I should clarify - there are various versions you can do of the RPAH elimination diet
1. Strict
2. Moderate
3. Simple
"Failsafe" refers to the strict version where one only eats for the "low" foods. in the moderate version, one eats lows and omderate chemical foods, and in the simple approach only the "very highs" are excluded but all other foods are eaten. On all, 1,2&3 no preservatvies or additives are eaten. It is up to you on which allergins you exclude out fo dairy/soy/egg/wheat/nut/fish. For those who are breastfeeding babies that have reflux and colic. mucuus poos, rash bottoms and unsettled the standard advice it to exlcude all allergins but eat at the moderate level for the natural food chemicals (amines, glutamates and salicylates) .
The reason for moderate is that the alot can get away with this and it is exponentially easier to last on the diet if you can have the range of foods in the moderate category. For the hungry breastfeeding moether the low approach is very very hard. I felt it important to eat fresh salmon (moderate sals) for the good fats, as the only other fats are coming from rice bran oil, canloa oil and sunflower oil and animal fats from meat. Having said all that I had to limit my mderate to one serve of moderate every 2 days for a little while just to get him to symptom free, then go back to one serve every day. A few months later I was on unrestricted moderate.
I used Karicare Food thickener available in Australia. If you are in the US the one to use is simply thick however check that it doesn't have preservatives in it
