted model (ß = 0.129, p < 0.05). The small effects on HbA1c were also detected in the younger age group but were absent in the older population. However, in this latter, a reverse association of urinary K+ on HbA1c was observed as well as of dietary potassium intake on FPG with no effects in the younger sample. CONCLUSION: We suggest that age dependent differences in the association between parameters of potassium status and blood glucose regulation should also be taken into account.

Electrolyte Intake and Major Food Sources of Sodium, Potassium, Calcium and Magnesium among a Population in Western Austria.

Dietary intake of sodium, potassium, calcium and magnesium has a strong impact on personal health. In order to understand possible correlations with regional occurrence of diseases and to develop new dietary strategies, it is necessary to evaluate food choices in defined geographic areas. The aim of this study was to analyze daily consumption and major food sources of electrolytes with an emphasis on dietary patterns. In this representative, cross-sectional study, daily foods of 463 adults were assessed with two nonconsecutive 24-h recalls. Our results show high sodium and low potassium consumption in all age groups in both men and women. Furthermore, more than half of investigated persons had low calcium, and 40% indicated low dietary magnesium intake. Only 1% of our study population reached the recommended values for all electrolytes, while 13% consumed adequate levels of three electrolytes. Moreover, 14% did not reach reference levels for any of the four minerals. A further comparison of dietary patterns and food preferences showed significant differences in major food groups including nonalcoholic drinks, fruits, vegetables, legumes, milk products, vegetable oil, bread and sweets. Our results are important for further evaluations of nutrition intake and the development of new dietary strategies.

Main Sources, Socio-Demographic and Anthropometric Correlates of Salt Intake in Austria.

Excessive salt intake is known to increase blood pressure and cardiovascular risk. Nevertheless, salt intake exceeds the recommendations in most countries. To face this problem, it is important to identify high consumers as well as the main contributors of salt intake. Overall, data of 2018 adults between 18 and 64 years were analysed to determine the main sources, socio-demographic and anthropometric correlates of salt intake. Dietary intake was assessed from 24-h-recalls, information on socio-demographic characteristics was obtained using a questionnaire and anthropometric data were measured. Salt intake was significantly higher in males than in females. There was a significant positive association between salt intake and body mass index. No significant differences in salt intake were observed for other variables including affluence, educational level, smoking status and physical activity. The main contributor to salt intake were condiments including table salt (32.6%), followed by cereals and cereal products (27.0%), meat and meat products (16.1%) and dairy products (14.0%). These results highlight that specific population groups need to be targeted by public health initiatives and that a reduction in salt intake can only be achieved in tandem with the food producers by the reduction of salt in processed foods.
