Many thanks! I am aware of the moreless forum & of Invincible's blog although I have not taken the time to really study...I am aware of the acid/alkaline balance..in a vague kinda half-formed way. My knowledge is incomplete at best. Our diet at the present time is (I believe) alkalising. It hasn't always been that way, though...I will absolutely study this further..I just checked out a few posts and learned that lemon/lime makes calcium more assimilable...didn't know that! There's so much to learn! Thanks for giving me a little push... :)
