Although widely preferred by bodybuilders and athletes, the side effects of whey proteins should cause one to pause and reflect before opting to use them in order to increase muscle and body mass. Whey is a watery by-product of cheese full of globular proteins, so it is no wonder about the high energy levels associated with taking it. Whey can be produced in three forms, concentrate, isolate and hydrolysate. The three differ in the amount of proteins they contain and the size of these proteins. Consuming whey proteins excessively has been linked to several health conditions, which should be considered seriously before choosing to purchase whey.
One potential danger associated with the proteins is their effect on the immune system, especially on people allergic to milk proteins. In a bid to defend the body, the system might think the whey to be a pathogen and attack it. It may lead to development of symptoms such as a runny nose or an itchy throat if the affected system is the respiratory or if the allergy affects the integumentary (skin) system, one’s face might swell or they may develop rashes. It is therefore advised that people with milk protein allergies avoid whey products altogether.
In addition, whey has the potential to cause digestive problems, especially to people who are lactose intolerant. They may have problems breaking down the whey products and symptoms such as abdominal cramps, bloated stomach and diarrhea might be manifested, especially when they ingest the whey protein concentrate. Other side effects may include weakened bones as a result of the effect of the amino acids on calcium. The proteins may also have an effect on certain medication, and it is advised that when one is taking pills they exercise great caution in regards to whey products.
