Meat increases heart disease through the high iron stores says new 2014 study

Yet another unique aspect to meat is the high concentrations of heme iron.  This is very different to the non-heme iron in plant foods, such as leafy green vegetables.

What did the new study by the Indiana University School of Public Health-Bloomington find?

  • Heme iron consumption increased the risk for coronary heart disease by 57% 
  • The scientists discovered a VERY strong association between heme iron - found in meats - and potentially deadly coronary heart disease 
  • This meta-analysis, examined 21 previously published studies and data involving 292,454 participants during an average 10.2 years of follow-up
  • This study was unique because it looked at the associations of both types of total iron consumption - in comparison to the risk of coronary heart disease 

The researchers commented “There was no association between nonheme iron and coronary heart disease.  The only positive association involved the intake of heme iron.  Once absorbed, it may contribute as a catalyst in the oxidation of LDLs (Low-density lipoprotein or bad cholesterol), causing tissue-damaging inflammation, which is a potential risk factor for CHD”.

Remember; heme iron is only in animal foods and this is what was linked to the increased risk of heart disease.

Nonheme iron; only in plant foods, had no link with heart disease.

Just another reason to eat a plant-based wholefood diet.  

Study “Dietary iron intake and body iron stores are associated with risk of coronary heart disease in a meta-analysis of prospective cohort studies” by Hunnicutt J, He K, Xun P, as published in the January 8, 2014 online edition of the Journal of Nutrition.  Jacob Hunnicutt is a graduate student in the Indiana University School of Public Health-Bloomington’s Department of Epidemiology and Biostatistics.  The researchers did a meta-analysis, examining 21 previously published studies and data involving 292,454 participants during an average 10.2 years of follow-up.  This study was unique because it looked at the associations of both types of total iron consumption in comparison to the risk of coronary heart disease.  As reported by The Press Trust of India, IANS India Private Limited and business-standard.com on April 24, 2014.
