To the OP re plants and fibre interference with the digestion, this happened tome too after about 18 months being ZC/VLC. If you want to get the vitamins/minerals of the veg without the digestion drama, your best option is to make a green juice, you only need a cup or so every morning. Then build your tolerance gradually if you can, I am still struggling with it, my body can't digest veg/fruit and I get joints pain when I eat fresh fruits/veg, but managed to adapt to high protein/fat plants such as avocado or quinoa, in fact I have less trouble digesting white rice/potatoes than veg/fruit (which I only eat on very rare occasions at family invites, surprisingly starches do not cause me joints pain, but perhaps this is because I have them on very rare occasion)
I use Olive oil, I've been use it often recently, but I also use coconut oil. Mediterranean populations use olive oil as a main fat source, have done so for many generation.
