I am on Day 23 of my first Whole 30. I am looking ahead and planning my reintroduction. The book says to wait a couple of days after re-introducing a food to notice effects. If I reintroduce rice and it goes okay, can I then have rice the day I reintroduce dairy (think Chipotle burrito bowl)? Or am I supposed to introduce each food group and then try mixing them? Thanks!
