Objective: The study aimed to determine the potential of compliance with Food-Based Dietary Guidelines (FBDG)and increased vitamin D fortification to meet the recommended intake level of vitamin D at 10 µg/day based on minimal exposure to sunlight. Methods: The main dietary sources of vitamin D were derived from national dietary surveys in adults from United Kingdom (UK) (n = 911 ), Netherlands (NL) (n = 1,526), and Sweden (SE) (n = 974). The theoretical increase in population vitamin D intake was simulated for the following: (1) compliance with FBDG, (2) increased level of vitamin D in commonly fortified foods, and (3) combination of both. Results: Median usual vitamin D intake was 2.4 (interquartile range 1.7-3.4) µg/day in UK, 3.4 (2.7-4.2) µg/day in NL, and 5.3 (3.9-7.3) µg/day in SE. The top 3 dietary sources of vitamin D were fish, fat-based spreads (margarines), and meat. Together, these delivered up to two-thirds of total vitamin D intake on average. Compliance with FBDG for fish, margarine, and meat increased vitamin D intake to 4.6 (4.1-5.1 ) µg/day in UK, 5.2 (4.9-5.5) µg/day in NL, and 7.7 (7.0-8.5) µg/day in SE. Doubling the vitamin D levels in margarines and milk would increase vitamin D intake to 4.9 (3.6-6.5) µg/day in UK, 6.6 (4.8-8.6) µg/day in NL, and 7.2 (5.2-9.8) µg/day in SE. Combining both scenarios would increase vitamin D intake to 7.9 (6.8-9.2) µg/day in UK, 8.8 (7.4-10.4) µg/day in NL, and 8.9 (6.9-11.8) µg/day in SE. Conclusion: This study highlights the potential of dietary measures to double the current vitamin D intake in adults. [ABSTRACT FROM AUTHOR]

The emerging field of prospective life cycle assessment (pLCA) offers opportunities for evaluating the environmental impacts of possible future consumption shifts. One such shift involves a transition from meat‐based to plant‐forward diets, acknowledged to mitigate environmental impacts of the food system under present day conditions. Current diets are often meat intensive (“meat‐based”), whilst “plant‐forward” diets include mainly plant‐based foods, encompassing flexitarian, vegetarian, and vegan diets. Here we illustrate the application of pLCA in a case study of meal options, implementing shared socio‐economic pathway scenarios in the LCA background system to represent future production conditions. We assess the climate footprints and land‐based biodiversity footprints of a typical meat‐based meal in Germany and Indonesia compared to a plant‐forward meal in both countries (i.e., four meals), now and in 2050. Our findings show that the plant‐forward alternative maintains a lower impact per serving in all future scenarios. At the same time, the reduction in impact for the meat‐based meals is more pronounced in future scenarios due to shifts in the agricultural system. Our findings highlight the importance of supply‐side measures to produce lower‐impact ingredients, complementing demand‐side interventions to reshape food consumption. Results are further evaluated in cultural and nutritional contexts, highlighting the practical decision‐making constraints faced by consumers. We find potential “leakage” effects in calories and nutrition when choosing a lower‐impact, plant‐forward meal. These leakage effects should be considered in future studies seeking to evaluate the environmental implications of meal substitutions in the context of broader dietary requirements.

Unilever is helping people to improve their health and wellbeing. Clear time-bound nutrition targets have been committed to in our Unilever Sustainable Living Plan and progress is reported annually. Our commitment to nutrition focusses on delivering products that are responsibly delicious and we inspire people to consume more nutritious diets. We developed our nutritional standards for reformulation, addressing the relevant nutrients of concern: saturated fat, trans fat, sodium, and sugar. In addition, we provide essential vitamins and minerals via our products, using a variety of high-quality ingredients or by adding micronutrients to commonly eaten foods via fortification. We are dialing up on plant-based offerings, like plant-based meat alternatives, dairy-free ice cream, and solutions for more plant-based meals. We empower people to consume more nutritious diets through our recipes and behavior change programs. We launched the Future 50 program that highlights 50 nutritious, plant-based ingredients for a more sustainable food system, which can be incorporated into daily meals. We run campaigns to inspire people to cook more nutritious meals, an example includes the program around our iron-fortified bouillon in Nigeria and Kenya. Reformulation and innovation do not come without challenges. We must consider the functionality of nutrients in the product, regulatory limitations, and consumer demand. The call for sustainable diets is clear and to make the dietary shift happen, as is needed for healthy diets within the boundaries of the planet, a strong multi-stakeholder approach is needed., (© 2020 S.
