Olive Oil - Stomach Ulcers (H. pylori) & Cancer - Blood Pressure
Thanks to Leo, for sending this. I have been advocating Olive Oil, the rich unprocessed dark variety, for ulcers and general health for years. Here is support for those who still doubt the wisdom of this old remedy.....
Abstract:
Helicobacter pylori is linked to a majority of peptic ulcers and to some types of gastric cancer, and resistance of the microorganism to antibiotic treatment is now found worldwide. Virgin olive oil is an unrefined vegetable oil that contains a significant amount of phenolic compounds. Under simulated conditions, we have demonstrated that these substances can diffuse from the oil into the gastric juice and be stable for hours in this acidic environment. In vitro, they exerted a strong bactericidal activity against eight strains of H. pylori, three of them resistant to some antibiotics. Among the phenolic compounds, the dialdehydic form of decarboxymethyl ligstroside aglycon showed the strongest bactericidal effect at a concentration as low as 1.3 g/mL. Although the experimental conditions are different from other reported works, this bactericidal concentration is much lower than those found for phenolic compounds from tea, wine, and plant extracts. These results open the possibility of considering virgin olive oil a chemopreventive agent for peptic ulcer or gastric cancer, but this bioactivity should be confirmed in vivo in the future.

"In vitro activity of olive oil polyphenols against Helicobacter pylori"
Authors: C. Romero, E. Medina, J. Vargas, M. Brenes, A. de CastroWe evaluated the effects of a moderate consumption of olive oil on lipid profile, BMI, and blood pressure (BP) in a group of 160 healthy men from non-Mediterranean regions [Northern Europe (n = 50; Finland and Denmark) and Central Europe (n = 60; Germany)] and Mediterranean regions [Southern Europe (n = 45; Italy and Spain)]. The study was a randomized, cross-over trial with 3 intervention periods of 3 wk and 2 wash-out periods of 2 wk. At the intervention periods, 3 similar olive oils (25 mL/d), differing only in their phenolic concentration, were administered to the healthy volunteers. Plasma oleic acid levels increased 2–3% (P < 0.05) in men from populations with lower habitual olive oil intakes (Northern and Central Europe). General linear models showed that the administration of the sequence of the 3 olive oils was responsible for a 3% decrease in systolic BP (SBP) (P < 0.05), but not in diastolic BP, in the non-Mediterranean subjects. Multivariate analysis indicated that the lipid profile did not change in either Mediterranean or non-Mediterranean men due to the olive oil intervention. The results of this study suggest that a moderate consumption of olive oil may be used as an effective tool to reduce SBP of healthy men who do not typically consume a Mediterranean diet. However, additional longer trials are necessary for confirmation.

From: moderator@gordonresearch.comWe all need to realize that Olive Oil and Vinegar is the health promoting salad dressing.
The Vinegar is an acetic acid for a chelation effect and also by acidifying the stomach contents, like wine, it improves digestion since Hypochlorhydria is epidemic in today's toxic and rushed world.
Here you learn that Olive Oil has many benefits we had not appreciated until now. Splurge on yourself and buy some of the Extra Virgin types seen in better food stores everywhere. When mixed with some Garlic you have your own medicine at each meal to help protect you from our polluted environment.

Olive oil may protect against stomach ulcers and cancer
By Stephen Daniells
08/02/2007 - Polyphenols found in olive oil, a mainstay of the Mediterranean diet, may prevent infection with the Helicobacter pylori bacteria, said to be the cause of millions of cases of gastritis and peptic ulcer disease each year.
The new research by researchers from the Spanish Institute de la Grasa, and the University Hospital of Valme, report that, under their simulated in vitro conditions, the polyphenol-rich extra virgin olive oil exerted anti-bacterial effects against eight strains of H. pylori, three of which were said to be resistant to antibiotics.
"These results open the possibility of considering extra virgin olive oil a chemoprotective agent for peptic ulcer or gastric cancer, but this bioactivity must be confirmed in vivo in the future," wrote lead author Concepcion Romero in the Journal of Agricultural and Food Chemistry.
The researchers state that previous studies have shown that green tea, cranberry juice and certain other natural foods inhibit the growth of H. pylori, the only bacteria that can survive in the acidic environment of the stomach and known to cause peptic ulcers and gastritis.
The new study, the first to look at the potential anti-H. pylori role of olive oil polyphenols, used laboratory experiments to demonstrate that under simulated conditions the healthful phenolic compounds in extra virgin olive oil remain stable in the acidic environment of the stomach for hours.
Indeed, the results show that, under the simulated conditions, over half of the polyphenols found in olive oil could diffuse into the aqueous (water) phase of the gastric juices. Moreover, these polyphenols were found to exert the greatest anti-H. pylori activity.
"The results indicate that the secoiridoid aglycons are not hydrolysed in the acidic environment of the gastric juice," wrote Romero. "It has just been demonstrated that these secoiridoid aglycons, in particular the dialdehyde form of decarboxymethyl ligstroside aglycon, are the most powerful anti-H. pylori compounds of the olive oil."
The olive oil extract's anti-bacterial effects were found to be dose-dependent, and only the weakest extract (one per cent) failed to exert a significant bactericidal activity.
"In view of the low concentration required to exert bactericidal action against H. pylori by the dialdehydic form of decarboxymethyl ligstroside aglycon, it is promising to carry out studies in vivo with extra virgin olive oil to prevent and control peptic ulcers and gastric cancer caused by this bacteria," concluded the researchers.
The results of the study may keep consumer interest in olive oil high, following other studies linking the diet to lower incidence of cardiovascular disease (CVD) and certain types of cancer.
Indeed, Mintel's Edible Oils report said that the UK olive oil market has been on fire since 2000, growing by 39 per cent to date in order to break through the 100m pound mark.
