The Claim

In U.S. adults, consuming at least 7.09 grams of tree nuts per day is associated with a 9 percentage point lower prevalence of obesity and a 1.42 cm lower waist circumference compared to nonconsumers, after adjustment for age, income, education, physical activity, and smoking status.

In plain English

U.S. adults who eat at least 7.09 grams of tree nuts daily have a 9 percentage point lower rate of obesity and 1.42 cm smaller waist circumference than those who do not eat tree nuts, even when accounting for age, income, education, physical activity, and smoking.

See the scientific wording

In U.S. adults, consuming at least 7.09 grams of tree nuts per day is associated with a 9 percentage point lower prevalence of obesity (31% vs. 40%) and a 1.42 cm lower waist circumference compared to nonconsumers, even after adjusting for age, income, education, physical activity, and smoking status, suggesting a consistent link between modest tree nut intake and reduced central adiposity.

Why this might work

Eating tree nuts makes you feel full faster and for longer, so you eat less overall. The nuts also make your body absorb fewer calories from food, and the fat in them gets stored less in the belly. This leads to a smaller waist and less body fat.

    People in the U.S. who eat at least a quarter-ounce of tree nuts every day tend to have smaller waistlines and are less likely to be obese than those who don’t, even when you account for differences in how much they exercise, their income, or whether they smoke.
