Nightshade Vegetables Are Part of a Plant Family Called Solanaceae WHAT ARE “NIGHTSHADE” VEGETABLES? Nightshade vegetables are part of a plant family called Solanaceae. The main plants in the Nightshade family are tomatoes, potatoes (but not sweet potato/yams), eggplant, peppers (all except black pepper), paprika, tobacco, gogi berries and ashwagandha. I recommend some of my patients do a trial of a diet free of nightshade vegetables for a period of time to determine if they notice any improvements in their health. Read on to find out why I recommend this to some patients. NIGHTSHADE VEGETABLES In the 1950’s, Norman F. Childers, a professor of horticulture at Rutgers University, began to investigate the relationship between nightshade plants and arthritic as well as other medical conditions. His work involved examining naturally occurring toxins in food plants. Childers’ specific interest in the nightshade group of plants stemmed from his own experience with consumption of members of the Solanaceae (or nightshade) family. This group of plants includes: tomatoes, potatoes (except sweet potatoes and yams), eggplant, peppers (all except black and white pepper), paprika, the herb ashwagandha, goji berries and tobacco, as well as other plants that are not generally part of the human diet. Childers noticed that his diverticulitis (condition involving the intestinal wall) symptoms, and later his arthritis pain, disappeared when he avoided the nightshade foods. After some of his colleagues and acquaintances had similar relief of chronic symptoms by following the “nightshade-free” diet, Childers decided to recruit volunteers across the country to try his diet. Much of the academic work regarding nightshades can be credited to Dr. Norman Childers who had been researching nightshades for about 50 years in farm animals, as well as through dietary modification techniques with human correspondents across the country. In 1977, Childers and one of his students, Gerald M. Russo, published the first edition of The Nightshades and Health, which describes this association between nightshades and various chronic health ailments such as structural and arthritic type conditions. Childers included numerous abstracts in his book that describe the effects of nightshade plant consumption on livestock, such as: gait abnormalities, weakness, osteopetrosis, calcinosis and arterial calcification. He also includes several detailed case reports from the human correspondents who followed his prescribed diet and their experiences involving relief of chronic ailments. Most of the studies involving the ill-effects of chronic solanine/nightshade plant ingestion involve animals. However, Dr. Childers did record the case histories and results that a nightshade free diet had on over 400 correspondents that chose to try it in an attempt to relieve their chronic arthritis. The following is a summary of the report issued by Dr. Childers and one of his colleagues: Total of 434 correspondents who returned questionnaire issued related to diagnosis of arthritis and their willingness to attempt elimination of nightshades as a form of treatment. Of those rigidly on the diet, 94% had complete or substantial relief of symptoms. Of dieters with occasional “slip”, 50% had complete or substantial relief of symptoms. Overall, 68% had complete or substantial relief. Childers’ case histories also emphasized the fact that transgressions in the diet can often result in a recurrence of symptoms. In addition to arthritic conditions, I find that nightshade consumption in some individuals can also be associated with gastrointestinal symptoms, skin issues, and other chronic pain disorders, amongst other manifestations. To determine if nightshade vegetables are affecting your health, you need to stay off all nightshades (potato, except for sweet potato/yam, tomato, eggplant, pepper except for black/white pepper, paprika, tobacco, ashwagandha, and goji berries) for at least 6-8 weeks. Some patients may feel better within days, while it can take months for others to realize the full benefit of avoidance. You should read labels carefully and have 100% avoidance for optimal results (if a label says “spices” and doesn’t say what kind, assume it has paprika or red pepper unless you check with the manufacturer). After several weeks to months, if feeling better, try adding back small amounts of nightshades and see how you feel. For many patients, permanent avoidance is necessary to keep symptoms at bay; however, there are patients who can introduce small quantities back into the diet without suffering from a relapse of symptoms.

The method is based on a generic solid-phase extraction procedure, using three sorbent phases in two cartridges that are connected in series, hence covering a wide range of polarities, followed by liquid chromatography coupled to high-resolution mass spectrometry. The acquisition was performed in the full-scan and data-dependent modes while working under positive and negative ionisation conditions. This method was applied in order to assess the natural toxins in the Ter River water reservoirs, which are used to produce drinking water for Barcelona city (Spain). The study was carried out during a period of seven months, covering the expected prior, during, and post-peak blooming periods of the natural toxins. Fifty-three (53) compounds were tentatively identified, and nine of these were confirmed and quantified. Phytotoxins were identified as the most frequent group of natural toxins in the water, particularly the alkaloids group.

  • Alpha-Tomatine Content in Tomato and Tomato Products Determined By
    J. Agric. Food Chem. 1995, 43, 1507-151 1 1507 a-Tomatine Content in Tomato and Tomato Products Determined by HPLC with Pulsed Amperometric Detection Mendel Friedman* and Carol E. Levin Food Safety and Health Research Unit, Western Regional Research Center, Agricultural Research Service, U.S. Department of Agriculture, 800 Buchanan Street, Albany, California 94710 Tomato plants (Lycopersicon esculentum) synthesize the glycoalkaloid a-tomatine, possibly as a defense against insects and other pests. As part of an effort to improve the safety of plant foods, the usefulness of a new HPLC pulsed amperometric detection (PAD) method for the direct analysis of a-tomatine in different parts of the tomato plant; in store-bought and field-grown, including transgenic, tomatoes; in a variety of commercial and home-processed tomato products; and in eggplant and tomatillos was evaluated. The method was found to be useful for analysis of a variety of products including high-tomatine calyxes, flowers, leaves, roots, and stems of the tomato plant (14-130 mg/100 g of fresh weight), low-tomatine red tomatoes (0.03-0.08 mg/100 g), intermediate- tomatine tomatoes (0.1-0.8 mg/100 g), and high-tomatine fresh and processed green, including pickled and fried, tomatoes (0.9-55 mg/100 g). No experimental difficulties were encountered with extraction and analysis of tomatine in complex foods such as tomato juice, ketchup, salsa, sauce, and sun-dried tomatoes. Microwaving and frying did not significantly affect tomatine levels of tomato foods. The tomatine content of fresh market and transgenic delayed-ripening varieties was not different from the range ordinarily seen in tomato.

  • Food Borne Diseases
    204 Food Science 19 Food Borne Diseases While food is necessary for sustaining life, it could also be a cause of illness. There is a general misconception that if a food is ‘natural’, it must be ‘safe’. Unfortunately the fact that many toxins occur in natural plant foods, falsifies this naïve view. Most of these endogenous toxins are in plant foods and a few in animal foods. Toxins from Plants Solanine of potatoes is one of the best known plant toxins. It is a steroid which occurs in potatoes and other members of solanaceae family (e.g., aubergine) and the highly poisonous nightshades. Normally potatoes contain 2–15 mg per 100 g (fresh weight). When potatoes are exposed to light and turn green, the level of solanine can be as high as 100 mg per 100 g. It is mostly concentrated under the skin. Potato sprouts may contain even higher amounts. Solanine can cause abdominal pain and diarrhoea, if injested in large amounts. Solanine is an inhibitor of the enzyme acetyl choline esterase, which is a key component of the nervous system. Ingestion of solanine have been reported to lead to signs of neurological damage. As there is a general public awareness of the health hazards of eating green potatoes, the incidence of potato poisoning is low. Solanine is not lost during normal cooking as it is insoluble in water and is heat stable. Caffeine is a purine alkaloid. Theobromine is another important member of this group. These occur in tea, coffee, cocoa and cola beverages, which are regarded as stimulants.

  • Potential Terrorist Use of Nicotine and Solanine Toxins - 09/05/2003
    For Health Professionals Health Alerts Health Advisory #48 - Potential Terrorist Use of Nicotine and Solanine Toxins - 09/05/2003 Over the past several years, various reports have described a growing terrorist interest in the use of two plant toxins as potential mass poisoning agents. These kinds of poisons have been associated with training for limited-scope attacks, such as assassination. These poisons, nicotine and solanine, are naturally occurring toxins obtained from tobacco and potatoes, respectively. References to nicotine and solanine appear in numerous terrorist training manuals and documents seized in Afghanistan. There are no known instances of actual use of either poison by Islamic terrorist organizations; however, nicotine was used in a recent domestic criminal poisoning incident, resulting in the sickening of nearly 100 people in Michigan. The acute toxicity of nicotine is well documented as a result of a number of accidental poisonings. While comparatively less toxic than cyanide, botulinium toxin or ricin, both substances can be lethal in high doses or if medical treatment is significantly delayed. Both toxins occur naturally in established agricultural products making their availability and ease of chemical separation the key attractions for terrorists. The most likely technique for nicotine or solanine poisoning would be food, beverage, or water contamination; however, nicotine can also be absorbed through the skin and mouth and the digestive and respiratory tracts. Terrorist manuals detail simple instructions on how to produce both nicotine and solanine poisons. Nicotine is widely available, inexpensive, and uncomplicated--it can be produced using a basic knowledge of chemistry. Nicotine is a fast-acting poison, absorbed through the digestive and respiratory tracts, as well as through the skin and mouth.

Cooperstone1,2* 1 Department of Horticulture and Crop Science, The Ohio State University, Columbus, OH, United States, 2 Department of Food Science and Technology, The Ohio State University, Columbus, OH, United States Tomato steroidal glycoalkaloids (tSGAs) are a class of cholesterol-derived metabolites uniquely produced by the tomato clade. These compounds provide protection against biotic stress due to their fungicidal and insecticidal properties. Although commonly reported as being anti-nutritional, both in vitro as well as pre-clinical animal studies have indicated that some tSGAs may have a beneficial impact on human health. However, the paucity of quantitative extraction and analysis methods presents a major obstacle for determining the biological and nutritional functions of tSGAs. To address Edited by: this problem, we developed and validated the first comprehensive extraction and Heiko Rischer, VTT Technical Research Centre ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC- of Finland Ltd., Finland MS/MS) quantification method for tSGAs.

Navarre 3 1 School of Biological Sciences, Washington State University, Pullman, WA 99164, USA 2 Hermiston Agricultural Research and Extension Center, Department of Botany and Plant Pathology, Oregon State University, Hermiston, OR 97838, USA; [email protected] 3 USDA-ARS, Prosser, WA 99350, USA; [email protected] * Correspondence: [email protected] Abstract: With a growing world population, accelerating climate changes, and limited arable land, it is critical to focus on plant-based resources for sustainable food production. In addition, plants are a cornucopia for secondary metabolites, of which many have robust antioxidative capacities and are beneficial for human health. Potato is one of the major food crops worldwide, and is recognized by the United Nations as an excellent food source for an increasing world population. Potato tubers are rich in a plethora of antioxidants with an array of health-promoting effects. This review article provides a detailed overview about the biosynthesis, chemical and health-promoting properties of the most abundant antioxidants in potato tubers, including several vitamins, carotenoids and phenylpropanoids. The dietary contribution of diverse commercial and primitive cultivars are detailed and document that potato contributes much more than just complex carbohydrates to the diet. Finally, the review provides insights into the current and future potential of potato-based systems as tools and resources for healthy and sustainable food production.

Received: 27 March 2013; in revised form: 5 April 2013 / Accepted: 16 April 2013 / Published: 23 April 2013 Abstract: There is a need to develop food-compatible conditions to alter the structures of fungal, bacterial, and plant toxins, thus transforming toxins to nontoxic molecules. The term ‘chemical genetics’ has been used to describe this approach. This overview attempts to survey and consolidate the widely scattered literature on the inhibition by natural compounds and plant extracts of the biological (toxicological) activity of the following food-related toxins: aflatoxin B1, fumonisins, and ochratoxin A produced by fungi; cholera toxin produced by Vibrio cholerae bacteria; Shiga toxins produced by E. coli bacteria; staphylococcal enterotoxins produced by Staphylococcus aureus bacteria; ricin produced by seeds of the castor plant Ricinus communis; and the glycoalkaloid α-chaconine synthesized in potato tubers and leaves. The reduction of biological activity has been achieved by one or more of the following approaches: inhibition of the release of the toxin into the environment, especially food; an alteration of the structural integrity of the toxin molecules; changes in the optimum microenvironment, especially pH, for toxin activity; and protection against adverse effects of the toxins in cells, animals, and humans (chemoprevention).
