Cardiovascular diseases (CVD), such as stroke, myocardial infarction and atherosclerosis are a major cause of morbidity and mortality throughout the western world. This cross-sectional study was conducted to investigate the relationship between dietary saturated fat intake and developing risk factors associated with the aetiology and pathogenesis of CVD. Volunteers (13 men and 12 women) were recruited from students of Cardiff Metropolitan University. Dietary intake through a 7-day food diary was analysed through Nutrimen, and body composition, resting heart rate, blood pressure, and body mass index were assessed in relation to dietary saturated fat intake. Measures variables and their relationships were assessed by 2-sample T tests, and by linear regression analysis. Dietary saturated fat was positively associated with systolic (p >0.05) and diastolic (p = <0.05) blood pressure and body fat percentage (p >0.05) and negatively associated with heart rate (p >0.05) in males. Body fat percentage was positively associated with diastolic blood pressure (<0.05) in males, but not in females (>0.05). There was almost no association between diastolic blood pressure (p >0.05) and saturated fat in females, and a negative association between saturated fat and heart rate (p >0.05). The data of this study indicated gender-related differences in response to dietary saturated fat and body composition. Although the men who took part in the study were all relatively diet and exercise conscious, their body fat percentage and diastolic blood pressure readings are indicative of a risk of cardiovascular disease. More dietary recommendations and education should be provided surrounding replacement of dietary saturated fat, but customary dietary and lifestyle advice may be required for men in comparison to women who appeared unaffected in the study.
