Cost-Effectiveness of a New Nordic Diet as a Strategy for Health Promotion

Inappropriate diets constitute an important health risk and an increasing environmental burden. Healthy regional diets may contribute to meeting this dual challenge. A palatable, healthy and sustainable New Nordic diet (NND) based on organic products from the Nordic region has been developed. This study assesses whether a large-scale introduction of NND is a cost-effective health promotion strategy by combining an economic model for estimating the utility-maximizing composition of NND, a life cycle assessment model to assess environmental effects of the dietary change, and a health impact model to assess impacts on the disease burden. Consumer expenditure for food and beverages in the NND is about 16% higher than currently, with the largest relative difference in low-income households. Environmental loads from food consumption are 15%–25% lower, and more than 18,000 disability-adjusted life years (DALY) will be saved per year in Denmark. NND exhibits a cost-effectiveness ratio of about €73,000–94,000 per DALY saved. This cost-effectiveness improves considerably, if the NND’s emphasis on organic and Nordic-origin products is relaxed.

How to Obtain Forty Percent Less Environmental Impact by Healthy, Protein-Optimized Snacks for Older Adults

It is well known that meals containing less meat are more sustainable, but little is known about snack-meals, which typically do not contain meat. This study investigates the diversity in environmental impacts associated with snack production based on 20 common recipes optimized for protein content, energy content and sensory aspects for older adults. The purpose is to improve sustainability of public procurement by serving more sustainable snack-meals. Public procurement serves Danish older adults over millions of snack-meals every year, and millions more are served in countries with a similar social service. The environmental impact of snack production was estimated by consequential life cycle assessment. The average impact of producing the 10 least environmentally harmful snacks was 40% less than the average impact of producing the 10 most harmful snacks. This is true whether the functional unit was mass, energy, or protein content, and whether the environmental impact was measured as global warming potential or the monetized value of 16 impact categories. We conclude that large-scale public procurement of snack-meals by private and municipal kitchens can be reduced by up to 40% if the kitchens evaluate the environmental impact of all their snacks and serve the better half more frequently.

Organic food for sustainable and healthy diets - lessons from the nordic diet?

Introduction: In the last years and decades more and more new plants came to the market as food or old crops have been rediscovered. Based on the presence of secondary plant metabolites specific effects are often attributed to these plants and/or derived preparations. Depending on the amount and the accompanying substances in extracts and preparations these substances can also be toxic. In many cases, plants and plant preparations are not adequately tested for their safety before marketing. In the European Union, authorization procedures and health assessments are only required for foods that are considered novel foods or produced from genetically modified organisms. A working group of federal and state governments, the BfR has worked with, has drawn up a list of nearly 600 plants and plant parts, which should facilitate the assessment of these plants (or plant parts) and derived preparations by food inspection bodies and food industry. Objectives: 18 plants or parts of plants were selected for an evaluation because of their known pharmacological or psychotropic effects or due to possible health risks. Method / Design: The risk assessments of these plants or parts of plants, including for example goji berries and yohimbe bark, were performed using the “Guidance on Safety assessment of botanicals and botanical preparations intended for use as ingredients in food supplements” of the European Food Safety Authority (EFSA). Results: Nine of the 18 plants or parts of plants pose a risk to consumers and should not be used in food. Five plants or parts of plants might pose risks when used in food. For four plants or plant parts, no risks were seen. Conclusions: The health assessments are intended to be a first step in the process of harmonization at European level. The opinions are published in a booklet and accessible on the web(04/08/2019) Organic food for sustainable and healthy diets lessons from the nordic diet? Introduction: The New Nordic Diet (NND) was developed in 2004 by chefs and food professionals from the five Nordic countries. The goal for the NND was that it should be based on traditional regional food products but healthier than the traditional eating habits. The NND builds on four key principles: Nordic identity, health, gastronomic potential and sustainability.Objectives: Can the NND be used as a model for a sustainable diet in other geographical regions?Methods/design: The NND can be described by a few overall guidelines: 1) more calories from plant foods and fewer from meat; 2) more foods from the wild countryside and 3) more foods from sea and lakes. In many ways, the New NND is very similar to a Mediterranean diet but relies on rapeseed (canola) oil instead of olive oil and ramson instead of garlic. The diets differ in their types of produce due to regional differences in climate, soil and water.Results: The health effects and sustainability of the NND has been tested in a number of scientific studies, including the OPUS project (Optimal Well-Being, Development and Health for Danish Children through a Healthy New Nordic Diet) supported by the Nordea foundation (http://foodoflife.ku.dk/opus/english/nyheder/publikationer/) in which the NND was compared to the Average Danish Diet (ADD). The use of mostly local products and reduction of the meat intake were of both socioeconomic and environmental advantage. Including organic produce increased environmental impact of the NND.Conclusion: In line with the Mediterranean diet the NND is a predominantly plant-based diet, and although the two have not been directly compared, it would be fairly safe to assume that they are equally healthy. Overall, the NND is just a regional interpretation of the tenets of healthy eating. Basically the principles of the NND could be incorporated into any regional diet.Who are we eating with?

In control schools were 424 and in intervention schools 386 children (response rate 77%). Children filled in validated food frequency questionnaire assessing FV intake (times/day) and a validated questionnaire about factors influencing FV intake (availability of FV, liking for FV, preferences, self-efficacy to eat FV, attitudes towards FV and knowledge of the recommendations) both at baseline May 2009 and follow-up May 2010. Parental educational level (low, middle, high) was reported by the parents. Associations were examined with linear regression and mediation analyses.Results: The intervention increased fruit intake among girls but not among boys. Intervention increased also children’s knowledge of the recommendations. Since knowledge had no impact on boys’ fruit intake, the increase in knowledge mediated only intervention’s effect on girls’ fruit intake. Intervention increased children’s fruit intake similarly in all PEL groups.Intervention increased vegetable intake only in the middle PEL group but no intervention effect was noted among children with low or high PEL. Knowledge, the only factor which mediated the intervention’s effect on children’s vegetable intake, could not explain PEL differences in the effectivity of the intervention.Conclusions: Increase in knowledge was not a sufficient prerequisite to increase FV intake among boys or the lowest PEL group. More in depth analyses are needed to find out which factors to target in interventions to reach an effect in the target groups.
