How do you differentiate the symptoms between sulfur and nitrogen deficiencies?

It becomes easier to distinguish between sulfur and nitrogen deficiency symptoms as the symptoms reach this intermediate stage.

There are many who believe thiol content is more significant than actual sulfur content of foods. When a food contains thiols, it can cause elevation of sulfur. When foods don’t contain a high amount of thiols, it is believed the sulfur in these foods stays complexed with methionine and does not significantly raise sulfur levels.

What foods should not be eaten with sulfur in them?
