More than half of British children don't eat a single portion of vegetables a day, according to Newsround's food survey. The Government recommends that everyone should have at least five portions of fruit and veg a day. But the survey shows 52 in every 100 children don't have any veg, and 44 in 100 have no fruit on a daily basis. What we're eating is a big issue at the moment because one in three children in the UK is obese or overweight. That figure has trebled in the last 25 years. The survey was of 1,432 boys and girls, aged 7 to 12, across England, Scotland, Wales and Northern Ireland. It also showed that lots of children are trying to make positive changes to their diet. It suggested that eight in 10 children have made changes like drinking more water and eating more fruit and vegetables recently.
