Over the years, many have believed that charred food contains carcinogens that can be cancerous because of the acrylamide chemical released during the charring process. However, a recent study showed that the chance of consuming charred meat leading to cancer is relatively slim. Also, it may be more likely that processed meats, such as hotdogs, sausage, and the like, are more to blame than the blackening process. In conclusion, daily consumption of blackened fish may or may not be bad for you. However, enjoying it occasionally doesn't seem to be cause for concern.
