Global dietary quality in 185 countries from 1990 to 2018 show wide differences by nation, age, education, and urbanicity
Evidence on what people eat globally is limited in scope and rigour, especially as it relates to children and adolescents. This impairs target setting and investment in evidence-based actions to support healthy sustainable diets. Here we quantified global, regional and national dietary patterns among children and adults, by age group, sex, education and urbanicity, across 185 countries between 1990 and 2018, on the basis of data from the Global Dietary Database project. Our primary measure was the Alternative Healthy Eating Index, a validated score of diet quality; Dietary Approaches to Stop Hypertension and Mediterranean Diet Score patterns were secondarily assessed. Dietary quality is generally modest worldwide. In 2018, the mean global Alternative Healthy Eating Index score was 40.3, ranging from 0 (least healthy) to 100 (most healthy), with regional means ranging from 30.3 in Latin America and the Caribbean to 45.7 in South Asia. Scores among children versus adults were generally similar across regions, except in Central/Eastern Europe and Central Asia, high-income countries, and the Middle East and Northern Africa, where children had lower diet quality. Globally, diet quality scores were higher among women versus men, and more versus less educated individuals. Diet quality increased modestly between 1990 and 2018 globally and in all world regions except in South Asia and Sub-Saharan Africa, where it did not improve
Global, regional, and national consumption of animal-source foods between 1990 and 2018: findings from the Global Dietary Database
Background
Diet is a major modifiable risk factor for human health and overall consumption patterns affect planetary health. We aimed to quantify global, regional, and national consumption levels of animal-source foods (ASF) to inform intervention, surveillance, and policy priorities.
Methods
Individual-level dietary surveys across 185 countries conducted between 1990 and 2018 were identified, obtained, standardised, and assessed among children and adults, jointly stratified by age, sex, education level, and rural versus urban residence. We included 499 discrete surveys (91·2% nationally or subnationally representative) with data for ASF (unprocessed red meat, processed meat, eggs, seafood, milk, cheese, and yoghurt), comprising 3·8 million individuals from 134 countries representing 95·2% of the world population in 2018. We used Bayesian hierarchical models to account for differences in survey methods and representativeness, time trends, and input data and modelling uncertainty, with five-fold cross-validation.
Findings
In 2018, mean global intake per person of unprocessed red meat was 51 g/day (95% uncertainty interval [UI] 48â54; region-specific range 7â114 g/day); 17 countries (23·9% of the world's population) had mean intakes of at least one serving (100 g) per day. Global mean intake of processed meat was 17 g/day (95% UI 15â21 g/day; region-specific range 3â54 g/day); seafood, 28 g/day (27â30 g/day; 12â44 g/day); eggs, 21 g/day (18â24 g/day; 6â35 g/day); milk 88 g/day (84â93 g/day; 45â185 g/day); cheese, 8 g/day (8â10 g/day; 1â34 g/day); and yoghurt, 20 g/day (17â23 g/day; 7â84 g/day). Mean national intakes were at least one serving per day for processed meat (â„50 g/day) in countries representing 6·9% of the global population; for cheese (â„42 g/day) in 2·3%; for eggs (â„55 g/day) in 0·7%; for milk (â„245 g/day) in 0·3%; for seafood (â„100 g/day) in 0·8%; and for yoghurt (â„245 g/day) in less than 0·1%. Among the 25 most populous countries in 2018, total ASF intake was highest in Russia (5·8 servings per day), Germany (3·8 servings per day), and the UK (3·7 servings per day), and lowest in Tanzania (0·9 servings per day) and India (0·7 servings per day). Global and regional intakes of ASF were generally similar by sex. Compared with children, adults generally consumed more unprocessed red meat, seafood and cheese, and less milk; energy-adjusted intakes of other ASF were more similar. Globally, ASF intakes (servings per week) were higher among more-educated versus less-educated adults, with greatest global differences for milk (0·79), eggs (0·47), unprocessed red meat (0·42), cheese (0·28), seafood (0·28), yoghurt (0·22), and processed meat (0·21). This was also true for urban compared to rural areas, with largest global differences (servings per week) for unprocessed red meat (0·47), milk (0·38), and eggs (0·20). Between 1990 and 2018, global intakes (servings per week) increased for unprocessed red meat (1·20), eggs (1·18), milk (0·63), processed meat (0·50), seafood (0·44), and cheese (0·14).
Interpretation
Our estimates of ASF consumption identify populations with both lower and higher than optimal intakes. These estimates can inform the targeting of intervention, surveillance, and policy priorities relevant to both human and planetary health.

Childrenâs and adolescentsâ rising animal-source food intakes in 1990â2018 were impacted by age, region, parental education and urbanicity
Animal-source foods (ASF) provide nutrition for children and adolescentsâ 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 worldâs 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 15â19 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.publishedVersio

Sugar-sweetened beverage intakes among adults between 1990 and 2018 in 185 countries
Sugar-sweetened beverages (SSBs) are associated with cardiometabolic diseases and social inequities. For most nations, recent estimates and trends of intake are not available; nor variation by education or urbanicity. We investigated SSB intakes among adults between 1990 and 2018 in 185 countries, stratified subnationally by age, sex, education, and rural/urban residence, using data from the Global Dietary Database. In 2018, mean global SSB intake was 2.7 (8 oz = 248 grams) servings/week (95% UI 2.5-2.9) (range: 0.7 (0.5-1.1) in South Asia to 7.8 (7.1-8.6) in Latin America/Caribbean). Intakes were higher in male vs. female, younger vs. older, more vs. less educated, and urban vs. rural adults. Variations by education and urbanicity were largest in Sub-Saharan Africa. Between 1990 and 2018, SSB intakes increased by +0.37 (+0.29, +0.47), with the largest increase in Sub-Saharan Africa. These findings inform intervention, surveillance, and policy actions worldwide, highlighting the growing problem of SSBs for public health in Sub-Saharan Africa.</p

Collagen-Mimetic Proteins with Tunable Integrin Binding Sites for Vascular Graft Coatings
Achieving graft endothelialization
following implantation continues
to be a challenge in the development of âoff-the-shelf,â
small-caliber, arterial prostheses. Coating grafts with biomolecules
to support the retention, migration, and differentiation of adherent
endothelial precursor cells (EPCs) is a promising approach toward
improving graft endothelialization. <u>D</u>esigner <u>C</u>ollagen Scl2-<u>2</u> with <u>1</u> integrin binding site per strand (DC2-1X) is a Streptococcus pyogenes-derived, collagen-like protein
that has previously been evaluated as a graft coating due to its ability
to resist platelet aggregation and to promote attachment and migration
of âlate outgrowthâ EPCs (EOCs). However, these prior
assessments were performed in the absence of physiological shear.
In addition, although DC2-1X coatings supported increased migration
rates relative to native collagen coatings, EOC attachment and spreading
remained inferior to collagen controls at all DC2-1X concentrations
assayed. Thus, the objectives of the present work were the following:
(1) to improve EOC attachment on DC2 coatings by modulating the number
and spacing of DC2 integrin binding sites (IBS) and (2) to evaluate
the retention, migration, and differentiation of adherent EOCs under
physiological shear stress. Using single point mutations, three novel
DC2 variants were generated containing either two IBS (DC2-2X) or
three IBS (DC2-3X1 and DC2-3X2) per strand. After initial evaluation
of the potential of each DC2 variant to support increased EOC attachment
relative to DC2-1X, DC2-2X and DC2-3X1 coatings were further assessed
under physiological shear for their capacity to promote EOC retention,
migration, and differentiation relative to DC2-1X and collagen controls.
An increase in the number of IBS from 1 to 3 significantly improved
EOC retention on DC2 coatings while also supporting increased average
migration rates. Moreover, EOCs on DC2-3X1 coatings showed increased
gene-level expression of intermediate endothelial cell differentiation
markers relative to collagen. Overall, the current results suggest
that DC2-3X1 warrants further investigation as a vascular graft coating
