Recommended Diet for a Dialysis Patient

While you’re on dialysis, it’s important to be cognizant of what you’re eating. While on dialysis, it’s important to monitor your intake of sodium, potassium, protein, phosphorus, and the amount of fluids in the foods you consume. The best option would be to meet with a kidney dietician, however here’s a helpful guide to get you started today.

Low-Sodium
While on dialysis, keep your sodium intake to less than 2,000 mm per day. Many of the foods we eat today have sodium added as a preservative. Be sure to read labels and avoid canned foods that are high in sodium. Shop for snacks that are low-sodium or don’t have salt added. It’s good to keep in mind that if food has the label “low-sodium,” it could mean a lot of potassium has been added to substitute the salt.

Low-Potassium
Whole grain foods, bananas, tomatoes, potatoes, orange juice, and cereals can all contain high amounts of potassium. Good substitutions for these foods are choosing white bread instead of whole grain, rice over pasta, and fruits and vegetables such as broccoli, cucumbers, carrots, and applesauce.

Lean-Protein
Sources of protein, such as meat, is a key ingredient in your dialysis diet. Choose lean meats that don’t have a high content of salt or any added gravies. These meats can be beef, fish, chicken, and pork. You can also achieve your protein goals by eating foods like black beans, kidney beans, nut butter, and limited amounts of cheese.

Low-Phosphorus
Foods that are high in phosphorus are dairy products, meats, and whole grains. As mentioned above, meats can be an excellent source of protein for patients on dialysis, so be sure to eat whole grains and dairy products in moderation.

Plenty of Fluids
The amount of fluids you should drink will depend on the amount of urine your kidneys produce, so pay close attention to your doctor’s recommendation. Juices that are good for kidney dialysis patients are apple, grape, and cranberry juice. You can also drink tea, water, and clear sodas to keep yourself hydrated.

Mediterranean Food and the Heart

Jamie Stanos - Mediterranean Food and The Heart 1Whether it’s a hearty tomato sauce or some light cured meat, Mediterranean food is delicious.  That’s not news to anybody.  But in a recent study published in the American Heart Association’s journal Circulation, researchers reported their findings that Mediterranean food, particularly enriched with virgin olive oil, could boost the cardioprotective effects of good cholesterol.  

There are two types of molecules called “lipoproteins” that carry cholesterol in the blood: low-density lipoprotein (LDL) and high-density lipoprotein (HDL).  Since high levels of LDL can bring about plaque buildup in arteries, it’s considered “bad” cholesterol.  HDL, on the other hand, is considered “good” cholesterol, since it absorbs cholesterol and carries it to the liver to flush it from the body.  There’s been growing evidence that a Mediterranean diet protects against the development of heart disease, and studies have shown that it improves the lipid profile of HDLs.  Yet there’s evidence that HDL doesn’t work as well in people at high risk for various cardiovascular diseases, and its functional ability matters just as much as quantity.  Yet small-scale trials have also shown that antioxidant-rich foods like virgin olive oil, tomatoes and berries all improved HDL function in humans.  Therefore, the researchers aimed to determine whether eating a Mediterranean diet enriched with virgin olive oil or nuts would improve the benefits of HDL in humans.  

The researchers randomly selected 296 individuals with a high risk of heart disease, with an average age of 66, and were assigned to one of three diets for a year.  The first was a “traditional” Mediterranean diet enriched with around 4 tablespoons of virgin olive oil per day.  The second was the same, although it was supplied with nuts instead of olive oil.  The third was a healthy “control” diet that contained reduced amounts of red meat, high-fat dairy products, processed foods and sweets.  Both Mediterranean diets included fruit, vegetables, legumes and moderate amounts of fish and chicken.  At the start and end of the study, blood tests were conducted to measure LDL and HDL levels.  

The researchers discovered that total and LDL cholesterol levels were only reduced in the healthful control diet.  Although none of the three diets significantly increased HDL levels, both of the Mediterranean diets improved HDL function, which was more pronounced in the group enriched with virgin olive oil.  HDL functions such as reversing cholesterol transport, providing antioxidant protection and enabling vasodilation were all improved.  Although the control diet was rich in fruits and vegetables like the Mediterranean diets, it had an adverse impact on HDL’s anti-inflammatory properties, an impact not observed in the Mediterranean diets.  Yet the researchers only found slight differences in results between diets, as expected, since the variation between the two Mediterranean diets was modest and the control diet was still healthy.  Nonetheless, this research could pave the way for new ways to fight heart disease.

Cheese For the Heart

Cheese for the heart by jamie stanosOver the years, I’ve heard a whole lot of different proposed diets: Atkins, South Beach, Jenny Craig, Weight Watchers, all-carb, no-carb, you name it.  These mostly promise the same result: improved health and spectacular weight loss.  But all of them offer wildly varying, often contradicting, means to that end.  Yet a quiet revolution in mainstream scientific thinking has begun to take hold, one that views full-fat dairy products differently.

Cheese has almost always been viewed as a fattening food that’s dangerous to our heart health.  Yet directly in contrast to veganism and pretty much everybody’s preconceived notion, Dr. Arne Astrup, professor and head of the department of nutrition, exercise and sports at the University of Copenhagen, cheese is actually beneficial to cardiovascular health.  At the American Heart Association scientific sessions, Astrup declared that a diet of cheese plays a large part in managing type 2 diabetes and cardiovascular disease.  He doesn’t think that there’s any harmful effect from eating cheese, but is rather beneficial.  

In a recent comprehensive meta-analysis of 31 prospective cohort studies, a high dairy intake was associated with a 9% reduction in the risk of stroke, an 18% lower risk of coronary heart disease and a 13% reduction in risk of stroke.  Investigators in the Netherlands (a country known for their love of cheese) made a meta-analysis of 18 prospective cohort studies found that risk of stroke fell 7% for each 200 ml of dairy consumed every day, while consumption of 25 gm a day or more of cheese was associated with a 13% reduction in stroke risk and 8% lower risk of CHD.  A joint Chinese/Dutch meta-analysis found a 14% relative risk reduction for CHD and a 10% lower risk of stroke with high versus low cheese intake.  

This “classic lipid” hypothesis tied with cardiovascular disease says that dietary saturated fat raises blood cholesterol, which in turn accelerates atherosclerosis and CHD.  Yet recent studies indicate that not all saturated fats are equally harmful, and have vastly different biological effects.  For example, the saturated fatty acids and trans fats in red meat are damaging, yet those in dairy products are actually cardioprotective.  According to Dr. Astrup, fermented dairy products contain a long list of potentially beneficial nutrients in addition to saturated fats.  Strong evidence suggests that a diet high in dairy products reduces the risk of childhood obesity and enhances body consumption in adults.  Even the World Cancer Research Fund has weighed in, concluding that dairy products probably protect against colorectal, breast, gastric and bladder cancer.

What People on Dialysis Want You to Know

What people on dialysis want you to know by Jamie StanosBeing on dialysis is a tough experience.  If somebody you know and care about is on dialysis, here are some things they want you to know, based off a blog post I recently read:

You don’t understand what it’s like: You’ll never understand what it’s like to be on dialysis, but that’s okay.  Somebody on dialysis will always appreciate the effort you make to understand their situation and cater to their needs.

They’ll be upset sometimes, but it isn’t about you: Even if somebody on dialysis is upset when you visit them, that doesn’t mean they want you to stop visiting them altogether.  If they’re upset, it might have to do with any of the things that could make dialysis an unpleasant experience.  Don’t take it personally, it has nothing to do with you, and it doesn’t mean you should stop visiting.

They’ll have to cancel plans a lot: Sometimes somebody on dialysis doesn’t feel like getting together because they’re sick or tired, it has nothing to do with you.  Dialysis patients crave social interaction just as much as everybody else, and still want to do the same fun stuff they used to enjoy, but it might not always be possible.  Related to the previous point, just because somebody on dialysis keeps canceling plans, it doesn’t mean that they don’t want to see you.

There’s no cure, just treatment: This is a hard thing for anybody to wrap their head around: there’s no cure for ESRD, simply treatment.  If they stop getting treatment, they’ll die.  This is a scary thing for somebody on dialysis to live with: every day they need to make the conscious decision to live.

They’re probably bitter: Kidney failure isn’t fun.  Interminable hours spent on dialysis, keeping track of everything you eat and drink, massive needles and constant doctors appointments take their toll.  It can be hard to handle.

They’ll pretend things are better than they actually are: When somebody on dialysis says they’re “okay”, there’s a chance they are some things they’d rather not discuss.  There’s always something going on with a dialysis patient, though they might not think you need to worry about everything.

What is Hemodialysis?

Dialysis is a medical procedure in which excess water and waste matter are removed from a patient’s blood. This practice is most commonly used for individuals who have experienced loss of kidney function and/or kidney failure, and for patients with end-stage renal disease. To put it simply, dialysis is artificial kidney function. There a few different types of dialysis methods; one of the  major primary methods is Hemodialysis which is  used “when preemptive kidney transplantation is not possible”. (source).

Hemodialysis

This dialysis process acts as the kidneys to remove waste and extra salt and fluid from the blood. Hemodialysis involves the removal of the blood from the body, so that it can be run through a dialyzer, which filters the blood.
The blood is both removed from and returned to the patient’s body through an access, which will either be a vascular access like an AV graft or AV fistula, or through a catheter. Only a small amount of blood is removed from the body at once, and the blood is moved through a series of tubes to the dialyzer.

Traditional hemodialysis is a very regimented treatment. Typically hemodialysis is performed in a dialysis center, and patients receive the treatment three times a week for four hour sessions. Patients will either be placed on a Monday/Wednesday/Friday schedule or a Tuesday/Thursday/Saturday schedule, and then scheduled a time of day to receive treatment as well. Due to the fact that the treatment is complex, there is little room for flexibility in terms of schedule. (source)

Home Hemodialysis

However, recent technology advancements have made it possible for some dialysis patients to treat themselves at home with HHD (Home HemoDialysis). This process is absolutely not for everyone, as it involved the learning and comprehension of a great deal of information. The success of home hemodialysis is dependant on the patient (or caregiver’s) knowledge of the treatment.

If home hemodialysis is a safe treatment option for the patient, it allows for more much more flexibility. There are three subtypes of home hemodialysis: Conventional, Short Daily, and Nocturnal.

Conventional home hemodialysis is performed exactly as it would be in a dialysis center. The treatments still take place three times a day, for four hours a day on the alternating day schedule. Training for the conventional practice can be short as several weeks to as long as several months depending on the patient’s specific case.

Short Daily home dialysis is performed more frequently throughout the week, for shorter amounts of time than traditional dialysis sessions. These sessions will last around 2 hours, and take place over as few as 5 days and as long as the full 7 days of the week.

There are a few inherent benefits of this type of treatment. For one, the training time is a few weeks vs a few weeks to months. The frequency of the treatments means less blood is being removed during each session. This means the side effects and symptoms of treatment are lessened.

Nocturnal home dialysis is a much slower process, which takes place over the length of your sleep (6-8 hours). Depending on what the physician recommend, the treatment can be delivered every other night or 6 days a week.

The benefit of the nocturnal treatment is that the longer process allows for more waste to be removed from the blood on a weekly basis.

Former President of ACC Recommends Veganism

jamies stanos heart

In 2014, the (then) president elect for the American College of Cardiology, Dr. Kim A. Williams,  published an article on MedPage Today that both explained his experience with veganism, and why he recommended the diet his patients suffering from hypertension and Type 2 diabetes (among other medical afflictions). The article brought on a great deal of backlash from the Cardiology community, as many medical professionals felt he was pushing a “radical” diet on everyone based on just his individual experience. Dr. Williams dismissed these claims as not being true.

Controversy aside, Dr. Williams’s article and experiences with veganism offer some interesting insight into (his experience) benefits of veganism.


Dr. Williams noted in his article that he became interested in the vegan diet after he learned that his LDL cholesterol numbers had increased by 60 points in just a few years. Dr. Williams noted that his exercise habits had faltered over those years, but he also had suspicions that his diet was also playing an active part in his cholesterol levels. The cholesterol levels found in food often has a negligible effect on blood cholesterol levels, but do have major effects on certain people, and Dr. Williams believed he was one of them.

Dr. Williams’s diet of no red meat, fried foods, and minimal dairy was clearly not doing the job at maintaining his health as he thought, so he switched to a “cholesterol free” diet, which was for all intents and purposes a vegan (plant based) diet. He found that in six weeks, his LDL cholesterol levels were significantly reduced and were a 90 at his next blood test.

Dr. Williams’s experience (and the results he saw) with his switch to a vegan diet were extraordinary, and definitely offered a glimpse of what veganism was capable of…for certain bodies. Even Dr. Williams acknowledges that the results from such a dietary switch can be variable.

In Dr. Williams’s article on MedPage Today, he also noted that the studies suggesting a connection between plant based diets and reduced heart disease are either “very large and observational or small and randomized” and “ larger randomized trials are needed. ”


Veganism continues to be a controversial topic, and research continues to look for solid links between plant based diets and overall health. While I always encourage a “healthy” diet, I continue to be interested in exactly what is truly considered “healthy”.

Is it a fully plant-based diet? Is it vegetarianism? 

As this article published by Harvard Health Publications stated,

there still aren’t enough data to say exactly how a vegetarian [or vegan] diet influences long-term health.”

It will be interesting to see what conclusions the medical field will be able to draw with continued research.

Post-Op Atrial Fibrillation Treatment Methods Deemed Equally Efficient

jamie stanos cardiac surgery

One of the most common complications that patients endure after undergoing cardiac surgery is postoperative atrial fibrillation. The unfortunate reality is that the condition can occur in up to 50% of post-op patients, and it can lead to everything from multiple hospitalizations to long-term mortality. There are currently two different approaches that cardiologist can take when addressing postoperative atrial fibrillation.

The two methods are rate control and  rhythm control, and researchers at the Cleveland Clinic recently carried out a large-scale randomized control clinical trial to determine which of the two methods was more effective.

Postoperative atrial fibrillation is a common complication of cardiac surgery and adversely affects patient recovery. In patients with postoperative atrial fibrillation, one strategy does not appear to have a net clinical advantage over the other, but there are clinical differences between these strategies. The results of this trial fill an important knowledge gap and should better inform therapeutic decisions for this common complication,”  – Annetine C. Gelijns, Ph.D.

When the rate control method is implemented, the heart rate is slowed down via medication.

When the rhythm control method is being used, the heart’s normal rhythm is restored through electrical shock.

Through their research, they determined that neither was better; the rate control and rhythm control methods are equally effective. Marc Gillinov, MD of the Sydell and Arnold Miller Family Heart & Vascular Institute noted that these results create a case for creating a standardized strategy of starting with rate control first, to avoid the toxicity risk related to the rhythm control agents.

Dr. Gillinov and his team studied 2,109 patients that elected to have cardiac surgery. 40% of the patients had coronary artery disease, 40% had heart valve disease, and the remaining 20% had a combination of the two conditions.  696 of the patients developed post-op atrial fibrillation, and 75% of those patients received randomized treatment (rhythm or rate control).

The results for both treatments were interesting:

  • The number of dates that all of the patients stayed in the hospital after receiving the treatment was equivalent
  • If the patients experienced serious adverse effects, they were similar between the two methods.
  • The differences that did occur between the two treatments ended up cancelling eachother out:
    • The rhythm control medication worked more quickly, but the side effects were so harsh that patients needed to switch treatments
    • Rate control treatment had a higher re-occurance rate

But, neither could be deemed more effective than the other.

New Sequencing Panel Allows For Detection of 174 Genes Related to Heart Disease

genetics

 

From a genetic standpoint, one of the most commonly inherited diseases is heart diseased. Nearly 1% of the population is affected by inherited heart disease, but up until now, the testing process for the inherited genes has been extraordinarily difficult.

A sequencing panel has been developed that has the potential to change the face of cardiology for the better. In the past, testing for genetic signals of heart disease was a costly and unwieldy process. When trying to determine whether or not a patient’s heart conditions were genetic (or to determine what the genetics were that caused an inherited condition), medical professionals were limited to very specific tests that only focused on singular genes. It was impossible to efficiently test, and if the specific tests were inconclusive, then researchers and doctors would be forced to “serial test”, with the hopes of stumbling upon a solution.

The company Illumina has eliminated some of that inherent struggle with their development of TruSight. TruSight is sequencing panel that focuses specifically on genes that are associated with heart conditions. Trusight Cardio has made 174 genes associated with cardiac conditions available to be tested for, and Illumina has worked to include casual variants of the genes as well. This means that both “core genes” and genes that were considered emerging genes were included in the panel.

The senior product manager for Illumina’s generic health business was quoted saying:

“Existing gene panels for profiling genes related to inherited cardiac conditions tend to be smaller in size, leading to revalidation of bespoke panels, or having to send out tests when a particular set of genes are not available”.

Ilumina’s goal was to create a more flexible space for cardiologists and researchers.  With their new sequencing panel, clinical researchers now have the ability to see as many genes as they felt were necessary for the research situation at hand. Not only was there an increase in the availability of genes, but Illumina in the year of development, they also successfully created TruSight to have a quick turnaround in labs, and a reasonably low price point.

TruSight will make for a much more effective diagnosis process, and will inevitably save a great deal of time, money, and lives in the long term.

Naturally Reenergize Your Body – Part 1

cycling

 

Our society is one that truly never sleeps.  In order to lead a successful life, our bodies wake up early, commute, work, communicate, and stay up late to tie any loose ends to our days. We are constantly on the go, and all of demand we put on our body through daily tasks and responsibilities takes a toll on our overall energy. There are a few different steps that one can do to replenish and then boost your body’s daily energy.

 

Eat Small, More Often

The “eat small meals, multiple times a day” schedule is famous because of the belief that it lead to weight loss. While that has not been proven, it has been proven that multiple small meals a day can have a direct correlation to increased energy levels. Our brains use glucose as food. Low levels and high levels of glucose effect the brain similarly; they lead to feelings of sluggishness and a lack of energy. Our current “normal” eating schedules make it impossible to not have unregulated levels of glucose in our bodies, which means we are creating periods of low energy. (We’re used to little or no breakfast and large lunches.)  The key is to start with a fully balanced breakfast, and then eat small, nutritious snacks and meals about every 3-4 hours.

 

 

Have A Regular Sleep Schedule

Before modern technology, our brains were trained to release neurotransmitters to the rest of the body that coincided with the sun rising and setting. Our brains and bodies were on a consistent, rhythmic schedule that would sleep when darkness set in and wake up when it was light out. These days, our natural rhythms are interrupted by alarms and routines that keep our sleep schedules erratic. It is up to us to re-regulate our bodies by getting up at the same time and going to sleep at the same time every day. That regularity allows our bodies to sleep more efficiently, which directly correlates to more the recuperation of energy.

Be sure to check back next month for more tips to naturally increase your energy.

A Beginner’s Guide to Running

runner

As we round the corner of the new year, the mental new year’s resolutions to form. Becoming a more healthy and fit version of one’s self is usually high on the resolution list, and many people turn to running.

Before you throw yourself into running, do a little prep work. These are some tips that you keep in mind to make sure that you’re not only running safely, but you’re getting the most out of your new running regimen.

 

Pick Out Your Running Shoe

This may not seem like an important step, but picking the correct shoe is key to maintaining long term physical health. You need to make sure that you choose a shoe that caters to both your body and your specific running needs. Keep the following things in mind when choosing your shoe:

 

  • Make sure you get your feet sized in the store. If your feet are distinctly different sizes, it may make sense to go to a specialty store to purchase differently sized shoes; you want them to fit perfectly.
  • Choose shoes that have a small heel-to-toe drop (the difference in thickness between the cushion in the front of the shoe and the heel of the shoe). Keeping the heel-to-top drop small ensures that your feet will properly support your weight with every step

 

Set Multiple, Realistic Goals

One of the biggest mistakes that people make when starting to run is allowing themselves to get discouraged too easily. If you have no history of running, it’s okay that you aren’t immediately able to run a 5K. Set your own pace, and make realistic goals for your body. A goal can simply be “I’m going to run for a solid 10 minutes”. When you have achieved one goal, set another. Ramp yourself up as you learn what your body can and cannot take. Don’t be ashamed of your pace.

Create A Schedule

If you have not run before, or are out of practice, don’t start out trying to run every day.  Your muscles need time to rest and repair in between your workout sessions. Since running is impact-heavy, you can start out by alternating between running one day and doing something low impact the next. On a week-to-week basis you can start to ramp up the amount of time/distance that you are running. Remember not to try to do too much all at once.
