Egg Protein Is Good for You

Why Is Egg White Protein Powder Good for You?

If you are eating a balanced diet, the type of protein powder you use does not matter nearly as much as meeting your total daily protein needs.

I understand that this might contradict what you have heard, so allow me to explain.

Some people think that certain protein sources (like peas) are inferior to others (like whey) because they contain fewer essential amino acids.

But most people already get all of the essential amino acids they need through a balanced diet.

In fact, one meta-analysis concluded that less than 1% of adults failed to meet the Estimated Average Requirements for essential amino acids (J Nutr, 2023).

In other words, over 99% of people get enough of all the essential amino acids.

Amino acids are the building blocks of protein, and your body can make many of them.

The amino acids your body cannot make are called “essential” amino acids and must come from the food you eat.

While it is true that some protein sources contain all the essential amino acids whereas others do not, this is not a meaningful difference for most people (J Nutr, 2024).

This explains why pea protein supports muscle mass and body composition improvements just as well as whey protein (J Int Soc Sports Nutr, 2015).

For the record, egg whites are a source of complete protein.

They are also relatively easy to break down and absorb compared to most other protein sources.

In fact, egg whites have a protein digestibility-corrected amino acid score (PDCAAS) of 1, which is the highest score possible (J Nutr, 2000).

The real reason Egg White Protein Powder is good for you has nothing to do with amino acids, however.

Egg White Protein Powder is good for you because it is the least-processed, mainstream protein powder.

Unlike other protein sources, which must be stripped of fats, carbs, fiber, etc. before they can be used as protein shakes or powders, egg whites are a whole food.

They are simply pasteurized and dehydrated before you add them to your smoothie.

This means they are spared all of the mechanical and chemical processing that goes into making other protein powders.

This matters because processing almost always removes enzymes, fiber, and other natural digestive aids that help you break the protein down.

In other words, you might not digest protein concentrates and isolates 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 might cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).

Although further research is needed, choosing a minimally-processed protein source like egg whites could be the most gut-friendly choice.

What Is the Healthiest Egg White Protein Powder?

Not all egg white protein powders are created equal.

Unfortunately, some egg white protein powders contain ingredients that are associated with painful side effects and even long-term gut health problems.

Among these ingredients are food additives.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, artificial sweeteners, and other ultra-processed additives can not only upset your stomach, but might also alter the composition and function of your gut microbiome (North Clin Istanb, 2020).

These shifts, known as gut dysbiosis, have been shown to contribute to the development of several chronic diseases (Microb Ecol Health Dis, 2015).

Gut dysbiosis is so problematic because it can cause a cascade of problems, including intestinal permeability, systemic inflammation, impaired nutrient absorption, and reduced short-chain fatty acid (SCFA) production.

So, to choose the healthiest egg white protein powder,I suggest simply avoiding food additives.

⚠️ Here is a list of the most common food additives in protein shakes and powders:

• 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.
