It costs $100 a month for her medication ( when she is well!) So I was interested to stumble across these reports today:- 1. Evidence for opioid modulation and generation of prostaglandins in sulphur dioxide (SO)2-induced bronchoconstriction.[My paper] P I Field, R Simmul, S C Bell, D H Allen, N BerendDepartment of Thoracic Medicine, Royal North Shore Hospital, New South Wales, Australia.BACKGROUND: Inhalation of sulphur dioxide (SO2) provokes bronchoconstriction in asthmatic subjects. Cholinergic mechanisms contribute, but other mechanisms remain undefined.

Purpose• The main purpose of the survey was to establish whether soakingchipped potatoes in a sulphite solution is common practice in fish andchip shops in the Falkirk Council Area. Due to rising obesity and heartdisease in the UK it was also decided that fat and salt levels should beanalysed.2. Background• A food complaint sample of potato fritters investigated at the Aberdeenpublic analyst laboratory was found to have very high levels of sulphurdioxide in the product. The investigation established that chippedpotatoes used by the chip shop were soaked in a solution of ‘Drywite’,which contained sulphur dioxide. It was established that there wasminimal control over the concentration of solution used by the FoodBusiness Operator.• Additives such as Sulphur dioxide or sulphites affect up to 40% ofchildren with asthma, they are commonly ingested in dried fruit, softdrinks and sprayed onto fresh produce. It is the Sulphur dioxide gas,which is eructed from the stomach that results in throat irritation andwheezing. Allergic individuals also seem to have low levels of sulphiteoxidase, the enzyme that normally metabolises sulphites in the diethttp://www.falkirk.gov.uk/services/development/food_and_safety_regulation/food_safety/food_safety_tips/chip_shop_survey.pdfAnyone with any thoughts, experiences, comments?tarm Quote Link to comment Share on other sites More sharing options...
