As a former dialysis nurse, I am somewhat reserved and dubious about protein intake; especially HIGH PROTEIN INTAKE. True enough, most reading this are not in renal (kidney) failure. Protein must be moderated for those suffering from renal insufficiency. However, it makes me consider the overly paraded cascade of high protein consumption.
Creatinine is a test used to diagnose renal (kidney) function. It can be increased in those who ingest large amounts of meat. Yes, it is only elevated slightly and can be transient–but my question is this. What happens if it is continually elevated, because that’s the majority of the person’s diet? Can the kidneys keep up with this demand?
Blood, Urea, Nitrogen (BUN) measures the amount of urea and nitrogen in your blood. So what’s that supposed to mean? Well, urea is the end product of PROTEIN metabolism. During a meal, protein breaks down into amino acids. In your liver, these amino acids are catabolized and free ammonia is formed. These molecules combine and form urea, which is deposited into blood, and given over to the kidneys to excrete (rid themselves of). Again, if this is 60-70% (or more) of a person’s diet, now what?

QUESTIONING; NOT DEBATING
I did preface this with my bias. Of course protein diets will help with weight loss. So will smoking. For years women swore by smoking to curb their appetite. Many still do. And while I’m really not trying to compare the two, there is an article which does.
No, I’m not a vegan, nor do I plan to become one. My palate expresses no desire for bean paste or tofu. I love my chicken, ribs, and steak. BUT, this does not represent my primary or elevated intake. Fish? Forget it for me. I hate fish. However, with the advent and subsequent takeoff of high protein diets being touted, it raises questions. Sure there are other sources of protein; never said there weren’t. But HIGH protein with mitigated or very low carb ratio, can and does have consequences. Many of them numerous, and beyond the scope of what’s discussed in this blog. Need a little more convincing? Ok.
What I’ve always taught, both patients and students is this: Be mindful not just of outcome, but of rationale (the “why” and reason behind an action) Rationale for me, must represent all of the following–cause, relationship, and effect. Yes, these diets will cause you to lose weight. Yes, that is your desired outcome. But what of the other components; relationship and effect?
You be the judge.
All for now. Keep up and keep at it.
