When childminders give children snacks and meals, the Early Years Foundation Stage statutory framework requires that they be 'healthy, balanced and nutritious'. It's fairly easy to whip up a meal that fills the criteria because you can balance a meal with fresh vegetables and use fresh ingredients.
If you are providing processed foods such as sausages, ham, nuggets, fishfingers or burgers then check the ingredients and the nutritional breakdown of the foods you are buying. To buy the healthiest options, compare the fat, sugar and salt content. Processed foods are often far more laden with salt and sugar to create flavour than if you were to make the same fare at home. When comparing fat content of products, go for ones with the least saturated fat which is more harmful than unsaturated fat. Better still, try make your own products at home and then you are aware of their contents. You can easily make burgers, fishcakes and breaded chicken or turkey nuggets - slightly time consuming but not difficult.
Try to ration meat to two or three main meals a week, offer vegetarian options (eg. jacket potato and baked beans, mild vegetarian chilli, vegetable lasagne etc.) and fish (fishcakes, jacket potato and tuna, breaded fish etc.) on other occasions.
Processed snacks can also be much less healthy than you might imagine. Snacks are often packaged to make them appear to be healthy but when choosing snacks, again, make sure you compare the fat, sugar and salt content. It's very easy to give children a high salt diet without realising and some healthy looking snacks contain more saturated fat than a packet of crisps! Better still, make snacks yourself. Fruit and vegetables chopped into portions perhaps make the best snacks. Buy yourself a hot air popcorn maker and make fresh popcorn but without the salt or sugar.
Providing healthy, balanced and nutritious food isn't difficult but it can be deceptive if you are offering factory processed foods. Check the food labels and know what you are feeding your little ones.
