Nu lyder titlen meget alvorlig, men den skal ikke helt tages for p\u00e5lydende.<\/p>\n
Konklusionen er ellers interessant nok: hos s\u00e6rligt f\u00f8lsomme mus \u00f8ges tumorv\u00e6ksten i tyndtarmen hvis de lever p\u00e5 en ketogen di\u00e6t sammenlignet med kontrolmus.<\/p>\n
Men som jeg n\u00e6vnte ovenfor er der flere ting, der skal tages h\u00f8jde for:<\/p>\n
– Fors\u00f8gene er udf\u00f8rt p\u00e5 mus.<\/p>\n
– Musene er genetisk manipulerede til spontant at danne tumorer i tyndtarmen med stor hyppighed.<\/p>\n
– Musenes kost afspejler ikke en kostplan, som mennesker p\u00e5 en ketogen di\u00e6t ville f\u00f8lge.<\/p>\n
– Hos mennesker er tyndtarmskr\u00e6ft meget mindre hyppig end tyktarmskr\u00e6ft.<\/p><\/blockquote>\n
Forskernes konklusion er, at ketoner i sig selv ikke spiller en rolle for kr\u00e6ftudviklingen, men at det derimod er oxidationen af kostens fedtsyrer, der kan fremme tumordannelse – en p\u00e5virkning af stofskiftet af initierede stamceller i tarmepithelet.<\/p>\n
Hvor meget disse resultater betyder for hvordan man skal opfatte en ketogen di\u00e6t i forhold til risikoen for at udvikle tarmkr\u00e6ft er et godt sp\u00f8rgsm\u00e5l. For personer, som har den arvelige lidelse famili\u00e6r adenomat\u00f8s polypose (FAP, eng: familial adenomatous polyposis) kan det dog v\u00e6re relevant information. Disse personer har en kraftigt forh\u00f8jet tendens til at danne polypper i tarmen, og og udover en forh\u00f8jet risiko for at udvikle tyk- og endetarmskr\u00e6ft er der ogs\u00e5 en \u00f8get risiko for at udvikle kr\u00e6ft i tyndtarmen.<\/p>\n
Der er ogs\u00e5 epidemiologiske data, der peger i retning af, at indtagelse af store m\u00e6ngder m\u00e6ttet fedt kan \u00f8ge risikoen for tarmkr\u00e6ft, men risikoen er ikke tydeligt adskilt fra indtagelse af forarbejdet og r\u00f8dt k\u00f8d.<\/p>\n
S\u00e5 igen, resultaterne fra studiet skal tages med et stort gran salt, hvis man vil overf\u00f8re det til mennesker \u2013 ikke mindst, hvis den ketogene kostplan er varieret.<\/p>\n","protected":false},"excerpt":{"rendered":"
