A number of foods are low in fiber, including fish and shellfish, eggs, dairy products such as milk and yogurt, and spices and salt. Fiber content can often be altered during cooking. Many vegetables, for example, lose most fiber content after being steamed or boiled.
A number of cereals, grains and breads can also be naturally low in fiber, especially white bread. Likewise, white pasta and white rice are also low in fiber, but it should be noted that brown rice, whole wheat bread and whole wheat pasta are all high in fiber.
Fruits, once cooked, are also fairly low in fiber; as with vegetables, any natural fiber content is broken down in the cooking process. This makes steamed or stewed fruit ideal for a low-fiber diet. Raw fruit however, still contains amounts of natural fiber, so it is best avoided if pursuing a low-fiber diet.
A number of sauces and condiments are also low in fiber, including mayonnaise, tomato ketchup, simple gravy and some milder mustards. Plain chocolate is also lower in fiber than other chocolate varieties, and marshmallows, honey and syrup are all sweet foods that can be eaten as part of a low-fiber diet plan.
