To simplify the sulphur information, this is the rule I follow:

"No eggs" (because they contain a lot of sulphur)

We all need sulphur in our diet as it is arguably one of the most important minerals we have. I don't believe we should avoid all of the foods listed in the high-sulphur food list because in many cases the benefits outweigh the risk.

Just keep an eye on what you eat and how you feel after. If you notice mercury symptoms consistently after a certain food, just eliminate it from your diet. That's what I do.

Hope this helps.
