Anti-Inflammatory Protein Powder

Does Protein Powder Cause Inflammation?

Your gut is home to the largest population of immune cells in your body, which are constantly challenged to respond to pathogens and maintain intestinal immune homeostasis.

Some of the ingredients used in protein powders can disrupt these regulatory mechanisms, possibly causing chronic inflammation.

In other words, the same persistent activation of the immune system that can occur in your joints (causing inflammatory arthritis) can also take place in your gastrointestinal tract.

And what you eat can play an important role in driving, or in some cases mitigating, these events.

What Is Anti-Inflammatory Protein Powder?

Inflammation is the response of your immune system to pathogens and tissue injury.

Acute is a normal, healthy response that occurs when you get sick or injured.

If you stub your toe, for example, your immune system will dispatch an army of white blood cells to protect the injured tissue, causing visible redness and swelling.

Chronic inflammation, on the other hand, is not normal nor healthy.

It occurs when your immune response lingers, and can cause white blood cells to attack healthy tissues and organs.

For this reason, chronic inflammation has been shown to play a significant role in the pathophysiology of chronic diseases such as cardiovascular disease and type 2 diabetes mellitus.

Fortunately, making changes to your diet is an easy way to reduce chronic inflammation and the risk of chronic disease.

Eating more fruits, vegetables, whole grains, healthy fats, and lean protein, and limiting the consumption of processed foods, red meats, and alcohol is a good place to start.

Some people even choose to prioritize foods with anti-inflammatory properties (food shown to modify the inflammation response).

Although protein powder is not typically considered to be an anti-inflammatory food, it can certainly be part of an anti-inflammatory diet.

Dietary protein itself has been shown to reduce inflammation for certain individuals and certain high protein, plant-based foods have anti-inflammatory properties (Int J Mol Sci, 2023; Curr Protein Pept Sci, 2019).

That said, not all protein powders are created equal.

What Is the Best Anti-Inflammatory Protein Powder?

Any type of protein powder (egg white, pea, whey, etc.) can help you meet your daily protein needs.

In other words, as long as you are eating a balanced diet, there is no advantage to using one type of protein powder over another.

Ingredients do matter, however, especially when it comes to inflammation.

For instance, many protein powders contain ingredients that could cause chronic inflammation, including food additives and protein concentrates and isolates.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other additives can alter the composition of your gut microbiome (the collection of microorganisms living in your gut) (North Clin Istanb, 2019).

This can lead to gut dysbiosis, or an imbalance in gut bacteria, which is a leading driver of inflammation (Microorganisms, 2022; Mucosal Immunol, 2017).

Inflammation occurs because gut dysbiosis damages the intestinal lining, which is tasked with regulating inflammation (Biomed Pharmacother, 2023).

The intestinal lining is a single layer of cells that forms a selective barrier, allowing nutrient absorption while preventing the entry of pathogens and antigens into the blood.

⚠️ Here is a list of the most common food additives in protein supplements:

• 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 an issue for everyone, can cause digestive issues.

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.

This is particularly true for casein protein, which forms a gel-like substance in your stomach that slows down digestion.

🚫 Avoid Protein Concentrates and Isolates

You might also want to avoid ultra-processed 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 your gut break them down.

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

Studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

You should thus look for protein supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
