47: Nickel Allergy & IBS: The Connection You Need to Know

·44 min·2 clips

Everything tested negative until one weird detail unlocked the whole puzzle in 72 hours.

Gut Fit Nutrition Episode 47 features registered dietitian Tamara Duker-Fruman discussing systemic nickel allergy syndrome (SNAS) as overlooked cause of IBS symptoms. Through case studies including a celiac patient reacting to nickel-rich foods and a patient misdiagnosed for years, Tamara explains the mechanism (contact mucositis in GI tract), prevalence (5% of those with nickel dermatitis), and diagnostic/management pathways. Discussion emphasizes how elimination diet culture creates fear around food and highlights complexity of food chemical sensitivities beyond FODMAP.
