Best Food Facts recently received a question from a reader asking, "What foods contain Vitamin K? Why do we need Vitamin K?"
To answer the question, we reached out to Dr. Wendy Dahl, an assistant professor in the Food Science and Human Nutrition Department at the University of Florida.
Dr. Wendy Dahl
Dr. Dahl: "Many foods contain Vitamin K but the best food sources are leafy greens, especially kale, spinach, and turnip greens. Other good sources are broccoli, cabbage, and soybean oil. Vitamin K is a fat soluble vitamin that our bodies need for normal blood clotting. If we do not get enough Vitamin K, blood takes longer to clot, so there may be excessive blood loss when we get injuries. It is easy to get the recommended vitamin K each day. All you need is 1-2 servings of leafy greens each day or at least 2 servings of the other foods mentioned. The bacteria that normally reside in your large intestine also make Vitamin K that is absorbed by the body."
It seems Popeye really knew what he was doing with all that spinach consumption!
