The Claim

US adults who consume tree nuts have a 22% prevalence of low high-density lipoprotein cholesterol and a mean HDL-C level of 58.6 mg/dL, compared to a 30% prevalence of low HDL-C and a mean HDL-C level of 53.3 mg/dL among nonconsumers, indicating a consistent association between tree nut intake and improved HDL-C profiles.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Adults in the US who eat tree nuts have lower rates of low HDL cholesterol and higher average HDL cholesterol levels than those who do not eat tree nuts.

See the scientific wording

US adults who consume tree nuts have a 22% prevalence of low high-density lipoprotein cholesterol compared to 30% among nonconsumers, and a 5.3 mg/dL higher mean HDL-C level (58.6 vs. 53.3 mg/dL), indicating a consistent association between tree nut intake and improved HDL-C profiles.

Why this might work

Eating tree nuts increases the liver's production of HDL cholesterol particles by boosting the release of a key protein called apoA-I, which gathers cholesterol from tissues and packages it into HDL particles that circulate in the blood.

    People who eat tree nuts regularly tend to have higher levels of 'good' cholesterol and are less likely to have low levels of it than those who don’t eat nuts — and this study with thousands of adults confirms that pattern.
