Tomatoes, Potatoes May Aggravate Arthritis Symptoms

You don’t need years of research to tell you that diet affects arthritis symptoms and arthritis progression. I have reported on many of these foods here. But one family of foods that I was unaware could affect arthritis symptoms is called the nightshades. Foods in the nightshade family include tomatoes, potatoes, eggplant, tobacco and peppers.

Dr. Norman F. Childers, Ph.D. of Rutgers University and the Institute of Food and Agricultural Sciences at the University of Florida has conducted several studies over the last 30 years into the relationship between nightshades and the most common forms of arthritis – osteoarthritis and rheumatoid arthritis.

One of the earliest was in response to a book written by Dr. Childers in 1977. This 1979 survey of 2453 book holders resulted in 763 being involved in the study. Of these, 44% indicated a positive response to the “No Nightshades Diet” and an additional 28% reported a marked positive improvement. Characteristics of the marked improvement included: immobile joints becoming mobile; use of canes, walkers and wheelchairs discontinued. 7% of the participants reported no improvements and the remainder were determined to have not followed the diet.

Another book, published by Dr. Childers in 1981 resulted in another book holder survey in 1986. 434 people completed a detailed 4-page questionnaire. This survey found that 85% had been diagnosed with arthritis by a physician. 79% were treating their arthritis with drugs, most of whom were experiencing some relief. Of the 182 respondents who indicated they were rigidly following the diet, 94% said they experienced complete or substantial relief from their symptoms. Of the other 252 respondents reported an occasional “slip”, half reported complete or substantial relief. Over all, 68% had experienced complete or substantial relief on their arthritis symptoms.

Additional studies have been conducted at Rutgers University with rats. One study, conducted in 1979, attempted to determine if the white potato can produce vitamin D3. Results showed that low levels of potato increased bone mineralization which is believed to be due to increased intestinal absorption of calcium, phosphorus and magnesium. A high intake of potato resulted in soft tissue mineralization, decreased bone mineral content and decrease in body weight gain. The overall effect indicated the potato does have vitamin D-like activity.
