This. I always had very bad skin and seemingly random outbreaks of my dermatitis. Also breathing issues (asthma related) would appear in tandem.

I figured it out when peeling some potatoes and my skin started itching horribly. Turned red and all.

Tried to avoid potatoes and it's a night and day difference for my overall health.

Also: Sweetpotatoes are not potatoes :)
