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, at least not from a nutritional standpoint.

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 this is only true for someone who is not getting protein from a variety of sources.

That is, most people already get all of the essential amino acids they need.

In fact, less than 1% of individuals aged 19 years and older do not meet the Estimated Average Requirements for essential amino acids (J Nutr, 2023).

In case you forgot, amino acids are the building blocks of protein and your body can make most, but not all 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 are complete, meaning they contain all the essential amino acids, whereas others are not, this is not a meaningful difference for 99% of people.

This explains why research shows plant-based protein supports muscle mass and body composition improvements just as well as whey protein (Int J Environ Res Public Health, 2021).

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

They are also easy to break down and absorb.

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 protein supplement on the planet.

Unlike other protein sources, which must be stripped of fats, carbs, fiber, etc. before they can be used as protein supplements, 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, which removes enzymes, fiber, and other natural digestive aids that help you digest the protein.

Did you know that regularly eating protein concentrates and isolates can disrupt your gut microbiome (Nutrients, 2018) and cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024)?

Egg whites, on the other hand, will not cause digestive issues, even if you have a sensitive stomach.

This is why Egg White Protein Powder is good for you!

What Is the Healthiest Egg White Protein Powder?

Not all egg white protein powders are created equal.

Unfortunately, many egg white protein powders contain ingredients known to cause painful side effects and long term health problems.

Among these ingredients are food additives.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other ultra-processed additives can not only upset your stomach, but 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 causes a cascade of problems, including intestinal permeability, systemic inflammation, impaired nutrient absorption, and reduced short-chain fatty acid (SCFA) production.

⚠️ 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.
