Using Olive Oil in Your Diet May Prevent a Stroke
ST. PAUL, Minn. -
A new study suggests that consuming olive oil may help prevent a in older people. The research is published in the June 15, 2011, online issue of the medical journal of the . 鈥淥ur research suggests that a new set of dietary recommendations should be issued to prevent stroke in people 65 and older,鈥 said study author C茅cilia Samieri, PhD, with the University of Bordeaux and the National Institute of Health and Medical Research (INSERM) in Bordeaux, France. 鈥淪troke is so common in older people and olive oil would be an inexpensive and easy way to help prevent it.鈥 For the study, researchers looked at the medical records of 7,625 people ages 65 and older from three cities in France: Bordeaux, Dijon and Montpellier. Participants had no history of stroke. Olive oil consumption was categorized as 鈥渘o use,鈥 鈥渕oderate use鈥 such as using olive oil in cooking or as dressing or with bread, and 鈥渋ntensive use,鈥 which included using olive oil for both cooking and as dressing or with bread. Samieri said the study participants mainly used extra virgin olive oil, as that is 98 percent of what is available in France. After a little over five years, there were 148 strokes. After considering diet, physical activity, body mass index and other risk factors for stroke, the study found that those who regularly used olive oil for both cooking and as dressing had a 41 percent lower risk of stroke compared to those who never used olive oil in their diet (1.5 percent in six years compared to 2.6 percent). Olive oil has been associated with potentially protective effects against many cardiovascular risk factors, such as diabetes, high blood pressure, high cholesterol and obesity. In an accompanying editorial, Nikolaos Scarmeas, MD, of Columbia University and a member of the 好色先生 noted that it is not clear which particular elements of olive oil could be protective, while the effects of olive oil could even be indirect by making other healthy foods tastier. He also cautioned that only future clinical trials can increase confidence in the findings and potentially lead to stroke prevention recommendations. The study was supported by INSERM, the Institute of Health and Public Development, Sanofi-Aventis, the Foundation for Medical Research, the National Workers Health Fund, the General Directorate of Health, the Mutual General of National 好色先生, the Institute of Longevity, the Regional Governments of Aquitaine and Bourgogne, the Foundation of France, the Ministry of Research, the French National Research Agency, and Lipids for Industry, Safety and Health.
