Green leafy vegetables like kale, spinach, and collards are excellent sources of vitamin K. Some other foods that are rich in vitamin K include broccoli, Brussels sprouts, and green beans.

III. Nutrition 101: Understanding Vitamin K and Its Benefits for Overall Health:

A. Types of vitamin K and their functions:

There are two primary types of vitamin K: Vitamin K1 and K2. Vitamin K1, also known as phylloquinone, is found in plant foods, while vitamin K2, also known as menaquinone, is synthesized by bacteria in our colon. Vitamin K1 is essential for blood clotting, while vitamin K2 promotes bone health, prevents atherosclerosis, and lowers the risk of cancer.

B. Benefits of vitamin K for overall health:

Vitamin K has significant health benefits, including preventing osteoporosis, reducing the risk of heart disease, and improving cognitive function in older adults. Additionally, studies have found that vitamin K can help improve insulin sensitivity and lower the risk of diabetes.
