Bland diets are often recommended following stomach or intestinal surgery, or for people with ulcers, heartburn, nausea, vomiting, and gas. A bland diet allows the digestive tract to heal before introducing more difficult to digest foods.
Many milk and dairy products are permissible, even recommended, on a bland diet, but there are a few exceptions. Chocolate-flavored dairy products are discouraged, as well as any strongly spiced cheeses or high fat dairy products such as heavy cream or half-and-half. Mild dairy foods tend to soothe irritated linings, but excessive fats, cocoa and spices can have the opposite effect.
Most canned fruits and vegetables are fine, with the exception of tomatoes. Tomato-based sauces on pasta are avoided. Bananas are good; however, higher fiber and acidic fruits should be avoided. Baked potatoes and sweet potatoes are very easily digested, but it is important to avoid high fat toppings like butter. Vinegar based foods such as pickles are to be avoided as are sour fermented foods like sauerkraut.
Perhaps, the most difficult adjustment for some to a bland diet may involve meats and proteins. In a strict bland food diet, softer protein sources such as smooth peanut butter, eggs and tofu are encouraged over any type of fibrous or seasoned meat. Certain meats such as poultry or fish are permitted, as long as they are not heavily fried, breaded or processed like sandwich meats. Steamed poultry breast served with a salt substitute would be a typical protein serving while on a bland diet.
A bland diet is designed primarily to help patients recover from gastrointestinal conditions or other medical circumstances in which improved digestion would be essential. It is not especially effective as a long-term weight loss diet, although portion sizes are strictly controlled. Many people find a bland diet to be very difficult to maintain, although some find the use of acceptable spice alternatives does make it easier. Most patients slowly return to a more normal diet once their medical issues have been resolved.
