Hi all
I've been on 6000 mg / day fish oil for about 10 days now. Before that, I took 3000 mg / day. The preparation I take contains, per 1000 mg:
180 mg EPA,
120 mg DHA.It might be coincidence, or it might not, but I like what I am experiencing so far. FDA says 3000 mg / day is the upper safe limit for fish oil, but heck, what do they know. They are just a regulatory body, right, so they err on the side of caution. I've read what people like Larry Hoover have to say on the subject, and it makes sense. But if you think I'm killing myself, please let me know.
This got me thinking. Considering the apparent health benefits of n-3 (omega 3), why are fish able to synthesise it, but humans not. What is the evolutionary rationale for why humans in particular, and mammals in general, lost their ability to synthesise n-3? At what point in the evolutionary chain did animals lose their ability to synthesise n-3, and why would this have placed them at a competitive advantage in surviving, as per the principle of natural selection. Do reptiles synthesise n-3? What about dolphins and whales? If fish and dolphins / whales can synthesise n-3, why the gap in between where other mammals cannot synthesise n-3?

I don't know the answer to your question, Klavot.
I have assumed that Omega3's are passed up the food chain when animals eat each other. Thus our lotfed cattle, eating grain, do not contain the same omega 3's you'd get if they lived on natural pasture.
The idea is that grains are now overrepresented in the food chain?
I have assumed that reptiles (like goannas), say, are high in Omega 3s and imagine they would be good for my health. Why don't we eat reptiles? There is crocodile, of course.

Well, I could well be wrong, Declan. I assumed fish are able to synthesise n-3, considering that the classical source for n-3 is fish oil. If not, then where does all that n-3 in fish oil come from?

and ya can get roast for about $5 at Coles or Woolies. I got one for 3.50 for about 1.5 Kg roast last week on special, already marinated and tasted nice.
Or use kanga mince in spagetti etc, I use half kang half beef to cut down the flavour.. just a suggestion
Crocodile is cheap in BN I've heard..
I'm unsure about croc though.. I don't think they don't eat grain, but they may be a bit up the food chain, still New Guinea etc wouldn't have a lot of pollution..
Must cost a bit to feed crocs in croc farms ?? I wonder what they do use now..I had some nice calamari I bought from a trawler yesterday. I'm hoping it supplied the necessary requirements for knee cartiledge building, but I know its wishful thinking that my body will decide to do that with it. I guess it tastes great anyway:)

No, TJ, I don't think any illegal immigrants have been fed to crocodiles.
Some may have had their boats damaged by government agents and then been eaten by crocodiles at sea, safely away from the Australian shoreline....I suppose that is possible.

;-) LOL
almost fed myself once to them crocs.. I jumped with fright when I climbed up this ladder which turned out to be a feeding tower to a croc farm.. never saw anything so speedy in all me life.. .. luckily I jumped in right direction(that is not into the farm) ..phew!
Didnt realise exactly what I was climbing and I was really surprised by the speed of the movement thru the water and mud..
I just wanted a better look, which meant climbing to the top of the fence ...although I should have had more sense at the time(nah, I'm not thick..). It was many years ago in New Guinea.. LOL(now)
Talk about jumping with surprise/fright.. wonder why we do that anyway?Last time was after watching this scary movie and someone sneaking up behind me, so I still jump:)

I've figured it out. Apparently fish do not synthesise n-3 either. They obtain it from the algae they feed off.

Yes, Klavot, you can actually buy Omega3s made from algae. Vegetarians do this.
