Protein Powder for Breakfast

Why Should I Add Protein to My Breakfast?

Adding protein to your breakfast is a great idea for a number of reasons.

First of all, protein is the most satiating (filling) macronutrient.

Eating lots of it at breakfast will therefore make you feel full for longer.

This, in turn, will curb cravings and overeating later in the day.

Adding protein to your breakfast can also help you manage your blood sugar levels.

Many breakfast foods – cereal, fruit, bread, etc. – are high in simple carbohydrates, which can cause blood sugar spikes and crashes.

By adding protein, you will reduce your glycemic response, which not only helps with weight management, but also decreases your risk of many chronic diseases (N Engl J Med, 2020).

Finally, eating more protein, in combination with lifting weights, can help you build and maintain muscle mass.

Having more muscle improves strength and bone health; it also increases metabolism because it takes more energy (calories) to maintain muscle than fat.

In short, a high protein breakfast is a great way to start your day and support your overall health.

Why Should I Add Protein Powder to My Breakfast?

You should try to get as much protein as you can from foods like dairy, eggs, and meat, but people with dietary restrictions and/or busy schedules may have a hard time doing so.

This is where protein powder can help.

Adding a scoop of protein powder to your breakfast is a quick and easy way to increase your protein intake.

It can be incorporated into smoothies, oatmeal, yogurt, and even baked goods.

And note that if you are short on time, protein powder can be mixed with just milk or water and taken on-the-go.

All that said, not all protein powders are created equal.

What is the Best Protein Powder for Breakfast?

As long as you are eating a balanced diet, the type of protein you add to your breakfast does not matter.

That is, the nutritional differences between whey, pea, and egg white proteins are negligible for most people.

Ingredients do matter, however.

Many protein powders are made from ingredients known to cause painful side effects and even long-term health problems.

Among these ingredients are food additives, dairy-based proteins, and protein concentrates and isolates.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other additives can not only upset your stomach, but also alter the composition of your gut microbiome (North Clin Istanb, 2019).

This can lead to gut dysbiosis, which contributes to a wide range of chronic diseases, including obesity, type 1 diabetes, and colorectal cancer (J Exp Med, 2019).

⚠️ 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 too.

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.
