What are major dietary sources of Vitamin K?

• A. Whole grains and nuts
• B. Green leafy vegetables
• C. Fruits and dairy products
• D. Fish and eggs

Answer: (B)

Green leafy vegetables are indeed the major dietary sources of Vitamin K. This vitamin is crucial for the synthesis of proteins that are needed for blood coagulation and for the metabolism of bone proteins. Leafy greens such as kale, spinach, collard greens, and Swiss chard are particularly rich in Vitamin K1 (phylloquinone), which is the primary form found in the diet.

Incorporating these vegetables into your meals can significantly contribute to your daily Vitamin K intake. The other options, while they may contain various nutrients, do not provide substantial amounts of Vitamin K. Fruits can contribute some Vitamin K, but they are not as rich in this nutrient as green leafy vegetables. Whole grains and nuts, as well as fish and eggs, also contain minimal amounts of Vitamin K compared to the abundance found in leafy greens. This makes green leafy vegetables the best source for this essential nutrient.
