Drink Wholesome is the best SIBO-friendly protein powder.

What is SIBO?

Small intestinal bacterial overgrowth (SIBO) occurs when there is an overgrowth of bacteria in the small intestine, particularly of types of bacteria that normally grow in other parts of the gut. This overgrowth causes stomach pain and diarrhea, and in severe cases can lead to malnutrition and weight loss. 

SIBO is associated with several chronic conditions and can be a complication of abdominal surgery. The most common treatment is antibiotics. That said, although antibiotics can decrease the number of bacteria in the small intestine, they will not address the underlying issue that caused SIBO in the first place. This is why antibiotics are often paired with diet changes.

What is the SIBO diet?

There are several key ingredients to a SIBO diet and one of them is protein. Getting enough protein is important because SIBO can impair your ability to absorb nutrients from food. It is therefore important that you eat enough protein, 1-2 grams per kilogram of body weight, per day. 

We recommend that you get as much protein as you can from normal food. This can be challenging for some people, however, which is where protein powder comes in handy. Protein powder is an easy way to boost your intake and ensure that you are meeting your protein goals. It can be added to smoothies, oatmeal, yogurt, and even baking. That said, not all protein powders are good for you.

Avoid dairy.

Dairy-based protein powders can cause side effects like bloating, constipation, cramps, diarrhea, gas, and stomach pain, especially for people with lactose intolerance or irritable bowel syndrome (IBS). Common dairy-based protein powders include casein and whey protein powder, both of which are byproducts of cheese and yogurt production.

Casein and whey protein can also cause acne. Dairy indirectly stimulates insulin production, which regulates sebum production. Sebum, an oily, waxy substance produced by your body’s sebaceous glands, can clog your pores and cause pimples. Dairy can also hinder your ability to process blood sugar efficiently, which can cause inflammation, especially in your skin. 

If your casein or whey protein powder causes acne or stomach pain, it is time to look for a new protein powder. Fortunately, going dairy-free is easier than ever. Unfortunately, not all dairy-free protein powders are created equal.

“This egg white protein powder is anti-bloat, anti-blood sugar dips, anti-artificial tasting. Seriously the best protein powder I’ve EVER tried (I’ve tried literally every brand on the US market, all types of protein powder too). The product is amazing, period.” – Elizabeth 

Avoid food additives.

Most dairy-free protein powders are full of food additives. Although they are not necessarily bad for you in small quantities, food additives can add up quickly, especially if you drink a protein shake every day. At higher quantities, food additives can cause nasty side effects.

First of all, because food additives are heavily processed and look nothing like real foods, we can have trouble digesting them. As a result, they sit in our guts for longer and ferment. Fermentation produces gas, which can cause bloating, cramps, and stomach pain. Gas also slows colonic transit and can lead to constipation. In the long term, food additives can disrupt regulatory pathways in the intestine and cause the development of inflammatory bowel disease (IBD) and systemic inflammatory disorders.

What exactly are food additives?

As a rule of thumb, food additives are ingredients that you cannot pronounce. Not sure what to look for? Here is a list of the most food common additives in protein powder: 

acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors*, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol *Natural flavors are NOT natural

You may have noticed that this list includes several artificial sweeteners. Some artificial sweeteners may be bad for the stomach because they alter the composition of our gut microbiota, the collection of microorganisms that help us digest food. This can lead to serious stomach pain and widespread inflammation. Other artificial sweeteners, especially sugar alcohols like xylitol, can cause diarrhea because they draw water into the gut. Avoid artificial sweeteners whenever possible.

Avoid protein concentrates and isolates.

Finding an additive-free, dairy-free protein powder is hard. Finding an additive-free, dairy-free protein powder that actually tastes good is next to impossible. Why? Most protein powders, especially plant-based protein powders, are made with protein concentrates and isolates, foods chemically and/or mechanically stripped of everything but the protein. 

Protein concentrates and isolates are listed as “whey protein” and “soy protein” as opposed to “whey” and “soy.” Unlike real foods, they are missing the nutrients – healthy fats, complex carbohydrates, etc. – that make food taste good. If you have ever had a protein shake with a chalky aftertaste, you know exactly what I am talking about. 

Why real foods?

Real foods are foods close to nature. They consist of a single ingredient and have undergone little to no processing. The main real food ingredients in our protein powders are egg whites and chickpeas. Egg whites are simply broken, pasteurized, and dried before becoming protein powder. Chickpeas are simply dried and ground. 

Unlike protein concentrates and isolates, egg whites and chickpeas have a neutral flavor with little to no aftertaste. The egg whites that we use are particularly delicious because they were broken, pasteurized, and dried less than twenty four hours from when they were laid. The result is a flavor without the saltiness or sulfur “eggy” notes typical of eggs.

Protein powder should taste good. Remember, it is just food. If you find yourself choking down your protein shake, you are missing out. Life is too short for protein powders with a chalky aftertaste. Moreover, if consuming protein powder is a chore, it is not sustainable in the long term. A diet is not a six-week affair, it is for life. Think twice before spending your hard-earned dollars on a supplement that tastes bad.

Again, Drink Wholesome is the best SIBO-friendly protein powder because it is made with 100% real foods. Our vegan vanilla protein powder, for example, is made with chickpeas, coconut, vanilla, and monk fruit. Ingredients like these are not only better for you, but also better tasting.
