Guest guest Posted September 7, 2006 Report Share Posted September 7, 2006 Hi folks: Another two items as regards olive oil. The Nurses' Health Study found that those who consumed olive oil were only marginally healthier than those consuming the average (dreadful?) north american diet. Not a strong recommendation, and very much in line with Jeff's remarks below. This suggests that olive oil is somewhat less atherogenic than saturated fat, but ............ (Source: Willett, 'Healthy Women, Healthy Lives'). In addition, PMID 15182405 compared the differences between residents of Crete who had heart disease with a matched control group without the disease. In many respects those with heart disease should have been healthier. They ate fewer calories, less cholesterol and less trans fats than the control group. Why were they sick when the control group was not? Perhaps because they ate more total fat, less carbohydrate, less fibre and MORE MUFA, which in Crete is principally olive oil.

Guest guest Posted September 7, 2006 Report Share Posted September 7, 2006 I just put together this chart comparing all the nutrients listed in the USDA database for the equal calories of Olive Oil, and Green Leaf lettuce. In CR-ON, nutrient density (nutrients per calorie) is a key factor in choosing foods...not nutrient per gram or nutrient per serving.... (which is how they are often promoted in the media or by well intentioned [but misinformed] health professionals) As you will see, if this comes through.. the green leaf lettuce wins in EVERY category including Vit E, Essential Fats, Essential Fat ratios, and every other vitamin and mineral.......

Guest guest Posted September 8, 2006 Report Share Posted September 8, 2006 Hi folks: It may also be worth noting that the source of this information is: " Municipal Institute for Medical Research in Barcelona, Spain. " Spain, of course, produces nearly half the world's olive oil, more than twice the amount of the second largest producer, Italy. So there are very strong reasons why, for marketing purposes, they might wish to present the product only in the most beneficial light possible. And certainly not do studies to see whether the product is actually atherogenic, and/or ignore any studies that might seem suggest any kind of problem with the product. Hardly a disinterested source of information, in other words.
