The Claim

Higher fructose intake in adolescents is associated with reduced plasma HDL-cholesterol levels, independent of total fat mass, physical activity, and dietary fiber intake.

Source: Greater fructose consumption is associated with cardiometabolic risk markers and visceral adiposity in adolescents.

What the research says

Supports is higher

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

In plain English

Adolescents who consume more fructose have lower levels of HDL-cholesterol in their blood, even when accounting for their body fat, physical activity, and fiber intake.

See the scientific wording

Higher fructose intake in adolescents is associated with reduced plasma HDL-cholesterol, a key marker of cardiovascular risk, independent of total fat mass, physical activity, and dietary fiber intake.

Why this might work

When adolescents consume a lot of fructose, the liver converts it into fat more aggressively than other sugars. This fat builds up around internal organs, which triggers inflammation and disrupts insulin signaling. The inflamed fat tissue and insulin resistance reduce the production of good cholesterol and increase the release of bad cholesterol particles, lowering the amount of good cholesterol in the blood.

    Teens who eat more fructose tend to have lower levels of 'good' cholesterol, even if they’re not overweight or inactive — but this might be partly because fructose causes fat to build up around their organs, which also lowers good cholesterol.
