Kids in two parts of England will be able to get free school meals as part of a trial to see if it helps them get healthier and do better in class.
Primary school pupils in County Durham and Newham, North London, will get the free food in a £40m, two-year trial.
If the test is successful, kids all over England could be given access to free school dinners.
In Scotland, all pupils aged between five and seven will be getting free school lunches from next August.
And in English secondary schools, new rules are coming in about how healthy school food has to be.
They give limits on the levels of things like fat, sugar and vitamins in food served in schools.
There are different rules governing school food in different parts of the UK.
