Industry funded study of the week: eggs and Alzheimer’s

I learned about this one from a British public relations firm.

Hey Marion,

Eating an egg a day could cut Alzheimer’s risk by 27%, major new study reveals as UK searches for dementia prevention hit a five-year high.

The press release linked to the study

Egg Intake and the Incidence of Alzheimer’s Disease in the Adventist Health Study-2 Cohort Linked with Medicare Data, followed nearly 40,000 American adults aged 65 and over for an average of 15.3 years — making it one of the largest investigations to date into how diet affects dementia risk.  Compared with people who never ate eggs, the researchers found:

– 5+ eggs per week — 27% lower Alzheimer’s risk

– 2-4 eggs per week — 20% lower risk

– 1-3 eggs per month — 17% lower risk

Why eggs?

Researchers say the protective effect comes from the unique cocktail of brain-essential nutrients found in eggs. The standout is choline — used by the body to produce acetylcholine, a brain chemical critical for memory and learning. Eggs are also rich in lutein, tryptophan, and the omega-3 fat DHA.

Lest I forget that this is about public relations, the message ends with this:

Comment

Guess who paid for this study:

Funding: Initial support for the cohort was provided by the National Cancer Institute (grant 1U01CA152939). The analyses in this study were supported by an investigator-initiated grant from the American Egg Board. The funding sources had no role in the study design, execution, data analysis, interpretation, manuscript preparation, or publication.

Conflict of interest: The authors report no conflicts of interest.

Adventists are generally healthier than the general population, so it’s hard to know what to make of this.  Dietary advice in the U.S. even at the height of concerns about cholesterol always said one egg a day is OK.  This study does not change that.

Will eating eggs help you prevent Alzheimer’s?  If only it were that easy.

And again: the authors do not believe that requesting a grant from the American Egg Board constitutes a conflict of interest.  I do.  The egg industry has a vested interest in the outcome of this study, and got the result it wanted.
