Thanks. I forgot to mention initially that when I was young (maybe 2 years old) I had a lot of digestive problems. Apparently the pediatrician diagnosed it as celiac (I am not sure if just by clinical observation or blood test - it was around 1960!). Unfortunately my parents are deceased and I can not locate that doctor - he is probably deceased as well. I recovered from that period however and have not had any real digestive issues since.
