Having seen the Clever Guts Book comments on Italian Olive oil I was minded to comment that as a regular daily drinker of olive oil the best I have found is GREEK . Apparently the most beneficial is that derived from the Koroneiki olive in terms of it being a good source of Polyphenols and Flavonoids, which help to fight against harmful free radicals.It also tastes as good as any I have tried and is “drinkable ” .I buy from http://www.maltbyandgreek.com . Perhaps these guys are worth checking out ? Be interesting to see if this is really the best in terms of health benefits – I cant say myself one way or the other and I have no interest in that company other than being a very small time customer .
