What are nightshades? As a botanical family, the Solanaceae comprise some ninety-two genera with over two thousand species. Its members include many stimulating, medicinal, or poisonous plants, such as tobacco, henbane, mandrake, and belladonna (also known as the deadly nightshade). The food plants of the nightshade family include some of our most popular vegetables: tomatoes, potatoes, eggplant, and peppers of all kinds (green, red, chili, paprika, cayenne, hot and sweet, except for black and white pepper.)
Research has found that when people with joint pains stopped consuming all varieties of nightshades, their condition improved dramatically.
It turns out that nightshades are high in alkaloids, chemical substances with a strong physiological effects. In the case of potatoes, storage conditions after harvest that include light and heat, may over time increase the content of the alkaloid solanine to toxic limits. Improperly stored old potatoes have been know to cause symptoms severe enough to require hospitalization, including gastrointestinal inflammation, nausea, diarrhea, and dizziness.
Earl Mindell in his book, Unsafe at Any Meal, stated the following concerning potatoes, "Solanine, present in and around these green patches and in the eyes that have sprouted, can interfere with the transmission of nerve impulses, and cause jaundice, abdominal pain, vomiting, and diarrhea."
These alkaloids act a little like a variation of Vitamin D, in that they appear to affect the metabolism of calcium. Nightshade foods may, through a mechanism not yet understood, remove calcium from the bones and deposit it in joints, kidneys, arteries, and other areas of the body where it does not belong. Thus, they may contribute to arthritis.
Nightshades are consumed in appreciable quantities mostly in dietary systems that also include milk products. These foods often show up in pairs: tomato sauce and cheese, potatoes and sour cream, spicy Indian foods, yogurt, and eggplant parmigiana.
Nightshades, with their calcium-disturbing alkaloids, have something to do with the digestion or assimilation of milk products, which have an excessively high calcium content. Cow's milk contains four times more calcium than human mother's milk, and that may turn out to be too much for the human metabolism to handle.
In other words, when the nightshades are consumed in calcium-rich diets, they help keep the calcium from depositing in the wrong places, as long as the body is functioning properly. If it is not, then either the nightshades pull out calcium from the wrong places or the dairy calcium is improperly used by the body and collects in the joints and tissues. Symptoms of improper storage include bone loss, tooth decay, and what is called the "naked tooth feeling" (a sensation of rawness or brittleness in the teeth). If you are avoiding dairy foods and eating a low fat diet, you may want to eliminate the nightshade vegetables from your diet.
Dr. Collin H. Dong, a San Francisco Physician created a diet called the "Dong Diet." He believes arthritis is caused by allergic reactions to certain food and chemical additives in the food. His diet prohibits meat, fruits, tomatoes, all dairy products, all acids including vinegar, all types of peppers, hot spices, chocolate, roasted nuts, alcoholic beverages, especially wine, soft drinks, all foods containing preservatives, additives and chemicals, especially MSG (monosodium glutamate).
His diet favors fish, because fish oils appear to benefit arthritis. This diet cuts back on most of the nightshades, eggs, vitamin A and D, in supplement form, and foods fortified with these vitamins, such as margarine. The sun on the skin promotes sufficient vitamin D, the green leafy vegetables, the orange colored ones, such as carrots, sweet potatoes, and cantaloupes provide plenty of vitamin A in the diet. Norman F. Childers, a former Professor of Horticulture, Rutgers University had severe joint pains and stiffness after consuming tomatoes in any form. He was aware of the nightshade family of plants and their toxicity. He observed livestock kneeling because their knee joints were too painful to hold them up, after eating weeds containing solanine. He then started to test the nightshade foods one at a time and found that each one aggravated his arthritic pain. He eliminated all of the nightshade vegetables from his diet and within months his pain vanished. He totally believes that those who are sensitive or allergic to the nightshade vegetables will cure the aches and pains of arthritis by avoiding those foods.
The macrobiotic diet, noted for its healing properties, forbids meat, eggs, dairy products, poultry, fruit juices, and nightshade vegetables. If one has arthritis, bone loss, or aching muscles and joints, the nightshade vegetables should be omitted from their diet to see if their condition improves.
