An oily fish diet increases insulin sensitivity compared to a red meat diet in young iron-deficient women

Authors: Santiago Navas-Carretero, et al. / Journal: British Journal of Nutrition, August 2009


Researchers followed 25 young iron-deficient women to compare how two diets – one rich in oily fish, the other rich in red meat – affect several factors linked to type 2 diabetes. The study found that insulin levels were nearly 20 percent lower with the oily fish diet than with the red meat diet and iron status was similar in both groups, suggesting oily fish is a source of iron that may have additional insulin sensitivity benefits.
