Consuming red meat and other foods high in 'heme' iron, such as chicken liver, clams and oysters, appears to increase the risk of heart disease in diabetics, researchers report in the journal Diabetes Care
It might be advisable that "patients with type 2 diabetes may limit consumption of heme iron and red meat," lead investigator Dr. Lu Qi told Reuters Health.
Dr. Qi of Harvard School of Public Health, Boston and colleagues note that diabetes-related metabolic abnormalities may aggravate the adverse effects of excess iron on the heart. However, they add, little is known about whether iron consumption also affects heart disease risk.
To investigate further, the researchers followed 6,161 women participating in the Nurses' Health Study, and who reported a diagnosis of type 2 diabetes. During follow-up from 1980 through 2000, the team documented 550 new cases of heart disease.
