The 2020–2025 Dietary Guidelines for Americans (DGA) recommends that people across different age groups follow a healthy dietary pattern.

Eating a nutritious diet that is rich in fruits and vegetables and low in saturated fat can have benefits for everyone, regardless of age, race, ethnicity, or current health status — including constipation. A healthy diet may include:

A 2022 study that examined the association between dietary factors and constipation in adults found that better adherence to the healthy eating index-2015 (HEI-2015) may improve constipation symptoms and facilitate bowel movement. The HEI-2015 is a measure for evaluating overall dietary quality, and researchers score it based on the DGA.

Dietary fiber is the indigestible part of plant-based foods. Fiber helps soften the stool so it passes through the colon smoothly.

A person needs a healthy portion of soluble and insoluble fibers to help prevent constipation. Soluble fiber dissolves in water and helps to slow digestion. Insoluble fiber does not dissolve in water and helps support regular bowel movements.

Sources of soluble fiber include:

Examples of insoluble fiber sources include:

The DGA recommends that adults consume about 22–34 grams of fiber a day, depending on their age and sex.

A 2020 study indicates that consuming food rich in dietary fiber may help with improving gut motility, maintaining gut microbiota health, and preventing the risk of colorectal cancer. Gut motility refers to the movement of food along the digestive system.

Research from 2017 found that low fluid intake is associated with constipation. Additionally, experts suggest that dehydration and low fluid intake may negatively affect bowel movement and lead to constipation.

A person should speak with a healthcare professional if constipation does not go away or if they have a family history of rectal or colon cancer.

People should also speak with a doctor if they have any of the following symptoms alongside constipation:

Doctors recommend that people with constipation increase their fluid and fiber intake to improve bowel movement. A diet plan for constipation may include fruits, vegetables, whole grains, plenty of water, and other fluids. Eating a balanced diet may also help to manage constipation.

Conversely, a person may consider limiting foods that may trigger constipation, such as high fat and processed foods.

If a person has symptoms of constipation that do not go away, they should speak with their doctor. Similarly, if they experience other symptoms, such as blood in the stool, alongside constipation, they should speak with a healthcare professional.
