I like to think that i have a healthy diet and get these essential fatty acids from other foods, we eat fish once a week and other meats, am seriously buying into having more omega 3 in my diet at the moment.
It does seem that i can have my cake and eat it with the expeller pressed steam deoderised coconut oil, just a shame i couldn't afford the organic version.
This oil seems to be the definitive healthy oil in which to fry in i think.
All websites seem to say a mix of oils is best to gain the full benifits. I use to use groundnut (peanut) oil and found the taste to be very nice, thick and oily too, not a bad oil to use healthwise as well, i use to use rapeseed oil too but it got a bad press and not really good for you, small doses ok. I wouldn't stand by what i have read online with regards to oils because most have conflicting intrests, i just went with the most proved, scientific and majority.
BTW my girlfriend has a potassium deficiency for four years now, getting better but very slow, we eat lots of fruit n veg, lean meat, unprocessed food and cook from mainly organic base ingredients. We only have fish once a week and i too am thinking cod liver oil tablets would speed her recovery, really buying into the omega 3/omega 6 ratio and to get your omega 6 at similar values to omega 3 in foods ingested.
