Colorectal cancer is the second most common form of cancer death in Western countries. Diet has been implicated in the aetiology of this disease. Epidemiological evidence suggests that diets high in meat and fat and low in fermentable carbohydrate increase colorectal cancer risk. One mechanism that could explain the association with meat is increased(More)
BACKGROUND Sulfiting agents are widely used as food additives. Limits are set on their use in foods because they may adversely affect health. Sulfiting agents are excreted in urine as sulfate, which is indistinguishable from sulfate derived from sulfur amino acids. OBJECTIVE The objective was to assess the contribution of inorganic sulfur to urinary(More)
Hydrogen sulphide is produced in the human large intestine by the bacterial reduction of dietary inorganic sulphate and sulphite and by fermentation of sulphur amino acids. Sulphide may damage the colonic epithelium and has been implicated in the pathogenesis of ulcerative colitis. The accurate measurement of sulphide in biological samples, particularly in(More)
BACKGROUND Hydrogen sulfide is a luminally acting, bacterially derived cell poison that has been implicated in ulcerative colitis. Sulfide generation in the colon is probably driven by dietary components such as sulfur-containing amino acids (SAAs) and inorganic sulfur (eg, sulfite). OBJECTIVE We assessed the contribution of SAAs from meat to sulfide(More)
Thirty-one men (47 (SD 14) years) and thirty-four women (35 (SD 13) years) took part in a 4-week randomized cross-over trial to compare the effect of six mugs of black tea daily v. placebo (water, caffeine, milk and sugar) on blood lipids, bowel habit and blood pressure, measured during a run-in period and at the end of weeks 2, 3 and 4 of the test periods.(More)
BACKGROUND The relapsing nature and varying geographical prevalence of ulcerative colitis (UC) implicates environmental factors such as diet in its aetiology. METHODS In order to determine which foods might be related to disease activity in UC a new method of dietary analysis was developed and applied. Eighty-one UC patients were recruited at all stages(More)
A semi-structured, web-based questionnaire was developed to survey midwives (n = 241) employed by NHS Tayside, UK, to identify current practice and views on weight management of obese women during pregnancy and the puerperium. A total of 78 (32%) midwives submitted responses following email invitation. Most respondents (79%) reported always calculating(More)
The toxic, bacterial metabolite sulfide is implicated in ulcerative colitis. Ulcerative colitis patients taking 5-aminosalicylic acid-containing drugs have lower fecal sulfide levels than those not taking these drugs. The effects of sulfasalazine, balsalazide, olsalazine, and 5-aminosalicylic acid on sulfide production were studied in a three-stage(More)
