Olive oil for blood pressure17th January 2007
Healthy men who don't usually eat a Mediterranean diet can benefit from moderate intake of olive oil, which reduces blood pressure, a study has found.
A research team led by Isabel Bondia-Pons from the University of Barcelona randomly assigned 110 healthy men from non-Mediterranean countries (Germany, Finland and Denmark) and 45 men from Mediterranean regions (Spain and Italy) to include one of three similar olive oils (25 millilitres per day) in their diets.
Blood levels of oleic acid increased by 2-3% in the men from the non-Mediterranean countries, while the men from Mediterranean regions did not exhibit a significant increase in blood oleic acid levels, the study said.
Moreover, at the end of the total nine-week intervention period, the researchers reported that the systolic blood pressure (SBP) of the non-Mediterranean men had decreased significantly by 3%, compared to baseline measurements.
The researchers called for additional studies, particularly with a longer duration, to verify whether small changes or modifications in diet can be made, which would then become habitual.
The results could have implications for people with elevated blood pressure (hypertension), a major risk factor for cardiovascular disease, which causes almost 50% of deaths in Europe, and is reported to cost the EU economy an estimated €169 billion (U.S.$202 billion) per year.
