This really depends on what foods you consume as part of your daily diet. Both vegetarians and non-vegetarians can regularly eat foods such as collards, turnip greens, spinach, kale, broccoli, soy, prunes, and pumpkin – which are all excellent sources of vitamin K. You can enjoy these foods in many dishes – for instance, spinach in a lupini bean salad and prunes in homemade prune jam. Good sources of vitamin K include blueberries, chicken breast, grapes, cashews, and olive oil. I like to add blueberries to a blueberry peanut butter smoothie and grapes to a Greek yogurt parfait.
