The Claim

In U.S. adults, tree nut consumption is associated with a 22% prevalence of low high-density lipoprotein cholesterol compared to 30% in nonconsumers and a 5.3 mg/dL higher mean HDL-C level (58.6 vs. 53.3 mg/dL).

In plain English

U.S. adults who eat tree nuts have a lower rate of low HDL cholesterol and higher average HDL cholesterol levels than those who do not eat tree nuts.

See the scientific wording

In U.S. adults, tree nut consumption is associated with a 22% prevalence of low high-density lipoprotein cholesterol compared to 30% in nonconsumers, and a 5.3 mg/dL higher mean HDL-C level (58.6 vs. 53.3 mg/dL), suggesting a consistent link between tree nut intake and improved HDL-C profiles.

Why this might work

Eating tree nuts increases the liver's production of good cholesterol particles by boosting the creation of a key protein that holds them together, which raises the amount of good cholesterol in the blood.

    People who eat tree nuts like almonds or walnuts tend to have higher levels of good cholesterol than those who don’t, and this study found that difference in a large group of U.S. adults — even after accounting for other healthy habits.
