OBJECTIVE To investigate dietary determinants of ischaemic heart disease (IHD) in health conscious individuals to explain the reduced risk in vegetarians, and to examine the relation between IHD and body mass index (BMI) within the normal range. DESIGN Prospective observation of vegetarians, semi-vegetarians, and meat eaters for whom baseline dietary(More)
AIMS/HYPOTHESIS A diet low in saturated fatty acids and rich in wholegrains, vegetables and fruit is recommended in order to reduce the risk of obesity, cardiovascular disease and type 2 diabetes mellitus. However there is widespread interest in high-fat ("Atkins Diet") and high-protein ("Zone Diet") alternatives to the conventional high-carbohydrate,(More)
To assess the effect of dietary reduction of plasma cholesterol concentrations on coronary atherosclerosis, we set up a randomised, controlled, end-point-blinded trial based on quantitative image analysis of coronary angiograms in patients with angina or past myocardial infarction. Another intervention group received diet and cholestyramine, to determine(More)
BACKGROUND The results of observational studies suggest that plasma homocysteine concentrations are inversely related to cognitive function in older people. Our objective was to test the hypothesis that lowering the plasma homocysteine concentration improves cognitive function in healthy older people. METHODS We conducted a two-year, double-blind,(More)
In a randomised cross-over study 18 nondependent (NIDDM) and 9 insulin-dependent (IDDM) diabetics were put on to a high carbohydrate diet containing leguminous fibre (HL) for 6 weeks, and also a standard low carbohydrate diet (LC) for 6 weeks. During two identical 24 h metabolic profiles mean preprandial and mean 2 hour postprandial blood glucoses were(More)
The Diabetes and Nutrition Study Group (DNSG) of the European Association for the Study of Diabetes (EASD) has issued a series of updated statements regarding the nutritional management of patients with diabetes (1-3). These have been based on the best available evidence derived from the scientific literature and the collective clinical experience of(More)
OBJECTIVE The extent to which lifestyle must be altered to improve insulin sensitivity has not been established. This study compares the effect on insulin sensitivity of current dietary and exercise recommendations with a more intensive intervention in normoglycemic insulin-resistant individuals. RESEARCH DESIGN AND METHODS Seventy-nine normoglycemic(More)

SETTING Free-living community subjects. SUBJECTS Fifty vegetarians were recruited by local advertisement. Each vegetarian selected their own(More)
BACKGROUND Elevated plasma total homocysteine (tHcy) concentrations are associated with increased risk of vascular disease, and there is a strong inverse association between dietary and blood folate and blood tHcy concentrations. Increased folate consumption may lower the risk of tHcy-mediated cardiovascular disease. OBJECTIVES The objective was to(More)
