The Myth of Protein Supplements
As my readers know, I have a real problem with 'magical' supplements that cure ills and fix problems. By and large, when one looks closely, those claims tend to be highly overstated - if not downright false. Most of my columns are related to weight-loss and fat-burning supplements, but it appears that protein supplements share much of the same mythos.
According to the Live Science article Protein Supplement Myth Revealed by Body of Work, "a growing body of research shows you don't need protein supplementation unless you are a professional-level athlete in intense training or perhaps gravely ill from starvation or a wasting disease." Even under those conditions, adding large amounts of protein may well do more harm than good. Each person's situation should be evaluated by a medical professional and regularly monitored.
We are familiar with muscle-wasting disease. End-stage liver disease is such a condition, and during Mark's illness we watched as he lost muscle-mass. However, the worst thing we could have done was increase his protein intake. Protein is processed / broken down in the liver and, with a damaged liver, the protein is not properly metabolized, leading to build-up of ammonia levels in the bloodstream. A contributing factor to a dangerous complication called hepatic encephalopathy.
Excess protein also breaks down into byproducts that are removed through, and may put a strain on, the kidneys. It is considered likely to trigger release of calcium by the bones. Although no indication of short-term problems has been found, there is a long-term risk for kidney damage or osteoporosis. Recent studies indicate that excess protein can cause inflammation and a greater risk of arterial blockage. These are major concerns, especially in the United States where few people actually suffer from a lack of protein in their diet.
The Harvard School of Public Health offers dietary information and guidelines, that show how much protein the body needs every day. It also explains healthy sources, how the body makes proteins from amino acids, and bottom-line recommendations.
Unless you're competing for Mr./Ms. Universe, protein supplements may be, at best, a waste of money and, at worst, a strain on your health.
