The Claim
Between 1990 and 2023, the global age-standardized death rate from ischemic heart disease attributable to suboptimal diet decreased by 43.92%.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
From 1990 to 2023, the number of deaths from heart disease caused by poor diet fell by 43.92% worldwide when adjusted for population age differences.
See the scientific wording
The global age-standardized death rate from ischemic heart disease attributable to suboptimal diet decreased by 43.92% between 1990 and 2023, indicating a significant reduction in diet-related cardiovascular burden over three decades.
People eat more fruits, vegetables, whole grains, and nuts, and less salt, sugar, and unhealthy fats. This lowers bad cholesterol and blood pressure, which stops fatty buildup in artery walls and prevents those plaques from cracking and blocking blood flow to the heart.
What the research says
1 studyThe study found that over the last 30 years, the number of heart disease deaths caused by bad diets dropped by about 44% worldwide — which matches the claim exactly. This means fewer people are dying from heart disease because of poor eating habits now than in the 1990s.
