Micronutrients & recovery
A higher dietary zinc-to-heme iron ratio is significantly associated with a lower risk of type 2 diabetes, suggesting that the balance between these minerals matters more than zinc intake alone.
Pay attention to the balance of zinc and iron in your diet. This study found that a higher ratio of dietary zinc to heme iron is linked to a significantly lower risk of type 2 diabetes. This suggests that ensuring adequate zinc intake while managing heme iron consumption (found in red meat) may be more important for diabetes prevention than zinc intake alone.
GoodSupportsHIGH confidence
We further found an inverse association for dietary zinc to heme iron ratio... The RR for highest quintile versus lowest quintile was 0.75 (95% CI 0.66 – 0.85) (Ptrend < 0.0001).
Why this rating
Strong statistical significance (P<0.0001) and robust sensitivity analysis, but still observational.
