Real Food Protein Powder

What Is Real Food Protein Powder?

Whole foods are foods that can be found in nature.

If you cannot harvest, hunt, or gather it, it is not a whole food.

Examples of whole foods include: eggs, fish, fruits, legumes, nuts, seeds, unprocessed meats, vegetables, and whole grains.

Real foods, on the other hand, are just foods made from minimally-processed whole foods.

Minimally-processed means the food has not lost its basic structure and nutritional content.

Peanut butter made with just peanuts is a perfect example of a real food.

Although you cannot find peanut butter in nature, it is very close to nature.

That is, to make peanut butter, all you need to do is roast and grind peanuts.

Corn syrup, on the other hand, is not a real food.

Although it is technically derived from a whole food (corn), it is so processed that it looks nothing like anything you can find in nature.

It follows that real food protein powder must be made from only minimally-processed whole foods.

Very few protein powders can be considered “real food” protein powders.

That is because nearly all protein supplements are made from protein concentrates and isolates, which have been stripped of everything but the protein.

This requires so much mechanical and (often) chemical intervention that it is technically ultra-processing (Food Nutr Res, 2023).

Moreover, most protein powders contain food additives that look nothing like real food.

Among these ingredients are emulsifiers like sunflower lecithin, thickeners like xanthan gum, and most sweeteners and flavorings.

⚠️ 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

Basically, if you could not find an ingredient in nature or make it at home, it should not be in your protein powder.

Why Should I Use Real Food Protein Powder?

Not only can food additives cause digestive issues like bloating, diarrhea, and stomach pain, but they can also 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 has been linked to chronic diseases like obesity, type 1 diabetes, and colorectal cancer (Microorganisms, 2022; J Exp Med, 2019).

Your gut microbiome affects various physiological processes, including immune function and inflammation, so when the balance of bacteria therein is disrupted, it can have a huge impact on your overall health.

Moreover, protein concentrates and isolates have been stripped of the fiber, enzymes, and other natural digestive aids that help you break them down.

Your digestive system therefore does not digest them in the same way that it does whole foods, which can affect everything from satiety to gut health.

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

Individuals with pre-existing digestive issues should thus look for protein supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
