    No doubt you are the expert and probably right about citric acid being harmless to most people. However, based on my own personal experience,there is no doubt in my mind that it clearly aggravates my eczema, and the same has been observed in the case of other family members. Perhaps we are in the minority, but still, for us citric acid is HARMFUL.

      I too suffer from a reaction to commercial citric acid, but not to any citrus. I understand this relates to the manufacturing process, which derives it from a mould/fungus, as I am also allergic to mushrooms and penicillin (I also react badly to wine and bread mould, which all tie together in terms of moulds/fungus).
      To me, citric acid is to be avoided at all costs, or else I become quite ill and my eczema also flares up. I am glad to see I am not alone in this.

    Intresting personel fact, eating citric acid in fruit does not bother me though citric acid added in food products such as tomato sauce (makes up for the fact food manufactures put less tomatoes in said product) etc gives me stomach problems. The problem is so severe(increased acidity) that I have to consume a cup or two of slippery elm gruel to neutralize(absorb) the acidity so my stomach can function properly again. This is yet another example of how removing various chemical componets out of the food itself become problematic and even toxic. It is said that in order to neutralize the acidity found in concentrated juices, that every 1c of concentrated juice requires 16 c of water. I wonder what 1t-1T of white powder compared to 1c of juice would take?

    I kind of liked the opening soundtrack that used to start every video.

  • I heard that naturally derived citric acid is safe but synthetic can be an irritant. Can you comment on sulfer/sulfites used to make synthetic citric acid? Do you know if they are safe?
