before paleo, i had a semi white/pasty tongue. i scrubbed, brushed, and scraped at it and it would always go back to the same wall paper paste color. up to this point, my diet was fairly healthy (imo), only water, minimal processed foods, no fast food, but i did eat bread/carbs/grains and moderate amounts of sugar.
back in march when i went paleo VLC for a month, my tongue went to a nice pink color. i was shocked. it was nice to see a clean tongue that looked healthy. anyhow, i eventually introduced white rice and tubers back into my diet (and occasstional ice cream :) ) and remained gluten free. i dont quite remember exactly when, but the white/pastiness came back. yuck!! i was kind of grossed out.
fast forward to today, i started vlc again on 8/1 and my tongue is now pink again.
so my question is.... is your tongue a health indicator as many have claimed? is the white stuff just a growth of the excess sugar in a persons diet? will i live longer now that my tongue looks good hanging out when i drive with the window down?
