текст:There are many problems that British schools are facing today. One of them is making sure that schoolchildren eat healthy food. Gone are the days when children were thrilled with excitement at the thought

of Christmas treats like oranges and tangerines or simple desserts like rice pud ding. Nowadays any fruit and vegetables under the sun can be bought in super markets all the year round. There is only one problem with that-fruit and vege tables that are bought out of season have very little taste. On the contrary, sugar drinks like Coke and numerous varieties of flavoured crisps are full of flavour and chemicals additives! Also, most British mums of today work full time and the last thing they want to do when they get home is cook. Supermarkets are here to

"help"-pre-package and ready-made meals have filled their shelves. As a result, many schoolchildren would rather go hungry than eat fruit or veg etables instead of the more familiar crisps, burgers and chips.

There's nothing wrong with having a can of Coke every now and then but four cans a day is asking for trouble. Did you know that a can of Coke contains about eight teaspoons of sugar and artificial sweeteners? As a result, many modern kids suffer from such illnesses as diabetes, cancer and tooth decay. And, of course, there are more and more children who are extremely overweight.

In Britain, children can either choose to bring their own lunch or buy their

lunch at school. Children from poorer families can have free school dinners but

many of them don't take them for various reasons.
