The link between heart disease, gut health and your microbiome

It can be very worrying when you’ve got heart disease or are at high risk of having a stroke or a heart attack. While the traditional risk factors for heart disease such as high cholesterol, high blood pressure, and smoking are well-known, emerging research has shed light on a fascinating connection between gut health, the gut microbiome, and the development of cardiovascular conditions. This link has opened up new possibilities for managing heart disease through the field of nutritional therapy.

Understanding the gut microbiome

The human gut is home to trillions of microorganisms collectively known as the gut microbiome. These bacteria, viruses, fungi, and other microbes play a crucial role in maintaining overall health and are intricately connected to various bodily functions, including digestion, immunity, and metabolism. Recent studies have demonstrated that imbalances in the gut microbiome, known as dysbiosis, can contribute to the development and progression of heart disease.

One of the key mechanisms linking gut health and heart disease is through chronic inflammation. Imbalances in the gut microbiome can trigger an inflammatory response, leading to the release of pro-inflammatory molecules into the bloodstream. These molecules can promote the development of atherosclerosis, a condition characterised by the build up of plaque in the arteries, which can eventually lead to heart attacks or strokes.

Cholesterol metabolism and the gut microbiome

Furthermore, the gut microbiome has been found to influence cholesterol metabolism. Certain species of bacteria in the gut can metabolise bile acids, which are essential for the digestion and absorption of dietary fats. Imbalances in the gut microbiome can alter the metabolism of bile acids, leading to elevated levels of cholesterol in the blood. High cholesterol is a risk factor for heart disease for some people, emphasising the importance of maintaining a healthy gut microbiome for cardiovascular health.

The role of nutritional therapy in heart health

Nutritional therapy is an evidence-based approach to using food and nutrients for therapeutic purposes and offers a promising avenue for managing heart disease by targeting gut health and the gut microbiome. Nutritional therapists can help clients with heart disease develop a personalised dietary strategy to support gut health and reduce the risk of cardiovascular complications.

1. Heart-healthy nutrients

One of the key aspects of nutritional therapy for heart disease involves optimising the intake of heart-healthy nutrients. For example, omega-3 fatty acids, found in fatty fish, flaxseeds, and walnuts, have been shown to have anti-inflammatory properties and can help reduce the risk of heart disease. A nutritional therapist can provide guidance on incorporating these nutrient-rich foods into the diet to support gut health and lower inflammation.

2. Fibre-rich foods

Fibre is essential for a healthy gut microbiome. Fruits, vegetables, whole grains, and legumes, are also crucial for maintaining a healthy gut microbiome. The gut bacteria ferment dietary fibre and produce short-chain fatty acids, which have been associated with a reduced risk of heart disease. A nutritional therapist can work with individuals to increase their fibre intake and create meal plans that prioritise gut health and cardiovascular well-being.

3. Targeted supplements

In addition to dietary modifications, nutritional therapy may also involve the use of probiotics and prebiotics. Probiotics are live beneficial bacteria that can be consumed through certain foods or supplements, while prebiotics are non-digestible fibres that serve as food for these beneficial bacteria. Both probiotics and prebiotics can help restore the balance of the gut microbiome and improve overall gut health. I can recommend appropriate probiotic strains and prebiotic sources based on an individual's specific health needs and heart disease risk factors.  I also often arrange functional lab testing to work out, rather than guess, what your specific requirements are. 

The benefits of seeing a nutritional therapist

Some of the key ways nutritional therapists help clients with heart disease, such as high blood pressure, is to undertake a comprehensive assessment of their dietary habits, gut health status, and cardiovascular risk factors to create personalised nutrition plans that target specific needs, tailored to your needs.

Furthermore, a nutritional therapist can provide ongoing support and monitoring to ensure the successful implementation of dietary interventions. We can help you navigate challenges, answer questions, and provide evidence-based recommendations tailored to your unique circumstances. 

The link between gut health, the gut microbiome, and heart disease has opened up exciting possibilities for managing cardiovascular conditions and seeing a nutritional therapist can help you take proactive steps towards improving your gut health and overall cardiovascular well-being.
