Background:Regular consumption of nuts and peanuts may reduce the risk of cardiovascular disease due to the bioactive compounds found within them. Previous research suggests that including nuts and seeds as part of an overall healthy dietary pattern may help manage blood pressure, cholesterol, triglyceride, and fasting blood glucose levels, but few studies have examined the specific effect of dry-roasted, skinless peanuts on these outcomes.
Objective:The objective was to examine the effect of regular consumption of dry-roasted, skinless peanuts on markers of metabolic health among women.
Methods:This was a pre-post test study. Eligible women were randomized into either the intervention group (49 g peanuts/day, n=30) or the control group (participants’ usual diet minus peanuts, n=28) for 12 weeks. Anthropometrics, cholesterol, triglyceride, fasting blood glucose, and blood pressure levels were measured at baseline and end-line.
Results:There were no significant between-group differences for any of the outcomes of interest. For the peanut group, there was a significant within-group decrease in systolic blood pressure (-7.0 mmHg; 95% CI: 1.3, 12.6), and a significant increase in total: HDL cholesterol ratio from baseline to endline (0.2; 95% CI: -0.3, 0.02). There was a significant within-group decrease in diastolic blood pressure for the control group (-6.3 mmHg; 95% CI: 2.0, 10.6).
Conclusion:Among healthy young women, the addition of daily peanuts to a usual diet does not appear to negatively affect body composition as measured by BMI, waist circumference, and body fat percentage. Further research is needed to fully elucidate the effect of peanut consumption on indicators of cardiovascular health in different populations.
