 This study aimed to characterize global changes in dietary patterns and assess heterogeneity by age, sex, national income and type of dietary pattern. The authors evaluated global consumption of key dietary items, foods and nutrients by region, nation, age and sex in 1990 and 2010 using data from 325 surveys covering 88.7% of the global adult population. They found that diets based on healthy items improved globally from 1990 to 2010, while diets based on unhealthy items worsened. The study also found that better diets were seen in older adults and women compared with younger adults and men, respectively. Additionally, high-income countries had better diets based on healthy items but poorer diets based on unhealthy items compared to low-income nations. Dietary patterns and their trends were very heterogeneous across the world regions, with some improvement and worsening in different regions and countries. 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.
