Okay, I’ll start…
Necrosis:
I’m interested in your opinion of raw (uncooked) extra virgin olive oil used as a dietary supplement (in much the same way fish oils/EFA’s are incorporated).
Our absentee comrade Midnite Rambo suggested its use a couple of years ago, and I’ve recently begun drinking about 1½ TBSP at night and/or mornings.
Here’s the article:

Here’s the original thread:

Anyway, how would you rate its benefits compared to other healthy fats/oils?
Thanks.
good question.
decent article i didnt see any references however they are a little off on some things. For one Oleic acid (the main fatty acid w-9) in olive oil has been shown to be a predictor in breast cancer via erthythrocyte membrane saturation. More studies are needed and i haven't researched it extensively but i dont think of it as one of the more powerful anti-oncogenic "supplements". There are studies showing otherwise however, i would suggest it is anti-oncogenic and poses not threat in that regard. The article is a nice summary.
it sure does lower blood pressure, its great for that. However, the article didnt mention that oleic acid (i skimmed it, forgive me if i missed it) is the main player in its hypotensive effects.
Oleic acid content is responsible for the reduction in blood pressure induced by olive oil

Abstract
Numerous studies have shown that high olive oil intake reduces blood pressure (BP). These positive effects of olive oil have frequently been ascribed to its minor components, such as α-tocopherol, polyphenols, and other phenolic compounds that are not present in other oils. However, in this study we demonstrate that the hypotensive effect of olive oil is caused by its high oleic acid (OA) content (≈70–80%). We propose that olive oil intake increases OA levels in membranes, which regulates membrane lipid structure (HII phase propensity) in such a way as to control G protein-mediated signaling, causing a reduction in BP. This effect is in part caused by its regulatory action on G protein-associated cascades that regulate adenylyl cyclase and phospholipase C. In turn, the OA analogues, elaidic and stearic acids, had no hypotensive activity, indicating that the molecular mechanisms that link membrane lipid structure and BP regulation are very specific. Similarly, soybean oil (with low OA content) did not reduce BP. This study demonstrates that olive oil induces its hypotensive effects through the action of OA.
I think this is one of the key uses for olive oil besides the other potentially beneficial constituents. Heart health is majorly important for males especially and olive oil is a very good anti-hypertensive. Combined with cq10 it should be a good stack for the stressed out. Also, it may have effects on memory like the article stated, more research is needed to further tease apart confounding variables though, but i imagine it will be found to have a strong neuroprotective effect. It seems to inhibit cholestrogenesis in glia, the clean up cells if you will of the CNS. One of the possible mechanisms.

Background: Olive oil is a major component of the Mediterranean diet suggested to be beneficial to counteract Alzheimer's disease. Aim of the Study: Our objective was to examine the association between olive oil use, cognitive deficit and cognitive decline in a large elderly population. Methods: We followed 6,947 subjects with a brief baseline food frequency questionnaire and repeated cognitive tests. Olive oil intake was categorized as none (22.7%), moderate (use for cooking or dressing, 39.9%) and intensive (use for both cooking and dressing, 37.4%). Associations between olive oil and cognitive outcomes were examined taking into account socio-economic factors, health behaviors, health measures and other dietary intakes. Results: Participants with moderate or intensive use of olive oil compared to those who never used olive oil showed lower odds of cognitive deficit for verbal fluency and visual memory. For cognitive decline during the 4-year follow-up, the association with intensive use was significant for visual memory (adjusted OR = 0.83, 95% CI: 0.69-0.99) but not for verbal fluency (OR = 0.85, 95% CI: 0.70-1.03) in multivariate analysis. Conclusions: This olive oil-cognition association needs to be confirmed by further studies. However, our findings already shed light on the potential importance of olive oil in the Mediterranean diet and on its beneficial effects on health. Copyright © 2009 S. Karger AG, Basel.
When replacing saturated fats in the diet it certainly effects lipid profiles and it is associated with lower Cardiovascular disease in the southern mediterranean countries.
-Your dosage is right on, it may cause loose stools if you havent already dealth with that and most studies showed that 2 tbsps were the sweet spot for cardio health. I would definitely keep up the usage of it, but it should be used in conjunction with fish oil, it cannot replace it. I beleive the body can make it de novo via delta 9 desaturase--enzyme could be wrong here havent reviewed this in years. I still rank fish oil higher it terms of effect, but olive oil is right up there.
