Letter vitamins step up for diabetes
In May researchers published the results of a 10-year study that followed 38,000 Dutch adults; those who got the most vitamin K in their diets were about 20 percent less likely to be diagnosed with type 2 diabetes during the study period.
While the researchers pointed out that this does not prove that the vitamin is the reason for the lower risk, it should fuel further research into whether it does play a role in the disease development. They also noted that there is evidence vitamin K reduces systemic inflammation, which could boost the body's ability to use insulin.
In the US, the RDA for vitamin K is 120mcg for men and 90mcg for women. In the study, participants with the highest intakes typically consumed between 250 and 360mcg.
In a presentation at Health Ingredients South America in 2009, director of DSM's global nutritional science group, Dr James Elliott, gave a presentation in which he highlighted the importance vitamin E may play.
Epidemiological studies have showed that diabetics often have decreased vitamin E levels. In a 2008 study, vitamin E supplementation appeared to reduce cardiovascular events in particular group of people with type II diabetes.
