can i alkalize without causing heartburn or upsetting bowel ph?

hi everyone :) i do try to read and learn but, there is so much i don't understand. i've wanted to alkalize, for general health but also hoping to lower the ph of my urine for the sake of my kidneys, but... when i take baking soda (just 1/2 tsp, sometimes with lemon juice, sometimes without), i start to get heartburn (a problem i don't normally have) ...and i've read that it's good for the ph of our digestive tract (and female parts - i'm female) to be slightly acidic, so... is there any way i can strike the right balance?

and wanted to ask really quick... should i use lemon juice w/ baking soda or, no? i'm concerned that while the baking soda is alkaline, the LJ is acid so i'd be undoing the good of the baking soda at the same time, or they just neutralize each other...? (but i also have a food chart that says LJ is actually ALKALIZING as well ...but then i still worry the LJ will at least not be good for my teeth)

thanks to anyone willing to help me learn :) missy Tweet
