Artificial ingredients or sweeteners are definitely on the naughty list for ileostomates.
I did the same, got a no sugar jelly and thought I was fine having a sandwich until later my bag nearly exploded with the volume of output. So I read the ingredients and there it was, artificial sweeteners.
See an ostomy dietician if all possible they can tailor a diet that's both hypoglycemic and ileostomy friendly.
Heck I'll have ChatGPT draw you up one. Give me a few minutes. Yea you have to refresh the page because it gives you the older cached one by your browser to supposedly save bandwidth.

ILEOSTOMY + HYPOGLYCEMIA SAFE FOODS
(Gentle on gut, stable blood sugar)
---

PROTEINS (soft & lean)
1–2 eggs (scrambled or soft boiled) whites are better than the yokes mixed in.
3–4 oz chicken breast (poached/shredded)
3 oz white fish (tilapia, cod, haddock) fish can stink up your bag horribly through. I eat tuna noodle casserole and seem fine, so it's a quantity issue I believe.
½ cup low-fat cottage cheese or ricotta
Whey isolate shake (20–25g protein) Excellent!
½ cup soft tofu
---

GENTLE CARBS (low fiber)
½–1 cup white rice (well cooked) cooked like when the ends split because if it absorbs more water in your system it will pancake your wafer off.
½ cup mashed potatoes (no skin) no chunks neither
½ cup oatmeal (well cooked, mix with whey) definitely use soupy oatmeal as you don't want it absorbing too much water in your system
½–1 small ripe banana, not eaten whole, mix with fruit juice like in a smoothie or it causes pancaking
½ cup unsweetened applesauce
1 slice white bread or toast
½–1 cup plain pasta, well cooked.
---

VEGGIES (pureed & soft)
½ cup carrots (pureed)
½ cup zucchini (peeled, cooked, pureed)
½ cup pumpkin or squash puree
½ cup green beans (pureed)
¼ cup spinach (pureed, add to eggs or soup)
---

DRINKS (hydrate + stable glucose)
Sip electrolyte drinks (Pedialyte or Gatorade Zero)
½–1 cup diluted juice (½ juice + ½ water)
½–1 cup lactose-free or almond milk
Low-sugar protein shake, watch it though some like chocolate or have artificial ingredients or have bad effects
Herbal or decaf tea
(Avoid caffeine — increases output and dehydration)
---

HEALTHY FATS (tiny amounts)
1 tsp olive or avocado oil (oiled covered foods like pasta may not digest)
1 Tbsp peanut or almond butter
1 oz low-fat cheese (mozzarella, ricotta) okay low moisture mozzetta is bad as it doesn't dissolve, so try to avoid it.
---

AVOID OR LIMIT
Raw veggies, corn, beans, nuts (blockage risk)
Sugary drinks, soda, candy (spikes & crashes)
Coffee, energy drinks (caffeine = dehydration)
Fried or fatty foods (odor, slow digestion) diarrhea city
Carbonated drinks (gas buildup) tip: let it go flat a little and avoid caffeine and sugar or artificial anything
---

SAMPLE DAY
Breakfast: Oatmeal + whey + ½ banana
Snack: Egg + white toast
Lunch: Chicken + rice + carrot puree
Snack: Cottage cheese + applesauce
Dinner: Fish + mashed potatoes + zucchini puree

---

MEAL SCHEDULE
Eat 5–6 small meals every 2–3 hours:
3–4 oz protein
½ cup carb
¼–½ cup veggie puree
Hydrate constantly
---

SUMMARY:
Keep it soft, low-fat, low-fiber, high-protein, frequent.
Stay hydrated and pair carbs with protein to avoid sugar crashes.
