The Claim

In female rats, glucose supplementation increases plasma adiponectin levels and hepatic PPARα expression, which is associated with increased endothelial nitric oxide synthase (eNOS) phosphorylation and improved aortic relaxation in response to nitric oxide donors, despite higher caloric intake compared to fructose.

Source: Type of supplemented simple sugar, not merely calorie intake, determines adverse effects on metabolism and aortic function in female rats.

How it works
1 study reviewed
In plain English

In female rats, glucose supplementation raises levels of adiponectin and PPARα in the liver, which correlates with increased phosphorylation of eNOS and greater relaxation of the aorta when exposed to nitric oxide donors, even though glucose provides more calories than fructose.

See the scientific wording

In female rats, glucose supplementation increases plasma adiponectin and hepatic PPARα expression, which is associated with enhanced endothelial nitric oxide synthase (eNOS) phosphorylation and improved aortic relaxation to nitric oxide donors, despite higher caloric intake than fructose.

Why this might work

When glucose is consumed, fat tissue releases more of a hormone called adiponectin. This hormone signals the liver to make more of a protein called PPARα, which in turn helps blood vessels produce more nitric oxide by activating an enzyme called eNOS. More nitric oxide makes blood vessels relax more easily, improving blood flow, even when more calories are eaten compared to fructose.

  1. Study: Type of supplemented simple sugar, not merely calorie intake, determines adverse effects on metabolism and aortic function in female rats.

    In female rats, giving them glucose made their blood vessels relax better by boosting a helpful hormone and a key protein, even though they ate more calories than rats given fructose. Fructose did the opposite—it hurt blood vessel function.
