Chinese workers on the railroad were fed a Chinese diet including dried oysters, dried fish, sweet rice, crackers, dried bamboo, salted cabbage, Chinese sugar, dried fruits and vegetables, dried seaweed, Chinese bacon, dried mushrooms, peanut oil, tea, rice, pork, and chicken.  This was a much healthier diet than the beef, beans, bread, butter and potatoes of white workers at the time.  The Chinese also drank barrels of hot tea.   White workers, instead, would drink cold water.  Too often this water was contaminated and caused illness among the workers.
