If this is the new standard, rather than 4:1, and 2:1, then given meats are at best 2:1, does that mean that a healthy diet MUST include seeds and/or fish?
I have heard that ALA is not an ideal nutrient because its poorly converted (only about 10% is converted into longer chain omega-3's, which means you need 10x as much for the same effect). It also is primarily found in hard to digest foods like seeds and grasses..
That would seem to imply that our evolutionary diet and a healthy diet must include shellfish and seafood, being its the only omega 3 thats readily converted into useful chemicals..
And, if ALA is not even 1/10th as good as DHA etc, its possible this 1:1 ratio is a pile of BS being it doesnt make any distinction between EPA/DHA and the far less useful ALA!!!
I mean what we need to know is the ratio of specifically EPA/DHA to omega 6s that we need to be healthy...ie, how much fish or fish oil should we eat...(especially given that it seems like this 6/3 ratio is crap because it includes far less useful ALA as being equal to EPA/DHA, which it apparently isnt at all)
Lets just put ALA aside unless anyone to wants to eat a few kgs of seeds every day!
Clearly we can survive on omega 3s from other sources, like land animals and seeds, but if its so important, and poorly converted, it would imply that fish/shellfish/algae etc is the source we evolved to use.....so how much do I need to eat to get good health on a paleo diet....1 times a week? 2? three? half of my meat intake?
I mean if half or less of that "1:1" ratio is ALA, then the actual ratio if your eating fish would then be 2:1 or more...(it seems unlikely most people would even be eating half of there omega 3 from fish/seadfood, so that number could easily go back up to 4:1, or 8:1 if u are getting ur omega 3s from fish oil or seafood)
I regularly snack on tuna, eat shrimps and have the odd fish meal...but is that enough for this "ratio"...
I think I may try and get two meals a week of fatty fish.., of some low mercury species...
Confusing...anyone got any studies on omega-3/6 ratios that actually seperate DHA/EPA from ALA?
(And grr, alot of fish are high in mercury now, which is super bad if we actually require it for optimal health....)
BTW how the heck did all that mercury get into the ocean?
