Food suggestions during flare

Keep your food on baby food level along with as much chicken broth and chicken or turkey that you can handle. Less work for your gut. Low fiber has worked really well to get me to remission. No raw veggies.

At my worst I ate really well cooked carrots, cooked spinach, potatoes (resistant starch is very helpful) and ground meat for meatballs (which has quite a lot of vitamins).

Are you sure it's UC and not IBS causing the problems? It's incredibly hard to tell the difference when flaring but determining which foods cause issues can help hugely. Yes it seemed like all foods did but I managed to find some foods that were tolerated. Some people use protein shakes with fewest ingredients (not me).

Good luck.

for me these things were good but its individual
(at my worst I did not eat a blessed thing for a month- was on fluids/nutrients IV)
salmon, white pasta, white crackers, white bread, a little mozzerella cheese - low fat is better because the oil might be irritating, if you are lactose intolerant skip)pretzels as I improved I ate peeled apples and some very well cooked peeled potatoes, roasted peeled zucchni, roasted and peeled carrots
but take it slowly, get IV fluids/nutrients to give you energy if needed
bowel rest might be good for a very short time (one month is too long but I refused to eat)

ipoop said it all.

i do best with broth, yogurt, meat, eggs, dry curd cheese, potatoes, bananas, and chia seeds. chia seeds have been a recent discovery for me this year in really sopping up diarrhea. they absorb a ton of liquid but the key is taking them right away when you make something. for example, make a smoothie of yogurt, banana, and water or coconut/almond milk and add the chia seeds. drink immediately. if you drink them after they have gelled, they have already absorb the liquid you put them in.

I always eat light stuff, like peanut butter and jelly. Down from 20 to 7 or 8 is great improvement. I would just take it easy, small portions often, and wait until you go from 7 down to 2.
