- The objective was to examine 10-year changes in dietary carbon footprint relative to individual characteristics and food intake in the unique longitudinal Vasterbotten Intervention Programme, Sweden. Here, 14 591 women and 13 347 men had been followed over time. Food intake was assessed via multiple two study visits 1996-2016, using a 64-item food frequency questionnaire. Greenhouse gas emissions (GHGE) related to food intake, expressed as kg carbon dioxide equivalents/1000 kcal and day, were estimated. Participants were classified into GHGE quintiles within sex and 10-year age group strata at both visits. Women and men changing from lowest to highest GHGE quintile exhibited highest body mass index within their quintiles at first visit, and the largest increase in intake of meat, minced meat, chicken, fish and butter and the largest decrease in intake of potatoes, rice and pasta. Women and men changing from highest to lowest GHGE quintile exhibited basically lowest rates of university degree and marriage and highest rates of smoking within their quintiles at first visit. Among these, both sexes reported the largest decrease in intake of meat, minced meat and milk, and the largest increase in intake of snacks and, for women, sweets. More research is needed on how to motivate dietary modifications to reduce climate impact and support public health.

- Abstract Objectives To assess 1) the association between adherence to the Swedish dietary guidelines and all-cause mortality, and 2) the difference in greenhouse gas emissions (GHGE) from diets of participants with higher and lower adherence to the Swedish dietary guidelines. Methods Dietary data from the Swedish population-based cohort Västerbotten Intervention Programme (49,124 women and 47,651 men, 35–65 years at baseline), collected between the years 1990–2016, were used. Diet quality was assessed by the Swedish Healthy Eating Index for Adults 2015 (SHEIA15). SHEIA15 is based on the Swedish dietary guidelines from 2015, and includes assessments of intakes of vegetables and fruits, seafood, whole grains, fiber, monounsaturated fatty acids, polyunsaturated fatty acids, saturated fatty acids, red and processed meat and added sugar. GHGE of diets were estimated from life cycle assessment data, including CO2e from primary production to industry gate. Information on all-cause mortality was acquired from registers at the National Board of Health and Welfare in Sweden using personal identification numbers. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox proportional hazards regression, comparing the lowest and highest quintile of SHEIA15 score. Potential confounders were adjusted for. Difference in GHGE of diets was compared between the lowest and highest quintile of SHEIA15 score, using the Mann Whitney U test. Results Median follow-up times were for women 16.0 years and for men 14.7 years, during which time 3074 women and 4212 men died. For women the highest SHEIA15 score was associated with lower mortality compared with the lowest score (HR: 0.87; 95% CI: 0.77, 0.98; P = 0.027). No statistically significant difference in HR of mortality was found for the men with the highest SHEIA15 score compared with the lowest score (HR: 0.91; 95% CI: 0.82, 1.01; P = 0.083). The participants with the highest score of SHEIA15 had lower dietary GHGE compared to those with the lowest score in both women and men (P < 0.001). Conclusions Higher adherence to the Swedish dietary guidelines, estimated by SHEIA15, was associated with lower all-cause mortality for women, but not for men, and indicated lower GHGE from diets for both women and men.

- Objective: To assess the associations between adherence to the Swedish dietary guidelines and all-cause mortality and thus assessing the index' ability to predict health outcomes, as well as levels of dietary greenhouse gas emissions (GHGEs). Design: A longitudinal study 1990-2016 within the population-based cohort Västerbotten Intervention Programme. Dietary data were based on food frequency questionnaires. Diet quality was assessed by the Swedish Healthy Eating Index for Adults 2015 (SHEIA15), based on the 2015 Swedish dietary guidelines. Dietary GHGEs were estimated from life cycle assessment data including emissions from farm to industry gate. Hazard ratios (HRs) and 95% confidence intervals (CIs) of all-cause mortality were evaluated with Cox proportional hazards regression, and differences in median GHGEs were tested using the Kruskal-Wallis one-way ANOVA test, between quintiles of SHEIA15 score. Setting: Northern Sweden. Participants: In total, 49,124 women and 47,651 men, aged 35-65 years. Results: Median follow-up times were 16.0 years for women and 14.7 years for men, during which time 3074 women and 4212 men died. A consistent trend of lower all-cause mortality HRs for both sexes with higher SHEIA15 scores was demonstrated. For women, the all-cause mortality HR was 0.81 [(95% CI 0.71-0.92); p=0.001] and for men 0.90 [(95% CI 0.81-0.996); p=0.041] between the quintile with the highest SHEIA15 score compared with the quintile with the lowest SHEIA15 score. A consistent trend of lower estimated dietary GHGEs among both sexes with higher SHEIA15 scores was also found. Conclusions: Adherence to Swedish dietary guidelines, estimated by SHEIA15, seems to promote longevity and reduce dietary climate impact. © The Authors 2023.

- Objective:The objective of this study was to examine climate impact from diet across background and sociodemographic characteristics in a population-based cohort in northern Sweden.Design:A cross-sectional study within the Västerbotten Intervention Programme. Dietary data from a 64-item food frequency questionnaire collected during 1996-2016 were used. Energy-adjusted greenhouse gas emissions (GHGE) for all participants, expressed as kg carbon dioxide equivalents/day and 4184 kJ (1000 kcal), were estimated using data from life cycle analyses. Differences in background and sociodemographic characteristics were examined between participants with low and high GHGE from diet, respectively. The variables evaluated were age, BMI, physical activity, marital status, level of education, smoking, and residence.Setting:Västerbotten county in northern Sweden.Participants:In total, 46 893 women and 45 766 men aged 29-65 years.Results:Differences in GHGE from diet were found across the majority of examined variables. The strongest associations were found between GHGE from diet and age, BMI, education, and residence (all P < 0·001), with the highest GHGE from diet found among women and men who were younger, had a higher BMI, higher educational level, and lived in urban areas.Conclusions:This study is one of the first to examine climate impact from diet across background and sociodemographic characteristics. The results show that climate impact from diet is associated with age, BMI, residence and educational level amongst men and women in Västerbotten, Sweden. These results define potential target populations where public health interventions addressing a move towards more climate-friendly food choices and reduced climate impact from diet could be most effective.

- Background: Diets combining adequate nutritional quality and low climate impact are highly needed for human and planet health. Objectives; We aimed to 1) evaluate nutrient density indexes' ability to predict mortality, and 2) assess the effects of diets varying in nutrient density and climate impact on total mortality. Methods: Dietary data from 49,124 women and 47,651 men aged 35-65 y in the population-based prospective study Vasterbotten Intervention Programme (Sweden) were used. Greenhouse gas emissions (GHGEs) were estimated using data from life cycle assessments. Fifteen variants of nutrient density indexes were evaluated and the index that best predicted mortality was used to estimate participants' nutrient density. GHGEs and nutrient density were adjusted for energy intakes. Total mortality risk was estimated by Cox proportional hazards models for 4 groups of women and men, respectively, i.e., higher nutrient density, lower climate impact (HNutr/LClim); higher nutrient density, higher climate impact (HNutr/HClim); lower nutrient density, lower climate impact (LNutr/LClim); and lower nutrient density, higher climate impact (LNutr/HClim-reference group). Results: NRF11.3, a Sweden-adapted variant of the Nutrient Rich Foods index, was identified to have the best ability to predict mortality in the study population. Median follow-up times for women and men were 16.0 and 14.7 y, respectively. For women a significantly lower mortality risk was found for HNutr/LClim (HR: 0.87; 95% CI: 0.79, 0.96; P = 0.008) and HNutr/HClim (HR: 0.87; 95% CI: 0.78, 0.97; P = 0.011) than for LNutr/HClim. Among men LNutr/LClim had a significantly higher mortality risk (HR: 1.10; 95% CI: 1.01, 1.21; P = 0.033) than LNutr/HClim. Conclusions: Diets beneficial for both health and climate are feasible and associated with lower mortality risk in women. Further studies are needed to understand how men may transition into diets that are more sustainable from a combined health and climate perspective.

- Background: Nutritional quality, and health and climate impacts are important considerations in the design of sustainable diets.Objectives: To investigate the association between diets varying in nutrient density and climate impact and MI and stroke HRs.Methods: Dietary data of 41,194 women and 39,141 men (35-65 y) who participated in a Swedish population-based cohort study were employed. Nutrient density was calculated using the Sweden-adapted Nutrient Rich Foods 11.3 index. Dietary climate impact was calculated with data from life cycle assessments, including greenhouse gas emissions from primary production to industry gate. HRs and 95% CIs for MI and stroke were assessed with multivariable Cox proportional hazards regression, comparing a least-desirable diet scenario reference group (lower nutrient density, higher climate impact) with three diet groups that varied with respect to higher/lower nutrient density and higher/ lower climate impact. Results: Median follow-up time from the baseline study visit to MI or stroke diagnosis was 15.7 y for women and 12.8 y for men. The MI hazard was significantly higher for the men with diets of lower nutrient density and lower climate impact (HR: 1.19; 95% CI: 1.06, 1.33; P 1/4 0.004), compared with the reference group. No significant association with MI was observed for any of the diet groups of women. No significant association with stroke was observed among any of the diet groups of women or men.Conclusions: The results among men suggest some adverse health effects for men when diet quality is not considered in the pursuit of more climate-sustainable diets. For women, no significant associations were detected. The mechanism underlying this association for men needs further investigation.
