New Study Shows Chemical In Beer Prevents Alzheimer’s And Parkinson’s

A new study conducted in China suggests that “beer is good for the brain.” According to to an article in the Inquisitr, here’s why. “The beer draws its superpowers from hops, the female flowers of the hop plant Humulus lupulus, which are used primarily as a flavoring and stability agent in beer. However, apart from contributing to the signature taste of the beer, hops releases a chemical — Xanthohumol — that has the potential to fight off neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease.” These findings come from a journal article, with the decidedly unsexy title Xanthohumol, a Polyphenol Chalcone Present in Hops, Activating Nrf2 Enzymes To Confer Protection against Oxidative Damage in PC12 Cells, which was published in the Journal of Agricultural and Food Chemistry, published by the American Chemical Society.

Here’s the abstract:

Xanthohumol (2′,4′,4-trihydroxy-6′-methoxy-3′-prenylchalcone, Xn), a polyphenol chalcone from hops (Humulus lupulus), has received increasing attention due to its multiple pharmacological activities. As an active component in beers, its presence has been suggested to be linked to the epidemiological observation of the beneficial effect of regular beer drinking. In this work, we synthesized Xn with a total yield of 5.0% in seven steps and studied its neuroprotective function against oxidative-stress-induced neuronal cell damage in the neuronlike rat pheochromocytoma cell line PC12. Xn displays moderate free-radical-scavenging capacity in vitro. More importantly, pretreatment of PC12 cells with Xn at submicromolar concentrations significantly upregulates a panel of phase II cytoprotective genes as well as the corresponding gene products, such as glutathione, heme oxygenase, NAD(P)H:quinone oxidoreductase, thioredoxin, and thioredoxin reductase. A mechanistic study indicates that the α,β-unsaturated ketone structure in Xn and activation of the transcription factor Nrf2 are key determinants for the cytoprotection of Xn. Targeting the Nrf2 by Xn discloses a previously unrecognized mechanism underlying the biological action of Xn. Our results demonstrate that Xn is a novel small-molecule activator of Nrf2 in neuronal cells and suggest that Xn might be a potential candidate for the prevention of neurodegenerative disorders.

This is not the first time such findings have been studied, so this appears to be yet another confirmation in the growing body of positive health benefits of moderate beer drinking. What the team of Chinese scientists found was a “previously unrecognized mechanism underlying the biological action of Xn,” suggesting Xanthohumol “might be a potential candidate for the prevention of neurodegenerative disorders.”

The Inquisitr concludes:

Hops have been used in Chinese medicine for centuries. However, its efficacy to prevent Alzheimer’s and Parkinson’s was discovered only recently. Neuronal cells — which are in the brain, spine, and nerves — are in limited supply over one’s lifetime. These cells are especially susceptible to stress. This stress is thought to be one of the ways brain-related disorders such as Alzheimer’s and Parkinson’s begin.

Beer, as I probably don’t need to remind you, is at least one great way to relieve stress.
