Revealed: the countries with the best and worst diets in the world

Eating plenty of fruit and veg, the citizens of Chad have world’s healthiest diet, while those in Armenia have the worst, according to new research comparing global eating habits.
The study revealed a worldwide rise in the consumption of healthy food, including fruit and vegetables, but this was overtaken by a worrying increase the amount of junk food being eaten.
To make their findings published in 'The Lancet Global Health' journal, researchers used national data from almost 90 per cent of the global population to analyse how people ate between 1990 and 2010.
 
 
They then assessed three dietary patterns. The first was based on ten healthy foods: fruits, vegetables, beans and legumes, nuts and seeds, whole grains, milk, total polyunsaturated fatty acids, fish, plant omega-3s, and dietary fibre.
The second was based on seven unhealthy foods: unprocessed red meats, processed meats, sugar-sweetened beverages, saturated fat, trans fat, dietary cholesterol, and sodium. The third was an overall assessment based on all 17 food groups.
Using this data, researchers scored countries between 0-100 – with a higher number indicating a healthier diet.
