The impact of orthorexia nervosa on bone health
The impact of orthorexia nervosa on bone health

Summary/Abstract: Dietary recommendations are meant to optimize bone health and prevent bone resorption and osteoporosis when dietary intakes do not maintain normal serum levels of calcium, phosphorus, and magnesium. The current healthy eating trend is verified in association with its effects on bone density, with particular attention to some practices: vegetarianism, lactose-free diet, alkaline diet and dietary supplements. A plant-based diet may inhibit intestinal calcium absorption, due to the impact of oxalates and phytates. Lactose was suggested to enhance calcium absorption and lactose intolerant individuals have a lower calcium intake than healthy controls. The alkaline diet, with foods associated with neutral or alkaline urine thought to be beneficial for the skeleton, is based solely on findings from patients with renal impairment, where alkaline salts, such as calcium phosphates, are released from bones in order to provide an optimal acid-base balance. Excessive vitamin and mineral consumption limits the absorption efficiency and induce detrimental structural changes in bone morphology .A healthy diet with protective effects on bone should be focused on diversification, instead of restrictions and excess.
