Alzheimer’s, dementia and memory loss

(see also below under Degenerative diseases)

In Alzheimer’s research there is some indication that the effect of antioxidants “may reduce the amyloid plaque deposition in the neuronal cells” (128). Seagreens® are an ideal whole food source of all the antioxidant nutrients and can be readily included in a liquid or solid diet at significant levels of daily intake for very long periods.

Seagreens® is also a natural source of vitamin B3 (nicotinamide) found in meat, fish beans, cereals and potatoes which may help protect the brain and boost memory in healthy people. US research has shown the vitamin reduces the level of a protein (phosphorylated tau) known to be involved in abnormal ‘deposits’ in brain cells called ‘tangles’ which contribute to brain conditions associated with Alzheimer’s (202). NB. The Alzheimer’s Research Trust issued a warning that people should not use formulated B3 supplements until human research has been completed.

Vitamin B12 deficiency has also been linked to dementia and declining memory in old age, according to an Oxford, England study in 2008 (213). Brain shrinkage was greatest among adults with the lowest levels of B12 aged between 61 and 87, even though above the level defined as a vitamin deficiency. B12 is present is Seagreens® in a natural food form that is bioavailable to humans (91, and for details see below under Vegan and vegetarian diets).

High doses of formulated multivitamin and mineral supplements are not natural foods and may cause nutritional imbalances especially in the elderly.
