Meal Replacement Shakes for IBD

Are Meal Replacement Shakes Good for IBD?

Yes, meal replacement shakes can be beneficial for some people with IBD.

IBD is an inflammatory condition that affects the gastrointestinal tract.

There are two main types: Crohn’s disease and ulcerative colitis.

IBD is characterized by periods of inflammation called flares and periods of remission when symptoms improve.

Common symptoms include stomach pain, diarrhea, and weight loss.

The exact cause of IBD is not fully understood, but it is likely a combination of genetic and environmental factors (N Engl J Med, 2020).

Although there is no cure for IBD, various treatments can help manage symptoms and control inflammation.

These treatments might include lifestyle and dietary changes.

Some people with active IBD struggle to meet their nutritional needs (AGA, 2024).

This happens for a number of reasons, including decreased appetite, reduced food intake due to digestive issues, and/or nutrient malabsorption.

For these individuals, particularly those who have experienced weight loss, individualized dietary counseling is usually recommended.

In some cases, the focus is on protein optimization – 1.2-1.5 grams per kilogram of bodyweight per day during active disease and ~1 g/kg/day during periods of remission (Lancet Gastroenterol Hepatol, 2023)

It follows that a high protein meal replacement, individualized to the patient with attention to nutritional balance, could be used to provide nutritional support.

During a flare-up, a liquid meal might also be the only food some IBD patients can tolerate.

That said, the benefit of meal replacements in IBD depends heavily on the clinical context, the specific formulation, and how they are used.

Moreover, not all meal replacements are created equal.

What Are the Best Meal Replacement Shakes for IBD?

Many meal replacements contain ingredients that might cause painful symptoms for someone with IBD, and might even contribute to the development of the disease.

These problematic ingredients include food additives, dairy-based proteins, and protein concentrates and isolates.

It is important to note that it is advised to limit fiber intake during an active flare, so avoiding high fiber ingredients might also be good idea (Nutrients, 2022)

🚫 Avoid Food Additives

Many people with gut issues report that emulsifiers, thickeners, artificial sweeteners, and other ultra-processed additives upset their stomachs.

Regularly consuming certain additives can also alter the composition and function of your gut microbiome – the collection of microorganisms living in your gut (North Clin Istanb, 2020).

These shifts, known as gut dysbiosis, have been linked to the development of both Crohn’s disease and ulcerative colitis (Int J Mol Sci, 2022).

Research shows that an imbalanced gut microbiome weakens your intestinal barrier, which can cause inflammatory damage to your digestive system (Front Microbiol, 2019).

It is important to note that although preliminary research linking gut dysbiosis to IBD is compelling, there is no established causal relationship.

⚠️ Here is a list of the most common food additives in meal replacements:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you cannot find it in nature or make it at home, it is probably a food additive.

🚫 Avoid Dairy-Based Proteins

Dairy-based proteins like whey and casein, although not a problem for everyone, might cause digestive issues too.

This is usually because they contain lactose – a sugar many individuals with sensitive stomachs cannot fully digest.

But you might be sensitive to dairy-based proteins even if you are not lactose intolerant.

For starters, the digestion of some caseins releases a bioactive peptide that has been linked to digestive issues (Adv Nutr, 2017).

Casein also forms a gel-like substance in your stomach that slows down digestion (Crit Rev Food Sci Nutr, 2023).

For sensitive individuals, particularly true for those with cow’s milk protein allergy or intolerance, slower digestion might contribute to bloating, constipation, and other side effects.

🚫 Avoid Protein Concentrates and Isolates

You might also want to avoid protein concentrates and isolates.

Most protein supplements are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help you break them down.

You therefore might not digest them in the same way that you do whole foods, which could affect your gut health.

For example, one study shows that regularly consuming protein concentrates and isolates might disrupt your gut microbiome (Nutrients, 2018).

Another study shows that it could cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).

Although further research is needed, individuals with sensitive stomachs can play it safe by choosing protein supplements made from minimally-processed protein sources like egg whites and almonds.

They might be more gut-friendly.
