The drive to improve the quality of school meals in Scotland has been going down well, according to inspectors.
Hungry for Success was launched in late 2002
Officials who assessed the roll-out of the Hungry for Success programme in 39 schools across Scotland said it was having a "positive impact".
They found children were enjoying healthier choices and larger portions.
However, inspectors said more work needed to be done to ensure the consistent availability of good quality meals in all schools.
Her Majesty's Inspectorate of Education said two "nutrition associate assessors" visited the schools to assess the impact of the executive scheme, which was launched in late 2002.
It outlined maximum salt, sugar and fat contents and the types of food children should be offered.
Primary schools were given until the end of last year to meet the standards and secondary schools have been set a deadline of December 2006.
Senior chief inspector Graham Donaldson said: "In most schools that our inspectors visited, young people are getting more healthy options and are becoming increasingly confident in choosing those options.
"Schools and local authorities are working hard to get children involved in the changes.
"The commitment is making a big difference to what's being served up for lunch across the country."
Mr Donaldson warned against complacency and said the assessors would continue to monitor the standard of meals.
Education Minister Peter Peacock said: "The quality of food on offer has improved and there are more healthy choices than ever.
"Schools and councils are working hard to involve parents and children in the process to develop new healthy eating habits that will last a lifetime.
"But we aren't going to rest on our laurels - this momentum must be maintained to ensure that more and more Scottish young people enjoy the benefits that a healthy lifestyle brings."
