Twice daily oral administration of Palmaria palmata protein hydrolysate reduces food intake in streptozotocin induced diabetic mice, improving glycaemic control and lipid profiles

Abstract This study investigated the antihyperglycaemic effectiveness of an oral Palmaria palmata protein hydrolysate (PPPH), versus metformin, upon metabolic control in streptozotocin (STZ)-induced diabetic mice. Mice were administered PPPH (50 mg/kg bodyweight) or metformin (200 mg/kg bodyweight) by oral gavage twice-daily for 18 days. Blood glucose and plasma insulin were measured every third day. PPPH caused a significant reduction in blood glucose (p
