Gut bacteria may reduce cholesterol and lower heart disease risk: Expert

New Delhi: Heart health or cardiovascular diseases are a major health concern across the globe, with several contributing factors leading to the condition. One intriguing aspect is the relationship between gut health and cardiovascular well-being. Research shows that maintaining a healthy gut microbiota can influence cholesterol levels and reduce the risk of heart disease.

The Role of Gut Health in Heart Disease

Dr Anesh Jain, Cardiologist from Ruby Hall Clinic, Pune shared with News9“Good oral hygiene is crucial for overall health, starting with your teeth. Conditions such as toothaches or gingivitis can create a state of chronic inflammation, which may contribute to heart disease. Inflammation in the mouth can lead to systemic effects that compromise heart health.”

“Moreover, the gut microbiota—comprising trillions of microorganisms in our digestive system—plays a pivotal role in our health. These gut bacteria not only protect our bodies but also produce short-chain fatty acids when we digest food. These fatty acids influence various bodily functions, including the regulation of cholesterol.”

Cholesterol and Gut Bacteria

Cholesterol in our bodies comes from two primary sources: the liver produces cholesterol, while the food we consume contributes additional cholesterol. According to Dr Jain, “Gut bacteria affect how this cholesterol is absorbed. Alterations in gut microbiota, including the presence of beneficial and harmful bacteria, can significantly impact cholesterol levels. When the balance shifts toward harmful bacteria, the body may absorb more bad cholesterol, increasing the risk of cardiovascular issues.”

Recommendations for Heart and Gut Health

To promote good gut health and maintain healthy cholesterol levels, several lifestyle changes are recommended:

1. Regular Exercise: Physical activity is essential for overall health. You don’t have to engage in high-intensity workouts; even daily walking can make a significant difference.

2. Healthy Diet: Emphasising a diet rich in natural, home-cooked foods can help maintain gut health. Avoid processed foods, which often contain high levels of salt and sugar that can negatively affect gut bacteria.

3. Antibiotic Use: Be cautious with over-the-counter antibiotics. While necessary at times, they can disrupt gut flora, leading to imbalances.

4. Routine Check-ups: Monitoring cholesterol levels is vital, especially for individuals under 40 with a family history of heart disease. It is advisable to check cholesterol levels at least once before 40, and every 2-3 years after that.

Gut health is integral to heart health, and the relationship between gut microbiota and cholesterol levels is becoming increasingly clear. By prioritising a balanced diet, regular exercise, and responsible antibiotic use, you can support both your gut and cardiovascular health. These lifestyle changes can lead to a healthier, pharmacy-free life for many years to come.
