Where the sources say different things
Every side in full, because one line would have to pick one of them.
Each bar is one source’s range, drawn against the line of no difference: left of the line is lower, right is higher. Widths are not comparable between rows.
Potassium and systolic blood pressure
Three sources here, and they say different things: two measured lower systolic blood pressure and one reported mixed results.

How much of this is one source
Read from 39 sources. 37 of the 49 questions here rest on a single source with nothing yet to check them against, and on 6 questions the sources say different things.
What is still to read is kept per ingredient, not per topic, so every ingredient named above carries its own list.
Still to read means nobody here has got to it, not that it was tried and did nothing or that no research exists. A pairing on no list is not a gap: we never set out to read it.
