Methods
In this article, researchers looked at the relationship between nut consumption and long-term weight change over 20-24 years. A total of 144,885 individuals were used in the analysis from 3 separate studies that included both men and women.
Key Findings
Key Findings: The average weight gain across individuals in the study was 0.32 kg per year (0.7 lbs). However, eating atleast a 1/2 serving of nuts (including peanuts) each day was associated with less weight gain per 4-year interval. Specifically, peanut consumption was associated with 0.15 kg less weight gain. The authors conclude that eating nuts/peanuts is associated with lower risk of obesity in adults, and that including them in the diet instead of less healthful foods may be a simple strategy to prevent obesity and weight gain over time.
