2 reasons why whey protein powder is bad for you.
Whey protein can cause acne.
Whey protein can upset your stomach.
Why drink wholesome?
Whey protein can cause acne.
Dairy-based proteins like whey and casein can cause acne. Dairy indirectly stimulates insulin production, which regulates sebum production. Sebum, an oily, waxy substance produced by your body’s sebaceous glands, can clog your pores and cause pimples. Dairy can also hinder your ability to process blood sugar efficiently, which can cause inflammation in your skin. Clinical evidence shows that inflammation occurs at all stages of acne development.
Whey protein can upset your stomach.
Dairy-based proteins are also known to cause digestive issues, especially for people with lactose intolerance and irritable bowel syndrome (IBS). Over one in three Americans are lactose intolerant, and the prevalence of IBS is somewhere between 10 and 15 percent in the United States. It follows that you may be lactose intolerant or have IBS and not even know it. Irritable bowel syndrome (IBS) is a poorly understood condition, and it is unclear why dairy triggers symptoms.
Lactose intolerance, on the other hand, is clearly understood. People with lactose intolerance are unable to fully digest lactose, the sugar in dairy. Partially digested food sits in your gut for longer than food should, which gives your gut bacteria more time to eat. As they eat, these bacteria produce gas, which causes bloating and stomach pain. Gas also slows colonic transit (the amount of time it takes food to travel through the colon), and can lead to constipation.
Most whey protein powders are made with protein concentrates and/or isolates, foods stripped of everything but the protein. They are listed on the ingredient list as “pea protein” and “whey protein” as opposed to “peas” and “whey.” I will not go into the details, but protein concentrates and isolates undergo heavy mechanical and chemical processing before becoming protein powder. Sometimes, manufacturers use chemical solvents like hexane to isolate (separate) the protein from the food. This means that what you end up putting into your body looks nothing like real food.
If you think about it, your gut was designed to digest naturally occurring foods, not laboratory formulated imitations, so if you feed it anything but real food, it might get upset. The long term implications of eating processed foods are still not well understood, but more and more research is finding that it can alter the composition of your gut microbiota, and lead to permanent damage to the gut microbiome.
