Poor Gut Health and Its Role in Cardiovascular Disease - Balance ONE

Can gut health affect your heart? Absolutely, yes. 

Studies reveal a deep connection between gut health and cardiovascular disease, explaining how gut microbiota—those trillions of bacteria in our digestive system—influence heart health. 

You might have heard the saying, "trust your gut." 

But when it comes to heart health, trusting your gut takes on a whole new meaning. 

Key Takeaways

  • Poor gut health is linked to increased risks of cardiovascular disease, largely through inflammation.
  • Dysbiosis, or gut imbalance, can lead to artery plaque buildup and cardiovascular disease.
  • Ingesting or supplementing probiotics and prebiotics may support heart health by maintaining a balanced gut microbiome.

The Role of Gut Microbiota in Metabolic Health

To understand how gut health affects your heart, we have to start with the role of gut microbiota in overall metabolic health. These bacteria aren't just passive inhabitants; they play active roles in breaking down food, managing metabolism, and supporting the immune system

A balanced gut microbiome supports metabolic processes that help keep the heart working day in and day out. 

Problems begin when this balance is thrown off, like with dysbiosis, as it can lead to metabolic dysfunction. These imbalances can create a domino effect leading to health problems and setting the stage for cardiovascular disease.

How The Gut Microbiome Impacts Cardiovascular Disease

What’s the gut-heart connection? It’s mostly about the compounds that the gut bacteria produce. Some microorganisms in the gut create substances that enter the bloodstream and influence heart health. 

One such compound is trimethylamine N-oxide (TMAO), which is linked to higher risks of heart disease. 

When TMAO levels rise, so does the risk of artery-clogging plaques. This can lead to heart attacks and strokes. This link isn’t just theoretical; studies have shown that people with higher TMAO levels face greater cardiovascular risks.

Inflammation

An imbalanced gut can trigger widespread inflammation, which is a known contributor to various heart problems. Chronic inflammation can damage blood vessels, making them more likely to accumulate plaque and narrow over time. This narrowing can restrict blood flow, increasing the risk of heart attacks and other serious cardiovascular events.

Harmful Metabolites

When gut bacteria break down certain foods, such as red meat or eggs, they can produce compounds that aren’t normally bad for you, but can be harmful in large amounts. These compounds, once in the bloodstream, can contribute to the development of atherosclerosis, or the thickening and hardening of the arteries. 

That makes it harder for the heart to pump blood, increasing the risk of heart disease.

Blood Pressure

Even blood pressure isn’t immune to the effects of an unhealthy gut. The gut microbiome influences blood pressure regulation by producing chemicals that affect how blood vessels function.

Bacterial imbalance can disrupt this regulation, leading to higher blood pressure. Elevated blood pressure is a significant risk factor for heart disease, demonstrating yet another pathway through which gut health impacts cardiovascular health.

Causes of Poor Gut Health

What can lead to these imbalances in the gut? Several factors can disrupt gut balance: 

  • Diet is a major one—consuming a lot of high-fat, high-sugar foods can quickly disrupt gut balance. We’re only as healthy as what we eat, and it couldn’t be any more true when it comes to the heart.
  • Antibiotics, while necessary to fight infections, can also wipe out beneficial bacteria, leaving the gut vulnerable. It’s why many experts recommend taking probiotics while you’re taking antibiotics (but getting the  timing right is crucial too).
  • Chronic stress affects gut health and, consequently, overall well-being. Having butterflies in your stomach might just be a sign that you’re too stressed to function, and it might be subtly affecting your heart.

Signs of an Imbalanced Microbiome (Dysbiosis)

How can you tell if your gut is out of balance? Common signs of an imbalance microbiome include digestive problems like bloating, constipation, or diarrhea. An imbalanced gut can lead to fatigue, inflammation, or immune system dysfunction.

Role of Probiotics in Restoring Gut Balance

Probiotic bacteria maintain balance in the gut, keeping harmful bacteria and yeast in check. 

Specific species of these helpful bacteria, such as various strains of human-origin bacteria like Lactobacillus and Bifidobacterium, play a pivotal role in maintaining heart health.

These strains are known to reduce inflammation, lower blood pressure, and improve cholesterol levels. Many of these strains can be found in probiotic supplements like Balance ONE.

For example, Lactobacillus plantarum has been shown to enhance blood flow and reduce systemic inflammation.

Foods Rich in Prebiotics

To keep these probiotics thriving, they need nourishment—prebiotics, to be precise. Prebiotics are like the high-octane fuel for your gut bacteria, helping them thrive and function optimally. 

Here are a short list of prebiotics-rich foods:

  1. Chicory Root: Packed with inulin, this root supports digestion and keeps constipation at bay.
  2. Garlic and Onions: More than just flavor enhancers, these are prebiotic powerhouses, fostering the growth of Bifidobacteria.
  3. Asparagus and Leeks: These vegetables contain inulin and help break down fats.
  4. Bananas: Especially when unripe, bananas are high in resistant starch, beneficial for gut health.
  5. Whole Grains: Barley and oats are not just for breakfast; they contain beta-glucan, which can lower bad cholesterol and promote a healthy gut.

Which Foods to Avoid

There are gut-friendly foods and not-so-gut-friendly foods. In this case, these “bad” foods can also harm your heart. 

Processed foods, high sugar intake, and trans fats can disrupt the gut microbiota balance, leading to increased inflammation and the production of harmful metabolites like TMAO. This compound is bad news, and is directly linked to higher risks of heart attacks and strokes. 

Final Thoughts

By understanding and maintaining gut health, you can take proactive steps to support both your digestive and cardiovascular systems. A healthy gut contributes to a healthier heart, making it vital to pay attention to what you eat, how you manage stress, and the balance of your internal ecosystems.

FAQs

Can Poor Gut Health Cause Heart Palpitations?

Imbalances in gut bacteria can trigger inflammation and hormonal changes, which may lead to irregular heartbeats. Your gut isn't just about digestion; it communicates with your heart through various pathways that can impact its rhythm. If your heart's skipping a beat, look to your gut.

Can Gut Health Affect Physical Performance?

A healthy gut fuels your body with the nutrients it needs, optimizing energy levels and muscle function. On the flip side, a compromised gut can lead to nutrient deficiencies and chronic fatigue, leaving you sluggish and underperforming.

Should People with High Blood Pressure Take Probiotics?

Probiotics can help to balance your gut microbiota, which in turn can influence blood pressure regulation. Some studies have shown that specific strains like Lactobacillus can reduce systolic blood pressure. 

It's a good idea to consult with your healthcare provider before starting any new supplement regimen, especially if you're managing high blood pressure.

Are Gut Bacteria Linked to Fatty Deposits in Heart Arteries?

Yes, gut bacteria can produce compounds like TMAO that contribute to the formation of artery-clogging plaques. A disrupted gut microbiome can increase TMAO levels, promoting atherosclerosis and raising the risk of heart attacks.
