DIETS CAN CURE: THE RESEARCH

Treatment of arthritis with diet became fashionable in the 1920s and many studies over the last 20 years have shown a healthy diet, one very different from the typical American diet, can be a very effective treatment of inflammatory arthritis for many people.

Ÿ In 1979, Skoldstam fasted 16 patients with rheumatoid arthritis for 7-10 days with a fruit-and vegetable juice fast, followed by a lactovegetarian diet for 9 weeks. One-third of the patients improved during the fast, but all deteriorated when the milk products were reintroduced (a lactovegetarian diet) (Scan J Rheumatol 8:249, 1979).

Ÿ In 1980, Hicklin reported clinical improvement in 24 of 72 rheumatoid patients on an exclusion diet. Food sensitivities were reported to: grains in 14, milk in 4, nuts in 8, beef in 4, cheese in 7, eggs in 5, and one each to chicken, fish, potato, and liver (Clin Allergy 10:463, 1980).

Ÿ In 1980, Stroud reported on 44 patients with rheumatoid arthritis treated with the elimination of food and chemical avoidance. They were then challenged with foods. Wheat, corn, and beef were the greatest offenders (Clin Res 28:791A, 1980).

Ÿ In 1981, Parke described a 38-year-old mother with 11-years of progressive erosive seronegative rheumatoid arthritis who recovered from her disease, attaining full mobility, by stopping all dairy products. She was then hospitalized and challenged with 3 pounds of cheese and seven pints of milk over 3 days. Within 24 hours there was a pronounced deterioration of the patient’s arthritis (BMJ 282:2027, 1981).

Ÿ In 1981, Lucas found a fat-free diet produced complete remission in 6 patients with rheumatoid arthritis. Remission was lost within 24-72 hours of eating a high-fat meal, such as one containing chicken, cheese, safflower oil, beef, or coconut oil. The authors concluded, "...dietary fats in amounts normally eaten in the American diet cause the inflammatory joint changes seen in rheumatoid arthritis." (Clin Res 29:754, 1981).

Ÿ In 1982 Sundqvist studied the influence of fasting with 3 liters of fruit and vegetable juice daily and lactovegetarian diet on intestinal permeability in 5 patients with rheumatoid arthritis. Intestinal permeability decreased after fasting, but increased again during a subsequent lactovegetarian diet regime (dairy products and vegetables). Concomitantly it appeared that disease activity first decreased and then increased again. The authors conclude, "The results indicate that, unlike a lactovegetarian diet, fasting may ameliorate the disease activity and reduce both the intestinal and the non-intestinal permeability in rheumatoid arthritis." (Scand J Rheumatol 11:33, 1982.)

Ÿ In 1983, Lithell studied twenty patients with arthritis and various skin diseases on a metabolic ward during a 2-week period of modified fast on vegetarian broth and drinks, followed by a 3-week period of a vegan diet (no animal products). During fasting, joint pains were less intense in many subjects. In some types of skin diseases (pustulosis palmaris et plantaris and atopic eczema) an improvement could be demonstrated during the fast. During the vegan diet, both signs and symptoms returned in most patients, with the exception of some patients with psoriasis who experienced an improvement. The vegan diet was very high-fat (42% fat). (Acta Derm Venereol 63:397, 1983).

Ÿ In 1984 Kroker described 43 patients from three hospital centers who underwent a 1-week water fast, and overall the group improved significantly during the fast. In 31 patients evaluated, 25 had "fair" to "excellent" responses and 6 had "poor" responses. Those with more advanced arthritis had the poor responses. (Clin Ecol 2:137, 1984).

Ÿ In 1985, Ratner removed all dairy products from the diet of patients with seronegative rheumatoid arthritis, 7 out of 15 went into remission when switched to milk-free diets (Isr J Med Sci 21:532, 1985)

Ÿ In 1986, Panush described a challenge of milk in a 52-year-old white woman with 11 years of active disease with exacerbations allegedly associated with meat, milk, and beans. After fasting (3 days) or taking Vivonex (2 days) there was no morning stiffness or swollen joints. Challenges with cow’s milk (blinded in a capsule) brought all of her pain, swelling and stiffness back (Arthritis Rheum 29:220, 1986).

Ÿ In 1986, Darlington published a 6-week, placebo-controlled, single-blinded study on 48 patients. Forty-one patients identified foods producing symptoms. Cereal foods, such as corn and wheat gave symptoms in more than 50% of patients (Lancet 1:236, 1986).

Ÿ In 1986, Hanglow performed a study of the comparison of the arthritis-inducing properties of cow's milk, egg protein and soy milk in experimental animals. The 12-week cow's milk feeding regimen produced the highest incidence of significant joint lesions. Egg protein was less arthritis-inducing than cow's milk, and soy milk caused no reaction. (Int Arch Allergy Appl Immunol 80:192, 1986).

Ÿ In 1987, Wojtulewski reported on 41 patients with rheumatoid arthritis treated with a 4-week elimination diet. Twenty-three improved. (Food allergy and intolerance. London: Bailliere Tindall 723, 1987).

Ÿ In 1988, Beri put 14 patients with rheumatoid arthritis on a diet free from pulses, cereals, milk, and non-vegetarian protein foods. Ten (71%) showed significant clinical improvement. Only three patients (11%) adhered to the diet for a period of 10 months (Ann Rheum Dis 47:69, 1988.)

Ÿ In 1988, Hafstrom fasted 14 patients with water only for one week. During fasting the duration of morning stiffness, and number and size of swollen joints decreased in all 14 patients. No adverse effects of fasting were seen except transient weakness and lightheadedness. The authors consider fasting as one possible way to induce rapid improvement in rheumatoid arthritis (Arthritis Rheum 31:585, 1988).

Ÿ In 1991, Kjeldsen-Kragh put 27 patients on a modified fast with vegetable broths, followed by a vegan diet, and then a lacto-ovovegetarian diet. Significant improvement occurred in objective and subjective parameters of their disease (Lancet 2:899, 1991) A two-year follow-up examination found all diet responders but only half of the diet nonresponders still following the diet, further indicating that a group of patients with rheumatoid arthritis benefit from dietary manipulations and that the improvement can be sustained through a two-year period (Clin Rheumatol 13:475, 1994.) Patients dropping out with arthritic flares in the diet group left the study mainly when the lactovegetarian diet (dairy products) were introduced (Lancet 338:1209, 1991).

Ÿ In 1991 Darlington reported on 100 patients who had undergone dietary manipulation therapy in the past decade, one-third were still well and controlled on diet alone without any medication up to 7 years after starting the diet treatment. They found most patients reacted to cereals and dairy products (Lancet 338:1209, 1991).

Ÿ In 1991, Skoldstam fasted 15 patients for 7 to 10 days. Almost all of the patients showed remarkable improvement. Many patients felt the return of pain and stiffness on the day after returning to their "normal" eating and all benefit was lost after a week (Rheum Dis Clin North Am 17:363, 1991).

Ÿ In 1992, Sheignalet reported on 46 adults with rheumatoid arthritis who eliminated dairy products and cereals. Thirty-six patients (78%) responded favorably with 17 clearly improved, and 19 in complete remission for one to five years. Eight of those 19 stopped all medications with no relapse. Favorable benefits appeared before the end of the third month in 32 of the patients (Lancet 339:68, 1992).

Ÿ In 1992, van de Laar showed benefits of a hypoallergenic, artificial diet in six rheumatoid patients. Placebo controlled rechallenges showed intolerance for specific foodstuffs in four patients. In two patients, biopsy of the joints showed specific (IgE) antibodies to certain foods (Ann Rheum Dis 51:303, 1992).

Ÿ In 1992, Shigemasa reported a 16-year-old girl with lupus who changed to a pure vegetarian diet (no animal foods) and stopped her steroids without her doctor’s permission. After starting the diet her antibody titers (a reflection of disease activity) fell to normal and her kidney disease improved (Lancet 339:1177, 1992).

Ÿ In 1995, Kavanaghi showed an elemental diet (which is an hypoallergenic protein-free artificial diet consisting of essential amino acids, glucose, trace elements and vitamins) when given to 24 patients with rheumatoid arthritis improved their strength and arthritic symptoms. Reintroduction of food brought the old symptoms back (Br J Rheumatol 34:270, 1995).

Ÿ In 1998, Nenonen tested the effects of an uncooked vegan diet, rich in lactobacilli, in rheumatoid patients randomized into diet and control groups. The intervention group experienced subjective relief of rheumatic symptoms during intervention. A return to an omnivorous diet aggravated symptoms. The results showed that an uncooked vegan diet, rich in lactobacilli, decreased subjective symptoms of rheumatoid arthritis (Br J Rheumatol 37:274, 1998).

 

IT’S THE WHOLE DIET

The importance of the overall diet cannot be overemphasized. Proper foods keep the intestinal barriers strong and the immune system in a fighting condition. Those foods are whole starches, vegetable, and fruits. In addition to being free of animal products, the diet must be low in fat of all kinds--vegetable oil (even olive oil, corn, safflower, and flaxseed oil) and animal fat. When it comes to blaming individual foods, dairy products seem to be the most troublesome foods, causing the most common and severe reactions. Many reports indicate grains, such as corn and wheat can also aggravate of symptoms. The truth seems to be almost any food can cause trouble, but few people react to vegetable foods.

My experience and this research has lead me to prescribe for the past 22 years a starch-based diet with the addition of fruits, and vegetables (low-fat and devoid of all animal products). If no improvement is seen within 2 weeks, I suggest wheat and corn be eliminated. The final step is to follow an elimination diet based on the foods least likely to cause problems, such as sweet potatoes and brown rice with the addition of noncitrus fruits, and green and yellow vegetables. All thoroughly cooked. Water is the beverage. If improvement is found (usually within 1 to 2 weeks), then foods are added back one at a time to see if there is an adverse reaction. (A complete description of this diet can be found in the McDougall Program--12 days to Dynamic Health). Nonsteroidal antiinflammatory drugs should be stopped, and if necessary, replaced by aspirin or nabumetone (Relafen). Other medications are reduced and/or discontinued as the symptoms improve.

I have just finished a study on 28 patients with rheumatoid arthritis using the McDougall Diet (with corn and wheat included) and the results were remarkable. Full publication will appear this fall.

FOR WHOLE BODY BENEFITS

By no small coincidence the same diet that keeps the joints healthy also keeps the rest of the body sound. Diane of Walnut Creek wrote to me last year. "I had what I can only call a miserable life until about five years ago. Nothing seemed to go right for me. In late 1991 I was diagnosed with spinal stenosis and degenerative arthritis. I was declared permanently disabled and left my job as a daily newspaper journalist. My therapist gave me a wonderful gift--she suggested I try your program. I shrugged off her suggestion at first. I swore that I ate well anyway: only dairy and shellfish and white meats. Only! She did not push the point, wisely waiting for me to think about the idea. I did wait for two years. Then two years ago she suggested your program again. I told her I didn’t believe it would work, but agreed to try it for two months. I was overweight, very overweight, by 100 pounds, most of my life--carrrying all that poundage caused a lot of wear on my joints. That was two years ago, and I’m a lifelong convert."

"Of course what you predicted happened: My migraines went away completely; I stopped swelling in my joints; I could sleep easily; I had no indigestion problems of any kind; and I began to drop weight. As you probably know, it was a lot easier than I thought it would be. Before I started the McDougall plan, I was losing weight slowly. Afterward, the weight loss was dramatic. After about six months, people started noticing and commenting. They kept saying things like ‘you look ten years younger,’ or most often, ‘You look great. What did you do?’ I no longer take the anti-inflammatory drugs and painkillers that I was taking before the McDougall way. My knee and low-back are virtually pain-free. Now, what I’ve found is that nobody believes it can be as simple as eating carefully and exercising. They all want some magic or some pill."
