Young girls are risking iron deficiency and anaemia by not eating correctly, a new report from the Food Standards Agency (FSA) has found.
While finding improvements in much of the nation's dietary habits, the agency's National Diet and Nutrition Survey noted that young women were missing some vital nutrients.
Several papers suggested that the missing areas of nutrition in young women were caused by a backlash to the obesity trend as women desperately tried to lose weight.
The study also found that saturated fat intake is steadily dropping towards the recommended levels, although it remains too high in many people.
Other areas where nutrition was found to be lacking included a poor intake of fibre.
Gill Fine, director of consumer choice and dietary health at the FSA commented: "Good nutrition is important for health and poor diet accounts for a large percentage of premature deaths. We now need to build on the indications of positive change we have observed in this survey.
"By continuing our programme of campaign work and encouraging product reformulation in key areas such as saturated fat, we will hopefully observe further improvements over the next few years of the programme."
