The diet of Sumatran orangutans at Perth Zoo was reviewed and altered to simulate more closely foods available in the wild. Diversity of offered plants was increased to over eighty species. Cereal based concentrates were replaced by foods of animal origin, including fish and cheese. Dietary supplements were eliminated. The proportion of different foods was adjusted to meet Dietary Reference Intakes for humans with respect to minerals and vitamins, as recommended by the United States Institute of Medicine.
