Fibrinogen, a protein produced by the liver, plays a role in the development of atherosclerotic plaque. Fibrinogen can also cause acute blood clot formation that may block a coronary artery (causing a heart attack) or a cerebral artery (causing an ischemic stroke). I must admit I had not paid too much attention to this measure as when I last had it tested it came in at 309 mgdl which was well inside the OK range on the blood report I got back. This reference range tends to be 150 to 400 but some authorities are stating that there is evidence to support keeping it below 300. It is one of those factors that is not easily manipulated, the biggest effect coming from quiting smoking which in my case does not apply. Exposure to cold increases fibrinogen levels by 23 percent according to one study, perhaps adding weight to the fact that the further away from the equator you are the more likely to suffer from HD. Another study however has shown that Turmeric can have a significant effect on lowering Fibrinogen. I have already mentioned that a simple and easy way to up your Turmeric consumption is to add a little to your daily porridge. here is the link to the study that suggested Turmeric can help.
