The document lists seven things not to do after a meal for better digestion. These include smoking, eating fruits, drinking tea, loosening one's belt, bathing, walking, and sleeping immediately after a meal. Smoking after a meal is said to be equivalent to smoking ten cigarettes in terms of cancer risk. Drinking tea contains acids that can harden proteins and make digestion difficult.
