The Amboseli and Masai Mara Baboons
The Masai Mara National Reserve and Amboseli National park are in Eastern Africa. In both reserves,
baboons who live near the tourist facilities steal food waste from the lodge area, while those
whose primary habitat is in the savannah, do not.The refuse is essentially the same food consumed
by humans, with a high fat content.
In studies done among both cohorts of baboons, those who forage in the lodge had two to three times the
levels of insulin, as well as increased total cholesterol, VLDL+LDL and HDL when compared with those animals who eat in the wild and do not forage around the lodges.
