There are so many toxins in farmed fish, it should be avoided. Dr Greger says being obese brings back these pollutants from our own fat. So we need to be aware where we buy our foods and keep our bodies lean. Our fat stores bad chemicals that can make us sick for a long long time. These toxins are stored in our fat cells. As the fat cell is used, it releases the toxins back into our body. Everything seems to be polluted today and we can’t avoid it 100% but we should be aware so when there is a choice, we choose the best option. Vegans have the best results here since they do not eat any fish or animal protein.
