Lablokov, V, Sydora, BC, et al. Naturally Occurring Glycoalkaloids in Potatoes Aggravate Intestinal Inflammation in Two Mouse Models of Inflammatory Bowel Disease. Dig Dis Sci 55(11)3078-85.
This was a study done on mice. It demonstrated that consumption of potato skins containing glycoalkaloids can significantly aggravate intestinal inflammation in predisposed individuals.
Childers, N and Margoles, M. An Apparent Relation of Nightshades (Solanaceae) to Arthritis. Journal of Neurological and Orthopedic Medical Surgery 12(227-31.
This study describes the relationship between the consumption of nightshades and the development of arthritis. Blackpepper is exempted frm this list.
Tingey, W. Glycoalkaloids as Pest Resistance Factors. American Potato Journal 61(157)
This study showed the potato glycoalkaloids have antimicrobal and pesticidal properties to protect them from their natural enemies.
Patel, B, Schutte, R, et al. Potato Glycoalkaloids Adversely Affect Intestinal Permeability and Aggravate Inflammatory Bowel Disease. Inflamm Bowel Dis 8(5)340-6.
This study found that concentrations of glycoalkaloids normally available while eating potatoes can adversely affect the mammalian intestine and can aggravate inflammatory bowel disease
Nisha, P, Abdul Nazar, P, et al. A Comparative Study on Antioxidant Activities of Different Varieties of Solanum Melongena. Food Chem Toxicol 47(10)2640-4.
This study showed that extracts from purple colour small size eggplant fruit demonstrated better antioxidant activities than the other bigger samples. This my be attributed to the higher phenolic and anthocyanin content.
