Good points, but he’s misstating the fish oil study when he says that the cancers were elevated in those who took the supplements. They were elevated in those who had the Omega 3’s in the blood.
I had a physical earlier this week and told my doctor that krill oil really upset my system. She responded that concentrated Omega-3's like krill oil can do some nasty things to the G-I track, so I guess it creating other issues isn't too much of a surprise. She said that Omega-3 supplements in moderation have benefits far in excess of the potential problems. She told me to continue taking fish oil in moderation (because it doesn't upset my system).
