I think there's a joy to be had in taking readers where they just don't want to go. If you are writing a properly realist novel, then don't blink. Why not see something for what it is and render it truthfully? I find it a good way of going about writing - not to blink.
India introduced Britain to vegetarianism - see Tristram Stuart's excellent first book on this - and it is possible, indeed all too easy, to be a vegetarian in India and eat extraordinarily good, varied food every day, with very few 'repeats.'
It's always good to get good reviews. I read my reviews. There are a lot of writers who don't read their reviews at all. I read them; then I put them away because it's not good to engage with them too much.
