According to WHO, in 2016, more than 1.9 billion adults, 18 years and older, were overweight. Of these over 650 million were obese. Overweight and obesity, as well as their related noncommunicable diseases, are largely preventable. Supportive environments and communities are fundamental in shaping people’s choices, by making the choice of healthier foods and regular physical activity the easiest choice. A research team has collaborated to develop the eNutri app, which aims to offer nutritional advice to encourage people to eat more healthily. The findings highlight a clear link between improved eating habits and the personalised nutritional advice supplied. The eNutri app gives an automated assessment of diet quality, giving the user a ‘healthy diet score’ out of 100. The ‘healthy diet score’ includes assessments of intake of fruit, vegetables, wholegrains, and red and processed meat, with higher points awarded when users have the recommended intake of these. The personalised advice is then targeted to areas of their diet that they would benefit most from changing.
