Foods that everyone agrees on and keep me healthy

I know everyone has to test things out but give me your diet staples please. I want a foundation to build on.

Soup, rice, cream of wheat, bananas, apple sauce, almond milk and Chex cereal, pb on saltines or graham crackers, plain pasta with butter.

Nothing was ever safe for me, but less quantity always had less impact. My go-to staple was usually PBJ or soup.

I don't personally think it's all that related in the big picture. More problematic for how many times you're on the toilet immediately following the consumption of "bad food". My diet never effected my ability to get in or stay in remission. If you know what works for you, I suggest you stick to it. If you are trying to figure it out, I'd try a food journal.

Homemade chicken soup is probably one of the few things almost everyone agrees is healthy and gut-approved. After that it's not so easy to find foods that are universally agreed on.

My gut doesn't tolerate yogurt, even home-made SCD yogurt. I LOVE yogurt but my gut says no (tried multiple times over the years).
My basics for making unhappy gut happy again: meat (protein) and well-cooked low-fiber veggies including potatoes. If I ate only these foods my gut would be super happy all the time. Asian food like curries are also gut-friendly to me, especially home-made so I know what ingredients went in.

Good luck finding your safe foods and building from them.
It takes a while to figure it out. I've always been able to eat in restaurants as long as they have a burger or chicken on the menu but home-cooked is my favorite.

Chicken soup, bananas, cooked carrots, potatoes

After a day of an admittedly unhealthy chicken soup mix (I boiled and added the chicken), eggs and green beans and Gatorade/water...I was really gassy with diarrhea but it seems my bleeding is way down. Sign of the diet working? or is this just the ups and downs of my first flare? It's almost unbelieveable how happy you can be to not see blood in the toilet!

Oh there the blood is. While we're at it any tips for the morning i waste my morning waking up too early. And basically camping near my toilet. I have one really early class that I keep missing.

It's a short list.

Here's more good news: it varies with each person! yay!

When I am flaring I have the hardest time digesting high fibre foods, especially raw vegetables. I would feel the bad "results" within a couple of hours of eating - in my case meaning cramping, running to the bathroom, that kind of thing. Blood for me is not something specifically related to one food or another, but rather an indication of things being ulcerated or healing.

So what you might do is get to know your own body and how soon a "bad" food has a bad result... then try something and see if it gives you that reaction in that time frame (or longer, to be sure). And try it a few times and see you respond the same way. Then you can put that on your "safe" list.

How about focusing on foods that biology recommends are nutritious? Specifically the fuel our mitochondria tend to favor for energy production and cellular regeneration.
I mean, one can say they can survive on junk food- but running on empty calories for an extended time may aggravate or even be a key factor of UC.
When we process junk food our mitochondria expel an excess of free-radicals responsible for inflammation and mitochondrial dysfunction. This can weaken our epithelium/mucosal lining, allowing in harmful bacteria and toxins which cause further inflammation. Short fatty chain acids (whole grains, vegetables, fruit) are one example.

I'm paleo-ish at the moment and eliminated nightshades.

One specific item I want feedback on: Honey Nut Cheerios w/ almond milk?

Not me. Almond milk I've looked at has ingredients my gut hates. No cereal for couple years due to fiber. But your gut may be fine with both of those. My gut is pretty grumpy about a lotta stuff. Hoping yours is better than mine.

But....going out to dinner tomorrow for Thai food, gut loves it, go figure. Many Thai restaurants have identified food on menu as Gluten-Free so it's something other people have found works for them too. I am not celiac but removing gluten has been a good thing for me.
