What Happened to the Rice Diet?

What Happened to the Rice Diet?.jpeg

During his career at Duke, Dr. Walter Kempner treated more than 18,000 patients with his rice diet. The diet was originally designed as a treatment for kidney failure and out-of-control high blood pressure at a time when these diagnoses were essentially a death sentence. Patients who would have died in all other hospitals had a reasonable chance for survival if they came under Kempner's care.

The results were so dramatic that many experienced physicians suspected him of falsifying data, because he was essentially reversing terminal diseases with rice and fruit, diseases understood to be incurable by the best of modern medicine at the time. Intensive investigations into his clinic vindicated his work, however, which other researchers were then able to replicate and validate.

Kempner was criticized for his lack of controls, meaning that when patients came to him he didn't randomly allocate half to his rice treatment and put the other half on conventional therapy. Kempner argued that the patients each acted as their own controls. For example, one patient, after the medical profession threw everything they had at him, still had blood pressure as high as 220 over 160. A normal blood pressure is considered to be around 120 over 80--which is where Kempner's rice diet took him. Had the patient not been given the rice diet, his pressures might have been even lower, though: zero over zero, because he'd likely be dead. The "control group" in Kempner's day had a survival expectancy estimated at 6 months. To randomize patients to conventional care would be to randomize them to their deaths.

We can also compare those who stuck to the diet to those who didn't. In one study, of those who started the rice diet but then stopped it within a year, 80% died. For those who made it a year but then gave up the diet, instead of an 80% chance of dying, they had about a 50% chance, a flip of the coin. Of those that stuck with the program, 90% lived to tell the tale.

Beginning in the late 1950's, drugs became available that effectively reduced blood pressure and hypertension, leading to a decreased demand for the rice diet. What conclusions can we draw from this all-but-forgotten therapy for hypertension? Not only was it the first effective therapy for high blood pressure, it may be equal to or more effective than our current multi-drug treatments. See Drugs & the Demise of the Rice Diet.

This causes one to speculate on the current practice of placing patients on one drug, then another, and perhaps a third until the blood pressure is controlled, with lip-service advocacy of a moderate reduction in dietary sodium, fat, and protein intake. At the same time, the impressive effectiveness of the rice-fruit diet, which is able to quickly stop the leakage from our arteries, lower increased intracranial pressure, reduce heart size, reverse the ECG changes, reverse heart failure, reduce weight, and markedly improve diabetes, is ignored.

Should we return to the Kempner protocol of starting with the most effective therapy, saving drugs for patients who fail to respond or who are unable or unwilling to restrict their diet? Today many people follow a plant-based diet as a choice, which is similar to what Kempner was often able to transition people to. After their high blood pressure was cured by the rice diet, patients were often able to gradually transition to a less strenuous dietary regime without adding medications and with no return of the elevated blood pressure.

If the Kempner sequence of a strictest of strict plant-based diets to a saner plant-based type diet offers the quickest and best approach to effective therapy, why isn't it still in greater use? The powerful role of the pharmaceutical industry in steering medical care away from dietary treatment to medications should be noted. Who profits from dietary treatment? Who provides the support for investigation and the funds for clinical trials? There is more to overcome than just the patient's reluctance to change their diet.

What Kempner wrote to a patient in 1954 is as true now as it was 60 years ago:

"[D]rugs can be very useful if properly employed and used in conjunction with intensive dietary treatment. However, the real difficulty is that Hypertensive Vascular Disease with all its possible complications--heart disease, kidney disease, stroke, blindness--is still treated very casually, a striking contrast to the attitude toward cancer. Since patients, physicians, and the chemical industry prefer the taking, prescribing, and selling of drugs to a treatment inconvenient to patient and physician and of no benefit to the pharmaceutical industry, the mortality figures for these diseases are still rather appalling."

Despite hundreds of drugs on the market now, high blood pressure remains the #1 cause of death and disability in the world, killing off 9 million people a year. A whole food plant-based diet treats the underlying cause. As Dr. Kempner explained to a patient, "If you should find a heap of manure on your living room floor, I do not recommend that you go buy some Air-Wick [an air freshener] and perfume. I recommend that you get a bucket and shovel and a strong scrubbing brush. Then, when your living room floor is clean again, why, you may certainly apply some Air-Wick if you wish."

As the great physician Maimonides said about 800 years ago, any illness that can be treated by diet alone should be treated by no other means.

For background on this amazing story, see Kempner Rice Diet: Whipping Us Into Shape. He would be proud that there is a whole medical specialty now: Lifestyle Medicine: Treating the Causes of Disease.

This reminds me of the role statin cholesterol-lowering drugs have played in seducing people into the magic bullet approach, but as with all magic it appears to mostly be misdirection:

Introducing the Kempner Rice Diet

Aug16-2.jpg

Franklin Delano Roosevelt brought us through the Great Depression and World War II. Who knows how history would have been different had he not died in his fourth term as President from a massive stroke. In the following days and months, we learned that Roosevelt had suffered from severe high blood pressure for years. In spite of this, he was on no medications or other treatments. The reason for the lack of treatment is stark and simple: there were none. The state of the art at that time was death. Death, from so-called malignant hypertension--out-of-control high blood pressure--for which, it was thought, there was no remedy. But they were wrong. There was Dr. Walter Kempner and his rice-fruit diet.

A physician-scientist, Kempner trained with the best, fled Nazi Germany and set up shop at Duke, where he began treating malignant hypertension patients with a radical diet consisting of only white rice and fruit, with strikingly favorable results: a rapid reduction in blood pressure, rapid improvement in kidney failure, eye pressure, heart failure and other manifestations of this previously fatal illness.

He figured that if a low salt diet helped with blood pressure, a low protein diet helped with kidney function, and a low fat and cholesterol diet helped the heart, why not take it to its logical conclusion and design a no-salt, no cholesterol diet of almost pure carbohydrate. So, he designed a diet with less sodium than any low-sodium diet, less protein than any low-protein diet, and less cholesterol and fat than any other low-fat diet.

His hope was that it would just stop progression of the disease. Instead, something miraculous happened. In about two-thirds of cases, the disease reversed. There were reversals of heart failure, reversals of eye damage, and reversals of kidney failure. At the time, this was effectively a terminal disease where people just had a few months to live, but with Kempner's rice diet, they got better. In my video Kempner Rice Diet: Whipping Us Into Shape, you can see before and after pictures of the back of people's eyes. They started out swollen, bloody and leaking and then were nearly normal in a matter of months.

After being effectively cured by the diet over many months, many patients could then relax the diet to a more conventional plant-based diet and go on to live a normal, active life. The rice diet may actually drop blood pressures too low, so we have to add back other foods to bring the pressures back up to normal.

An editorial in the New England Journal of Medicine described Kempner's results as "little short of miraculous." Practically speaking, there's probably no more effective diet for obese cardiac patients. The problem, though, is that most physicians lack the extraordinary persuasive powers required to keep the patient eating such a restricted diet.

When Dr. Caldwell Esselstyn presented his study results demonstrating in some cases reversal of near end-stage heart disease with a whole food plant-based diet, the Chair of Cleveland Clinic cardiology department asked, "How can we expect patients to stay on a strict diet like this when we can't even get them to quit smoking?" Just like penicillin drugs don't work at all unless we take them, plant-based diets don't work unless we actually eat them.

The answer may be that the physician must have a zealous belief in the diet and must convey that passion to the patients. For Kempner, to keep his patients on the rice diet, he "brow-beat, yelled at, and castigated them when he caught them straying." And he didn't just browbeat them; he sometimes actually beat them. It came out in a lawsuit in which a former patient sued Dr. Kempner, claiming that he had literally whipped her and other patients to motivate them to stick to the diet.

Reminds me of the famous diabetes physician back in the 1800s, Arnoldo Cantani, who knew the remedy for diabetes was not in the drugstore, but rather the kitchen. To ensure compliance, if necessary, he would lock a patient up in a room for six weeks.

Thankfully, in terms of personality, Dr. Esselstyn is the opposite of Dr. Kempner. He is polite, soft-spoken, gentle and able to keep his patients on track without whipping them. And last but not least, Esselstyn walks the talk, following the diet himself, whereas Kempner died of a heart attack (though at the age of 94). Kempner's work continues on in Durham, where they continue a relaxed version of the diet, allowing actual vegetables.

A year before Roosevelt died, Kempner had already published his miraculous results. It seems highly likely that had the rice diet been "provided to President Roosevelt a year before his death, his disease might have been controlled before his fatal stroke, and that this fatal event could have been averted."

Evidence-Based Nutrition

NF-Jan12 Evidence-Based Medicine or Evidence-Biased?.jpg

Dr. Esselstyn's landmark study, demonstrating that even advanced triple vessel coronary artery disease could be reversed with a plant-based diet, has been criticized for being such a small study. But the reason we're used to seeing large studies is that they typically show such small effects. Drug manufacturers may need to study 7,000 people in order to show a barely statistically significant 15% drop in ischemic events in a subsample of patients. Esselstyn achieved a 100% drop in those who stuck to his diet, all the more compelling considering that those 18 participants experienced 49 coronary events (like heart attacks) in the eight years before they went on the diet. These patients were the sickest of the sick, most of whom having already failed surgical intervention. When the effects are so dramatic, how many people do you need?

Before 1885, a symptomatic rabies infection was a death sentence, until little Joseph Meister became the first to receive Pasteur's experimental rabies vaccine. The results of this and one other case were so dramatic compared with previous experience that the new treatment was accepted with a sample size of two. That is, the results were so compelling that no randomized controlled trial was necessary. Having been infected by a rabid dog, would you be willing to participate in a randomized controlled trial, when being in the control group had a certainty of a ''most awful death''? Sadly, such a question is not entirely rhetorical.

In the 1970's, a revolutionary treatment for babies with immature lungs called "extracorporeal membranous oxygenation" (ECMO), transformed immature lung mortality from 80% dead to 80% alive nearly overnight. The standard therapy caused damage to infants' lungs and was a major cause of morbidity and mortality in infants. ECMO is much gentler on babies' lungs, "providing life support while allowing the lungs to 'rest.'"

Despite their dramatic success, the researchers who developed ECMO felt forced to perform a randomized controlled trial. They didn't want to; they knew they'd be condemning babies to death. They felt compelled to perform such a trial because their claim that ECMO worked would, they judged, carry little weight amongst their medical colleagues unless supported by a randomized controlled trial. Therefore, at Harvard's Children's Hospital, 39 infants were randomized to either get ECMO or conventional medical therapy. The researchers decided ahead of time to stop the trial after the 4th death so as not to kill too many babies. And that's what they did. The study was halted after the fourth conventional medical therapy death, at which point nine out of nine ECMO babies had survived. Imagine being the parent to one of those four children.

Similarly, imagine being the child of a parent who died other conventional medical or surgical therapy for heart disease.

In her paper "How evidence-based medicine biases physicians against nutrition," Laurie Endicott Thomas reminds us that medical students in the United States are taught very little about nutrition (See Evidence-Based Medicine or Evidence-Biased?). Worse yet, according to Thomas, their training actually biases them against the studies that show the power of dietary approaches to managing disease by encouraging them to ignore any information that does not come from a double-blind, randomized controlled trial. Yet humans cannot be blinded to a dietary intervention--we tend to notice what we're eating--and, as a result, physicians are biased in favor of drug treatments and against dietary interventions for the management of chronic disease.

Evidence-based medicine is a good thing. However, Thomas points out that the medical profession may be focusing too much on one type of evidence to the exclusion of all others. Unfortunately, this approach can easily degenerate into "ignoring-most-of-the-truly-important-evidence" based medicine.

Heart disease is a perfect example. On healthy enough plant based diets, our number one cause of death may simply cease to exist. The Cornell-Oxford-China Study showed that even small amounts of animal-based food was associated with a small, but measurable increase in the risk of some chronic diseases. In other words, "the causal relationship between dietary patterns and coronary artery disease was already well established before Dean Ornish and Caldwell Esselstyn undertook their clinical studies." The value of their studies was not so much in providing evidence that such a dietary change would be effective, but in showing that "physicians can persuade their patients to make such changes," and in "providing interesting data on the speed and magnitude of the change in severe atherosclerotic lesions as a result of dietary therapy."

Therefore, any complaints that these studies were small or unblinded are simply irrelevant. Because the evidence of the role of diet in causing atherosclerosis is already so overwhelming, "assigning a patient to a control group eating the standard American diet could be considered a violation of research ethics."

Evidence of the value of plant-based diets for managing chronic disease has been available in the medical literature for decades. Walter Kempner at Duke University, John McDougall, the Physician's Committee for Responsible Medicine, Nathan Pritikin, and Denis Burkitt all warned us that the standard Western diet is the standard cause of death and disability in the Western world. Yet physicians, especially in the US, are still busily manning the ambulances at the bottom of the cliff instead of building fences at the top.

If you're not familiar with Dr. Esselstyn's work, I touch on it in:

Sadly, medical students learn little about these powerful tools:

Dr. Greger’s 2015 Live Year-in-Review Presentation

Food as Medicine

View my new live presentation here: Food as Medicine: Preventing and Treating the Most Dreaded Diseases with Diet

Every year I scour the world's scholarly literature on clinical nutrition, pulling together what I find to be the most interesting, practical, and groundbreaking science on how to best feed ourselves and our families. I start with the thousands of papers published annually on nutrition (27,000 this year--a new record!) and, thanks to a crack team of volunteers (and now staff!), I'm able to whittle those down (to a mere 8,000 this year). They are then downloaded, categorized, read, analyzed, and churned into the few hundred short videos. This allows me to post new videos and articles every day, year-round, to NutritionFacts.org. This certainly makes the site unique. There's no other science-based source for free daily updates on the latest discoveries in nutrition. The problem is that the amount of information can be overwhelming.

Currently I have more than a thousand videos covering 1,931 nutrition topics. Where do you even begin? Many have expressed their appreciation for the breadth of material, but asked that I try to distill it into a coherent summary of how best to use diet to prevent and treat chronic disease. I took this feedback to heart and in 2012 developed Uprooting the Leading Causes of Death, which explored the role diet may play in preventing, arresting, and even reversing our top 15 killers. Not only did it rise to become one of the Top 10 Most Popular Videos of 2012, it remains my single most viewed video to date, watched over a million times (NutritionFacts.org is now up to more than 1.5 million hits a month!).

In 2013 I developed the sequel, More Than an Apple a Day, in which I explored the role diet could play in treating some of our most common conditions. I presented it around the country and it ended up #1 on our Top 10 Most Popular Videos of 2013. Then in 2014 I premiered the sequel-sequel, From Table to Able, in which I explored the role diet could play in treating some of our most disabling diseases, landing #1 on our Top 10 Most Popular Videos of 2014.

Every year I wonder how I'm going to top the year before. Knowing how popular these live presentations can be and hearing all the stories from folks about what a powerful impact they can have on people's lives, I put my all into this new 2015 one. I spent more time putting together this presentation than any other in my life. It took me an entire month, and when you see it I think you'll appreciate why.

This year, I'm honored to bring you Food as Medicine, in which I go through our most dreaded diseases--but that's not even the best part! I'm really proud of what I put together for the ending. I spend the last 20 minutes or so (starting at 56:22) going through a thought experiment that I'm hoping everyone will find compelling. I think it may be my best presentation ever. You be the judge.

You can watch it at no cost online, but it is also available on DVD through my website or on Amazon. If you want to share copies with others, I have a five for $40 special (enter coupon code 5FOR40FAM). All proceeds from the sales of all my books, DVDs, downloads, and presentations go to the 501c3 nonprofit charity that keeps NutritionFacts.org free for all, for all time.
