There is their problem. While the off-diet consequences are the same for men and women, no one else is affected by a man's off-diet symptom. At 17, I did research it further and I was told by several people that while treating the diet may be possible on a base, if a person were to be deployed to war or some major conflict, the can only eat what they are given. They are not given choices many times. Also, food and formula cannot be delivered to some of these feild places. I understand that much of the military is not battle, so though I don't know how, there must be some way for someone with PKU to join if they do not get deployed to field work.
