A study published in the Journal of Alzheimer’s Disease in June 2023 shows for the first time [using post-mortem brain samples] brain levels of dietary lutein, zeaxanthin, lycopene, and vitamin E in those with Alzheimer’s disease are half those compared to aged-matched normal brains Although past studies had strongly implicated the possibility that carotenoids may protect the brain against damage contributing to Alzheimer’s disease, there has been no evidence that brain carotenoids correlated with the disease - until now The lead author, Kathleen Dorey stated “This study, for the first time, demonstrates deficits in important dietary antioxidants in Alzheimer’s brains. These results are consistent with large population studies that found risk for Alzheimer’s disease was significantly lower in those who ate diets rich in carotenoids, or had high levels of lutein and zeaxanthin in their blood, or accumulated in their retina as macular pigment,” This new evidence of selective carotenoid and tocopherol deficiencies in the brains of subjects with Alzheimer’s disease adds further support to the growing evidence that a greater dietary intake of carotenoids may slow cognitive decline prior to — and possibly following — a diagnosis with Alzheimer’s disease.
