If You Have Diabetes, Metabolic Syndrome, or Insulin Resistance Take Your Folic Acid

Recent study published in Obesity ((23 September 2010) | doi:10.1038/oby.2010.210) reveals exciting information about protecting the blood vessels of patients with diabetes, metabolic syndrome and insulin resistance.

It is a well known fact that excessive small blood vessel damage in these patients leads quickly to renal failure, macular degeneration (damage to the retina of the eye), and painful numbness and neuropathy in the hands and feet.  Patients with metabolic syndrome and diabetes have been shown to have increased levels of nitric oxide in their small blood vessels. This is thought to be one of the major causes of the damage that occurs in these patients. Much attention and monitoring is given to these patient in attempts to protect their blood vessels from ongoing damage.
Recent data showed that in just four weeks folic acid decreased the amount of nitric oxide present in the blood vessels of  patients with metabolic syndrome thereby implying significant vascular protection and health.  Further study is needed to determine the degree of protection folic acid renders in these patients, but until then, I'm taking my folic acid!!
