Consuming Huel powder, Huel Ready to Drink, and Huel bars should be fine if your diverticular disease is in remission, but if you're in an active diverticulitis phase, the ground flaxseeds may get caught up in diverticular pockets and cause irritation so we suggest consuming these Huel products in moderation initially to assess tolerance.
Huel Hot & Savoury would not be suitable if you have diverticulosis (both in remission and active).
