Increased intakes of vitamin K1 may lower the risk of developing type-2 diabetes in elderly people with a high risk of cardiovascular disease, says a new study.
There is an irony in these results. Most people over the age of 60 with a risk of cardiovascular disease (and virtually all people over 75) are prescribed warfarin, a blood thinning medication.
Vitamin K contributes to clotting. In patients on warfarin, Vitamin K intake is discouraged to make it easier to regulate medication levels and maintain a proper blood flow.
Vitamin K is found in many vegetables with additional health properties such as broccoli and leafy greens. If an increase in this vitamin could help lower the risk of diabetes, some patients may have to make a decision whether they can properly regulate their levels on warfarin.
