I have wavered back and forth on this GF thing for a really long time now. I've been keeping a food journal for months and here's what I've noticed - while I get bloated about half of the time when I eat GF, I consistently get bloated every single day when I eat gluten. And I believe it also makes me very tired, which makes sense if I can't digest it. So I am going to give the GF diet a real go.
As far as the avocado - I eat it in all sorts of things! I like to eat sliced chicken and avocado between rice cakes for lunch (tip - if you make the "sandwich" in the am and let it all sit together for a few hours, the rice cakes soften up a bit by lunchtime!). I also mash it up, add some sea salt and sometimes some garlic powder (and whatever else you can tolerate - diced onion, diced tomato, etc.) then I eat this with corn chips, carrots, etc. I also dice it on top of dishes such as rice and beans. Mmm! It's my favorite!
