i have fair/sensitive skin, so both internal and external factors are a problem - i can't drive by a pasture full of sheep without itching
grains are a biggie for me, plus a lot of other things which i'm still trying to figure out - my diet is pretty basic and as long as i stay away from manufactured/multi ingredient stuff i do fine -
and for me, it's all about
amounts - a little at a time, okie dokie - but if i eat too much of the offender, there's trouble -
