Yeah, it's true. It's better to cook without oil. Fats cause inflammation. If you are in a raw fruit diet than yes, it's good to consume 1 tbsp a day of raw olive oil. Everyone's body is different, you just gotta do what it's best for you but always vegan because it's the best lifestyle. For your health and for the planet..
Hey, if it works, it works. Not something to generally recommend as a go-to...it a fairly mediocre fat source, not much nutrition and an Omega 6 to Omega 3 ratio of 8:1. That is the same ratio as butter and lard! And has been shown to cause similar patterns of cardiovascular disease.
Canola oil is far superior with a 2:1 ratio, if you're going to use oil. Flax oil is 0.3:1 and the very best oil to supplement with.
A lecture on the importance of that ratio to vegans:
For me nuts are better than oil. I've never taken oil and felt good afterward, usually the opposite. Pistachios, walnuts and almonds, however, make me feel awesome (in moderation).
Mabe fish with omega 3 DHA would be the 'healthiest'
but not really... because of all the mercury, radiation, oil, and shit contamination in the sea, and of course its not necessary.... so why kill an animal and contaminate the sea?
