The Claim

Excess fructose consumption disrupts intestinal barrier function, which promotes endotoxemia and systemic inflammation through activation of gut microbiota and Toll-like receptor 4 signaling, thereby contributing to the development of atherosclerosis.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Eating too much fructose, like the sugar in soda and candy, can damage the lining of your gut, letting harmful toxins leak into your bloodstream, which triggers body-wide inflammation and may lead to clogged arteries.

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

    This study says too much sugar, especially fructose, can cause inflammation and heart disease, which matches the claim that fructose harms the gut and leads to heart problems through inflammation.
