In this article, we will explore the relationship between food and constipation. Many people experience digestive issues due to certain foods or dietary habits. However, it’s important to note that constipation is often caused by a combination of factors and is not solely dependent on a single food item. By understanding the impact of different foods on your digestive system, you can make informed choices to manage constipation effectively.

Food as a Constipation Cause

Constipation is usually a result of various factors, including food choices, lifestyle behaviours, and genetic factors. It’s common for individuals with constipation to start eliminating different foods from their diet in an attempt to alleviate symptoms.

However, it’s essential to manage bowel movements rather than restrict the diet excessively.

Dairy Products

Dairy products, such as cheese and milk, are often associated with digestive issues. While some individuals may be sensitive to cow’s milk products, more research is needed to determine the prevalence of dairy-induced constipation in adults. For chronic constipation, it may be advisable to switch to non-dairy alternatives like almond, soy, or oat milk. However, completely eliminating dairy products is not always necessary, as they can provide essential nutrients like vitamin D.

Red Meat

Contrary to popular belief, red meat itself is not constipating. However, consuming high amounts of red meat can lead to a lack of fibre in the diet, as people tend to prioritize meat over fibre-rich foods. To maintain a balanced diet, it’s advisable to incorporate fibre sources like whole grains, fruits, and vegetables alongside red meat consumption.

Processed and Fried Foods

Processed and fried foods, often associated with fast food, can contribute to constipation due to their high-fat content and low fibre content. These foods can slow down the digestive system’s motility, making it difficult for food to pass through the colon. To prevent constipation, it’s important to include an adequate amount of fibre from other sources in your diet and reduce the consumption of processed and fried foods.


Sweets, particularly those high in sugar and low in fibre, can be constipating. Candies and sweet treats that lack fibre can disrupt the natural flow of digestion. While it’s not necessary to eliminate sweets entirely, it’s advisable to consume them in moderation and focus on a fibre-rich diet to maintain healthy bowel movements.

Eating Less

Significantly reducing your food intake, whether due to a diet or other reasons, can lead to constipation. The stomach needs to expand during a meal to trigger the gastrocolic reflex, which helps empty the stool. If there isn’t enough food in the stomach, this reflex may not occur. If you’re reducing your food intake, it’s important to ensure an adequate fibre intake to support healthy bowel movements.

Changing Your Diet

When you deviate from your usual diet, such as when travelling or trying different cuisines, it can disrupt your digestion and potentially cause constipation. The digestive system prefers consistency in the diet. To mitigate this issue, consider maintaining some dietary routines while travelling, such as bringing your daily fibre cereal or planning for possible constipation by having over-the-counter laxatives like Miralax on hand.


Certain medications, including those for allergies, anaemia, reflux, nausea, blood pressure, psychiatric disorders, or pain, can contribute to constipation. It’s crucial to discuss any constipation-related concerns with your healthcare provider if you’re currently taking medications. They can provide guidance on managing constipation while ensuring the necessary medication regimen is maintained.

How to Tell if You Have Severe Constipation—And What to Do About It

While occasional constipation is common and can often be managed with dietary adjustments, severe or persistent constipation may require medical attention. If you experience severe symptoms such as intense abdominal pain, bloody stools, or prolonged periods of constipation, it’s important to consult a healthcare professional for a proper evaluation and personalized treatment plan.


Understanding the relationship between food and constipation is essential for maintaining a healthy digestive system. While certain foods and behaviours can contribute to constipation, it’s not necessary to completely eliminate them from your diet. Instead, focus on managing bowel movements by incorporating fibre-rich foods, maintaining dietary consistency, and making informed choices regarding medication use. By adopting a balanced approach, you can effectively address constipation without unnecessarily restricting your diet.
