In plain English

In Chinese adults aged 65 and older, eating 50 more grams of red meat each day is linked to a 10% higher risk of heart and brain blood vessel disease in high-income urban areas, but not in low-income or rural areas.

See the scientific wording

Among Chinese adults aged 65 and older, an additional 50 grams of daily red meat consumption is associated with a 10% higher risk of cardio-cerebrovascular disease in high-income urban residents, but with no significant increase in risk among low-income or rural residents, suggesting socioeconomic context modifies the relationship between red meat intake and cardiovascular outcomes.

Why this might work

In wealthy city dwellers, eating more red meat increases saturated fat and iron in the blood, which triggers chronic inflammation and damages blood vessel lining, leading to heart attacks and strokes. In poorer or rural people, lower overall calorie intake and higher physical activity prevent this damage, so the same amount of red meat does not cause harm.

  1. Study: Red Meat Consumption and Risk of Cardio-Cerebrovascular Disease in Chinese Older Adults.

    In older Chinese people, eating more red meat raises heart and stroke risk for rich city dwellers, but not for poor or rural folks — and may even help them live longer. This shows where you live and how much money you have changes how red meat affects your health.
