I flew recently with all of my IP stuff in my carry on bags. All of my packets & bars went through...no questions asked. Also, I packed a weeks worth of cut up cucumbers & cauliflower. I put 2 cups in each ziplock so that everything was measured up. I packed those in a cooler with a couple of ice packs in with my carry on, too. All went smoothly.
Now my body screening, and pat down, on the other hand...
Enjoy your trip!
