Is is the last thursday before the Lent which means we celebrate today Fat Thursday!
The tradition of Fat Thursday is very old, even older than the donuts themselves! In the Middle Ages, when they were not yet known in Poland, people were eating pork fat, bacon and fat meats and drinking heavily. The tradition of eating donuts started in XVI century. The supersticion sais that who doesn't eat a donut on Fat Thursday will have bad luck.
In average each Pole eats 2,5 donuts and in total the Polish eat 100 million of donuts that day. An average donut has 200 kcal.
Have a sweet day!:)
