New WHO Guidelines on risk reduction of cognitive decline and dementia

Relevant to concerns about FSANZ Standard 2.6.5 which has allowed products such as Souvanaid® and Ceretain® to be self-assessed and promoted for the dietary management of Alzheimer’s dementia or related mild cognitive impairment.

On supplements, WHO says: Vitamins B and E, polyunsaturated fatty acids and multi-complex supplementation should not be recommended to reduce the risk of cognitive decline and/or dementia. Quality of evidence: moderate. Strength of the recommendation: strong.

As reported by CBS News: Eating well, and possibly following a Mediterranean-style diet, may help prevent dementia, the guidelines say. But they take a firm stance against vitamin B or E pills, fish oil or multi-complex supplements that are promoted for brain health because there’s strong research showing they don’t work.

“There is currently no evidence to show that taking these supplements actually reduces the risk of cognitive decline and dementia, and in fact, we know that in high doses these can be harmful,” said the WHO’s Dr. Neerja Chowdhary. “People should be looking for these nutrients through food … not through supplements”. Maria Carrillo, chief science officer of the Alzheimer’s Association, agreed.
