The Study
Nut Consumption and Weight Gain in a Mediterranean Cohort: The SUN Study
This study watched a big group of people over time to see if eating nuts was linked to gaining less weight. It found that people who ate nuts more often were less likely to gain 5 kg or more, but it can't prove that nuts caused the difference.
