Agreed: eggs are major allergens. Perhaps the reason eggs cause so much difficulty with IBS, gas, bloating etc. is related to this fact: put one in the microwave and IT EXPLODES!!! So, it follows that an egg would explode in your pants, your gut, the human body. Also, eggs contain a lot of SULFUR--the stuff that's in garlic, onions, cabbage and cruciferous veggies that people with IBS tend to be hyper-sensitive too. Fat is another issue/trigger.
