Get deep sea fish. Stuff like tuna, salmon, swordfish. You can't avoid contaminants altogether, unfortunately. At this point, all there is to do is try your best. As for carbohydrates, why? Eat green vegetables, the occasional piece of fruit, and otherwise don't worry about it.

It just so happens that they are cheap and easy to produce and have high profit margins, so they want you to think you need them. Take care, John Pavao ---------- >I'm so confused!
