Curcumin – også sundhedsfremmende for din hjerne

Curcumin er bedst kendt for sine betændelses- og kræfthæmmende egenskaber, men nu har forskere også påvist, at gurkemejestoffet også har en sundhedsfremmende indvirkning på hjernen. I både dyreforsøg og kliniske forsøg på mennesker har stoffet vist sig at kunne

• danne nye neuroner i hippocampus
• forbedre præstationen i hukommelsestests
• reducere betændelsestilstande i nerveceller
• beskytte mod tab af hukommelse.

Curcumin er det primære aktive stof i krydderiet gurkemeje. Det er kendt som en substans, der har indvirkning på en lang række lidelser så som diabetes, leddegigt, kræft og kredsløbssygdomme. Men curcumin i sig selv optages dårligt i kroppen. Kun en lille del af den mængde, man indtager, optages i blodet, mens det meste omdannes til andre stoffer eller udskilles af kroppen. Curcumins anvendelse mod hjernelidelser er også påvirket af dets begrænsede evne til at krydse blod/hjerne-barrieren.

Curcumins indvirkning på hjernen

Men nu har forskere fundet en måde at omgå dette problem på. Man har påvist, at indtagelse af curcumin sammen med stoffet galactomannan fra bukkehorn resulterer en mængde af frie curcuminoider i blodet, der er op til 45 gange højere end curcumin alene.

Og dermed kan stoffet komme frem til hippocampus – den del af hjernen, der spiller hovedrollen i indlæring og hukommelse.

Neurodegeneration er betegnelsen for den tiltagende beskadigelse af og funktionstab i nervecellerne, der sker med alderen og ved sygdom. Nogle af de væsentligste mekanismer ved disse sygdomme er

• kronisk inflammation, som kan beskadige hjernecellerne
• iltningsbelastning, som kan føre til celleskader
• ophobning af forkert foldede proteiner, som er skadelige for nervecellerne.

Curcumin kan modgå alle disse problemer, og det betyder, at stoffet har indvirkning på så alvorlige lidelser som Parkinsons, Alzheimers, multipel sklerose og de skader, der opstår efter blodpropper og hjerneblødninger.

Ud over bukkehorn kan også sort peber lette optagelsen af curcumin i kroppen. Prøv Natur-Drogeriets Curcuma Black, som kombinerer disse to krydderier i handy kapsler.
