French elementary school students don't go to school on Wednesdays, so that's why there are only four meals!
Almost all foods are prepared right in the kitchen; they’re not ready-made frozen. This means mashed potatoes, most desserts, salads, soups, and certainly the main dishes are prepared daily. Treats are included — the occasional slice of tarte, a dollop of ice cream, a delicacy from the local pastry shop.
What about exercise?
What the French specialize in is moving all the time, not just during a bi-weekly gym class. For example, elementary-aged students throughout the country have three set recess periods during the day: a 15-minute run-around in the morning, a 60-minute recess after lunch, and another 15-minute break in the afternoon.
On top of these designated times, children are encouraged to walk and bike to school, although this depends largely on the proximity of home to school. Bicycle parking spaces are usually all used up in the morning at our local school, and while younger students ride to school next to an adult, the older 5th graders often cycle on their own.
