The Claim

Fructose-sweetened beverages increase postprandial and 24-hour plasma triglyceride levels and elevate small dense LDL cholesterol more than glucose-sweetened beverages in overweight adults over a 10-week period, independent of total caloric intake.

Cause and effect

In plain English

Drinking beverages sweetened with fructose raises plasma triglyceride levels and small dense LDL cholesterol more than beverages sweetened with glucose in overweight adults over 10 weeks, even when total calorie intake is held constant.

See the scientific wording

Fructose-sweetened beverages increase postprandial and 24-hour plasma triglyceride levels and elevate small dense LDL cholesterol more than glucose-sweetened beverages in overweight adults over 10 weeks, independent of total caloric intake.

Why this might work

When fructose is consumed, the liver processes it differently than glucose, producing more fat from scratch. This fat is packaged into large fat-carrying particles that flood the bloodstream. At the same time, the body’s ability to break down these particles slows down, so they stay in the blood longer. As these particles circulate, they change shape and become smaller, denser, and more harmful, raising the risk of artery damage.

What the research says

1 study
  1. Study: Dietary sugars: a fat difference.

    This study found that when overweight people drank drinks sweetened with fructose (like high-fructose corn syrup) for 10 weeks, their bodies made more harmful fats in the blood than when they drank drinks sweetened with regular sugar — even when they ate the same number of calories.
