The Mediterranean Diet

UPDATE: Earlier post here.

The Mediterranean Diet uses olive oil as the primary fat, so this is interesting:

In an in vitro study, olive oil polyphenols were found to exert bactericidal effects against 8 different strains of Helicobacter pylori (H. pylori). The authors discuss the associations between H. pylori and peptic ulcer disease as well as certain types of gastric cancer. Virgin olive oil, rich in phenolic compounds that have been found to diffuse from the oil into gastric juice and remain stable for several hours in this acidic environment, was found to exert strong bactericidal activity against 8 strains of H. pylori, including 3 antibiotic-resistant strains. The strongest bactericidal effect was exerted by decarboxymethyl ligstroside aglycon (a phenolic compound), at concentrations as low as 1.3 microg/mL – a concentration significantly lower than that found in phenolic compounds from tea, wine, and other plant extracts. The results of this study suggest that virgin olive oil may help to prevent H. pylori-related peptic ulcer disease and gastric cancer. The authors conclude that in vivo studies must be conducted in order to confirm these results.

And also this:

In a prospective study involving 192 community-based individuals diagnosed with Alzheimer’s disease, results indicate that higher adherence to the Mediterranean diet may be associated with a lower risk of mortality. During 4.4 years of follow-up, 85 patients died. An inverse association was observed between adherence to the Mediterranean diet and mortality risk. After adjusting for potential confounders, subjects in the highest tertile for adherence to the Mediterranean diet showed a 73% reduced risk of mortality, compared with subjects in the lowest tertile of adherence. Thus, the results of this study suggest that in patients with Alzheimer’s disease, greater adherence to the Mediterranean diet may lower the risk of mortality.
