Giant Pandas eat about 40 pounds of bamboo every day in the wild.  They eat really fast and a lot.

Giant Pandas cannot digest fiber, which is necessary for good panda health.   Fiber in the bamboo passes right through them.  That is why they eat so much, they need to eat more to get more nourishment. 

Pandas is the zoo, or in captivity, like to eat bamboo, rice cereal, carrots, apples, and sweet potatoes. 

Pandas have flat teeth in the front of its mouth to chew food and have a few sharp teeth to help bite and tear into the bamboo stalks.   They have 42 teeth in all and very strong jaws for all that chewing.

Pandas need lots of water.  They get most of it from bamboo, which is 90% water,  They also have to drink fresh water from rivers and streams to get enough.

Ninety percent of a Giant Pandas diet is bamboo. Pandas eat 30 species of bamboo. Two of the names are Arrow and Umbrella bamboo. Pandas eat for 12 hours of the day to get enough nourishment. Pandas sometimes wake up just to eat food. Pandas can eat on the ground and in trees. Sometimes they eat other plants.
