Potassium is a mineral, necessary for proper cell, tissue and organ function, as well as an electrolyte, which conducts electricity in the body. Vitamin K is essential for coagulation and the absorption of calcium in the bones. Certain foods are high in both potassium and vitamin K.
Avocados
Avocados from California are abundant in markets during the spring and summer, while Florida-grown avocados reach store shelves in October. An 8-oz. serving of avocado gives you 35 percent of your daily value for vitamin K and almost 25 percent of the daily value for potassium. The daily value, developed by the Food and Drug Administration, is a nutritional recommendation for the percentage of a specific nutrient that a person should consume daily. The American Heart Association acknowledges the significance of eating a healthy diet that includes foods high in potassium and calcium in lowering blood pressure. Avocados are a rich source of dietary fiber, healthy monounsaturated fatty acids and folate.
Green Beans
While green beans are available in markets throughout the year, they are in peak season from summer to early autumn. Picked before the inner bean matures, green beans are one of the few beans that are eaten fresh -- pod and all. According to the World's Healthiest Foods website, one cup of green beans supplies 25 percent of the daily value for vitamin K. The same serving size provides 10 percent of the daily value for potassium. Green beans are a rich source of vitamins A and C, magnesium and dietary fiber. Together with potassium, magnesium helps lower blood pressure.
Brussels Sprouts
If you want to get maximum nutritional benefits from Brussels sprouts, steam them for only five minutes. A member of the cruciferous family of vegetables, Brussels sprouts have antioxidant and anti-inflammatory properties. They are high in vitamins K and C. One cup of cooked Brussels sprouts supplies you with 50 percent of the daily value for vitamin K and close to 15 percent of the daily value for potassium. Ongoing research at Tufts University is looking at the role of vitamin K in the inflammation process.
