Resumen
El texto original del estudio, en el idioma en que se publicó.
Objective
Previous interventions have reported desirable effects of diets rich in whole grains or rich in fruits and vegetables on cardiovascular disease (CVD) risk factors and weight management. However, data are lacking regarding the effect of these fiber sources separately. The aim of this randomized clinical feeding trial was to investigate the effects of fiber-rich diets with different sources of fiber (fruits, vegetables, and whole grains) on weight loss and CVD risk factors in overweight and obese women.
Methods
Overweight and obese women (N = 75) were randomized to one of three weight loss diets that were rich in whole grains, fruits and vegetables, or both for 10 weeks. Body weight, waist circumference, and risk factors of CVD were examined at baseline and 10 weeks.
Results
During the 10-week dietary intervention phase, the reductions in weight (p = 0.03), waist circumference (p = 0.001), systolic blood pressure (p = 0.04), fasting blood sugar (p = 0.03), and triglycerides (p = 0.001) were higher in the whole grains group compared with the fruits and vegetables group or the combination diet group. Also, the whole grain group had a greater increase (p = 0.01) in high-density lipoprotein cholesterol compared to the other groups. The change in other risk factors, including diastolic blood pressure and low-density lipoprotein cholesterol, was not different among the three diet groups. Within-group comparisons revealed significant reductions in weight, waist circumference, and fasting blood sugar in all groups. Only the fruits and vegetables group and the whole grains group had significant decreases in low-density lipoprotein cholesterol over 10 weeks (p ≤ 0.03).
Conclusions
This trial suggests that in overweight and obese women, a weight loss diet rich in whole grains may have a more beneficial effect on CVD risk factors than diets rich in fruits and vegetables or a combination of whole grains and fruits and vegetables.
