 This study aimed to characterize global changes in dietary patterns from 1990 to 2010, assessing heterogeneity by age, sex, national income, and type of dietary pattern. The authors evaluated global consumption of key dietary items by region, nation, age, and sex using data from 325 surveys covering 88.7% of the global adult population. They found that diets based on healthy items improved globally, by 2.2 points, while diets based on unhealthy items worsened, minus 2.5 points. The study also showed that better diets were seen in older adults and women, and that high-income nations had better diets based on healthy items, but poorer diets based on unhealthy items compared to low-income nations. Dietary patterns were very heterogeneous across the world regions, with some improvement and worsening in different countries and regions. The authors concluded that these global data provide the best estimates to date of nutrition transitions across the world and inform policies and priorities for reducing the health and economic burdens of poor diet quality.
