Gut bacteria, or gut microbiota, is composed of a host of different microorganisms including bacteria, fungi, viruses, and other microbes that live in our digestive tracts. These microbes play a vital role in our overall health, including our cardiovascular health.

The Role of Gut Bacteria in Artery Health

1-Gut Bacteria and Artery Health

Our arteries, the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body, are crucial for our survival. The lining of the arteries, called the endothelium, plays a vital role in maintaining artery health.

Research indicates that gut bacteria can influence the health of the arteries. For instance, certain harmful bacteria in the gut can produce toxins, such as trimethylamine N-oxide (TMAO), from the breakdown of nutrients like choline and carnitine from our diet. Elevated levels of TMAO in the blood have been associated with increased risk of atherosclerosis, a condition characterized by the buildup of plaque in the arteries, leading to narrowed or blocked arteries.

On the other hand, beneficial gut bacteria, often promoted by a high-fiber diet rich in fruits and vegetables, can produce anti-inflammatory substances and SCFAs that have positive effects on the arteries. They can reduce inflammation and oxidative stress, enhance the endothelial function, and prevent plaque buildup in the arteries.

How Gut Microbiota Imbalance Can Affect Our Arteries

The gut microbiota, also known as the gut flora, consists of trillions of microorganisms residing in our digestive tract. This includes various species of bacteria, viruses, fungi, and other microbes. A balanced gut microbiota is vital for our overall health as it plays an essential role in digestion, metabolism, immune function, and even mental health.

However, when there’s an imbalance in this delicate ecosystem, often referred to as gut dysbiosis, it can lead to various health issues. One of these issues, surprisingly, is related to our arteries’ health.

2-The Significance of Vitamin K2 in Maintaining Healthy Arteries

Artery Health

Vitamin K2, a member of the vitamin K family, is a lesser-known but incredibly essential nutrient when it comes to maintaining the health of our arteries. The primary role of Vitamin K2 is to regulate calcium in the body – ensuring that it goes to the right places, like our bones and teeth, and stays away from the areas where it can cause harm, such as our arteries and soft tissues.

Vitamin K2 and Arterial Health

When it comes to arterial health, Vitamin K2’s role in calcium regulation becomes crucial. In a healthy body, Vitamin K2 activates proteins that inhibit calcium from depositing in the arteries. This is significant because calcium deposits in the arteries can contribute to the formation of atherosclerotic plaques, which are essentially build-ups of fats, cholesterol, and calcium in the artery walls.

Atherosclerotic plaques can cause the arteries to narrow or become blocked, restricting blood flow and potentially leading to heart attacks or strokes. Thus, Vitamin K2’s role in keeping calcium out of the arteries is fundamental in maintaining healthy arteries and overall cardiovascular health.

Vitamin K2 Deficiency and Arterial Health

If a person is deficient in Vitamin K2, they may be at a greater risk of arterial calcification and the subsequent cardiovascular issues it can cause. Calcium can begin to accumulate in the arteries, contributing to the formation of atherosclerotic plaques and increasing the risk of arterial blockage.

Optimizing Vitamin K2 Intake

Ensuring adequate intake of Vitamin K2 can support arterial health by helping prevent arterial calcification. Vitamin K2 can be found in certain animal-based and fermented foods. Some of the richest sources include natto (a fermented soy product popular in Japan), certain cheeses like Gouda and Brie, and organ meats. It’s also available in supplement form, often in combination with Vitamin D, as these two vitamins work synergistically for optimal bone and cardiovascular health.

However, as with any supplement, it’s important to consult with a healthcare provider before starting a regimen to ensure it’s appropriate and safe based on individual health circumstances.

In summary, Vitamin K2 plays a significant role in maintaining the health of our arteries by regulating calcium in the body and preventing it from accumulating in our arteries. By ensuring adequate intake of this vital nutrient, we can support the health of our arteries and reduce the risk of cardiovascular disease.

3- Foods Rich in Vitamin K2

Artery Health

But do you know what produces Vitamin K2? Microbes. Our own gut produces Vitamin K2. It can convert Vitamin K1 from green leafy vegetables into Vitamin K2. Additionally, Vitamin K2 can be found in fermented foods, especially fatty cheeses.

Why Fermented Foods Are Rich in Vitamin K2

Fermented foods are rich in Vitamin K2 because the bacteria present in these foods can produce Vitamin K2. Thus, the fattier the cheese, the more Vitamin K2 you’ll get.

The Resistance of Conventional Medicine Towards Foods Rich in Saturated Fats

Interestingly, conventional medicine advises you to avoid saturated fats and cholesterol-rich foods, which are precisely those that contain Vitamin K2, the antidote against calcium accumulation.

4-The Relationship Between Gut Bacteria and Artery Inflammation Control

Artery Health

Gut bacteria are atheroprotective, meaning, they protect against the hardening of arteries, calcium buildup, and plaque formation.

The Risks of a Sterile Food-Based Diet

But what happens if our diet is based on sterile foods? I’m talking about pasteurized and cooked foods that kill all the microbes and foods that contain antibiotics.

The Effects of Antibiotics on Our Gut Microbiota

When you eat animals that have consumed antibiotics, you kill both the good and bad microbes in your gut, and the surviving microbes become resistant, leading to all sorts of side effects, like inflammation.

The Role of Raw and Fermented Foods in Our Health

Raw and fermented foods, like fermented vegetables, are a great source of friendly microbes. They not only add more microbes to your existing microbiota but are also easier to digest because they are pre-digested by the microbes.

5- An Ideal Meal for Artery Health

So, what would be a really good meal that would help with your arteries? I’m talking about a plate with Brie cheese, fatty pork sausage, and sauerkraut.

Why Is This Meal Beneficial for the Arteries?

Each of these ingredients is loaded with Vitamin K2. Plus, all are fermented, meaning that bacteria have acted on these foods to enhance nutrient availability and digestibility. Also, each of them is not sterile, they contain microbes that you can use in your own body.


Therefore, the next time you go to the grocery store, start looking at foods from the viewpoint of how many foods are really sterilized, pasteurized, and over-processed. Make a switch to start purchasing foods that are more alive, more fermented, and more enhanced with this fermentation process.

Frequently Asked Questions

1. What is Vitamin K2 and why is it important for our arteries?

Vitamin K2 plays a crucial role in directing calcium into our bones and teeth, and away from our arteries and soft tissues. Its deficiency could lead to calcium build-up in the arteries, increasing the risk of atherosclerosis and heart diseases.

2. How can fermented foods benefit our health?

Fermented foods are rich in probiotics, which can help balance our gut microbiota and support digestive health. They also improve nutrient availability and digestibility. Some fermented foods are also a great source of vitamin K2.

3. What are the risks of a diet based on sterile foods?

A diet based on sterile foods like pasteurized and cooked foods can kill both good and bad microbes in our gut, disrupting the delicate balance of our gut microbiota. This may lead to a series of side effects including inflammation, and a deficiency of essential nutrients like vitamin K2.

4. How can we incorporate fermented foods into our diet?

There are many ways to incorporate fermented foods into our diet. Foods like Brie cheese, fatty pork sausage, and sauerkraut are not only loaded with vitamin K2 but also contain probiotics and other beneficial nutrients.

5. How can diet help prevent heart disease?

Maintaining a balanced diet that includes nutrient-dense foods like fermented foods rich in vitamin K2 can help maintain healthy arteries and prevent heart disease. Regular exercise and a healthy lifestyle also play a critical role in heart disease prevention.
