One way to manage the symptoms of ulcerative colitis is to avoid the foods that trigger them, and another is to identify the foods that help relieve the symptoms. Dieticians and nutritionists who are familiar with the disease can help create a meal plan according to one’s personal needs to manage the symptoms. A diet can help manage the symptoms of the condition effectively, but patients must eliminate trigger foods to prevent flare-ups. Here are some foods to eat and avoid for people with ulcerative colitis to manage the condition effectively:

• Fish
  Some types of fish like salmon and albacore are rich in omega-3 fatty acids and help reduce inflammation during a flare-up. They also help you to stay in remission. Mackerel, herring, and sardines are some other fishes with high omega-3 fatty acid content.
• Eggs
  Eggs are packed with proteins, and including them in the diet is a helpful dietary tip for people with ulcerative colitis, even during a flare-up. Some fortified eggs contain omega-3 fatty acids that reduce inflammation, making them an ideal food for people with this condition.
• Flaxseed
  Flaxseed oil, flaxseeds, and walnuts are better tolerated if ground as they might be unable to eat whole nuts and flaxseeds during a flare-up.
• Lean meats and poultry
  Increasing the protein intake is recommended to replenish the nutrients lost during a flare-up, and lean meats and poultry are great sources of protein.
• Soy-based protein
  For vegans and vegetarians, soy-based protein can be substituted with legumes and whole grains as they are great sources of plant-based proteins.
• Avocados
  Avocados are easily digested because they are calorie-dense but are composed of 70% water. They are also rich in protein and healthy fats.
• Unsweetened applesauce
  This bland food is usually tolerated after an ulcerative colitis flare-up, but some people find it difficult to tolerate during a flare-up.
• Probiotics
  Probiotics are good bacteria that aid in digestion and are found in yogurt, kefir, sauerkraut, miso, and such fermented foods. An important dietary tip for people with ulcerative colitis is to choose yogurt that is low in added sugars as sugar aggravates the symptoms.
• Squash
  This vegetable is a healthy choice as it is well-tolerated by the body, even during a flare-up. Besides, it is full of vitamin C and beta carotene. Varieties of squash like zucchini, butternut, acorn, and spaghetti are best tolerated when cooked as the symptoms are aggravated when squash is consumed raw.
• Instant oatmeal
  Instant oatmeal contains less fiber than the steel cut or old fashioned version of this food, making it easier to digest.
• Plantains
  This food is known to help alleviate acid reflux and also aids digestion.
• Smoothies and juices
  Another helpful dietary tip for people with ulcerative colitis is to drink juices and smoothies as they are nutritious and easy to digest during a flare-up. Carrot juice is an excellent source of vitamin A and antioxidants.
