Among the individuals with insufficient amounts of folate, the rates of dementia were 3.4%. The rates of death from any cause came in just under 8%.
The participants without the deficiency experienced rates of dementia of 3.2%, and the all-cause death rates amounted to almost 4%.
After factoring in co-occurring conditions, such as diabetes, vitamin B12 deficiency, cognitive decline, and depression, the researchers associated folate deficiency with a 68% higher risk of a dementia diagnosis.
Did you know? Out of all plant-based foods, lentils contain the most folate!
Lentils are an excellent source of folate. A type of B-vitamin, folate helps support red blood cell formation and proper nerve functions. Folate also plays an important role in lowering artery-damaging homocysteine. In addition, the water-soluble vitamin may help prevent anemia and protect against developing heart disease, cancer, and dementia. Folate is particularly important for women of childbearing age, as it is needed to support increasing maternal blood volume.
I also should note that my brothers raise lentils on the farm and I frequently transport 50 and 100 pound bags of lentils to the Seattle area for sale (and donation to a food bank) at near my own cost.
