I don’t eat anything that I find horrifying unless two conditions are met:
- The nutrients are absolutely essential
- There’'s no other source for getting them
The nutrients that liver provides are not unique to it.
Liver has a massive amount vitamin B12. But clams are equally efficient at providing it.
Liver has a high amount of copper. But oysters are just as good.
Liver provides a high dose of vitamin A. But butternut squash has more. Kale isn’t quite high, but on a calorie basis is competitive.
This exercise could be done for any food. I don’t hate liver, but I really like shellfish, and eat plenty of nutrient dense veggies. So it isn’t nutritionally necessary for me to eat liver.
