Chronic ‘Butter Flavoring’ Exposure Linked to Harmful Brain Process

MONDAY, Aug. 6 (HealthDay News) – Chronic exposure to an artificial butter flavoring ingredient, known as diacetyl, may worsen the harmful effects of a protein in the brain linked to Alzheimer’s disease, according to a new study.

The findings should serve as a red flag for factory workers with significant exposure to the food-flavoring ingredient, researchers from the University of Minnesota said in the report published in a recent issue of the journal Chemical Research in Toxicology.

Diacetyl is used to give a buttery taste and aroma to common food items such as margarines, snack foods, candy, baked goods, pet foods and other products.

The investigators pointed out that previous studies have already linked diacetyl to respiratory and other health problems among workers at microwave popcorn and food-flavoring plants.

Although diacetyl forms naturally in fermented beverages, such as beer and wine, its chemical structure is similar to a substance that makes beta-amyloid proteins clump together in the brain. This clumping, the study authors noted, is a hallmark of Alzheimer’s disease.

In their study, the researchers found that diacetyl also increases the amount of beta-amyloid clumping in the brain. And it worsened the beta-amyloid protein’s harmful effects on nerve cells grown in a lab when the cells were exposed to the same levels of diacetyl that factory workers might be exposed to in their jobs.

The study authors pointed out that other experiments revealed that diacetyl also crosses the “blood-brain barrier,” which helps protect the brain from dangerous substances. Diacetyl also prevented a beneficial protein from protecting nerve cells.

“In light of the chronic exposure of industry workers to diacetyl, this study raises the troubling possibility of long-term neurological toxicity mediated by diacetyl,” Robert Vince and colleagues concluded in a news release from the American Chemical Society.

The study was funded by the Center for Drug Design research endowment funds at the University of Minnesota.

While the study found an association between chronic diacetyl exposure and certain brain protein processes, it did not prove a cause-and-effect relationship.

You’re never going to come close to that drinking beer

Too much of anything is gonna do something harmful.

I read an article the other day that said light aerobic activity (walking and jogging) will actually help grow the part of the brain that controls motor function and memory. This is the part that slowly dies with Alzheimer’s patients. People who walk and jog regularly had 2-3% growth in this area compared to people who work out but mainly lift weights and people who don’t exercise at all.

So, keep drinking beer… just make sure to walk or jog to your kegerator as much as possible! And always to a d-rest!

:cheers:

Yeah, I bet the alcohol will get you way before the diacetyl has a chance. :o

More nonsensical scare mongering by the media.
While it has been determined that exposure to the diacetyl can be harmful, it is so mainly through inhalation.

If you can resist snorting your beer, you probably have no worries!

So much for the aroma side of beer judging… :lol:

Gawd, I need a drink. :roll:
