Cur­cumin, the nat­u­ral pig­ment that gives the spice turmeric its bright yel­low color, is the fo­cus of a num­ber of re­cent sci­en­tific stud­ies sug­gest­ing a broad range of health benefits, in­clud­ing po­ten­tial pro­tec­tion against cer­tain can­cers, heart fail­ure, di­a­betes, Alzheimer’s, and arthri­tis. M. Belvi­ranlı, from Sel­cuk Univer­sity (Turkey), and col­leagues ad­min­is­tered cur­cumin or a con­trol com­pound (corn oil), for seven days, and a fur­ther five days dur­ing which they were tested us­ing a wa­ter maze. The re­searchers ob­served that cur­cumin sup­ple­men­ta­tion de­creased the time needed to com­plete the wa­ter maze, and de­crease the to­tal dis­tance trav­eled dur­ing the test. These study au­thors re­port that: “It may be con­cluded that, cur­cumin sup­ple­men­ta­tion im­proves cog­ni­tive func­tions by de­creas­ing the lipid per­ox­i­da­tion in brain tis­sue of aged fe­male rats.” Sep­a­rately, BS Fleenor, from Univer­sity of Colorado (Colorado, USA), and col­leagues sup­ple­mented the chow of aged mice with 0.2% cur­cumin, find­ing that the com­pound ame­lio­rated large elas­tic ar­ter­ies stiff­en­ing, ni­tric ox­ide­me­di­ated vas­cu­lar en­dothe­lial dys­func­tion, and ox­ida­tive stress. The study au­thors con­clude that: “Cur­cumin may be a novel ther­apy for treat­ing ar­te­rial ag­ing in hu­mans.” Ref­er­ences: Belvi­ranlı M, Oku­dan N, Atalık KE, Oz M. “Cur­cumin im­proves spa­tial mem­ory and de­creases ox­ida­tive dam­age in aged fe­male rats.” Pick Biogeron­tol­ogy. 2013 Apr;14(2):187­96.
