Specific types of dairy products may be differentially associated with atherosclerotic cardiovascular disease (CVD). We conducted a systematic review and meta-analysis of cohort studies to summarize findings on the associations between total dairy product intake and intake of dairy product subgroups and the risk of major atherosclerotic CVDs in the general adult population. Our protocol was registered in PROSPERO (CRD42019125455). PubMed and Embase were systematically searched through 15 August 2019. For high versus low intake and dose-response meta-analysis, random-effects modelling was used to calculate summary risk ratios (RR). There were 13 cohort studies included for coronary heart disease (CHD), 7 for ischemic stroke and none for peripheral artery disease. High-fat milk was positively associated with CHD (RR 1.08 (95% confidence interval 1.00-1.16) per 200 g higher intake/day) and cheese was inversely associated with CHD (RR 0.96 (95% confidence interval 0.93-0.98) per 20 g higher intake/day). Heterogeneity, however, was observed in high versus low meta-analyses. Milk was inversely associated with ischemic stroke in high versus low meta-analysis only. In conclusion, this systematic review indicates a positive association of high-fat milk and an inverse association of cheese with CHD risk. The findings should be interpreted in the context of the observed heterogeneity.

Background/objectives: Excessive intake of sodium is a dietary risk factor for morbidity and mortality. Currently, intake of sodium is much higher than the recommended level in most western countries, and effective strategies to reduce population sodium intake are lacking. The objective of the present study was to investigate the effect of two different sodium reduction strategies on the intake of sodium, potassium, and the sodium to potassium ratio among Danish families SUBJECTS/METHODS: The study was a 4-month, single-blinded, cluster randomized controlled trial with a parallel design. Eighty-nine healthy Danish families, with a minimum of one child and one parent (n = 309), were randomly assigned to receive sodium-reduced bread (Intervention A), sodium-reduced bread and dietary counseling (Intervention B) or regular sodium bread (Control). The primary outcome was change in daily sodium intake, measured by 24-h urinary sodium excretion. Secondary outcomes included changes in dietary potassium and the sodium to potassium ratio., Results: No significant differences in daily sodium intake were observed in the two intervention groups compared with the control. When analyzing the results separately for children and adults, a reduction in dietary sodium of 0.6 g/day (-1.0, -0.2), p = 0.005 occurred among adults in intervention B compared with control., Conclusions: This study demonstrates that providing sodium-reduced bread in combination with dietary counseling is an effective strategy to reduce dietary sodium among adults, but the effect is lacking in children. The study was not able to show significant effects when providing sodium-reduced bread alone in neither adults nor children.

Background: Glycemic load (GL) reflects the quantity and quality of carbohydrates in the diet; dietary fiber and added sugar are components of GL. Few epidemiologic studies have assessed the association between these dietary factors and fecundability., Objective: We prospectively evaluated the associations of GL, total carbohydrates, dietary fiber, and added sugar with fecundability., Methods: Snart Foraeldre (SF) and Pregnancy Study Online (PRESTO) are parallel web-based prospective preconception cohorts of couples attempting to conceive in Denmark and North America. At baseline, female participants completed a web-based questionnaire on demographic and lifestyle factors and a validated FFQ. We calculated GL, total carbohydrate intake, total dietary fiber, carbohydrate-to-fiber ratio, and added sugar based on reported frequencies for individual foods, standard recipes for mixed foods, and average serving sizes. The analysis included 2709 SF participants and 4268 PRESTO participants. We used proportional probabilities regression models to estimate fecundability ratios (FR) and 95% CIs., Results: Compared with an average daily GL of ≤100, FRs for an average daily GL of ≥141 were 0.89 (95% CI: 0.73, 1.08) in SF and 0.87 (95% CI: 0.77, 0.98) in PRESTO participants. Compared with consuming ≤16 g/d of dietary fiber, FRs for consuming ≥25 g/d were 0.99 (95% CI: 0.81, 1.22) in SF and 1.06 (95% CI: 0.94, 1.20) in PRESTO. Compared with a carbohydrate-to-fiber ratio of ≤8, FRs for a ratio of ≥13 were 0.86 (95% CI: 0.73, 1.01) in SF and 0.87 (95% CI: 0.78, 0.98) in PRESTO. Compared with ≤27 g/d of added sugar, FRs for ≥72 g/d were 0.87 (95% CI: 0.68, 1.10) in SF and 0.86 (95% CI: 0.75, 0.99) in PRESTO participants., Conclusions: Among women attempting to conceive in Denmark and North America, diets high in GL, carbohydrate-to-fiber ratio, and added sugar were associated with modestly reduced fecundability., (Copyright © The Author(s) 2020.)

Background: Systematic reviews (SRs) constitute a major part of the Nordic Nutrition Recommendations (NNRs). The step-by-step procedure used to develop SRs has evolved considerably over time and is often tailored to fit the exposure and outcomes in focus., Objective: To describe a detailed procedure for developing qualified SRs commissioned by the NNR2022 project., Design: Scrutinizing procedures of recent SRs commissioned by leading national food and health authorities or international food and health organizations., Results: The following eight steps must be included when developing qualified SRs for the NNR2022 project: 1) define research question, 2) protocol development, 3) literature search, 4) screening and selection of studies, 5) data extraction, 6) assessing risk of bias, 7) synthesis and grading of total strength of evidence, and 8) reporting according to certain standards., Discussion: This guide is based on the guidelines developed for the fifth edition of NNR but includes some important new domains in order to adhere to more recent, authoritative standards., Conclusion: All qualified SRs in the NNR2022 project will follow the protocol described here., Competing Interests: See sections on “Conflicts of interest” and “Sponsors of the NNR2022 project” in the main text of the companion article (1)., (© 2020 Erik Kristoffer Arnesen et al.)

Objectives: The aim of the present study was to examine dietary habits and adherence to dietary recommendations in adult patients with type 1 diabetes (T1D) and type 2 diabetes (T2D) compared with the general population in Denmark., Methods: The study was cross-sectional and included 426 patients with T1D and 348 patients with T2D recruited from an outpatient diabetes clinic in the capital region of Denmark. Dietary habits were assessed by a food frequency questionnaire and compared with dietary data from 2,899 participants without diabetes from the Danish National Survey of Dietary Habits and Physical Activity., Results: Patients with diabetes had a 20-50% lower intake of added sugar and alcohol, and a 10-20% higher intake of fibre and vegetables compared with the general population (p<0.001 for all). Patients with T2D had a 37% lower intake of alcohol compared with T1D (p<0.001). Adherence to dietary recommendations (e.g. fibre, saturated fat, vegetables, fruit and fish) were low in all groups but lowest in the general population., Conclusion: The Danish diet is too high in saturated fat and too low in dietary fibre, vegetable, fruit and fish compared to dietary recommendations in both patients with diabetes and the general population. However, our data demonstrate that patients with diabetes consume a healthier diet compared to the general population: Limiting the intake of added sugar and alcohol, and increasing the intake of vegetables and dietary fibre., (Copyright © 2018 Elsevier Inc.

Purpose: Celiac disease, an immunological response triggered by gluten, affects ~1 % of the Western population. Information concerning gluten intake in the general population is scarce. We determined intake of gluten from wheat, barley, rye and oat in the Danish National Survey of Diet and Physical Activity 2005-2008. The study population comprised a random cross-sectional sample of 1494 adults 20-75 years, selected from the Danish Civil Registration System., Methods: Protein content in wheat, rye, barley and oat was determined from the National Danish Food Composition Table and multiplied with the amount of cereal used in recipes. Amount of gluten was calculated as amount of cereal protein ×0.80 for wheat and oat, ×0.65 for rye and ×0.50 for barley. Dietary intake was recorded daily during seven consecutive days in pre-coded food diaries with open-answer possibilities., Results: Mean total gluten intake was 10.4 ± 4.4 g/day (10th-90th percentiles; 5.4-16.2 g/day), in men 12.0 ± 4.6 g/day and 9.0 ± 3.4 g/day in women. It was higher among men than among women in all age groups (20-75 years; P < 0.0001); however, this difference was eliminated when adjusting for energy intake. Intake of different gluten sources tended to be higher in men than in women with the exception of gluten from barley. Total gluten intake decreased with increasing age (P < 0.0001) as did gluten intake from wheat (P < 0.0001), whereas intake of gluten from rye (P < 0.0001) and barley (P = 0.001) increased with increasing age, also when adjusted for energy intake or body weight., Conclusion: This study presents representative population-based data on gluten intake in Danish adults. Total gluten intake decreased with increasing age.

Fe deficiency is still common in infancy, even in affluent societies, and has prompted Fe fortification of food products and use of Fe supplements in many populations. In the present study, we tested the hypothesis that Fe status among 9-month-old infants following the Danish Fe supplementation recommendation (>400 ml Fe-fortified formula or 8 mg Fe/d) is associated with more favourable levels of Fe status indicators compared to those not following the recommendation. A random sample of 9-month-old infants living in Copenhagen was established and 312 healthy term infants were examined at 9·1 (sd 0·3) months of age. Blood samples were available from 278 infants. Overall, twenty infants (7·8 %) had Fe deficiency (serum ferritin < 12 μg/l) and < 1 % had Fe deficiency anaemia (serum ferritin < 12 μg/l and Hb < 100 g/l). Serum ferritin was positively associated with birth weight (P < 0·001), intake of fortified formula and follow-on formula (P = 0·001), and female sex (P < 0·001). Cow's milk intake and length of exclusive breast-feeding were negatively associated with Hb levels (P = 0·013 and P < 0·001). Serum ferritin levels were significantly higher (P < 0·0001) and transferrin receptor (TfR) was significantly lower (P = 0·003) among infants (n 188) meeting the Fe supplementation recommendation compared to those (n 67) not meeting the recommendation. No significant difference between these two groups was found for Hb. In conclusion, this study confirmed that Fe status of infants following the Danish Fe supplementation recommendation was significantly associated with increased serum ferritin and decreased levels of TfR indicating more favourable Fe status, compared to infants not following the recommendation.

Objective: To test whether there are differences in diet diversity between children still being partly breast-fed at 9 months and those completely weaned at the same age., Design: Cross-sectional study., Setting: Cross-sectional study (SKOT cohort) in the area of Copenhagen, Denmark., Subjects: Healthy term infants (n 312) at 9 months of age (mean 9·1 (SD 0·3) months)., Results: The infants partly breast-fed (n 168) at 9 months had significantly lower body weight (P < 0·0001), were significantly shorter (P = 0·0022) and were introduced to complementary foods significantly later (P < 0·0001) than completely weaned infants (n 141) of similar age. Furthermore, they had lower intake of energy, both in absolute amount (P < 0·0001) and per kilogram of body weight (P = 0·049). Significantly lower intakes of most energy-yielding nutrients, in absolute amounts and as energy percentages, were seen for the partly breast-fed compared with the completely weaned infants. These differences appear to be caused primarily by differences in the type and amount of milk consumed, as the energy derived from sources other than milk was similar except for fatty spread and vegetables as a side dish. Only small differences were found for absolute intakes of foods between feeding groups, although fatty spread had significantly higher intake rates and consumption (P = 0·031) among partly breast-fed compared with completely weaned infants., Conclusions: At 9 months the infants partly breast-fed did not eat a less diversified diet compared with those completely weaned at the same age. Despite later introduction to complementary foods compared with the completely weaned, their intake of foods was similar and no delay in their progression towards the family foods was noted.
