The Study
Red Meat Consumption and Risk of Cardio-Cerebrovascular Disease in Chinese Older Adults.
This study watched what people ate and then saw who got sick over time. It found that people who ate more red meat sometimes had more heart problems — but only in some groups, like city folks with more money. It didn't prove that red meat made them sick, just that the two things often happened together.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
In China, older people who eat more red meat sometimes get more heart problems — but sometimes live longer. It depends on where they live and how much money they have.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — for poor or rural elderly, red meat may be a vital source of protein that saves lives, while for wealthier urban elderly, excess meat may contribute to heart disease.
- 2For every extra 50g of red meat a day: urban rich people had 12% higher stroke risk, but rural poor people had 16% lower stroke risk and 20% lower death risk.
