Experts at the University of Toronto released their new findings in Obesity Reviews indicating that certain types of nutrition, like nuts, do not cause weight gain.
As part of their study, 121 clinical trials and prospective studies were examined, totaling more than 500,000 participants.
“Nuts are recommended for cardiovascular health, yet concerns remain that nuts may contribute to weight gain due to their high energy density,” the authors of the study wrote.
“A systematic review and meta-analysis of prospective cohorts and randomized controlled trials (RCTs) was conducted to update the evidence, provide a dose–response analysis, and assess differences in nut type, comparator and more in subgroup analyses.”
During their study, researchers searched through MEDLINE, Cochrane, and EMBASE.
The study concluded that no association existed between nuts and weight gain. Rather, researchers showed how higher intake may potentially reduce body weight.
“Meta-regression showed that higher nut intake was associated with reductions in body weight and body fat,” the authors explained in their results. “Current evidence demonstrates the concern that nut consumption contributes to increased adiposity appears unwarranted.”
