In the article discussing nightshade vegetables and their impact, Scott Keatley, RD, from Keatley Medical Nutrition Therapy, offers his expertise by explaining the two types of nightshades—edible and toxic. He clarifies that while toxic nightshades are naturally avoided as they are not available in supermarkets, edible nightshades like peppers, eggplants, tomatoes, and potatoes are common in diets but can be controversial due to their alkaloid content. Keatley further delves into the specifics of glycoalkaloids, a group of chemicals found in nightshades that can potentially cause inflammation depending on individual sensitivity. His contribution is crucial in providing a balanced view on the potential risks and benefits of consuming nightshades, particularly for individuals with sensitivities or autoimmune conditions.
