The Study
High Meat Intake and Ferritin Levels in Relation to Cardiovascular Risk Among Individuals with Diabetes in Mongolia
This study took a snapshot of people's diets and blood tests at one time. It can show that eating more meat is linked to higher ferritin levels, but it can't prove that meat caused the change. It's like seeing two things together, but not knowing which one came first or if something else caused both.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Even though high meat intake raised iron and some heart risk markers, it didn't trigger inflammation, suggesting the iron came from food, not disease.
- 2People who ate the most meat had twice as high iron stores (ferritin: 275.6 vs 119.6 ng/mL).
- 3They also had higher 'bad' cholesterol and a higher chance of heart disease in the next 10 years (14% vs 11%).
- 4But their bodies didn't show more inflammation.

If you're a Mongolian adult with type 2 diabetes and have high levels of a protein called ferritin in your blood, you might be at greater risk for heart problems over the next 10 years — and this seems to be true even if your other signs of inflammation are normal.
In Mongolian adults with type 2 diabetes, eating meat affects both ferritin levels and heart disease risk, but ferritin doesn’t seem to be the reason for that link.
If you're a Mongolian adult with type 2 diabetes and eat a lot of meat, your body might store more iron — and this could be because meat adds extra iron to your system.
In Mongolian adults with type 2 diabetes, people with more stored iron in their bodies tend to have higher 'bad' and total cholesterol levels — which might mean how the body stores iron affects cholesterol.
In Mongolian adults with type 2 diabetes, high ferritin levels don’t seem to be linked to body-wide inflammation — they might just come from eating a lot of iron-rich foods instead.
Eating only meat gives your body enough of the right kind of iron to keep your iron levels and blood counts healthy—without too little or too much iron.
