A staggering 90% of Canadians possess one or more risk factors for heart disease and stroke. The good news is that many instances of early cardiovascular disease can be averted. Emerging studies highlight a crucial, yet often neglected, element that can enhance your chances of avoiding heart disease and boosting your general health: the connection between the heart and gut.

The Role of Your Gut Microbiome in Heart Health
Research indicates that many adults suffer from poor gut health, with prevalent symptoms such as bloating, cramping, and abdominal discomfort showing a significant need for improvement in gut wellness.
Moreover, Canada reports some of the highest rates of gut health-related disorders, such as inflammatory bowel disease (IBD). This trend is concerning, with an increasing number of Canadians diagnosed with IBD at alarming rates.
In tandem, Canada also reports high occurrences of cardiovascular disease. These two trends may indeed be interconnected.
“The gut microbiome significantly impacts heart health by producing compounds like trimethylamine-N-oxide (TMAO) and phenylacetylglutamine (PAG), which influence inflammation and the functionality of the heart and blood vessels,” explains Sean Ormond, MD.
For instance, one research study revealed that disbalance of healthy gut bacteria due to antibiotics, dietary changes, or other factors could lead to heightened inflammation across various diseases—not just cardiovascular issues such as heart failure, type 2 diabetes, high blood pressure, and atherosclerosis, but also autoimmune conditions like rheumatoid arthritis and lupus.
“While research is ongoing, evidence suggests a healthy gut can decrease the risk of heart disease,” adds Ormond. Studies indicate that maintaining gut health can bring about:
- Enhanced cholesterol levels
- Improved blood pressure regulation
- Optimized fat metabolism
- Healthier heart contractions and consistent heartbeat maintenance (irregular heartbeats, known as arrhythmias, are often linked to heightened risks of cardiovascular disease and severe heart attacks or strokes)
The connection between gut health and heart health stems from beneficial bacteria producing key chemical compounds and a healthy gut’s enhanced ability to process and digest food. Many lifestyle factors affecting gut health are also related to heart health.
Consider smoking, for example, which is a significant heart disease risk factor. Smokers show increased levels of harmful gut bacteria compared to non-smokers, similar to those with IBD.
This mutual relationship between gut and heart health offers insights on how lifestyle changes can effectively enhance both.

Enhancing Your Lifestyle for Better Heart-Gut Health
Your gut health and heart health are closely linked, and practices that benefit your cardiovascular health often enhance gut health too. Many of these health influences are intertwined, enabling you to address both major health concerns through practical lifestyle changes.
“There are several easy steps you can take to boost both your gut and heart health,” advises Ormond. “Diet plays a pivotal role.”

Increase Your Fiber Intake
“Consuming high-fiber foods like fruits, vegetables, and whole grains boosts gut health and reduces the harmful substances associated with heart disease,” notes Ormond.
Fiber not only benefits gut health but is also closely tied to better cardiovascular health. A study conducted in India involving participants on a high-fiber diet for six months revealed a 15% reduction in systolic blood pressure, along with 28% lower blood sugar levels and a 23% decrease in triglyceride levels.

Reduce Processed Foods
“Cutting back on processed foods is beneficial for your heart as well as your gut,” emphasizes Ormond. Processed foods can disrupt the gut microbiome, leading to higher levels of inflammation and are closely tied to an increase in heart disease.

Incorporate More Fermented Foods
Ormond particularly suggests yogurt and sauerkraut, which help cultivate beneficial bacteria in your gut and contribute to improved cholesterol levels and other heart disease risk factors.

Commit to Regular Exercise
Regular physical activity is an effective way to reduce the risk of heart disease while enhancing the diversity and quantity of beneficial gut bacteria.

Stay Hydrated
Maintaining adequate hydration promotes healthy digestion and supports the balance of bacterial and immune functions in the gut.

Detoxify Your Lifestyle
This entails focusing on organic foods, using HEPA-rated air filters, and minimizing exposure to toxic household chemicals, as environmental toxins are associated with detrimental gut health and an elevated risk of cardiovascular disease.

Practice Good Hygiene
Regular handwashing can significantly reduce the risk of introducing harmful bacteria into your gut. Limit the use of antibiotic cleaners and other harsh cleaning supplies to when absolutely necessary, as these can disrupt the beneficial bacteria in your gut.
