I have heard rumors about how too high of a protein intake can affect your kidney adversely. Now, I do not completely buy into the whole argument but I am sure people can get overdose on protein (just as you can get overdose on anything else).

What then, is the sign of you eating too much protein? Breath smell? Urine color? Skin color? etc etc..
Is it a genuine concern (on the kidney or bones for example)? What are some sickness you can get from too much protein? kidney stones?

I just want to know a bit more about this issue because I've been engaging myself in a high protein diet (~150g for a 112lbs person) and I'm not sure how (un)healthy it is. =) Just want to get some feedback. Thanks!

You're over 1.25g per pound which is still good. if you don't have any kidney problems you won't have any issues. Remember protein has calories just like the other macros (4 calories). So, the only thing I see is you could gain weight if you go over your maintenance.

I have heard of people who have had kidney stones because of too much protein yes. If your only 112 lbs I dont see why you would need 150g's of protein. If your doing killer workouts everyday involving alot of lifting maybe I would consider it. I guess it all depends on what/how your body is handling it, your diet, and what your workouts are like as to where really your protein intake is. There are resources out there to tell you what percentage you should be shooting for and perhaps you should consult those. If you do however decide to keep your protein up in the 150's, you should be drinking alot of water too. Also, if your protein intake is high and your not putting in the workouts, Im to the understanding that a surplus of protein will turn to fat. I never have checked that out to be sure, so that may be something you'd want to research also. Im sure someone in MFP will know better than I. good luck =)

Bodybuilders have heaps of protein without any issues. It is when you already have damaged kidneys that you have to limit protein intake. Some have 1g protein per pound of lean muscle. make sure to drink a lot of water.

A surplus of calories will be stored as fat. Higher protein diet is very satiating.

I take high proteins for a few reasons:

1. I lift 3 times a week
2. I love protein (who doesn't?). Steak tastes great.
3. If I eat rice/pasta/carbs during lunch, I get food coma. That's why I resort to veggies + meat
4. I love EGGGS, so I eat about 3 a day.

I drink quite a lot of water (3 liters a day?). In the past, a lot of water = clear urine. These days, I do not experience that. Hence I was thinking if somehow I'm overworking my kidney or if I overshoot on my protein intake.

You're perfectly fine. Keep up the good work!

Like fit said, you are good... I take 1-1.25g or protein per lbs of body weight.. I do this to preserve muscle while cutting!!
About 180grams/day for me!!

You can get increased chance of gout from taking too much protein due to a build up of uric acid.

The only way to know for sure if you're getting renal (kidney) problems from your diet is to visit your doctor and have a little blood drawn. He/she can check your GFR, which is glomular filtration rate, a hallmark sign of renal function. If <60 (non African-American) then you *may have a problem. Over 60 (non African-American) is fine. The values are different for African Americans due to genetic variation (I think is the cause, not 100% sure on that)
February 21, 2012 4:53 AM
So as long as I keep to 1.5g x weight in lbs, I should not be concerned and just enjoy my food? ^__^
But ya .. everything is pointing toward a blood check. All those cholesterol myth about consuming eggs, I should get that checked out too via blood test!
February 21, 2012 4:59 AM
just make sure you drink a lot of water to avoid potential kidney stones

From everything I've read/heard, protein only causes problems with PRE-EXISTING kidney issues - it doesn't CAUSE kidney issues.

Does anyone know if protein is a water soluble nutrient? i.e. do you pee out the excess that your body doesn't absorb?

Uric acid is formed from high fructose corn syrup aswell.

One reason--and the basic reason--there is much debate over high protein diets and the effect on renal function has to do with the make-up of a protein. CHON (Carbon Hydrogen Oxygen & Nitrogen). Nitrogen particles are HUGE compared to the other 3 in genetic make-up and is ONLY filtered out of the body via the kidneys. Over time, elevated protein diets CAN impair renal function, especially depending on the source of the the protein. Increased protein consumption leads to hyperfiltration - a state in which the kidney faces increased pressure in order to filter and remove waste from the body. Over the long term, hyperfiltration may lead to kidney damage.

If you have questions concerning your renal health, it is best to have blood work drawn, not just to check the GFR, but also your Creatnine and BUN levels. These 3 labs will give you a pretty good analysis of how your kidneys are functioning.

Should Creatine and BUN be low or high then?

Its absolute rubbish. I challange you to find ONE study showing someone with health kidneys is effected by high levels of protein.

Furthermore, read this:

Do regular high protein diets have potential health risks on kidney function in athletes?

Abstract


Excess protein and amino acid intake have been recognized as hazardous potential implications for kidney function, leading to progressive impairment of this organ. It has been suggested in the literature, without clear evidence, that high protein intake by athletes has no harmful consequences on renal function. This study investigated body-builders (BB) and other well-trained athletes (OA) with high and medium protein intake, respectively, in order to shed light on this issue. The athletes underwent a 7-day nutrition record analysis as well as blood sample and urine collection to determine the potential renal consequences of a high protein intake. The data revealed that despite higher plasma concentration of uric acid and calcium, Group BB had renal clearances of creatinine, urea, and albumin that were within the normal range. The nitrogen balance for both groups became positive when daily protein intake exceeded 1.26 g.kg but there were no correlations between protein intake and creatinine clearance, albumin excretion rate, and calcium excretion rate. To conclude, it appears that protein intake under 2. 8 g.kgdoes not impair renal function in well-trained athletes as indicated by the measures of renal function used in this study


PMID: 10722779 [PubMed - indexed for MEDLINE]


Test subjects used up to 2.8g per kg of body weight. Some people then go on about osteoporesos caused by high protein and so on, again, shown not to be true -


They concluded that a protective effect of high-casein diet against CsA-induced proximal tubular damage was observed in Sprague–Dawley rats. Lacroix et al. studied the effects of a very-high-protein diet in rats over a period of 6 months. Forty eight Wistar rats received either a normal-protein diet (14% protein) or a very-high-protein diet (50% protein). No nephrocalcinosis, no area of collagenous sclerosis, and no hypercellularity were detectable. Also, endothelial and mesangial cells were normal and so were surrounding tubules.

Most of us that are serious about weightlifting have always consumed around 1g of protein per lb of body weight and haven't had any problems. Cheap protein shakes can give you gas! I learned that the hard way. Keep it up, you are doing fine.
February 23, 2012 4:30 AM
If you are taking a daily multivitamin, it could easily give you bright yellow pee! Its really annoying!

Hey gang! I'm lookin for some info. I just started a high protein diet this week. I'm following the plan that's on men's health website. After logging my intake for the day my calorie intake was 2,024 calories. Broken down I had 51% from protein(259g), 34% from carbs and 15% from fat. I'm 5'9'' and weigh 193 pounds and I'm trying to lose my beer guy and put on muscle. I exercise 4 times a week plus work in construction so I move around all day at work. I have no clue if 50% of my calories coming from protein is good or bad for my situation. I felt fine all day, and not once got hungry or a craving. So, am I good? Or should I cut back a bit on the protein? Thanks a million for any feedback!

Depends, are you consuming 3000 calories or 1200. With 3000 calories your consuming 325g's of protein and at 1200 your consuming 150g's and that's why relying on percentages is not a good rule of thumb. The suggested protein requirements are around 1g of protein for every lb of lean body mass and lets say you have 25% body fat that would mean that you have about 145lbs of lean mass, therefore consuming in and around 150 would be recommended, the other macro's you would adjust from there. Generally fat is about .40g's per lb of lean mass and the rest in carbs, but this can be adjusted depending on your lifestyle............more active, the higher the carbs, generally speaking.

It is very hard for someone who has no pre-existing kidney issues OR who is not on medication that can make protein build in the kidneys to get enough protein in their diets to cause issues. At one point I did personally have to watch my protein intake due to a medication I was on, but even then I had no issues. So honestly, I wouldn't even worry about it (especially at the levels you have said you eat).
