Diets Around the World

Healthier diets are key to reducing non-communicable diseases but the data on dietary patterns has been weak. 

A new attempt to evaluate measures of dietary quality in 187 countries, by Fumiaki Imamura and colleagues and published in The Lancet Global Health, assessed 2 patterns: one with greater consumption of 10 healthy items, and another focused on 7 unhealthy items.

Higher national income was associated with better quality for the healthy dietary pattern, and with much worse quality for the unhealthy dietary pattern. Better diets were seen in older adults compared with younger adults, and in women compared with men.

Interestingly, some of the poorest countries in the world, such as Chad, was ranked as the country with the healthiest diet overall, because of limited access to processed food.
