This one is one of the main conclusions of the research work entitled Beer as a dietetic source of silica and its protective effect against aluminum poisoning: Influences on the absorption and accumulation of this neuro-toxic metal , developed by doctors Maria Jose González and Isabel Meseguer, of Pharmacy Faculty of the University of Alcala de Henares .

Meseguer explained that beer is obtained by the maceration of cereals crusts, one of the few silica carrying foods and which reduces the negative effects of aluminum in the organism. She added that aluminum is an oxidation element that affects mainly the brain, due to its reduced capacity for cellular regeneration, 'whereas silica helps to eliminate aluminum that has been found to be in high concentrations in Alzheimer patients'. In particular, aluminum is the second most abundant element in the terrestrial crust and is present in drinking water and foods such as tea, spinach, celery, cucumber and aromatic cooking herbs. It is also used in the food and pharmaceutical industries.

The conclusions of this study, which was recently presented/displayed at the School of Medicine of Cordoba, confirms results obtained by other investigators, in the sense that silica would act as a limiting factor in the absorption of aluminum in the gastrointestinal tract and therefore, diminish the accumulation of this toxic metal in the organism, including the cerebral tissue. The study, unveiled that the moderate-high consumption of beer -with alcohol, that is to say 'between two canes and a liter a day, aid to reduce aluminum levels thanks to its silica content'.

On the other hand, the other director of the study, Dr. María José González, revealed that the next step in the investigation is to propose the possibility of similar results with non/alcoholic beer due to the fact that 'consumption of a daily amount of one litter of beer cannot be a good recommendation'.
