Elevated intraocular eye pressure is the principal diagnostic risk factor for glaucoma. People with diabetes have an increased risk of glaucoma, suggesting that this eye disease is influenced by elevated glucose and insulin levels. Adopting a low-glycemic hunter-gatherer Paleolithic diet, as well as taking insulin-sensitizing dietary supplements, can reduce weight and improve glucose tolerance. It is reasonable to assume that such dietary changes may also lower intraocular eye pressure.
