Children's and adolescents' rising animal-source food intakes in 1990-2018 were impacted by age, region, parental education and urbanicity

Animal-source foods (ASF) provide nutrition for children and adolescents physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the worlds child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 1519 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes. (c) 2023, The Author(s)

Incident type 2 diabetes attributable to suboptimal diet in 184 countries

The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.814.4 million) incident T2D cases, representing 70.3% (68.871.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.027.1%)), excess refined rice and wheat intake (24.6% (22.327.2%)) and excess processed meat intake (20.3% (18.323.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.487.7%)) and Latin America and the Caribbean (81.8% (80.183.4%)); and lowest proportional burdens were in South Asia (55.4% (52.160.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally. (c) 2023, The Author(s)

Yields and greenhouse gas emissions of cultivation of red clover-grass leys as assessed by LCA when fertilised with organic or mineral fertilisers.

Red clover-grass leys were fertilized with cow manure or with chemical fertilizers. The yields were lower with organic fertilizers, but nevertheless the GHG emissions were lower per tonne of biomass in organic than in conventional conditions, even when the extra need for cultivation area to gain equal amounts of yield was considered.

Potential to reduce GHG emissions and land use by substituting animal-based proteins by foods containing oat protein concentrate

The potential to reduce GHG emissions and land use of the diet by replacing animal-based protein sources with foods containing oat protein concentrate (OPC) was analysed by life cycle assessment (LCA) of six different scenarios of daily food intake of one adult. The OPC was used in the preparation of bread and pasta and as a substitute for milk in yoghurt resulting in a higher protein content of these foods. The present study showed, that dietary-related GHG emissions and land use can be reduced by substituting animal-based proteins by foods containing oat protein. If the oat protein (OPC) enriched food items substitute animal based protein sources in the diet proportionally, GHG emission from the diet could be reduced by 8% and land use by 14%. However, if the OPC enriched food items are used specifically to replace intake of all beef and some pork, GHG emissions from the diet could be reduced by 13% and land use by 26%. Thereby, use of new plant-based protein ingredients in diets has a considerable potential to mitigate climate change and reduce land use. Even though the presented scenarios are extreme, they clearly demonstrate the potential that OPC food products made it possible to replace some of the animal-based protein with this plant-based protein source.</p
