I’d advise against it.
Even though sardines may have a lower amount of mercury than most other fish, they still contain it, and mercury is very hard for the body to get rid of. It accumulates and doesn’t cause problems… Until it suddenly does. And it’s not fun.
A friend of mine ate fish 4-5x weekly (not just sardines tho) for about 6 months, and he ended up in the ER and on a very restricted detox diet and meds for almost a year.
So, even though sardines are low on mercury as it gets, I’d limit myself to at most every other day.
For what? Being decent human beings?
