The staple Tibetan food is barley flour (rtsam-pa), which is consumed daily. Other major foods include wheat flour, yak meat, mutton, and pork. Dairy products such as butter, milk, and cheese are also popular. The people in the higher altitudes generally consume more meat than those of the lower regions, where a variety of vegetables is available. Rice is generally restricted in consumption to the well-to-do families, southern border farmers, and monks.
Two beverages—tea and barley beer (chang)—are particularly noteworthy. Brick tea from China and local Tibetan tea leaves are boiled in soda water. The tea is then strained and poured into a churn, and salt and butter are added before the mixture is churned. The resulting tea is light reddish white and has a thick buttery surface. Chang, which is mildly intoxicating, is thick and white and has a sweet and pungent taste.
