African bush elephants eat grasses, leaves, twigs, bark, roots, fruits, and flowers, consuming between 149 and 169 kg (330 to 375 pounds) of vegetation every single day. That enormous intake is necessary because their digestive system extracts only about 22 to 45 percent of the nutrients from what they swallow, meaning most of their food passes through largely unprocessed.
Grasses, Leaves, and Woody Plants
As generalist herbivores, African bush elephants eat from a remarkably wide menu. They are classified as mixed feeders, meaning they shift freely between grazing on grasses and browsing on trees and shrubs depending on what’s available. Preferred tree species include marula, camel thorn, and several acacia species, though elephants will sample dozens of plant types across their range. They also eat fruits and flowers when they can find them, and they’re known to be surprisingly selective, sometimes choosing one individual tree over another of the same species based on its nutritional quality.
What they won’t eat is just as telling. In studies tracking their food choices, elephants consistently ignored certain forbs (small flowering plants) even when they were abundant. Their preferences appear driven by nutrient content rather than simple availability, which means they’re actively evaluating their food rather than just eating whatever is closest.
How Their Diet Changes With the Seasons
The wet season and dry season produce dramatically different meals. During summer rains, when savannas are green and lush, elephants eat large amounts of fresh grass and forbs. These foods have high water content and are easy to digest.
As the rains end and grasses dry out, elephants transition to browsing leaves and twigs from woody plants. Later in the dry season, when even leaves have been shed, they shift again to stripping bark and digging up roots. This progression tracks the water content of available food: grasses require the most moisture to grow, leaves need a moderate amount, and bark and roots persist even in drought conditions. Tree bark becomes especially important during these lean months because it contains essential nutrients and sugars while carrying fewer of the bitter defensive compounds that plants produce to deter herbivores.
Bark, Soil, and Mineral Supplements
Elephants don’t just eat plants for calories. They actively seek out specific minerals their diet might lack. Bark stripping is one strategy: the inner bark of certain trees provides vitamins and minerals that grasses alone can’t supply. Elephants can determine the nutritional value of a specific tree by sampling individual parts of it, then decide whether it’s worth stripping further.
When plant matter alone doesn’t meet their mineral needs, elephants create their own salt licks. They use their tusks to dig pits in mineral-rich soil, then eat the dirt. These lick soils are primarily a source of sodium, though they also tend to be higher in calcium, magnesium, and potassium compared to surrounding ground. In Hwange National Park in Zimbabwe, elephants were observed consuming high-sodium soils specifically during the dry season, likely compensating for a sodium shortfall in their plant-based diet. Phosphorus also appears to drive elephant movement patterns year-round, with herds traveling to maximize their intake of this mineral.
Iodine is another nutrient that matters more than you might expect. In South Africa’s Addo Elephant Park, the unusually high reproductive success of the elephant population was linked to iodine-rich borehole water, since iodine plays a direct role in reproduction.
How Elephants Use Their Trunks to Feed
An African elephant’s trunk is essentially a 100,000-muscle tool with two finger-like projections at the tip. These “fingers” allow elephants to pinch small items with remarkable precision, picking up individual seed pods or single leaves. For larger objects, they wrap the trunk around the item and grip it, sometimes using suction to hold food against the underside of the trunk.
Their feeding repertoire is more varied than most people realize. Elephants sweep the ground with the side of their trunk to gather scattered food before picking it up. They grasp branches, then twist and pull to snap them off. When a branch is too long or thick to fit in the mouth, they’ll manipulate it, sometimes wedging it between a tusk and the trunk to break it into smaller pieces. They shake clumps of vegetation to remove dirt or separate edible parts. They bundle loose material by compacting it against the underside of the trunk before lifting it to the mouth. Individual elephants even show side preferences, favoring their left or right when sweeping or grasping, much like human handedness.
Water Requirements
African bush elephants need an average of 70 liters of water per day, used both for drinking and for spraying over their bodies to cool down. Water access shapes nearly every aspect of their movement and habitat use. During the dry season, herds congregate around remaining water sources, and their daily travel routes are structured around reaching water at least once per day. This is one reason elephants can reshape entire landscapes: large herds returning to the same water points and feeding areas create well-worn paths and clear vegetation over wide areas.
Why They Eat So Much
The sheer volume of food elephants consume comes down to their digestive system. As hindgut fermenters, they process food in the cecum and large intestine rather than in a multi-chambered stomach like cattle. This system lets them handle a wide range of plant material, from tender grasses to tough bark, but it’s relatively inefficient. Studies measuring digestive efficiency in African elephants found that they assimilate only about 22 percent of the food’s nutritional value under some conditions, with wild estimates ranging up to 45 percent depending on the quality of forage. Food passes through their system in roughly 21 to 46 hours.
The practical result is that elephants spend 12 to 18 hours a day feeding. They also produce enormous quantities of dung, and because so much plant material passes through only partially digested, elephant dung is packed with seeds and organic matter. This makes elephants critical seed dispersers across the African savanna, spreading viable seeds over vast distances and depositing them in nutrient-rich fertilizer.
