Apes are highly intelligent animals native to sub-Saharan Africa and Southeast Asia. They are closely related to Old World monkeys and humans, with whom they share a similar diet. In the wild, apes eat a variety of plant and animal foods, with the majority of their diet consisting of plant foods such as fruits, leaves, stalks, roots, and seeds. Chimpanzees, for example, are known to eat insects, eggs, and small vertebrates, in addition to vegetation. In captivity, apes may even prefer human food, and it is important to provide them with healthy options.

|---|---|
| Dietary Similarity with Humans | Humans and apes can eat almost identical diets. However, some sources argue that the dietary needs of apes and humans are not very similar due to differences in digestive systems and cooking methods. |
| Food Sources | Apes forage for food in the treetops or on the ground. They may also interact with humans and eat human food in captivity. |
| Food Types | Apes eat a variety of plant and animal foods, with the majority of their diet consisting of plant foods. This includes fruits, berries, leaves, stalks, roots, and seeds, as well as nuts and grass seeds. |
| Specific Foods | Favorite fruits include lychees, mangosteens, mangoes, figs, and durian. They also eat flowers, shoots, insects, eggs, and small vertebrates (birds, reptiles, and mammals). |
| Meat Consumption | While apes are technically omnivores, they are primarily fruit-based vegetarians. Meat consumption is estimated to be between 2-6% of their diet. |

What You'll Learn
Captive apes' preference for human food
Apes and humans share an incredibly similar diet, and in captivity, apes may even prefer human food. While there is no data to directly distinguish this hypothesis, human systems for food perception appear to be generally similar to those in other mammals, including primates. Captive apes have been shown to discriminate finely between levels of sugar, and they tend to prefer their food cooked, which may be due to the higher sugar availability in cooked food.
In a study by Wobber et al. (2008), captive great apes (chimpanzees, bonobos, gorillas, and orangutans) were presented with a choice of either raw or cooked meat. The apes were found to select the cooked samples more often, regardless of neophobic responses to cooked food. These results suggest that the attraction to cooked meat is not unique to humans nor to species that primarily consume meat.
Furthermore, apes in captivity have been observed to prefer "surprise foods" that they have never seen before, and these new foods often become their favorites. For example, the first time they tasted kiwi fruit, it became one of their favorite foods. While it is not common, there have been instances of cannibalism among captive apes.
In terms of dietary needs, humans and apes differ in that humans do not have a cecum, a 4-foot-long organ that monkeys use to digest and ferment fiber into usable nutrition. Humans have evolved to use fire to cook meat, which is how we lost our cecum. Additionally, humans are unique among mammals in their ability to digest lactose as adults due to the persistence of the lactase enzyme.

Chimpanzee diet
Chimpanzees, or chimps, are highly intelligent and live in the forests and savannahs of tropical Africa. They are omnivores, but their diet is predominantly fruit-based. Their diet includes fruits, berries, leaves, seeds, nuts, plants, mushrooms, flowers, insects, meat, and more. They are known to be particularly fond of honey and figs.
Chimpanzees are creative with their tool use and sourcing of food. They use tools to extract insects such as ants and termites from the ground, and they have developed sophisticated ways of accessing honey, such as using sticks to dip into or force open nests. They also use tools to prepare their food, such as forming little balls of fruit called 'wadges' that they dip into water before sucking out the juice, and using stones or branches to break open nuts.
While most of a chimpanzee's diet is plant-based, they do occasionally eat meat. It is estimated that meat and other animal products account for only 3-9% of their diet, with one source stating that it is as low as 2-6%. Chimpanzees were previously believed to be herbivores, but Dr. Jane Goodall observed them hunting smaller mammals such as monkeys and eating them.
In captivity, chimps may eat human food and have even been known to develop a preference for certain human foods. For example, the chimps at the Chimp Haven rescue center are given sugar-free popsicles as a treat, and they are often given "surprise foods" that they have never seen before, which sometimes become their favorites.

Gorilla diet
The diet of gorillas varies across subspecies and seasons. While the diet of the western lowland gorilla (Gorilla gorilla gorilla) is composed of about 67% fruit, 17% leaves, seeds, and stems, and 3% termites and caterpillars, the eastern lowland gorilla (Gorilla beringei graueri) consumes parts of at least 104 plant species. The mountain gorilla (Gorilla beringei beringei), which resides at high altitudes where fruit is scarce, has a diet that is about 86% leaves, shoots, and stems, 7% roots, 3% flowers, 2% fruit, and the remaining 2% ants, snails, and grubs. The diet of the Cross River gorilla (Gorilla gorilla diehli) is less well-studied, but it is known to include fruit, leaves, stems, piths, and some invertebrates.
Gorillas are herbivores and have a large cecum, which helps them digest cellulose. They have huge guts, with a massively important colon, where the fermentation of plant matter occurs. In contrast to humans, who have a small cecum and obtain energy from meat, bone marrow, and other sources, gorillas rely on their digestive system to break down and obtain energy from vegetation. An adult male gorilla can consume over 18 kg (40 lbs) of vegetation per day, including parts of various plant species such as leaves, pith, stalk, or roots. They are selective foragers and do not overexploit an area for food, allowing for quick vegetation replenishment.
Gorillas rarely drink in the wild as they consume succulent vegetation that is composed of almost half water, as well as morning dew. They are also observed using the hair on the back of their hands to absorb water and then sucking it.

Orangutan diet
Orangutans are frugivores, with fruit making up around 60-90% of their diet. They eat more than 400 different plant varieties, including wild figs, mangosteens, mangoes, and durians, the last of which is their favourite. Durians are covered in sharp spines and have a pungent smell, but orangutans use tools and their powerful jaws to break into them. They also eat leaves, shoots, tree bark, honey, insects, bird eggs, and even small vertebrates (birds, lizards, rodents, and slow lorises) on rare occasions.
Orangutans also eat soil and rocks to obtain essential nutrients that are otherwise lacking in their diet. They receive a mixture of sugars and fats from fruit, carbohydrates from leaves, and protein from nuts. They get most of their water from the succulent fruits they eat, but they also drink from rivers and streams, and by licking wet vegetation and the fur on their forelimbs.
Orangutans are capable of memorising the locations of temporary food sources, tracking seasonal changes in fruiting peaks, and identifying behavioural signs from other animals to find fruiting trees. They are known as the "gardeners of the forest" due to their role in seed distribution. As largely fruit-eating animals, they are important propagators of tropical plants, as many fruit seedlings only sprout after passing through an animal's digestive system.
The Sumatran orangutan is more frugivorous and insectivorous than the Bornean orangutan, which eats more inner bark. The Bornean orangutan is native to the island of Borneo and lives in lowland forest areas, particularly in tropical and subtropical rainforests. They are reddish-brown in colour and have large, thick jaws, which they use to crack the skin of nuts and fruits.

Bonobos diet
Bonobos are omnivorous frugivores, meaning they eat a variety of foods but rely heavily on fruit. They are closely related to chimpanzees and are considered the smartest apes in the world. Bonobos primarily eat fruit and vegetation, with fruit making up an estimated 60-90% of their total dietary intake. They are known to eat a variety of fruits, including papaya, mango, sugarcane, figs, and junglesop. They also consume leaves, flowers, seeds, and shoots, which make up about 30% of their diet.
Bonobos gather most of their food from trees, typically at a height of 25 to 40 meters, but they usually climb down to the ground to eat and share their food. They are known to eat the leaves and shoots of sweet potato plants, as well as the pith, or soft tissue found in plant stems. Bonobos have been documented eating over 110 species of plants, with an average of about 10 different plants consumed per day and 40 different ones per month.
In addition to plants and fruits, bonobos also eat invertebrates such as caterpillars, earthworms, beetles, bees, butterflies, and millipedes. They occasionally eat small mammals such as bats, flying squirrels, infant duikers, and young antelopes, but this is very rare. Bonobos are significantly less violent than their chimpanzee cousins, and while they may hunt other mammals, they have only been observed grooming and playing with them.
Bonobos are known to exhibit food-sharing behaviour, which is often associated with genito-genital contact and various social interactions. They are sometimes seen washing their food in water, which is believed to be an evolutionary adaptation for disease avoidance.
Overall, the bonobo's diet is heavily plant-based and fruit-focused, with a variety of other food sources contributing to a smaller portion of their dietary intake.

Frequently asked questions
Apes eat a variety of plant and animal foods, with the majority of their diet being plant-based. This includes fruits, leaves, stalks, roots, and seeds, such as nuts and grass seeds. They also eat insects, eggs, and small vertebrates like birds, reptiles, and mammals.
Fruit is the main source of calories for apes, with their diet consisting of 60-90% fruit.
Apes generally forage for food in the treetops or on the ground. They use three common methods to get their food: terrestrial foraging, which helps them find plants, leaves, and shoots that are edible; hunting; and gathering.
Since humans and apes are closely related, they can eat almost identical diets. In captivity, apes may even prefer human food.
