Even their advice on the NSD is dreadful - 'No restriction on beverages'. Beer and Guiness (grain based) caused my hips to flare for weeks. I just have to live with wine and chocolate for my treats instead
"NO RESTRICTIONS ON BEVERAGES OR SPICES (Pepper, salt or herbs)"
Although you may feel that you have problems with drinking beer/Guiness, that was apparently not Dr Ebringer's advice in the "London AS Diet". NASS, like the SAA, has been pretty careful to take a neutral position on the diet - as is appropriate for an as yet unproven (though not apparently harmful) theory.
