Tilbage i 2016 fandt et forskerhold en mulig sammenh\u00e6ng mellem B-vitamin, omega-3 fedtsyrer og udviklingen af demens (I<\/a>).<\/p>\n

Dette er efterh\u00e5nden fulgt op af en del videnskabelige unders\u00f8gelser, som peger p\u00e5 at et indtag af en kombination af B-vitaminer<\/strong> og omega-3 fedtsyrer<\/strong> har en beskyttende effekt i forhold til udvikling af demens.<\/p>\n

Tilsyneladende er der en synergi-effekt af et optimalt indtag af de to. I et studie publiceret i 2022 fandt forskere, at effekten af tilskud af folsyre og B12-vitamin havde en \u00f8get positiv effekt ift. kognitive funktioner hos en gruppe \u00e6ldre, blandt de som havde et h\u00f8jt niveau af DHA (ducosa-hexaensyre) – en langk\u00e6det omega-3 fedtsyre (II<\/a>).<\/p>\n

“Taking into consideration of the literature described above, there is now evidence to suggest that providing nutrient formulas that contain both n-3 PUFA and B vitamins could be efficacious for preserving cognition in the older adults. A possible positive interaction between B vitamins and n-3 PUFA is promising and has largely not been considered in previous human trials. This may be of particular importance when we consider that vitamin B12 inadequacies are common in older adults, and n-3 PUFA status has been demonstrated to be sub-optimal across multiple population groups.” Fairbairn et al 2023, British Journal of Nutrition<\/a>.<\/p><\/blockquote>\n

Synergi-effekten af B-vitaminer, omega-3 fedsyrer og potentielt andre n\u00e6ringsstoffer underst\u00f8ttes af en meta-analyse fra 2023, hvor resultaterne fra 14 kliniske fors\u00f8g blev gennemg\u00e5et (III<\/a>), og konklusionen var at der var en signifikant effekt p\u00e5 mange kognitive m\u00e5leparametre hos \u00e6ldre, der indtog B-vitaminer og omega-3 fedtsyrer.<\/p>\n

Den biologiske forklaring p\u00e5, hvorfor de to komponenter tilsyneladende virker optimalt i samspil er endnu ikke afklaret. Der er dog en sammenh\u00e6ng mellem lavt niveau af B12 vitamin (hvilket kan f\u00f8re til forh\u00f8jet niveau af homocystein) og en h\u00e6mning af oms\u00e6tningen af DHA.<\/p>\n","protected":false},"excerpt":{"rendered":"
