🦧🍎 A balanced diet keeps orangutans like Kyle healthy! The fruits that orangutans encounter in the wild are more fibrous and have different nutrients and sugars than those in the United States. Our primate team works closely with the Zoo’s Department of Nutrition Sciences to evaluate our orangutans’ diets and make adjustments based on their caloric needs. . . #OrangutanCaringWeek | Smithsonian’s National Zoo and Conservation Biology Institute
