Foods High in Vitamin K You Can Easily Incorporate in Your Daily Diet

Are you looking for a reason to up your veggie consumption?

Look no further than vitamin K. If there was ever a big reason why you need to like broccoli and cabbage, that is vitamin K.

Now, these are not the only vitamin K foods, an important nutrient that can improve insulin sensitivity, reduce risk cancer, and help with blood clotting.

Vitamin K is a vitamin you can find in vegetables, fruits, meat, and fermented foods. In addition, our body produces vitamin K in the intestines and the gut.

What is vitamin K?

Vitamin K is just as important to our body as any other vitamin. It plays a role in almost everything from bone metabolism to blood clotting.

Vitamin K can be broken down into two main types, which are vitamin K1 and vitamin K2.

The former is the most common source of vitamin K, and is primarily found in plant foods like leafy greens. The latter, on the other hand, is found in animal products and fermented foods.

Having a vitamin K deficiency is rare if you follow a healthy and well-balanced diet. There is plenty of vitamin K if you consume whole foods.

However, if you consume ultra-processed foods and refined sugars, you might get little to no vitamin K. Therefore, you need to ensure that you get two servings per day of fruits and vegetables [1]https://ods.od.nih.gov/factsheets/VitaminK-HealthProfessional/.

Vitamin K rich foods

Let’s take a look at some of the best foods rich in vitamin K.

Why is vitamin K important for us?

Before we get to the benefits of vitamin K, and why we need this vitamin, we have to make a distinction between the two types of vitamin K. The two known types are vitamin K1 and vitamin K2.

Vitamin K1 is a vitamin found in vegetables. The plant vitamin can be sourced from leafy greens. Vitamin K2 is a different type of vitamin found in fermented dairy products.

Our body also produces vitamin K2 thanks to bacteria in the intestines and the gut. If you get enough of your daily vegetables, and you take care of your digestive health, you won’t have troubles with the absorption of vitamin K.

With that in mind, here are some vitamin K benefits you need to know.

Prevent and treat cancer

There is no clear cure for cancer, we know as much. But vitamin K can help by killing off cancer cells and reduce the risk of cancer.

A study at the University of Toronto showed that taking vitamin K could reduce the cancer incidence by 75%[2]https://www.ncbi.nlm.nih.gov/pubmed/18922041/0.

The reason why vitamin K helps is that it is mostly found in foods that are already rich in antioxidants. And we know antioxidants are the top cancer-fighting compounds.

Improve bone health

If you consume enough vitamin K rich foods, you will build strong bones. The vitamin is responsible not only for building stronger bones but maintaining healthy bones as well.

Vitamin K is involved in bone metabolism and increases the amount of protein needed to maintain calcium in the bones.

A couple of studies have shown that increased consumption of vitamin K can help reduce the risk of bone fractures and osteoporosis [3]https://www.ncbi.nlm.nih.gov/pubmed/12540415.

Low vitamin K levels are associated with loss and reduced bone mineral density. Therefore, if you want to prevent osteoporosis at old age, consume more vitamin K rich foods.

Help with blood clotting

The most well-known benefit and function of vitamin K is the role in promoting the formation of blood clots. Clotting is one of the most important processes in our body that prevents excessive bleeding as a result of an injury [4]https://www.ncbi.nlm.nih.gov/pubmed/24300958.

The first sign of low amounts of vitamin K is bleeding from the gums or nose along with easy bruising [5]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4862383/ .

One thing to know, vitamin K should be monitored when taking blood thinners. Thinners like Coumadin work against vitamin K, and dramatic increase or decrease in consumption of the vitamin can interfere with the effects of blood thinners.

Promote heart health

Vitamin K helps with blood clotting, but it also improves your heart health. There are other ways vitamin K helps your heart health.

For starters, vitamin K1 can slow the progression of coronary artery calcification in older adults [6]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2682995/.

K1 also has positive effects on vascular calcification. Coronary calcification is the strong predictor of coronary heart disease, and increasing your consumption of foods high in vitamin K can prevent its progression, and keep your heart healthy and strong.

Boost brain function

Vitamin K also plays a big role in the nervous system. According to studies, vitamin K supports healthy brain function, as it is involved in the metabolism of a class of compounds found in brain cell membranes that control motor and cognitive behavior [7]https://www.ncbi.nlm.nih.gov/pubmed/15869125.

Vitamin K also boosts some anti-inflammatory properties that protect the brain against oxidative stress.

Improve insulin sensitivity

Insulin is a hormone responsible for transporting sugar from the bloodstream to the tissues where it can be used as energy. When your diet is rich in sugar and carbs, your body will try to produce more and more insulin to keep it up.

Sadly, sustaining high levels of insulin can lead to a condition called insulin resistance, which is basically a pre-condition of diabetes type 2.

Do not think insulin is an unhealthy hormone. But high levels of insulin is something you want to avoid. Consuming more vitamin K helps you maintain normal blood sugar levels, which translates to normal insulin production levels [8]https://www.ncbi.nlm.nih.gov/pubmed/18697901/.

Vitamin K Deficiency

Vitamin K Deficiency symptoms

Our body requires vitamin K in small and regular amounts. The vitamin is essential for the formation of several substances called coagulation factors. They work together to clothe blood when injuries to blood vessels happen.

If you do not have enough vitamin K, you might experience excessive bleeding and easy bruising. The vitamin, as we saw before, also plays a role in the prevention of bone loss [9]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4862383/.

In the United States, dietary deficiency in vitamin K is rare in healthy individuals. However, those who suffer from chronic conditions are often at higher risk.

For example, patients admitted to intensive care units and cancer patients on chemotherapy are at higher risk of developing vitamin K deficiency [10]https://www.ncbi.nlm.nih.gov/pubmed/17923470.

Patients with diseases like chronic pancreatitis, Crohn’s disease, Celiac disease, cystic fibrosis, and other that impair absorption of nutrients can also suffer from deficiency.

Last, but not least, some medications can also cause vitamin K deficiency. Medications like anti-seizure medications, antibiotics, and antacids can interfere with the absorption of vitamin K and reduce the quantity of vitamin K2 in the intestines.

If you have low amounts of vitamin K, you might experience the following symptoms:

  • Easy bruising
  • Excessive bleeding from wounds and punctures
  • Heavy menstrual periods
  • Oozing from nose or gums
  • Bleeding from the gastrointestinal tract
  • Blood in urine and or stool

Vitamin K deficiency is often at newborns, which is why they receive a vitamin K injection after they are born [11]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3021393/.
