Taste and Memory

I have a question about the episode "Escaping Diet and Wellness Culture in Fashion and Dietetics with Shana Minei Spence" and the segment on Allergy Awareness. You mentioned on the Sean Ryan podcast that you do not develop allergies to shellfish in your 30s, meaning that later in life these allergies do not develop. However, I have developed allergies in my 40s, and although most of the issues could be related to leaky gut, which you discussed later on the podcast, shellfish affected me differently. Just peeling the shrimp caused my lips to swell up. Long story short, I'm interested in your thoughts and opinions on possible alternatives to my current treatments and situations regarding shellfish allergies. Thank you in advance for your time.
