There is still some basic agreement. There NIH came out with guidelines which eliminate a lot of possible arguments.
I think there is a basic level of info doctors should give but many do not know to give such as that the epis should always be carried, the person should always be with someone who knows the signs of ana, the emergency plan and how to use the epi pen. The person should receive a clear, written, emergency plan at least somewhat similar to the plans put out by FAAN, FAIII (sp?), Dr. Wood, etc. Avoid may contains already is mainstream advice recommended by all food allergy organizations, etc. The fact that some allergists do not recommend it doesn't change this. There are some exceptions such as my son who can eat some forms of milk and can now eat some things that say, 'may contain milk' but this is *general* advice. Avoid bakery food if allergic to milk, eggs, nuts. Avoid Asian food with a peanut, nut, sesame allergy, etc etc. Read every ingredient label every time. Call companies if have non-top 8 or if want to be sure no x-contam since x-contam labeling is voluntary. The need for and how to be careful at restaurants., etc. Past reactions do not determine future ones and reactions can change. Hives upon ingestion = possible future anaphylaxis and reason to carry epi.
People shouldn't be dying because they didn't know Chinese food was risky with a peanut allergy, that their past reactions when they 'just got hives and some minor breathing trouble' meant they should have and use epi pens, because they waited to long to epi, because they thought epi was dangerous, because they didn't know bakery cakes had risk, etc, etc.
I think there already is a pretty set standard of info that if we look at FAAN's website and books sold there and those at kids w FAS and FAIIII (sp?), Ana Canada, etc, will all agree upon 98% of the time. So, saying there isn't full agreement is not really true. There isn't ever going to be full agreement but there are basic recommendations that aren't making it to pediatricians and ENTs and GI docs and even some allergists and are not making it to all parents of food allergic kids and adults with FAs. Most people at kids w fas have stories of it taking multiple doctors before getting a proper diagnosis and correct info. I went through 3 doctors including one allergist before the 4th doctor finally gave us the correct diagnosis. I was working hard, reading, asking all the right questions, researching, and got bad and incorrect info from those 3 doctors and many books, etc. It wasn't for my lack of effort.
