When buying protein powder, one additive to avoid in particular is artificial sweeteners. Artificial sweeteners are among the most harmful food additives in the long term as they alter the composition of your gut microbiota. This can lead to serious, chronic GI problems, widespread inflammation, and permanent damage to the gut microbiome.
Some sweeteners, especially sugar alcohols like xylitol, are poorly absorbed by the gut, meaning they feed your hungry gut bacteria. They can also cause diarrhea because they draw water into your intestines. Now you finally have something to blame for those post-protein shake trips to the bathroom!
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
When it comes to identifying food additives, go with your gut. 😉 As a rule of thumb, additives are ingredients that you cannot pronounce. Food additives are not the only thing to avoid when buying protein powder, however. There are several other ingredients that can upset your stomach.
