Can Pea Protein Cause Constipation

Which protein powders are safe for kidney stone formers? / Kidney Stone Diet with Jill Harris

Its no secret that a high protein, low carb diet is popular these days. After all, protein leaves you feeling fuller, longer. But for some who up their protein intake, this lifestyle change results in less, ahem, movement. So does pea protein normally cause constipation? No, this is another one of the myths about pea protein.

Many forms of traditional medicine, such as Ayurvedic and Chinese, utilize peas specifically to promote digestive health. Not only are they easy to digest, peas fiber content helps keep you feeling full, cutting down on unhealthy eating. This strengthens the digestive tract and promotes regularity.

The Harmful Side Effects Of Whey Protein

True athleticism isnt about being stronger or fasterits about longevity. Some shine bright and fizzle out quickly, while others can keep going for years. Its not about how good you are in your prime, its about how long you can stay in your prime. Many professional athletes have discovered that a dairy-free diet is key to enhancing their performance and maintaining their peak for years past their expected retirement age. These leaders are moving the needle toward plant-based fuel in sport, but the misconception surrounding dairy and performance nutrition still lingers. Whey is still the most commonly used protein supplement by athletes and trainers according to a just-released paper, Whey protein supplementation and its potentially adverse effects on health: a systematic review. Per the reviews title, whey protein is not the healthy muscle-maker that marketing makes it out to be.

Sodium Intake Affects Urine Calcium Response To Acid

In a prior article I showed the urine calcium lowering effects of potassium citrate were independent of the effects of diet sodium. But those data, and trial data like it are observations. Suppose you give people an acid load so their urine calcium goes up as a result of what you did and also varied sodium intake a direct experiment, not observations.

I did that, and although others also may have done the same, my experiment was a good one and I like it.

Four people were studied during three control days points to the left on the graph. They had normal urine calcium excretions , normal serum PTH levels and normal serum total calcium and ionized calcium . That is what one expects from normal people.

I gave them ammonium chloride which is an acid load, and as you might expect by now their urine calcium should go up. But, I also lowered their sodium intake to 40 80 mEq daily and take a look urine calcium did not change.

Their blood became distinctly acidic you will have to look at the paper. The calcium ion rose and the total calcium fell because the acidity tends to liberate calcium ion from binding to blood proteins and from phosphate complexes.

I then raised the diet sodium to about 200 mEq and there was the urine calcium increase. Serum PTH went up, too, perhaps because the kidneys were losing calcium.

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.

Kidney Stones : The 4 Main Types

Can Whey Protein Cause Kidney Stones?

A kidney stone is a solid mass that can be excreted from the kidney thats not supposed to happen. It typically means that theres insufficient liquid, or that your body isnt using the solids as its supposed to .

But the stone itself can be made of a variety of material, and in different combinations.

In general, there are 4 main types of kidney stones:

  • Calcium stones This is the most common form by far. They are usually comprised of calcium and oxalate .
  • Struvite stones These grow fast and large, and are created as a result of an infection.
  • Uric acid stones Usually formed as a result of the purines in a high protein diet, or dehydration. Can also be affected by genetic factors.
  • Cystine stones Caused by genetic disorders, but not very common.
  • When it comes to vegan protein powder and kidney stones, we care most about calcium stones , and uric acid stones.

    Can Pea Protein Cause Upset Stomach

    Another one of the top myths about pea protein is that it can cause an upset stomach, or be hard to digest. Fortunately, pea protein is highly digestible, ranking at an impressive 98 percent on the digestibility rating scale. This means that, for most people, pea protein should not cause an upset stomach or make you feel sick. Because pea protein lacks common food allergens, such as dairy, wheat, and nuts, its a better choice for those with food sensitivities or allergies.

    For the many people that experience dairy intolerance, ingesting milk-based products leads to upset stomach, pain and even diarrhea, as their bodies cannot easily digest dairy. Pea protein offers an alternative. Free from dairy and other common irritants, Nuzest’s pea protein offers a clean choice for those with food allergies, vegans and vegetarians alike.

    What Is Whey Protein

    First you should know what whey protein actually is and what it is supposed to be used for. Whey protein is normally found in a powder form and is used as a daily protein supplement. That is not all that it can be used for though.

    It is also used sometimes to improve athletic performance, to supplement milk-based infant formulas, and also for replacing glutathione in HIV patients. Whey protein is a mixture of beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin, and immunoglobins.

    There seems to be many benefits to consuming whey protein including: losing weight, anti-cancer properties, lower cholesterol, asthma, and lowering blood pressure which reduces the risk of cardiovascular disease.

    Whey protein is loved by many, and with all of those amazing benefits it can offer it really doesnt seem so bad.

    Make a root beer float with extra whey protein powder and six ounces of cool root beer for a delightful evening treat. Finish the scoop of whey protein powder by combining it with a half cup of applesauce later in the evening. For a refreshing, delicious, and high-protein evening snack, place the applesauce in the freezer for a few minutes.

    Should Everyone Avoid A High

    Does A High Protein Diet Cause Kidney Damage or Stones (Clinical Evidence Included)

    Dr.Calle advises patients with chronic kidney disease to take the better safethan sorry route. They probably should limit protein, he says.

    His advice also applies to people who have a history of kidney stones or certain rare genetic conditions like phenylketonuria . That can put them at higher risk of forming kidney stones, which may potentially affect their kidney function, too.

    But even if your kidneys seem to be firing on all cylinders, its still a good idea to check with a doctor before making any drastic changes to what you eat. Diets arent one-size-fits-all. A doctor can help you find an eating plan thats appropriate for your health goals.

    Kidney And Liver Function

    Even during short-term use, whey protein consumption was found to negatively affect kidney function. In a 2011 study, those who consumed whey-based protein during the experiment experienced increased plasma urea, urinary volume, and urinary calcium excretion while the pH of urinary citrate decreased. Essentially, this indicates an increased taxing of the kidneys, which marks the first step in kidney disease.

    In regards to liver function, those who live generally sedentary lives are most affected. Researchers found that when not exercising, the proteins from the whey supplement ended up going to the liver for processinginstead of being used for muscle synthesis. Over time, sedentary participants showed signs of early liver injury. While whey protein is heavily used by athletes, many non-athletes consume it as well. Whey protein can be found in meal replacement shakes and other diet-related food products that promise weight loss or increased muscle mass through food alone. This becomes an issue because consumers are led to believe that whey is akin to a superfood, when in reality it could damage their liver over time.

    Picking The Right Meal Replacement Shakes

    While we have established that meal replacement shakes are not as harmful to the kidney as you may have led to believe, there are still concerns regarding the right kind and right amount of these things.

    As we have discussed multiple times above, the main culprit in meal replacement shakes is the excessive protein. With solid sources of protein like milk, cheese, meat, etc., the body takes its time to digest the protein. However, this is not the case with meal replacement shakes. The protein in these powders is absorbed much faster by the body.

    For this reason, you should always be mindful of the amount of protein youre putting in your body while replacing your regular solid meal for a meal replacement shake.

    You will have to track the amount of your daily protein intake and make sure it is within a healthy range. The recommended amount depends on how much physical activity you partake in.

    • If youre an athlete or someone who does strength training regularly, you will need 0.7 to 0.8 grams of protein for every half a kilo of your body weight.
    • If you are someone who engages in a minimal amount of physical activity, your recommended daily dosage is 0.3 grams per half a kilo of your body weight.

    Measuring the amount of protein is pretty straight forward. Check the labels of your meal replacement powder for the amount of protein per given weight.

    Now depending on how many times per day you plan on drinking these replacement shakes, divide the amount accordingly.

    Can Pea Protein Cause Acne

    Can Whey Protein Cause Kidney Stones?

    When youre working hard to get lean and healthy, the last thing you want to deal with is acne. Unfortunately, acne breakouts and protein seem to go hand in hand especially if that protein comes from whey.¹

    Why? Because whey protein powders have been linked to an uptick in acne. When extracted from cows milk, whey may affect several hormonal growth factors, which studies suggest may exacerbate breakouts.²

    You might ask, can pea protein cause acne? This is one of the myths about pea protein that are circulating the Internet. Fortunately, pea protein comes from plants and does not contain acne-triggering hormones. Instead, this clean source of protein offers the complete range of amino acids necessary for muscle health and energy, without the disruptive hormones. In short, pea protein can help keep your skin clear and healthy.

    Over the years there have been many different products that are believed to be healthy or safe, for a while at least.

    From diet pills to certain forms of sugar, the truth is that you never really know the risks of something you are putting into your body sometimes until it is too late.

    There have been studies done to prove or disprove the idea of whey protein being able to cause kidney stones, so whats the truth?

    How Much Protein Do We Need

    A subsequent WHO meta analysis of mostly the same underlying data supplemented by more recent studies comes to much the same conclusions, but in perhaps a more nuanced manner. A more recent analytical critique of the whole matter is not remarkably far off in estimates for adults, though pregnancy and childhood seem controversial.

    This summary graph from the critique gives a sense of how the protein requirements are set. The median requirement is where about half of all studied subjects were in neutral nitrogen balance their body protein mass would be stable, a very important matter. The safe population intake is set higher. The safe individual value is high enough enough that 97.5% of the individuals in a population would be in balance: almost all people would not lose protein mass consuming this amount of protein for example muscle. The Safe population intake is set higher. Although the safe individual intake is correct, within a population individual requirements vary, so the recommended level needs to be increased so that 97.5% of the individuals in a population offered that recommendation will be in balance.

    That number from the WHO meta-analysis, the safe population intake, is about 1.05 gm/kg body weight/day.

    Consuming too much of the bad stuff such as meat, salt and soft drinks can increase your risk.

    But certain fruits and vegetables, too? So, which is the more likely cause of kidney stones?

    The most common causes of kidney stones in Singapore are related to insufficient fluid intake, too much salt in the diet and too much protein, said Dr Tan.

    Still, it is interesting to note that too much of a good thing can be bad for you.

    Here are some examples of healthy habits or intentions that may increase your risk of or exacerbate your kidney stones:


    Too much Vitamin C can be an issue as it combines with calcium to form calcium oxalate a precursor to certain kinds of kidney stones.

    Vitamin C in high doses is a problem, said Dr Tan.

    And by that, he means doses of more than 500mg per day. In fact, I would rather my patients keep to a maximum of 200mg per day, he said.


    Calcium supplementation in large quantities, and when taken separately from meals, may set you up for kidney stones, according to a study published in the Translational Andrology And Urology journal.

    But calcium is necessary for strong bones, and it is lacking in Singaporeans’ diets, said Dr Tan.

    Furthermore, although it sounds paradoxical, calcium can also prevent kidney stones.

    But if boosting your calcium intake doesnt lower your urine oxalate level, the same programme suggested watching your oxalate intake.

    Chronic Kidney Disease And Diet

    Tention Free

    From 1990 to 2010, the incidence of Chronic Kidney Disease has doubled. In a review of the standard American diet and its effects on the kidney, the diet appears to have negative effects on human renal function. A decline in renal function was observed in those who consumed an animal protein-rich diet, as compared to those consuming a plant protein-rich diet. Consumption of excessive animal proteins leads to a marked acid load to the kidney, and has been associated with the development of kidney stones. Higher meat consumption leads to increased renal acid excretion and the production of ammonia, which can cause metabolic acidosis and a higher risk for tubulointerstitial injury. In addition to eliminating meat, it is beneficial to add dietary fiber. In a meta-analysis of 14 trials involving 143 participants, the additional dietary fiber significantly reduced serum urea and creatinine levels.

    Consumption of animal products impairs renal vascular function, leading to increased inflammation and subsequent microalbuminuria. Studies show that meat ingestion impacts factors such as GFR, glucagon, prostaglandins, and increased albuminuric response. Glomerular hyperfiltration is thought to be due to an inflammatory response via vasodilatory prostaglandins, as a result of animal protein consumption. This is supported by studies showing that the level of hyperfiltration decreases when indomethacin is administered.
