Although bamboo is the favorite food of the giant pandas, the animals can use only a fraction of it at all. The majority of the food they excrete undigested again. Because the gut of the panda is like the digestive tract of a carnivore. In order for the bamboo lovers to have enough energy to survive, they not only eat tons, but move a little and sleep a lot. Their daily energy consumption is only 38 percent compared to similarly sized land mammals. Why the bear can live despite vegetarian diet: A gene mutation ensures that the panda releases much less thyroid hormones than comparable mammals. Chinese researchers have recently discovered this.
