What is leaky gut? 

Leaky gut syndrome, also known as increased intestinal permeability, is a condition where your intestinal lining becomes damaged or compromised, making it easier for bacteria, toxins, and undigested food particles to pass into your bloodstream. Common symptoms include bloating and diarrhea. Several studies have associated leaky gut syndrome with chronic and autoimmune diseases like type 1 diabetes and celiac disease. 

What exactly causes someone to have a leaky gut is somewhat of a mystery, and there is no recommended treatment. There are several ways to improve symptoms, however, one of which is making changes to your diet.

Many people find that avoiding certain foods, like refined carbohydrates, dairy, caffeine, and artificial sweeteners, help them reduce leaky gut symptoms. They also recommend eating a diet rich in foods that promote the growth of healthy gut bacteria, including fermented foods, fruits, vegetables, and whole grains. It is thought that the health of your gut microbiome – the collection of bacteria and other microorganisms living in your gut – is related to leaky gut syndrome.

Can protein powder cause leaky gut? 

Research suggests that factors such as unhealthy diet, stress, and excessive alcohol, antibiotic, and drug consumption can disrupt the composition of your gut microbiome and the homeostasis of your intestinal barrier function, leading to increased intestinal permeability. In other words, researchers believe that foods that alter your gut microbiome can also alter your intestinal barrier, sometimes in a way that causes leaky gut syndrome. This means that protein powder could very well be part of the problem.

It is worth adding that protein powder tends to have a greater impact on gut health than other types of food because of how often it is consumed. Many people add protein powder to their diet every day, thereby exposing their gut to potentially harmful ingredients on a regular basis. This is why it is so important to choose your protein powder wisely.

Is protein powder good for leaky gut? 

Leaky gut, because it involves damage to your intestinal lining, can affect your ability to absorb nutrients from food. Over time, this can lead to nutritional deficiencies and weight loss. To counteract this, it is important to be mindful of your nutrient intake.

One of the most important nutrients to be mindful of is protein. Dietary proteins are essential for the growth and repair of your mucosal intestinal barrier. Although more research into the role of proteins in intestinal barrier regulation is needed, it is known that some dietary peptides produced by the enzymatic digestion of dietary proteins enhance or protect the intestinal barrier

Exactly how much protein you need will depend on a number of factors, but you should certainly eat at least 0.36 grams per pound of bodyweight per day. For some, especially those with dietary restrictions, eating this much protein can be hard.

This is where protein powder can help. Incorporating a protein powder into your diet is an easy way to fill in nutritional gaps and ensure you meet your daily protein requirements. Not all protein powders are created equal, however. 

What is the best protein powder for leaky gut?

Despite their benefits for someone who needs extra protein, many protein powders are made with ingredients that can cause painful side effects and long term complications for someone with a leaky gut. Among these ingredients are food additives, dairy-based proteins, and protein concentrates and isolates. 

Avoid food additives

Regularly eating emulsifiers, thickeners, sugar substitutes, and other additives can not only upset your stomach, but also alter the composition of your gut microbiome. This can lead to gut dysbiosis, which is associated with the development of leaky gut.

Research shows that a healthy gut microbiome modulates the production and secretion of mucins and stratification of the mucus layers that make up the intestinal mucosal barrier. An unhealthy, or dysbiotic, gut microbiome results in the weakening of this barrier, thereby allowing bacteria and other pathogens to enter your bloodstream. Here is a list of the most common food additives in protein powder:

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, maltodextrin, mono- and diglycerides, ‘natural’ flavors, rice bran extract, rice dextrin, rice hulls, rosemary extract, silica, silicon dioxide, sodium alginate, sodium bicarbonate, soluble corn fiber, soy lecithin, sucralose, sunflower lecithin, tocopherols, tricalcium phosphate, xanthan gum, xylitol, zinc oxide

Avoid dairy-based proteins

Dairy-based proteins like whey and casein, although not an issue for everyone, can cause side effects like bloating and diarrhea. This is in part because they contain lactose, a sugar most adults cannot fully digest.

Avoid protein concentrates and isolates

Most protein powders are made from protein concentrates and isolates, which have been mechanically and or chemically stripped of everything but the protein, including the enzymes, fiber, and other natural digestive aids that help you break them down. As a result, they can cause digestive issues and possibly even disruptions to the gut microbiome

Finding a protein powder free from food additives, dairy-based proteins, and protein concentrates and isolates is hard. In fact, 99% of protein supplements contain one or more of these problematic ingredients. This is why we created drink wholesome.
