A study completed at the UK’s University of Cambridge School of Clinical Medicine recently examined the relationship between iron and the incidence of type 2 diabetes. Researchers studied the association of serum iron, transferrin, TSAT, and ferritin in over 11,000 cases and over 15,000 controls. After making a variety of adjustments, including age, BMI, smoking status, and others, it was found that higher levels of both ferritin and transferrin led to an increased type 2 diabetes risk.
This information shows the importance of regulating iron levels to prevent type 2 diabetes. It is also important to note that higher levels of ferritin and transferrin were linked to a greater diabetes risk in both men and women while higher TSAT levels were only linked to an increased risk in women.
These findings were published in Diabetes Care on February 9, 2016.
