But no I don't think the UK advanced, avoid avoid anything in a packet, tins less so bad or not at all. Ask a regular medic about diet, and when he poo-poos the idea ask him how much nutritional time didi he experience at med school. I think the response would be circa two hours give or take, 15 hours would not be enough, which makes my comment of the packet in diet sound flippant. In a nutshell , in a sentence as far as diet is concerned you won't get better advice, although I am willing to listen to better ideas.
As for flight and fight state it is in my opinion the worst thing that activates illness. Without it I wouldn't have a job, as regardless of the presenting complaint without stress/tension/diet I feel it it would not come to light, hence not enough people in the door to make a living. Unlike years ago, running from Sabir tooth lion etc, we can't run we have other responsibilities,or we face the same tiger in our jobs or work which are there tomorrow, and hence we experience the same initial physiological response as we would years ago but with no outlet, and hence hormonal metabolic dysruption and its consequences. If one is experiencing stress, treatment of any kind may empty part of the glass temporarily until you refill as modern constraints mean it is harder to run, and the stress is still there. Work. money and spouse/ relationships are potentially the main source of stress, and with it its main restraints/ anchor, and a precipitating/ maintaining factor of diet. Not saying I'm right but without it I believe I wouldn't have a job. (physical therapist)
