The Study
John Yudkin’s hypothesis: sugar is a major dietary culprit in the development of cardiovascular disease
This paper is like a storybook that collects other people’s observations about sugar and heart disease — it says 'many studies think sugar might be bad,' but it didn’t do any experiments itself, so we can’t say sugar definitely causes heart problems.

Eating too much fructose, like the sugar in soda and candy, can mess up your liver’s ability to respond to insulin, make more fat in your liver, and raise fat levels in your blood, which can lead to bigger health problems like heart disease.
Eating too much fructose, like the sugar in soda and sweet snacks, makes your liver create more fat, which raises bad fats in your blood and causes body-wide inflammation, making heart disease more likely.
Eating too much fructose over a long time can mess up how your liver responds to insulin, making your body produce more insulin, cause body-wide inflammation, and raise fat levels in your blood—all of which raise your risk of heart disease.
Even though people are eating less cholesterol, more people are dying from heart disease — so maybe sugar, especially fructose, is to blame instead.
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.
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.
