Clean Protein Powder

What Is “Clean” Protein Powder?

Protein powder is a concentrated form of dietary protein in powder form.

It can be made from virtually any high protein food, including milk, peas, and eggs.

In the context of nutrition, “clean” refers to supplements, foods, beverages that are as close to nature as possible, meaning they have undergone little to no processing.

A banana is a perfect example of clean food; you cannot get closer to nature than a banana.

Coca Cola, on the other hand, is not clean; it cannot be found in nature, nor does it look remotely like anything that can.

It follows that if you want to “eat clean,” avoid packaged and processed foods, and focus on cooking your meals from scratch using fresh ingredients.

The more of your plate that consists of foods you could gather, grow, harvest, or hunt, the better.

Now, I know what you are thinking: If packaged and processed foods are not clean, then is there no such thing as clean protein supplement?

This is a fair question because protein powder is undeniably a packaged, processed food.

In fact, most protein powders are technically ultra-processed foods, which means they are by no means “clean.”

Protein sources like milk and peas do not contain enough protein by weight to be used as a protein supplement.

They therefore must be stripped of their fats, carbs, fiber etc.

And the amount of mechanical and chemical intervention required to do this makes them an ultra-processed food.

To know if your protein powder contains ultra-processed protein sources, look for “concentrate” or “isolate” in the ingredient list.

In case you were wondering, all whey, pea, soy, and beef protein powders are ultra-processed and therefore not clean.

The only types of protein powder that qualify as clean are Egg White Protein Powders and Nut-Based Protein Powders.

But the protein source is not the only thing you have to take into consideration when looking for a protein powder.

What Is the Best Clean Protein Powder?

First of all, be wary of brands that overtly claim to make clean protein supplements.

If a company labels its products as clean, it probably has something to hide.

Take, for example, the company Clean Simple Eats.

Its best-selling protein powder contains xylitol (a sugar alcohol), natural flavors (which contain added solvents, preservatives, etc.), and xanthan gum (a thickener).

None of these ingredients are clean, not even close.

Clean protein powder must be made with a short list of simple ingredients; it cannot contain gums, lecithin, flavors, or any other food additives.

⚠️ 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 a food additive.

What Is the Best Clean Vegan Protein Powder?

Believe it or not, vegan protein powders tend to be the worst when it comes to using clean ingredients.

Because plant protein concentrates and isolates are so chalky and hard to mix, vegan protein powder companies tend to add lots of emulsifiers and thickeners.

If you want a clean vegan protein powder, you must read the ingredient list closely.

And do not let words like “organic” and “plant-based” lull you into a false sense of security.

Just because a product is organic does not mean that it is good for you.

What Are the Advantages of Clean Protein Powder?

While using a clean protein supplement could benefit most people, it is especially beneficial for:

• Pregnant and Nursing Women: Pregnant and nursing women require extra protein to support the growth and development of their babies. Clean protein supplements can help them safely meet their elevated protein needs.
• Individuals with Digestive Issues: Clean protein powders can help people with digestive issues such as irritable bowel syndrome (IBS) meet their daily protein needs without causing side effects.
• Kids and Seniors: Kids and seniors who need help filling in gaps in their diets can benefit from a clean protein powder, which provides what they need and nothing they do not.

In short, clean protein powder is a powerful nutritional tool that can help a wide range of people safely and conveniently meet their protein needs.
