It seems school children all over the world complain about their school food．Cherie Blair，the wife of former British Prime Minister Tony Blair，said that she would prepare a packed lunch for her son if school dinners do not improve．So what do students of your age eat for lunch at school？
Japan
High schools have canteens（餐廳），which serve everything from noodles to rice，but not burgers and chips．Other children bring food from home such as cold rice balls，meat or fish，pickles（泡菜） and vegetables．
Students take home a menu for the coming month containing notes on nutrition value．Twice a year parents are invited to have a taste of the food．The class with the fewest leftovers（剩飯） at the end of the month receives a prize．
United States
A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken，lettuce and pickles，fruit and cookies．School lunches must also provide at least one-third of the daily dietary allowances（定量） of protein，vitamin A，vitamin C，iron，calcium and calories．
Australia
Meat pies，sausage rolls and hot dogs are all traditional dishes in Australian school shops．But as the nation pays more attention to children's health，healthier foods have started to find their way onto school menus．
Many schools have used a traffic light system．The sale of red-labelled（標簽） foods，including pastries，chocolate and soft drinks，is served only twice a week．Healthier green-labelled foods such as sushi，sandwiches，corn and watermelon，however，are available every day．
In some schools，students have a choice of up to 89 foods to choose from，including popcorn and rice．
South Africa
Most of South Africa's schools do not serve meals at all．Classes end at 1：30 p．m．a(chǎn)nd students get their own lunches．Many students bring food from home，usually sandwiches．
Fast food and fried food sell the best among students，which has led to a rise in obesity among children．But as more people began to realize the fact that being too fat may cause different diseases，some schools in towns have led the way towards better nutrition（營養(yǎng)）．Now students at these schools are provided with lunches of porridge（粥） with vegetables，such as cabbages，onions，beans，carrots and tomatoes．
