Remember, Fish is good for the eyes.We in India cook the fish using spices and eat it for food.Never eat a raw fish.Also we should clean the fish both from inside and outside too.
It depends on the family of fish that you consume. Bottomfeeders tend to have more residual junk in them. While a nice thick slab of shark will yield the highest concentration of omega-3 fatty acids. Essential for cleansing and strengthening the arterial walls. Live Well !!!
