Some low-fiber vegetables are asparagus, cucumber and zucchini. Mushrooms and carrots are two other vegetables with a low fiber content. Vegetables low in fiber such as these are good for people who have just had surgery or have other medical conditions impairing their digestion.
When served without its fibrous base, asparagus has a fiber content of 1.8 grams per 1/2-cup serving, making it one of the vegetables with the lowest fiber content. Asparagus cream, made of pureed asparagus, vegetable broth and cream, is a gentle way to serve this vegetable.
Cucumber and zucchini have almost no fiber content once their skins are removed. As a general rule of thumb, one should remove all vegetable skins in order to consume as little fiber as possible. Skinless cucumber has 0.3 grams of fiber per 1/2-cup serving, whereas skinless zucchini has 0.9 grams of fiber per the same size serving.
Mushrooms have one of the lowest fiber contents of any vegetable. When consumed raw, a 1/2-cup serving of mushrooms contains 0.5 grams of fiber. Raw mushrooms are preferable for a low-fiber diet as cooking mushrooms increases their fiber content slightly. However, the amount of fiber in a 1/2-cup serving of cooked mushrooms is only 1.7 grams, which is still considered a low fiber content.
