Explanation: i had this question before
Over a long period of time (> 0.5 Ma), boisei had a diet predominantly composed of C4 resources, most likely grasses or sedges (Turkana, Baringo, Natron, and Olduvai regions).
Massive and low-cusped postcanine teeth, thick and large mandibular corpora, and strong masticatory muscles are all characteristics of the East African hominid Paranthropus boisei that are usually thought to be adaptations for a diet of nuts, seeds, and hard fruit.
This hypothesis was based on analyses of the morphology of P. boisei, but it also received indirect support from dental microwear studies of P. robustus, a close relative. These studies found that the South African Paranthropus had molar wear consistent with it having ingested and chewed small, hard food items, if not as primary resources then at least as backup foods.
