Also, what are the dangers with omega 6?
There's not a definitive danger, but there is evidence that higher omega 6 consumption can lead to inflammation. The thing is tilapia is very nutrient rich and even farmed tilapia has a comparable level of omega 3s as probably most other fish. So if your diet is relatively balanced then you most likely aren't going to experience this problem. Humans need both of those things and inflammation isn't even an all bad thing. It's a necessary body to some degree.
Go4 It might chime in with a different viewpoint, and obviously if you've seen his pics, you shouldn't disregard anything he has to say about diet, but at the same time, even scientific bodies make contradictory nutritional recommendations. So anyone's advice should be taken with a grain of salt.
