BACKGROUND Vegetarians have lower platelet and plasma concentrations of n-3 polyunsaturated fatty acids (PUFAs) than do omnivores. We recently showed that male vegetarians have higher platelet aggregability than do omnivores. OBJECTIVE We investigated whether male vegetarians (n = 17) who consumed an increased amount of dietary alpha-linolenic acid (ALA)(More)
OBJECTIVE To determine whether healthy males who consumed increased amounts of dietary stearic acid compared with increased dietary palmitic acid exhibited any changes in their platelet aggregability, platelet fatty acid profiles, platelet morphology, or haemostatic factors. DESIGN A randomized cross-over dietary intervention. SUBJECTS AND INTERVENTIONS(More)
OBJECTIVE To determine the effect of habitual omnivorous and vegetarian diets on folate and vitamin B12 status and the subsequent effect on homocysteine concentration. DESIGN Cross-sectional comparison of free-living habitual meat-eaters and habitual vegetarians. SETTING The study was conducted at RMIT University, Melbourne. SUBJECTS One hundred and(More)
OBJECTIVE The aim of this study was to assess thrombosis tendency in subjects who were habitual meat-eaters compared with those who were habitual vegetarians. DESIGN Cross-sectional comparison of habitual meat-eaters and habitual vegetarians. SETTING Free living subjects. SUBJECTS One hundred and thirty-nine healthy male subjects (vegans n = 18,(More)
OBJECTIVE To determine whether healthy males who consumed increased amounts of dietary stearic acid compared with increased dietary palmitic acid through the consumption of commercially available foods, exhibited any changes in plasma lipids, platelet aggregation or platelet activation status. DESIGN A randomised cross-over dietary intervention. (More)
Stearic acid is a saturated fatty acid found in meat fat and chocolate. Studies from more than 30 yr ago indicated that stearic acid might promote blood clotting through increased platelet aggregation (1). More recent studies have indicated that stearic acid is unique as a saturated fatty acid in that it does not cause an increase in blood cholesterol(More)
