protein intake and kidney function


While the rate of muscle protein synthesis is at its highest for the first 20-25 grams of protein in a meal, we can utilize more (3). The effect of dietary protein on kidney function expressed by creatinine clearance was studied in healthy subjects following a "normal" unrestricted protein diet and compared with a group of vegetarians maintained on a long-term low-protein diet. 2007 Sep 26;4:8. doi: 10.1186/1550-2783-4-8. This belief primarily comes from the interaction and relationship between protein and the kidneys. A high-protein diet may worsen kidney function in people with kidney disease because your body may have trouble eliminating all the waste products of protein metabolism. HHS That’s true – if you eat protein-dense food (i.e. Protein is fine – but eating only protein would be a miserable diet for sure! As a result, the safety of habitually consuming dietary protein in excess of … Overall, the study’s position is that there is no conclusive evidence to suggest that high protein diets cause harm. Suzy 10 years ago . These results suggest that, in contrast with the important therapeutic effect of low-protein intake on the progressive deterioration of kidney function in diseased kidneys, such a diet does not significantly affect kidney function with "normal aging" in healthy subjects. But from clinical trials, we don’t know what that amount is – the data suggests up to 1g per lb of body weight is very benign. But there are also associations with better health in others (7, 8). NIH Here are some of the primary roles of protein in our body (1); Except for isolated fats and sugars, almost every food contains protein. UPDATED N/A … Some research claims too much protein can increase kidney stones, while others show no connection. Patients with a daily total protein intake of ≥1.20 compared with <0.80 g/kg ideal body weight had a two-fold greater rate of annual kidney function decline of −1.60 versus −0.84 mL/min/1.73 m2. Compared with higher carbohydrate diets, there is no adverse effect from low carb, high protein diets. The four studies mentioned in this article also consider all different people. Dietary protein intake can modulate renal function [ 1] and its role in renal disease has spawned an ongoing debate in the literature. But would that mean it is the protein content causing the harm? Recent trends in weight loss diets have led to a substantial increase in protein intake by individuals. This was the argument given when When using time-averaged amount of protein intake, rapid eGFR decline was higher in the group with highest protein intake (OR for Q4 compared to Q1: 2.66, 95%CI: 1.37-5.17, P=0.01). But overall, the data suggest that there would be no harm from consuming around 1 gram protein per pound of body weight. For instance, someone eating more fast food hamburgers would likely be eating more protein. In short, this study showed very high protein diets don’t adversely affect kidney health in individuals with abdominal obesity. After a 12-month period, there were no indications that the participants on higher protein diets had experienced any adverse effects on kidney function. However, just because we can’t prove high protein intake causes problems doesn’t mean we should consume ad lib amounts of protein. However, some studies suggest that keeping protein intake at a moderate level may help people with pre-existing kidney disease (12, 13). Chronic kidney disease (CKD) patients should consider adding more plant-based proteins such as beans and tofu to their diet. Avocados are often touted for their many nutritious qualities, including their heart-healthy … Pollock CA, Ibels LS, Zhu FY, Warnant M, Caterson RJ, Waugh DA, Mahony JF. There's mixed research on high-protein drinks and kidneys. However, if you still wish to opt for a high-protein diet, make sure to first check your kidney function. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/.  |  Washington, DC: The National Academies Press. This food safety organization published their findings on protein intake and kidney health in 2012. Are high-protein, vegetable-based diets safe for kidney function? First of all, protein is an essential macronutrient, and our health would quickly fail without it. There is evidence that higher protein consumption can lead to a range of positive effects. Once you hit a certain amount, it becomes unappealing.  |  Suggested Citation:"7 Effects of Protein Intake on Renal Function and on the Development of Renal Disease." Furthermore, all participants had higher plasma amino acid concentrations than those who consumed the 40-gram serving (4). J Am Soc Nephrol. Counseling sessions with a registered dietitian are recommended for planning and monitoring a low- or high-protein diet. One of the most thorough research papers on the topic is a systematic review of 64 prior studies that passed quality checks. Both groups had similar kidney function and displayed the same rate of progressive deterioration in renal function with age. None found any evidence of causation, and no adverse changes in kidney health. With regard to kidney function, present results agree with results of the Nurses' Health study that found an association of low protein intake with lesser decline of kidney function over time only in the subgroup with original kidney function in the range of 55–80 mL/minute × 1.73 m 2. Notably, this level of protein intake is 3-4 times higher than the current dietary guideline’s recommended daily allowance (RDA) (15). Incorporate loads of fresh fruits and vegetables in your diet, it helps your kidneys. Protein intake has been directly associated with kidney growth and function in animal and human observational studies. Key Point: A protein intake 3-4 times greater than the RDA causes no harm or adverse changes to health markers over 12 months. Higher Protein Intake Is Not Associated With Decreased Kidney Function in Pre-Diabetic Older Adults Following a One-Year Intervention (2018) I can’t count the number of times I’ve heard people worried about it. Renal function and protein intake is something that the meat critics love to present, but here again you have more info that illustrates that this is NOT an issue. If waste products build up in our body, they become toxic, and so the kidneys play a crucial role in removing these products. This randomized controlled study investigated if low carb (and high protein) diets have any risks to kidney function (17). In recent years, there have been several studies that investigated this issue, and they all show no link between protein intake and adverse markers of kidney health. CKD patient should have low protein, phosphate, sodium, potassium, and calcium in their diet. Markedly, the EFSA deemed that there is insufficient evidence available to justify an upper level of protein intake for optimal kidney function. Why does no one eat moderately any more? In short, the study found no detrimental effects of a high protein diet on kidney health and no negative changes to any health markers. Wagner EA, Falciglia GA, Amlal H, Levin L, Soleimani M. J Am Diet Assoc. Effect of chronic dietary protein intake on the renal function in healthy subjects. Specifically, the National Kidney Foundation recommends an intake of 0.8 g protein per kg of body weight per day for people with diabetes who have chronic kidney disease in “an effort to reduce albuminuria and stabilize kidney function.” Drink plenty of water. Last Updated on November 13, 2019 by Michael Joseph. Summary: Dietary protein intake and renal function. The evidence pointed to the body actually adapting to the higher protein in the diet. Throughout the study, lab tests demonstrated increased serum urea and urea excretion were consistent with increased protein intake. In the non-RHF group, there was no difference for rapid kidney function decline between the different quartiles. This can be done by measuring your blood creatinine (to estimate how much blood is being filtered by the kidneys) and by a urine sample (to check whether there is protein in the urine). A High Protein Diet Has No Harmful Effects: A One-Year Crossover Study in Resistance-Trained Males (2016). This site needs JavaScript to work properly. NLM While eating animal protein was previously associated with a negative health effect on these patients, a new study shows that eating plant proteins can actually improve their health – and lower their mortality rate. Many myths and controversies exist in the field of nutrition, and they often depend on a personal interpretation of observational studies. In this randomized controlled study, Jose Antonio of the International Society of Sports Nutrition (ISSN) led research into potential harms of a high-protein diet in resistance-trained individuals (14). Avocados. Soy and protein are their gods. chicken breast) it’s definitely hard to overeat. Thanks! First of all, there are associations between high protein intake and health problems in some studies (5, 6). The too much protein idea seems to be incredibly common. In this study, 355 pre-diabetic men and women were split into following two different dietary systems (16); The higher protein diet worked out at 1.6 grams protein per kilogram of body weight. In population studies, CKD etiology is often uncertain. Chronic kidney disease (CKD) has a prevalence of approximately 13% and is most frequently caused by diabetes and hypertension. In other words; 30 grams of protein in one meal is not the “limit.”. International Society of Sports Nutrition position stand: protein and exercise. In other words, there is currently no such thing as “too much protein” regarding negatively impacting renal function. Intervention studies indicate that high protein intake induces short-term up-regulation of GFR and that low protein intake may slow down the GFR decline in chronic kidney disease [2, 3]. Of course, we should still be sensible, and we shouldn’t overeat protein just for the sake of it. However, higher protein diets don’t adversely affect kidney function in healthy people. As our body metabolizes protein, the process generates various nitrogenous waste products such as urea, uric acid, creatinine, and hippuric acid (10). I have friends who have given up all food except protein bars, shakes,and chicken breasts to stay thin. If you want to follow a high-protein diet, choose your protein wisely. While animal foods tend to be the best (most bioavailable) sources of protein, a few plant foods can be high in the macronutrient too (2). Dietary Protein Intake and Renal Function. However, all the others (including the systematic review of 64 studies) were on both males and females. CKD patient should keep blood pressure in control, for a healthy kidney. These waste products need filtering out of the body for excretion, and this responsibility belongs to our kidneys. Possibly, but at what amount remains to be seen. J Am Diet Assoc. On the negative side, this systematic review did find an association between kidney function decline and high protein intake in people with kidney disease. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. This amount accounts for around 25% of all cardiac output, which shows the importance of the organ (11). In this particular study, the 70-gram serving of beef protein led to a significantly greater anabolic response. Short-term exposure to a high-protein diet differentially affects glomerular filtration rate but not Acid-base balance in older compared to younger adults. At a certain stage, the intake vs. benefits ratio will drop, and eating more will simply become counter-intuitive. A review of studies of high protein dietary intake and renal function found no link between developing renal disease in healthy people. Interestingly, there was even a slight indication of improved kidney function with increasing protein intake. 2007 Apr;107(4):644-50. doi: 10.1016/j.jada.2007.01.002. Among the notable points from this study was the findings of the European Food Safety Authority (EFSA). Protein and the stages of CKD This is the first and the largest cohort of older state-of-the-art drug-treated post-MI patients showing that high-protein intake is associated with accelerated kidney function decline. After a period of 12-months, there were no changes in either group to serum creatinine or glomerular filtration rate (markers of kidney health). Involved in many biological processes such as hormone and enzyme production, and it plays a part in immune response. These results suggest that, in contrast with the important therapeutic effect of low-protein intake on the progressive deterioration of kidney function in diseased kidneys, such a diet does not significantly affect kidney function with "normal aging" in healthy subjects. This particular paper found that links between a high-protein diet and cancer, cardiovascular problems, and all-cause mortality are all inconclusive (9). Reply. 2. This means your kidneys do not have to work as hard to remove the extra waste and fluid. This systematic review analyzed the existing literature on protein intake and a range of different health conditions (9). We will now take a look at four relevant randomized controlled trials and systematic reviews. This task requires a lot of hard work, which is quite normal for the kidneys; they receive and process approximately 1.2 liters of blood per minute. In this article, we will examine whether high protein diets are safe by looking at the best available evidence. Analyses indicated that the total amount of protein intake per day was inversely associated with the annual rate of kidney function decline. Compared with women with the lowest protein intake, women who consumed the greatest amounts of protein were more than three times as likely to have a significant decline in kidney function. However, the researchers do stress that they can’t rule out high protein intake affecting kidney function in the long term since this research doesn’t yet exist. Clipboard, Search History, and several other advanced features are temporarily unavailable. Maybe it is possible for an excessive amount of protein to cause problems, there comes a point when “too much” of anything is bad. Dietary protein intake for patients with CKD is based on the stage of kidney disease, nutrition status and body size. Observational studies at the level of the general population reported conflicting data about the association of protein intake with GFR estimates derived from serum creatinine (S-cr) and oth… The resistance-trained study was of male only? The amount at which this would occur likely depends on a combination of overall diet/lifestyle and physical activity levels. Diets that are very high in protein cause kidney problems. In other words; it is difficult to ascertain whether it was the protein (or side servings of french fries and soda that many eat) that cause the problems. In truth, no universal limit determines the exact amount of protein everyone can digest. Among these, those with the highest protein density are predominantly animal foods. The kidneys need water to help in their function of filtering and when you are dehydrated, filtering gets hampered. There is evidence that links protein supplementation with decreased renal, or kidney, function. One particular study that shows evidence for this was a randomized study investigating the effect of a 40-gram beef protein meal versus a 70-gram beef protein meal on protein synthesis in human participants. At the very least, it seems like protein isn’t something to be stressed about. Yes correct, the resistance-trained study only had male participants. “The higher the intake, the faster the decline,” ​it concluded. No one knows the long term effects of these diets. Studies show that protein intake at up to 35% of total energy intake has no adverse effect on people with healthy kidneys. Protein increases lean body mass, which is associated with better metabolic health (, As the most satiating macronutrient calorie-for-calorie, protein reduces appetite and food cravings, and therefore leads to healthier eating behaviors (, Protein is important for bone health and protecting against loss of bone mass. Many studies suggest that limiting the amount of protein and including more plant-based foods in the diet may help slow the loss of kidney function. It is easy to hear claims that too much protein damages our kidneys. es (i.e., hypertension). COVID-19 is an emerging, rapidly evolving situation. A total protein test can detect normal or abnormal protein levels, which can help diagnose medical conditions, such as kidney and liver diseases. It’s nice to see someone who follows sensible advice and actually does their research! This is particularly true as we age and the rate of muscle protein synthesis falls (. If we did eat too much protein, whatever that amount might be for each individual, then will we have problems? The protein addicts are as bad as any other radical diet group. As a result, many people assume that higher protein intake leads to a higher kidney workload, and the extra demand causes kidney strain. Consuming more protein than this would likely be unnecessary for the majority of people. In each of these papers, the researchers were trying to establish whether too much dietary protein can damage the kidneys, and what risks high protein diets may have. Protein supply can vary widely during the first months of life, thus promoting different kidney growth patterns and possibly affecting kidney and cardiovascular health in the long term.
