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?
