The Claim

Excess dietary fructose consumption is associated with elevated uric acid levels, which contribute to endothelial dysfunction and hypertension through oxidative stress and reduced nitric oxide production, thereby increasing the risk for atherosclerosis.

How it works

In plain English

Eating too much fructose, like the sugar in soda and candy, can raise a substance in your blood called uric acid, which may damage your blood vessels and raise your blood pressure, making heart disease more likely.

  1. Study: John Yudkin’s hypothesis: sugar is a major dietary culprit in the development of cardiovascular disease

    This study says that eating too much sugar, especially fructose, can raise uric acid in the blood, which harms blood vessels and raises blood pressure — making heart disease more likely. It agrees with the claim that fructose is a key culprit.
