It is said that love goes through the stomach. Modern science today goes a step further and says: the way to the heart is through the intestines . And not symbolically, but very concretely – through metabolism, inflammation and the functioning of blood vessels.
Cardiovascular disease remains the leading cause of death, despite decades of advice about “healthy eating,” exercise, and cholesterol control, but in recent years it has become increasingly clear that there is another important factor in the story: the gut microbiome .
The gut and the heart are not separate systems. They are connected by a complex network of metabolic and immune signals. The microbiome – the community of microorganisms in our gut – actively participates in the regulation of:
inflammatory processes
fat and glucose metabolism
blood vessel functions
When the microbiome is diverse and stable, it acts as a protective factor. When it is out of balance (dysbiosis), it can promote chronic, low-grade inflammation – the silent underpinning of many cardiometabolic diseases.
One of the key mechanisms of the connection between the gut and the heart is systemic inflammation .
If the intestinal barrier is weakened, certain bacterial components can more easily enter the bloodstream and activate an immune response.
Such long-term, mild inflammation:
puts a strain on the blood vessels
accelerates atherosclerotic processes
can affect blood pressure and cholesterol levels
In other words – the state of your gut has very real consequences for heart health.
One of the most researched microbiome metabolites in the context of heart health is TMAO (trimethylamine-N-oxide) .
Certain intestinal bacteria from nutrients such as choline and carnitine (present in red meat, eggs and some protein sources) produce trimethylamine, which is converted to TMAO in the liver.
Elevated TMAO levels are associated with:
higher risk of atherosclerosis
increased cardiovascular risk
worse long-term outcomes for heart health
It’s important to emphasize: it’s not the food itself that’s the problem , but the way your microbiome metabolically processes it.
The microbiome doesn’t just produce potentially harmful compounds. It also creates short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate.
These compounds:
strengthen the intestinal barrier
reduce inflammatory processes
participate in the regulation of blood pressure
have a beneficial effect on fat and sugar metabolism
Butyrate stands out as a key gut “protector” and an important ally for heart health. Its production is most stimulated by dietary fiber intake .
Heart health can no longer be viewed solely through the numbers on a test report. It requires a comprehensive approach. approach , in which the intestines play a central role.
Microbiome support includes:
a varied, plant-based diet rich in fiber
moderation in ultra-processed foods
regular movement
quality sleep and stress management
personalized recommendations based on real data
There is no one “heart-healthy” diet that works for everyone. The individual response of the body depends largely on the composition of the microbiome.
Gut microbiome analysis allows:
insight into the balance of bacteria
assessment of inflammatory and metabolic potential
more precise dietary and lifestyle guidelines
Taking care of your health is not a short-term decision, but a long-term relationship with your body.
If we want a strong, resilient, and healthy heart, it’s time to pay more attention to our intestines.
Too much sugar encourages the growth of bacteria that disrupt the balance of the microbiome and promote inflammation.
Antibiotics are sometimes necessary, but at the same time they significantly change the composition of the microbiome. After therapy, it is important to think about intestinal recovery.
Long-term and frequent use of NSAIDs can weaken the intestinal barrier and negatively affect the microbiome.
Regular physical activity increases the diversity of the microbiome and promotes the growth of beneficial bacteria.
Smoking negatively affects both the heart and the gut. Quitting smoking allows for the gradual recovery of the microbiome.
