Liver seems to be a very hit-or-miss proposition for people. Once cooked, some find it to be so similar in taste to beef or chicken that it seems silly to complain about. Some insist it has a unique flavor or quality that makes it absolutely revolting, however.
The revulsion does make sense, as the liver is used to filter toxins. The big misconception is that the liver does not actually store these toxins, however. So you aren’t getting any toxins with each serving, just tons of vitamins, folic acid and lean protein.
