interesting.. cus i was thinking about this the other night while laying in bed. i never before now kissed a vegetarian or vegan.. my boyfriend has been vegan for about 15 years and i don't notice the "funk" i noticed when i kissed meat-eaters. not to be gross.. but even if he hasn't brushed his teeth all day, his breath and mouth aren't funky. i just think it's because he isn't eating anything thats rotting inside his stomache and colon and between his teeth..
right, fruits, veg and grains are preserved forever. (ha) he probably just is cavity/ gingivitis free for now and eats a ton of chlorophyll in the veggies. Time changes that, see what you get to look forward to?
