In September 2018 researchers from Iran published their review of the medical scientific literature to assess the association between dietary fat intake, saturated fatty acids, monounsaturated fatty acids and the risk of fracture. A total of 6 studies were included in the review. Results showed no significant association between total dietary fat intake and risk of fracture. However, an increase in saturated fatty acids intake was significantly associated with an increased risk of hip fracture. In addition, an increased intake of monounsaturated fatty acids derived from animal sources was significantly associated with the risk of fracture.
