Abstract

The effect of instructing adults with cardiovascular disease on a lacto-ovovegetarian plus fish diet (15% total fat, <6% saturates, <100 mg cholesterol) or the standard diet (30% fat, 7-10% saturates, 200-300 mg cholesterol) was studied. Thirty-nine subjects were randomly assigned to the experimental or the control diet for 12 weeks. Measurements of weight, waist circumference, serum lipids and nutrition-related quality of life were taken before and after the intervention. Diets were monitored by 3-day food records and analyzed using the Nutritionist IV™ for Windows Version 4.1 diet analysis program. Adherence was self-reported by completion of a daily calendar. Statistical analyses were performed using SPSS 9.0 for Windows. The General Linear Model repeated measures procedure was used to compare the effects of the intervention on the two groups. Correlation analysis and multiple linear regression analysis were also conducted. There was no difference between the two groups in actual diet followed during the intervention (17.4% total fat, 4.4% saturated fat, 135 mg cholesterol per day) nor in outcome measures. Both groups benefited equally from diet intervention. Weight decreased by 2.1% (p
