#362--Many experts recommend against eating fish these days due to fears of mercury contamination. But this risk can be minimized if you eat lower down on the food chain. Bigger fish eat smaller fish and, thus, condense any toxins in the fish on which they feed. Therefore, to protect yourself, consumption of larger fish like tuna should be kept to a minimum. However, maintenance of healthy gut flora offers another level of protection as the good bacteria bind with the mercury and prevent it from being absorbed. If only you could say the same about the amalgam fillings in your mouth.
