British diets include insuffient fruit and vegetables, fibre and oily fish, and too much added sugar, salt and saturated fats. The average British adult consumes:

  • 4.1 portions of fruit and vegetables per day. Children consume around 3. 5 or more a day is recommended.
  • An estimated 18 g a day of fibre, compared to the recommended 30 g a day.
  • 8.1 g of salt per day, compared to the 6 g maximum. 80% of men and 58% of women exceed the guidelines, as do most children.
  • 12% of their energy from sugar compared to the recommended 5%.

Lower levels of income and education are associated with less healthy diets. While diet is a problem for the population as a whole, there are also several potential barriers to healthy food that are more prounced for these groups. Economic barriers include food prices and food insecurity, while physical barriers include the availability of unhealthy food. 

There are numerous opportunities to improve diets including education, improving school meals, reformulating food and restricting portion size and regulating advertising for unhealthy food. Evidence suggests there is no single best approach, but a range of potential strategies that may improve diet.
