Vitamin โขB12 Levels May Beโ Key โขto Slowing cognitive decline, โNew Research Suggests
BOSTON – Emerging research indicates thatโ maintainingโ adequate vitamin B12โค levelsโข could play โฃa notable role in preventing cognitive decline and potentially mitigating the effects of Alzheimer’s disease. โฃA โ2015 study published in Alzheimers & Dementia,conducted by scientists at Boston University Medical Center,foundโ that nearly 2,000 participants with an โaverage age of โฃ60 who had higher vitamin B12 levelsโฃ experienced slower rates of cognitive decline,specifically in languageโ skills,compared to those with lower levels. Researchers โconcluded that increasedโ vitamin B12 could help โ”mitigate cognitive decline in later life.”
Though, a more recent study challenges โcurrent โrecommendedโค daily allowances of the vitamin. โResearchers found evidence of brainโฃ damage in participants even when consuming vitamin B12โ at levels considered generally sufficient.Dr. Ari J. โฃGreen, lead author of theโฃ study, explained that previously defined “healthy” levels of B12 may not detect subtle functional issues affecting individuals without obvious symptoms. He also โคnoted that a severe B12 deficiency โฃis often linked to anemia and โคpotential long-term brain damage โdue to iron deficiency.
The โขGerman โSociety โfor Nutritionโ (DGE) currently recommends โฃa dailyโ intake of at least 4.0 micrograms of vitamin B12. Because vitaminโ B12 is primarily found in animal products, vegans โand vegetarians are advised to be notablyโข vigilantโ about theirโฃ intake, potentiallyโฃ exploring sources like sauerkraut,โข seaweed (nori), and shiitake mushrooms, or consulting a doctor about โฃsupplementation.
for those who consume animal products, theโค following amounts of vitamin โฃB12 are typically found in:
* 1 egg: approximately 1 microgram
* 1 โคglass of milk (200 ml): approx. 0.9 micrograms
* 1 slice of Gouda โ(30 g): approximatelyโข 0.8 micrograms
* โข 1โค portion of โคsalmonโ on bread โข(50โ g):โฃ 2โข toโข 3โข micrograms
