The Claim

Suboptimal diet is associated with 4.06 million ischemic heart disease deaths and 96.84 million disability-adjusted life years globally in 2023 across 204 countries.

Source: Global, regional and national burden of ischemic heart disease attributable to suboptimal diet, 1990-2023: a Global Burden of Disease study.

See the scientific wording

Suboptimal diet is associated with 4.06 million ischemic heart disease deaths and 96.84 million disability-adjusted life years globally in 2023, representing a major modifiable contributor to cardiovascular burden across 204 countries.

Why this might work

Eating too much unhealthy food raises bad cholesterol and lowers good cholesterol, causing fatty deposits to build up in heart arteries. These deposits harden and narrow the arteries, blocking blood flow to the heart muscle. When the blockage is severe, the heart muscle doesn't get enough oxygen and dies, causing a heart attack.

  1. Study: Global, regional and national burden of ischemic heart disease attributable to suboptimal diet, 1990-2023: a Global Burden of Disease study.

    This study found that bad eating habits caused about 4 million heart disease deaths and 97 million years of poor health worldwide in 2023 — exactly what the claim says. So yes, poor diet is one of the biggest preventable causes of heart disease.
