Renal Function Following Long

This randomized controlled study investigated if low carb diets have any risks to kidney function .

68 participants were equally split into two groups, and they were put on one of two diets

  • Diet 1: Very low carbohydrate
  • Diet 2: High carbohydrate diet

As shown, both diets contained a respectable amount of protein, but the VLC diet provided significantly more than current recommendations at 35% of energy.

Full health markers for kidney health were taken before and after the study.

After a period of 12-months, there were no changes in either group to serum creatinine or glomerular filtration rate .

In short, this study showed very high protein diets dont adversely affect kidney health in individuals with abdominal obesity.

Compared with higher carbohydrate diets, there is no adverse effect from low carb, high protein diets.

Signs You Could Be Eating Too Much Protein

Because the phrase “everything in moderation” includes protein too.

In terms of healthy macronutrients, fat and carbs both have their fair share of haters, but protein is pretty much always getting good press. It’s easy to see why: protein is an essential nutrient for strong bones, muscles, skin and pretty much every other part of the body, and it is responsible for thousands of different chemical reactions to make sure your body functions at its best. But that doesn’t mean more is always better.

People often adopt high-protein diets to help lose weight or tone up, but research shows it’s probably best to follow the current recommendation of consuming between 10 and 35 percent of your daily calories from protein.

An analysis of 32 studies related to protein consumption found there is no benefit to consuming more protein than recommended. Too much could be useless at worst and detrimental at best for healthy individuals-in no small part because eating that much protein often comes at the expense of fiber, carbohydrates or other necessary nutrients. Eating too much protein for a prolonged period of time can cause a metabolic burden on your kidneys, liver and bones, as well as potentially increase your risk for heart disease and cancer.

Here are a few major warning signs to tell if you might be packing too much protein into your day.

How Much Potassium Is Safe

Its recommended that healthy men and women over the age of 19 consume at least 3,400 mg and 2,600 mg of potassium per day, respectively.

However, people with kidney disease who are on potassium-restricted diets usually need to keep their potassium intake below 2,000 mg per day.

If you have kidney disease, you should have your potassium checked by your doctor. Theyll do this with a simple blood test. The blood test will determine your monthly level of potassium millimoles per liter of blood .

The three levels are:

  • Safe zone: 3.5 to 5.0 mmol/L
  • Caution zone: 5.1 to 6.0 mmol/L
  • Danger zone: 6.0 mmol/L or higher

Your doctor can work with you to determine how much potassium you should ingest daily, while also maintaining the highest level of nutrition possible. Theyll also monitor your levels to ensure that youre staying within a safe range.

People with high potassium levels do not always have symptoms, so being monitored is important. If you do have symptoms, they may include:

  • fatigue

The Importance Of Protein

Is protein bad for my kidneys?

Proteins are the building blocks of life and every living cell uses them for both structural and functional purposes.

They are long chains of amino acids linked together like beads on a string, then folded into complex shapes.

There are 9 essential amino acids that you must get through your diet, and 12 that are non-essential, which your body can produce from other organic molecules.

The quality of a protein source depends on its amino acid profile. The best dietary sources of protein contain all essential amino acids in ratios appropriate for humans.

In this regard, animal proteins are better than plant proteins. Given that the muscle tissues of animals are very similar to those of humans, this makes perfect sense.

The basic recommendations for protein intake are 0.36 grams of protein per pound of body weight daily. This translates to 56 grams of protein for a 154-pound individual .

This meager intake may be enough to prevent downright protein deficiency. Yet, many scientists believe its not sufficient to optimize health and body composition.

People who are physically active or lift weights need a lot more than that. Evidence also shows that older individuals may benefit from a higher protein intake (

For detailed information on how much protein you should get per day, check out this article.

Processed Foods Are A Hidden Source Of K+

The transition from raw to processed foods began approximately 10,000 years ago with the onset of agriculture. Processing foods has increased the amount of Na+ and, in some cases, has reduced the amount of K+ intake. As previously discussed, inadequate consumption of K+ combined with excessive intake of Na+ is thought to contribute to the pathophysiology of a variety of chronic diseases such as obesity, hypertension, diabetes, kidney stones, and bone disease. As consumers and health agencies have pushed to reduce the amount of Na+ in processed foods, the food industry has begun to use food additives and preservatives, which are hidden sources of K+. These additives can significantly contribute to the total daily K+ content of foods because some preservatives in meat may add 300575 mg of K+ per 100 g of intake . Additionally, there are products used to enhance flavor which are KCl based and include salt substitutes where 20% of salt is replaced by KCl, which adds approximately 12 mmol/d to the usual K+ intake . In many cases, low K+ products may be high in Na+, making it difficult for patients with CKD to simultaneously adhere to low K+ and low Na+ food selections on a chronic basis .

Why Might I Need To Control Protein Sodium Phosphorus Calcium Or Potassium

Eating the right amount of protein, sodium, potassium or phosphorus may help control the buildup of waste and fluid in your blood. This means your kidneys do not have to work as hard to remove the extra waste and fluid.


Your body needs protein to help build muscle, repair tissue, and fight infection. If you have kidney disease, you may need to watch how much protein you eat. Having too much protein can cause waste to build up in your blood. Your kidneys may not be able to remove all the extra waste. It is important to eat the right amount of protein each day. The amount of protein you need is based on your body size, your kidney problem, and the amount of protein that may be in your urine. Protein intake should not be too low, or it may cause other problems. Your dietitian or healthcare provider can tell you how much protein you should eat.


Healthy kidneys control how much sodium is in your body. If your kidneys do not work well, too much sodium can cause fluid buildup, swelling, higher blood pressure, and strain on your heart. Your dietitian or healthcare provider can tell you the right amount of sodium you should have each day.



As kidney function gets lower, extra phosphorus can start building up in the blood. High phosphorus levels can cause bones to get weaker. Your dietitian or healthcare provider can tell you if you need to limit goods that are high in phosphorus.

The Real Cause Of Kidney Damage

The truth is that a much bigger cause of kidney damage is NOT protein, but high blood pressure.

Which, unfortunately, many people have and they dont even know it.

And the older you are, the higher your blood pressure is due to the negative changes in your hormones because of aging.

Also, anyone who doesnt sleep well, and is under daily stress, and also takes stimulants -including caffeine typically has high blood pressure through various parts of the day.

Heck, even Ive had mild hypertension in the past 3-4 years and thats why Ive been taking Blood Pressure Optimizer for a few years to keep my blood pressure in the low to a normal, healthy range.

Within a month, my energy levels improved, as did my sleep and of course, my blood pressure and also kidney function, when Ive done a blood test.

So, if you have high blood pressure or are concerned about kidney function, monitor your blood pressure daily and use a natural blood pressure-lowering solution like Blood Pressure Optimizer.

How Much Protein Is Too Much

Is Dietary Protein Intake Bad For Your Kidney

The body is in a constant state of flux, constantly breaking down and rebuilding its own tissues.

Under certain circumstances, our need for protein can increase. This includes periods of sickness or increased physical activity.

We need to consume enough protein for these processes to occur.

However, if we eat more than we need, the excess protein will be broken down and used for energy.

Even though a relatively high protein intake is healthy and safe, eating massive amounts of protein is unnatural and may cause harm. Traditional populations got most of their calories from fat or carbs, not protein.

Exactly how much protein is harmful is unclear and likely varies between people.

One study in healthy, strength-training men showed that eating around 1.4 grams per pound of body weight every day for a year didnt have any adverse health effects .

Even eating 2 grams of protein per pound of body weight for 2 months did not appear to cause any side effects (

My Partner Died Of Kidney Failure

Around 2003, I had a very successful nutritional supplement business specific for athletes and bodybuilders. I had a business partner who was much older than me and at the time, someone I *thought* was also wiser and more knowledgeable.

I really looked up to him at the beginning of our partnership and friendship.

Unfortunately, over time, the longer I got to know him, the less I respected his decisions and views on health, fitness, and longevity.

One of them was the use of high-protein diets.

I remember him telling me that in order to really increase my muscle mass, while minimizing fat gain, I need to eat a lot more protein. He suggested a minimum of at least 2 grams per pound of body weight and it would be much better if I had 3 grams.

At that time, I was eating 1 gram per pound. Thus, I weighed about 200 lbs and ate 200 grams of protein.

But he suggested I increase it to 400 grams and preferably 600 grams, daily to start seeing the real muscle-building benefits.

He himself, being very muscular and lean at 250 lbs, was eating almost 1000 grams of protein daily and said that was ONE of his secrets. Most of the protein is from fast-digesting Whey protein.

And so, I decided to give it a try because I trusted him.

After all, he was 7 inches shorter than me and yet, he had an extra 50+ lbs of muscle.

Over the next 3 months, I slowly increased my protein to eventually eating 600 grams daily. It was about 100 grams, 6x daily.

Was this all because of the high protein diet?

How Many Grams Of Protein A Day Is Too Much

If there is a level of protein intake that is excessive and damaging to kidney health, we dont currently have evidence to show what this may be.

In other words, there is currently no such thing as too much protein regarding negatively impacting renal function.

Studies show that protein intake at up to 35% of total energy intake has no adverse effect on people with healthy kidneys.

The four studies mentioned in this article also consider all different people.

From resistance-trained individuals to pre-diabetics, people with abdominal obesity, and average healthy adults, no harm was found from increasing protein intake.

Of course, we should still be sensible, and we shouldnt overeat protein just for the sake of it. But overall, the data suggest that there would be no harm from consuming around 1 gram protein per pound of body weight.

Consuming more protein than this would likely be unnecessary for the majority of people.

Protein And Kidney Disease

If you have chronic kidney disease, kidney function is already decreased. Because of this, you have to be extra careful with how much work you make your kidneys do. Healthy kidneys can handle the extra load of excess protein, but damaged kidneys can’t. According to the National Institute of Diabetes and Digestive and Kidney Diseases, eating more protein than you need makes your kidneys work harder, and this can speed up the progression of kidney disease.

On the other hand, a March 2018 report in Chronic Diseases and Translational Medicine notes that a low-protein diet may slow the progression of kidney damage in those with moderate to advanced kidney disease or failure. Another report published in PLOS One in November 2018 had the same findings. Researchers also concluded that eating less protein can help improve heart health in those with chronic kidney disease.

Why Is An Eating Plan Important

Is Whey Protein Damaging For Your Kidneys?

What you eat and drink affects your health. Staying at a healthy weight and eating a balanced diet that is low in salt and fat can help you control your blood pressure. If you have diabetes, you can help control your blood sugar by carefully choosing what you eat and drink. Controlling high blood pressure and diabetes may help prevent kidney disease from getting worse.

A kidney-friendly diet may also help protect your kidneys from further damage. A kidney-friendly diet limits certain foods to prevent the minerals in those foods from building up in your body.
