That’s because it eats a lot and has low calories. If it eats a lot, it will make you fat.

Giant pandas’ diet includes 63 types of bamboo. These bamboos are mainly divided into two families, one is the ce (ce, four tones) bamboo superfamily with 19 species, and the other is the North American arrow bamboo superfamily with 44 species, half of which are endemic to my country. The giant panda's habitat is about 200,000 square kilometers, in which mainly coniferous and broad-leaved forests grow. The mountains are crisscrossed with alternating mountains and rivers, and the temperature is relatively low, so bamboos are mostly cold-temperature.

Although giant pandas like to eat bamboo, they do not have no choice. They will choose different bamboo species and different bamboo parts to eat. Since bamboo is a low-nutrient, high-fiber food, it can be difficult to choose the right one to eat. The main fiber substances in bamboo are cellulose, hemicellulose and lignin. Hemicellulose is relatively easy to digest, while cellulose and lignin are not. Some giant pandas will choose parts with lower cellulose and lignin content, such as bamboo shoots and freshly grown bamboo leaves. Other pandas will choose bamboo that can be excreted quickly, so that they can eat more and be more nutritious.

Like humans, giant pandas also like to eat bamboo shoots, but not very much the stems and old leaves of bamboo. But since there are bamboo shoots only in summer, giant pandas mainly eat bamboo leaves and bamboo stems throughout the year. When there are bamboo shoots, the giant panda will eat them vigorously, 20 hours a day, and 40 kilograms! Even if you only eat bamboo leaves, you will eat about 15 kilograms. Bamboo shoots are so delicious and easy to digest. But the bamboo shoots still have a layer of skin, so the panda has to peel off the skin and eat only the core.

Eating methods

Giant pandas spend nearly half of their time eating every day. The digestive tract of the giant panda retains the characteristics of its ancestors and is similar to that of carnivores, such as a relatively short digestive tract, sharp canine teeth, a single-chambered stomach, the absence of a cecum, relatively sharp claws and well-developed meat pads. In the process of slow evolution, it gradually evolved to eat high-fiber bamboo as its main food, and evolved some structural features to adapt to living on bamboo, such as the masseter muscle, the tooth crown and the tooth process, and the front paws evolved to have five toes. A dummy thumb is formed to form a dual grip structure to facilitate holding bamboo.

Giant pandas spend most of their time on their hands and knees collecting, preparing and eating food. They don't care where they are - sitting, lying down, leaning on their sides - they just keep peeling off bamboo stalks and eating bamboo leaves. 99% of the giant panda's food is bamboo, and sometimes it may be some wild flowers, vines, weeds, honey, and even some meat.

Giant pandas eat bamboo as their staple food and also like to drink water. Most giant pandas’ homes are located near streams and streams, so they can drink from clear springs nearby. Giant pandas drink water at least once a day. Although there is abundant food in some places, it is difficult to find giant pandas without water. In winter, when the mountain water is frozen by ice, some giant pandas may also be nostalgic for the hidden conditions and food base of their homeland and may even travel long distances, down ditches, to drink water in the valley, and then return home.

Giant pandas always seek water near and far away, and follow an obvious drinking path day after day. When they come to the stream, they drink by licking and sucking. If the stream is thinly iced or filled with gravel, they break the ice with their forepaws or dig a shallow pit of about 25 x 20 meters with their claws to lick and drink. Giant pandas take bamboo as their main food, but bamboo is difficult to digest and absorb. As a result, the giant panda's energy intake is greatly restricted, and all its activities must take into account taking in as much energy as possible and consuming as little energy as possible. ?

With changes in climate and food distribution, giant pandas have the habit of vertical migration. In summer, they move up high mountains to hunt for bamboo shoots, and in autumn and winter, snow-covered mountains move down to mid- and low-mountain areas. ?

Giant pandas have a low digestion and utilization rate of bamboo, and the food stays in the body for a short time. Therefore, they eat a large amount and excrete it quickly to obtain enough energy to meet their needs. Depending on the parts of bamboo that giant pandas eat in different seasons, their daily food intake is roughly as follows: 23-40 kilograms of bamboo shoots; 10-18 kilograms of bamboo leaves; and 17 kilograms of bamboo stalks. Giant pandas are very intelligent animals, which is reflected in their excellent feeding strategies. They not only select the bamboo species with the best nutritional value in the region, but also give priority to the parts with the highest nutritional value. The order of eating is bamboo shoots, young bamboo, and bamboo stalks.
