You should eat 5-6 smaller meals a day at regular intervals so as not to overload the digestive system.

In the initial stage of the disease or its exacerbations, a liquid diet is recommended, e.g. weak tea, blueberry juice with gelatin, or carrot puree. Liquid products are quickly digested, so that the residual food does not irritate the membraneintestinal mucosa. The liquid diet is followed for about 3-4 days until the symptoms disappear. As the symptoms subside, you can add delicate types of cooked meat, fish, poultry, mashed potatoes to the diet. Fruit and vegetables should be served cooked when the stools are firm.

All meals should be boiled, baked in foil or stewed. It is not recommended to fry and bake food in the traditional way.
