In this episode of Rooted and Restless, Marianne Smith Edge sits down with Dr. Heather Norman-Bergdolf, assistant extension nutrition professor at the University of Kentucky, to unpack the growing reality of alpha-gal syndrome—a food allergy linked to Lone Star tick bites.

As cases rise across Kentucky and much of the Midwest and Eastern U.S., they unpack the science behind this unusual condition, why symptoms can appear hours after eating red meat and other mammal-based foods, and the everyday challenges of navigating food labels and outdoor life.

What We Cover:

• How alpha-gal syndrome develops after tick bites

• Why reactions to red meat and dairy are often delayed

• Hidden mammal-derived ingredients in foods and products

• Cross-contamination and food preparation challenges

• Tick prevention and outdoor safety tips

• New research and the possibility of reintroducing foods over time

Alpha-gal syndrome may change what’s on the plate, but with awareness, prevention, and support, flavorful food and active outdoor lifestyles can still be enjoyed.
