Is protein powder paleo?
Finding a protein powder for the paleo diet is hard because 99.99% of protein powders are not paleo. For starters, most protein powders are made with either whey, soy, or pea protein, none of which are paleo. Whey protein comes from milk, and soy and pea protein come from legumes. Milk and legumes are not allowed on the paleo diet.
The real reason why most protein powders are not technically paleo, however, has nothing to do with the type of protein. Save for a handful exceptions, most protein powders are not paleo because they are made with protein concentrates or isolates. Protein sources like these heavily-processed ingredients stripped of everything but the protein. They were absolutely not on the menu during the Paleolithic era, and cannot be part of a Paleo diet.
Another reason why most protein powders are not compatible with the paleo diet is that they contain added ingredients like emulsifiers, thickeners, flavors, and sweeteners. Food additives like these, including natural flavors and natural sweeteners like stevia, are not paleo.
Here is a list of the most common food additives in protein powder:
acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors*, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol
