Milton Keynes North MP Mark Lancaster supported National School Meals Week with lunch at a city school.
Running from November 4-8, the week aimed to raise awareness of school meals and saw each child being provided with a meal.
Mr Lancaster visited Greenleys Junior School where he sat and enjoyed a healthy meal of sausages and mash with the children.
He said: “Too often we are feeding our children food high in sugar and fat and we are damaging their health.
“It is vital we ensure they have a healthy, balanced diet and I was pleased to join in at Greenleys Junior School.”
