Grains are not well tolerated by many people... whole grains in particular.
I now only eat wholegrain rice if I feel like having a headache, getting all achy and flu-like and fatigued. If I really feel like doing myself in... I mix it with potatoes in a 'suicide dish' like homemade perogies.
I bet you can figure how often I eat whole grains once I put this together.
I used to be the whole-grain queen because I had bought into the "it's better for you" message. Took me ages to figure this all out. Finally, one Ukrainian Christmas when I finally got the wherewithall to try and replace our old gluten perogy dough recipe with a gf one (and was successful) - I paid for it for the whole week after Christmas!
This year I used refined white rice flour and stuffed half the perogies with meat. I ate about 4 of the potato perogies, all the rest meat... and I was just fine! Hooray!! 'Cause I love perogies!
