Cereal products, including bread, should make up around a third of your diet; another third should come from fruit and vegetables. Most of the remaining third oshould be made up of milk and dairy foods, meat, fish, eggs, beans and other non-dairy sources of protein, with limited amounts of foods and drinks high in fat and/or sugar.
It’s a good idea to aim to achieve this balance every day, although it is not necessary to achieve it at every meal and you might find it easier to get the balance right over a longer period such as a week.
