4 min read

According to the National Institutes of Health, malabsorption can lead to deficiencies in key minerals like calcium and iron. Knowing what should I eat to fix malabsorption is crucial for managing symptoms and restoring overall nutritional health.

Quick Summary

Managing malabsorption involves adopting a diet rich in easily digestible, nutrient-dense foods, often supplemented with specific vitamins and minerals. Dietary modifications target the root cause, such as avoiding gluten for celiac disease or reducing fat for bile acid issues, while promoting gut healing with probiotics and other supportive nutrients.

Key Points

Start with the basics: Focus on smaller, more frequent meals to ease the digestive load.
Boost calories with easy-to-digest sources: Prioritize high-protein and high-calorie foods, using lean proteins and potentially MCT oil for energy.
Moderate high-fat and high-fiber foods: Limit or reduce high-fat meals and high-insoluble fiber foods during flare-ups to reduce symptoms.
Enhance nutrient absorption with smart pairings: Combine iron-rich foods with vitamin C and fat-soluble vitamins with healthy fats to boost uptake.
Consider specific exclusions: Follow a gluten-free diet for celiac disease or a low-lactose diet for lactose intolerance to address the root cause.
Support gut health with probiotics: Incorporate fermented foods or probiotic supplements to aid digestion and promote a healthy gut microbiome.
Work with a professional: Always consult a healthcare provider or dietitian to confirm your diagnosis and create a safe, personalized nutrition plan.

Understanding the Causes of Malabsorption

Malabsorption syndrome occurs when your small intestine cannot absorb enough nutrients from the food you eat. This can result from a variety of causes, including intestinal surgery, inflammatory conditions like Crohn’s disease, or infections. The specific dietary approach to correct malabsorption depends heavily on the underlying condition. It is critical to work with a healthcare professional or a registered dietitian to receive an accurate diagnosis and create a personalized nutrition plan.

Foundational Principles of a Malabsorption Diet

Regardless of the cause, several core principles can help manage symptoms and improve nutritional intake. These strategies are designed to reduce the workload on your digestive system while maximizing the absorption of essential nutrients.

Eat Small, Frequent Meals: Instead of three large meals, consume six to eight smaller meals throughout the day. This puts less stress on the digestive system and gives the body more opportunities to absorb nutrients from food.
Prioritize a High-Protein, High-Calorie Intake: Chronic diarrhea and reduced nutrient absorption can lead to unintentional weight loss and protein-energy malnutrition. A diet focusing on lean, easily digestible protein sources and high-calorie foods can help replenish depleted energy and protein stores.
Moderate Fat Intake: In cases of fat malabsorption, reducing dietary fat can minimize symptoms like steatorrhea (fatty, foul-smelling stool). Lean proteins and foods prepared through steaming, baking, or broiling are preferable to fried or fatty alternatives. Medium-chain triglycerides (MCTs), found in coconut oil, are an easily digested fat source that can be used to add calories without exacerbating symptoms.
Stay Hydrated: Frequent diarrhea can lead to dehydration. Drinking plenty of water is essential. Avoid excessive caffeine and very sugary drinks, as they can worsen gastrointestinal distress.

Addressing Nutrient-Specific Malabsorption

Different nutrients require different strategies for proper absorption. Pairing foods correctly and considering supplement forms can make a significant difference.


Nutrient Deficiency	Dietary Strategies to Improve Absorption	Key Considerations
Iron	Pair non-heme iron sources (beans, lentils) with vitamin C-rich foods (citrus fruits, bell peppers). Choose heme iron sources (meat, poultry, fish) as they are more readily absorbed.	Avoid consuming high-calcium foods, tea, and coffee near iron-rich meals, as they can inhibit absorption.
Calcium	Ensure adequate vitamin D intake, found in fatty fish, eggs, and fortified products. Consume calcium in smaller, multiple doses, and include calcium-fortified foods like juices and cereals.	Avoid pairing with phytate-containing foods (whole grains, bran) and excessive amounts of oxalates (spinach, rhubarb).
Fat-Soluble Vitamins (A, D, E, K)	Combine vitamins A, D, E, and K with healthy fats like avocado, olive oil, and nuts to facilitate absorption.	Consider water-miscible or liquid forms of fat-soluble vitamin supplements if fat malabsorption is severe.
B Vitamins (especially B12)	Consume B12-rich foods such as meat, fish, eggs, and dairy. In cases of severe deficiency or intrinsic factor issues, injections or high-dose supplements may be necessary.	Probiotics can help improve B vitamin homeostasis in the gut.

Foods to Include and Exclude

Foods to prioritize:

Lean Proteins: Fish, chicken, turkey, eggs, and tofu are excellent, easily digestible protein sources.
Easily Digestible Carbohydrates: White rice, cooked potatoes without the skin, and refined white bread or pasta are often better tolerated during flares.
Healthy Fats: Avocado, olive oil, and medium-chain triglycerides (MCT) oil, particularly for fat malabsorption, can provide necessary calories.
Cooked Vegetables: Cooked, skinless vegetables like carrots, beets, green beans, and asparagus tips are gentler on the digestive system than raw varieties.
Probiotic-Rich Foods: Plain yogurt, kefir, and sauerkraut contain beneficial bacteria that can aid digestion and improve nutrient absorption.

Foods to limit or avoid:

High-Fat Foods: Fried foods, fatty meats, heavy sauces, and full-fat dairy can worsen diarrhea and other symptoms.
High-Fiber Foods (during flares): Insoluble fiber from raw vegetables, nuts, and seeds can be difficult to digest. Cooked, skinless fruits and vegetables are better tolerated initially.
Trigger Foods: This includes gluten for those with celiac disease and lactose for those who are intolerant. Use a food diary to identify individual triggers.
Sugary Drinks and Sweets: High sugar content can aggravate symptoms and should be limited.

The Role of the Gut Microbiome and Supplements

The gut microbiome plays a vital role in nutrient absorption. Restoring a healthy balance of bacteria can improve digestive function. Consuming fermented foods like yogurt or kefir is beneficial. Probiotics and prebiotics can also be taken as supplements to support the growth of beneficial gut flora. Digestive enzyme supplements may be necessary for conditions like pancreatic insufficiency to help break down food for absorption.

Conclusion: A Personalized and Collaborative Approach

Addressing malabsorption requires a multifaceted approach, with diet being a cornerstone. While general guidelines exist, the most effective plan is personalized based on your specific condition and deficiencies. Combining a nutrient-dense, easily digestible diet with strategic supplements, often under the guidance of a healthcare provider or registered dietitian, is the key to managing symptoms and restoring your health. Consistent follow-up and monitoring are essential to ensure the plan remains effective as your body heals and adapts.

Frequently Asked Questions

Medium-chain triglycerides (MCTs), found in coconut oil, are often recommended because they are absorbed directly into the bloodstream and do not require bile acids for digestion. This makes them an easier fat source for the body to utilize compared to long-chain fatty acids.

Dairy tolerance varies widely depending on the underlying cause of malabsorption. Individuals with lactose intolerance should avoid or limit high-lactose dairy, while some may tolerate small amounts of cultured products like yogurt or aged cheese. Lactase supplements can also be used.

To increase iron absorption from plant-based (non-heme) sources like beans and lentils, pair them with foods rich in vitamin C, such as citrus fruits, tomatoes, or bell peppers. Avoid drinking coffee, tea, or milk with iron-rich meals.

Probiotics introduce beneficial bacteria to the gut, which can help rebalance the microbiome and improve nutrient absorption. They also produce compounds like short-chain fatty acids that support gut health and barrier function.

For those with malabsorption, especially during periods of active symptoms, it is often best to reduce high-insoluble fiber intake (raw vegetables, whole grains). Instead, focus on soluble fiber sources like bananas and oatmeal, and well-cooked, skinless vegetables. Increase fiber slowly as symptoms improve.

Nutrient deficiencies are common with malabsorption, so supplements are often necessary to correct them. A doctor may recommend specific supplements, such as fat-soluble vitamins (A, D, E, K), B12, iron, and calcium, in easily absorbable forms.

For many with malabsorption, cooked, well-steamed, or pureed vegetables are easier to digest than raw ones. The cooking process breaks down fibers, making nutrients more accessible and reducing digestive stress.
