This is not by any means a peer reviewed journal, most of you cannot even be bothered to use the comments function on the blog. I am not even competent to judge the quality of scientific journals (or I cannot be bothered to look them up. Or something.)
But I can pass on good news, even if they are based on rodent studies and there are many ifs and buts in the summary:
In consequence, moderate beer consumption, due to its content in bioavailability silicon, possibly affording a protective factor for preventing Alzheimer’s disease, could perhaps be taken into account as a component of the dietary habits of the population.
This is from the Food and Chemical Toxicology journal. The article is called Role of beer as a possible protective factor in preventing Alzheimer’s disease and is writtten by the merry trio M.J. González-Muñoz, , A. Peñaa and I. Meseguera of the Pharmacy School, University of Alcalá, Spain.
You will probably have to pay a few thousand dollars to read the whole article. Money you obviously could spend on beer instead.
