Rice diet

Last updated

The Rice Diet started as a radical treatment for malignant hypertension before the advent of antihypertensive drugs; the original diet included strict dietary restriction and hospitalization for monitoring. Some contemporary versions have been greatly relaxed, and have been described as fad diets.

Origin and original form

The Rice Diet Program was founded in 1939 by Walter Kempner  [ de ] (1903-1997), a German physician and refugee from the Nazis, who was at that time associated with Duke University. [1] [2] Kempner had many patients with malignant hypertension with kidney failure, and there were no good treatments for those patients. He believed that the kidney had two functions, one excretory and the other metabolic, and "he theorized that if the protein and electrolyte load on the kidney was reduced to a minimum, the kidney might better perform its more essential metabolic role. The details of his reasoning are obscure, but he began to treat patients with malignant hypertension with a diet composed of nothing but rice and fruit, and amazingly, they rapidly improved." [1]

Kempner's implementation was very strict, but also careful - patients were hospitalized for several weeks at the beginning of treatment. The initial treatment was stopping all medication and putting the patient on a diet consisting of "white rice, sugar, fruit, fruit juices, vitamins and iron, and provided about 2000 calories, 20 grams of protein, and 700–1000 ml of liquid as fruit juices. Sodium content was extremely low, about 150 milligrams per day, and chloride content about 200 milligrams per day." If results were good, after several months small amounts of lean meat and vegetables were added to the diet.

Kempner obtained remarkable results, and he was invited to present them at a meeting of the New York Academy of Medicine in 1946. His presentation survives and "presents clear and unambiguous evidence, including blood pressure charts, retinal photographs, chest radiographs, electrocardiograms and laboratory results, documenting the benefits of his diet." [1] [upper-alpha 1]

Kempner described his diet as "a monotonous and tasteless diet which would never become popular.... Kempner's only defense of its use was the fact that “it works,” and that the diet was preferable to the alternative of certain death" [1]

Controversy

Kempner admitted in statements before his death that he whipped patients who avoided his rice diet. In 1993, a former patient Sharon Ryan sued him. [3] Ryan accused Kempner of keeping her as a "virtual sex slave" for nearly two decades. [3] According to the lawsuit, Kempner "persuaded Ryan to drop out of college, moved her into a home he owned, hired her to work for the clinic, and maintained a sexual relationship with Ryan by isolating her from the outside world". [4] The lawsuit ended with a confidential settlement. [5] In 1997, the Raleigh News & Observer reported that, by 1975, Duke University Medical Center (now Duke University Hospital), knew that Kempner had used a riding crop on several patients and reprimanded him, though he continued to be associated with the university. [4] None of these charges were proven in court. Dr Kempner denied the accusations of having a sexual relationship with this patient. [6] " Dr Kempner had whipped this patient on several occasions, and had also whipped several other patients in an effort to motivate them. In all instances, the patients had either themselves suggested or had consented in advance to this punishment for breaking the diet" [7] These events received a great deal of sensationalist media attention.

Contemporary forms

Kempner retired from the Duke Faculty in 1974, but consulted until 1992. The commercialization of drugs to treat hypertension reduced both demand for the program and the need to make it strict in order to prevent death. In 2002 the program became independent of Duke University, and in 2013 the Rice House Healthcare Program opened in Durham, North Carolina. [1] The Rice House Healthcare Program is an inpatient facility where people are put on a diet akin to the original diet and are monitored. [8]

The rice diet has influenced some contemporary advocates of the plant-based diet. For example, physician John A. McDougall has commented regarding the research of Walter Kempner that "all who have followed in his footsteps, including Nathan Pritikin, Dean Ornish, Neal Barnard, Caldwell Esselstyn, and myself, owe homage to this man and his work." [9]

The rice diet has been popularized in a modulated form through several modern books. Judy Moscovitz in her book The Rice Diet Report, allows fruit, vegetables and various carbohydrates. [10] Kitty and Robert Rosati authors of The Rice Diet Solution describe their diet as a "low-sodium, good-carb, detox diet". It is based on the consumption of carbohydrates such as whole grains, fruits, vegetables, and beans. [11]

Criticism

The modern version of the rice diet has been categorized as a fad diet with possible disadvantages including a boring food choice, flatulence, and the risk of feeling too hungry. [12]

Most people cannot follow the rice diet over extended periods, as it is too restrictive. Loren Cordain has commented that "the tenets of the Rice Diet are inconsistent with the best science of the 21st century". [13]

Nutritionist Yvette Quantz has suggested that although the rice diet has some good short-term benefits in the long term it does not provide "enough calories or protein for most people to sustain." [14]

Notes

  1. "In Kempner’s original cohort of 192 people, 25 patients died. Of the remaining 167, 60 patients did not substantially improve their blood pressure values. However, 107 patients showed significant improvement (from 200/112 mmHg to 149/96 mmHg) with the diet. Heart size decreased in 66 of 72 patients. Serum cholesterol was reduced in 73 of 82 patients. Retinopathy was reduced or disappeared completely in 21 of 33 patients. We must keep these results in context with the times, during which the life expectancy of anyone with malignant hypertension was 6 months." [2]

Nephrology is a specialty of adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function and kidney disease, the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal replacement therapy. The word "renal" is an adjective meaning "relating to the kidneys", and its roots are French or late Latin. Whereas according to some opinions, "renal" and "nephro" should be replaced with "kidney" in scientific writings such as "kidney medicine" or "kidney replacement therapy", other experts have advocated preserving the use of renal and nephro as appropriate including in "nephrology" and "renal replacement therapy", respectively.

Kidney failure, also known as end-stage kidney disease, is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney failure, which develops slowly and can often be irreversible. Symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications of acute and chronic failure include uremia, hyperkalaemia, and volume overload. Complications of chronic failure also include heart disease, high blood pressure, and anaemia.

A dietitian, medical dietitian, or dietician is an expert in identifying and treating disease-related malnutrition and in conducting medical nutrition therapy, for example designing an enteral tube feeding regimen or mitigating the effects of cancer cachexia. Many dietitians work in hospitals and usually see specific patients where a nutritional assessment and intervention has been requested by a doctor or nurse, for example if a patient has lost their ability to swallow or requires artificial nutrition due to intestinal failure. Dietitians are regulated healthcare professionals licensed to assess, diagnose, and treat such problems. In the United Kingdom, dietitian is a 'protected title', meaning identifying yourself as a dietitian without appropriate education and registration is prohibited by law.

Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates are limited, and replaced with foods containing a higher percentage of fat and protein, as well as low carbohydrate foods.

A low-protein diet is a diet in which people decrease their intake of protein. A low-protein diet is used as a therapy for inherited metabolic disorders, such as phenylketonuria and homocystinuria, and can also be used to treat kidney or liver disease. Low protein consumption appears to reduce the risk of bone breakage, presumably through changes in calcium homeostasis. Consequently, there is no uniform definition of what constitutes low-protein, because the amount and composition of protein for an individual with phenylketonuria would differ substantially from one with homocystinuria or tyrosinemia.

Kidney disease, or renal disease, technically referred to as nephropathy, is damage to or disease of a kidney. Nephritis is an inflammatory kidney disease and has several types according to the location of the inflammation. Inflammation can be diagnosed by blood tests. Nephrosis is non-inflammatory kidney disease. Nephritis and nephrosis can give rise to nephritic syndrome and nephrotic syndrome respectively. Kidney disease usually causes a loss of kidney function to some degree and can result in kidney failure, the complete loss of kidney function. Kidney failure is known as the end-stage of kidney disease, where dialysis or a kidney transplant is the only treatment option.

<span class="mw-page-title-main">Hereditary fructose intolerance</span> Medical condition

Hereditary fructose intolerance (HFI) is an inborn error of fructose metabolism caused by a deficiency of the enzyme aldolase B. Individuals affected with HFI are asymptomatic until they ingest fructose, sucrose, or sorbitol. If fructose is ingested, the enzymatic block at aldolase B causes an accumulation of fructose-1-phosphate which, over time, results in the death of liver cells. This accumulation has downstream effects on gluconeogenesis and regeneration of adenosine triphosphate (ATP). Symptoms of HFI include vomiting, convulsions, irritability, poor feeding as a baby, hypoglycemia, jaundice, hemorrhage, hepatomegaly, hyperuricemia and potentially kidney failure. While HFI is not clinically a devastating condition, there are reported deaths in infants and children as a result of the metabolic consequences of HFI. Death in HFI is always associated with problems in diagnosis.

<span class="mw-page-title-main">Nephritic syndrome</span> Medical condition

Nephritic syndrome is a syndrome comprising signs of nephritis, which is kidney disease involving inflammation. It often occurs in the glomerulus, where it is called glomerulonephritis. Glomerulonephritis is characterized by inflammation and thinning of the glomerular basement membrane and the occurrence of small pores in the podocytes of the glomerulus. These pores become large enough to permit both proteins and red blood cells to pass into the urine. By contrast, nephrotic syndrome is characterized by proteinuria and a constellation of other symptoms that specifically do not include hematuria. Nephritic syndrome, like nephrotic syndrome, may involve low level of albumin in the blood due to the protein albumin moving from the blood to the urine.

Liddle's syndrome, also called Liddle syndrome, is a genetic disorder inherited in an autosomal dominant manner that is characterized by early, and frequently severe, high blood pressure associated with low plasma renin activity, metabolic alkalosis, low blood potassium, and normal to low levels of aldosterone. Liddle syndrome involves abnormal kidney function, with excess reabsorption of sodium and loss of potassium from the renal tubule, and is treated with a combination of low sodium diet and potassium-sparing diuretics. It is extremely rare, with fewer than 30 pedigrees or isolated cases having been reported worldwide as of 2008.

Cystic kidney disease refers to a wide range of hereditary, developmental, and acquired conditions and with the inclusion of neoplasms with cystic changes, over 40 classifications and subtypes have been identified. Depending on the disease classification, the presentation may be at birth, or much later into adult life. Cystic disease may involve one or both kidneys and may, or may not, occur in the presence of other anomalies. A higher incidence is found in males and prevalence increases with age. Renal cysts have been reported in more than 50% of patients over the age of 50. Typically, cysts grow up to 2.88 mm annually and may cause related pain and/or hemorrhage.

The Dietary Approaches to Stop Hypertension or the DASH diet is a diet to control hypertension promoted by the U.S.-based National Heart, Lung, and Blood Institute, part of the National Institutes of Health (NIH), an agency of the United States Department of Health and Human Services. The DASH diet is rich in fruits, vegetables, whole grains, and low-fat dairy foods. It includes meat, fish, poultry, nuts, and beans, and is limited in sugar-sweetened foods and beverages, red meat, and added fats. In addition to its effect on blood pressure, it is designed to be a well-balanced approach to eating for the general public. DASH is recommended by the United States Department of Agriculture (USDA) as a healthy eating plan. The DASH diet is one of three healthy diets recommended in the 2015–20 U.S. Dietary Guidelines, which also include the Mediterranean diet and a vegetarian diet. The American Heart Association (AHA) considers the DASH diet "specific and well-documented across age, sex and ethnically diverse groups."

Prehypertension, also known as high normal blood pressure and borderline hypertensive (BH), is a medical classification for cases where a person's blood pressure is elevated above optimal or normal, but not to the level considered hypertension. Prehypertension is now referred to as "elevated blood pressure" by the American College of Cardiology (ACC) and the American Heart Association (AHA). The ACC/AHA define elevated blood pressure as readings with a systolic pressure from 120 to 129 mm Hg and a diastolic pressure under 80 mm Hg, Readings greater than or equal to 130/80 mm Hg are considered hypertension by ACC/AHA and if greater than or equal to 140/90 mm Hg by ESC/ESH. and the European Society of Hypertension defines "high normal blood pressure" as readings with a systolic pressure from 130 to 139 mm Hg and a diastolic pressure 85-89 mm Hg.
