Although I do not believe food causes UC, I do believe diet comes into play to minimize it. I changed my diet after diagnoses, cut way back on potatoes, and added romaine salads,with high garlic salad dressings (added fresh crushed garlic to dressing) to my meals instead. Also eat a lot of yogurt (probiotics added to it) and fruit and have not had a bad flare since. I do take probiotics, fish oil, and tumeric daily though.
Meds: None so far. Garlic works to ease flares. My GI laughed when I told him and said it was just coincidence.
Diet: Regular fresh garlic, Biobest yogurt daily, Omega 3 supplements, very limited junk food, carbs and processed food, low fat diet. Lots of fresh fruit and veggies (limited potatoes).
Added: tumeric and probiotics.
