When used responsibly in conjunction with a healthy diet, whey protein can be a beneficial supplement. However, whey protein can have some risks for individuals in certain situations. Therefore, you should consult with your doctor before beginning a whey protein supplementation regimen.
Appetite Loss
Since whey protein is a fairly nutrient-dense and filling food, consuming it may diminish your appetite. While this can be beneficial for helping you lose weight, it can potentially lead to low levels of vitamins, minerals and other essential nutrients for your body. Therefore, regardless of your protein intake, you should be careful that your diet includes plenty of fruits, vegetables and other nutritious foods.
Lactose Intolerance
Whey protein in nearly any form includes lactose. While many people can consume lactose normally without any problems, those who are lactose intolerant may find that whey causes gastrointestinal side effects. Bloating, cramping, and abdominal pain are all common side effects for lactose intolerant individuals, according to the Mayo Clinic website.
Kidney Problems
Kidney problems are the most commonly mentioned concerns regarding whey protein intake. Although individuals who have normal, healthy kidneys should have no difficulty processing whey protein, protein consumption can be problematic for individuals who have preexisting kidney problems. Proteinuria, which often accompanies chronic kidney disease, is characterized by unusual protein levels in the urine. If you have this condition, your doctor will likely recommend that you avoid whey protein consumption.
Expense
Whey protein can cost from $25 to $40, or even more, per two pound jar. For individuals who consume whey protein regularly, the cost for these supplements can become significant. Although this isn't necessarily a reason to avoid using whey protein in all situations, it's a factor that you should consider before beginning a whey protein supplementation regimen.
