When it comes to heart health, many people focus on traditional methods like exercise and a healthy diet. However, recent studies have shown that there is a new player in the game of heart health: probiotics. Yes, those tiny bacteria that live in our gut can actually have a significant impact on the health of our heart. In this blog, we will explore the benefits of probiotics for heart health and how they work.
What are probiotics?
Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. They are often called "good" or "friendly" bacteria because they help keep your gut healthy. You can find probiotics in certain foods like yogurt and sauerkraut, and also in supplement form.
How do probiotics affect heart health?
Research has shown that probiotics can help improve heart health in several ways:
Lowering blood pressure:
Probiotics have been found to have a modest effect on reducing blood pressure, particularly in people with hypertension. One study found that daily consumption of probiotics for 8 weeks resulted in a significant reduction in systolic blood pressure in people with high blood pressure. The exact mechanism by which probiotics lower blood pressure is not yet fully understood, but it is thought to be related to the production of certain substances, such as short-chain fatty acids, which can relax blood vessels and reduce blood pressure.
Probiotics have been shown to have anti-inflammatory properties, which can help reduce inflammation in the body, including in the heart and blood vessels. Chronic inflammation is known to contribute to the development of atherosclerosis (hardening and narrowing of the arteries), which can lead to heart disease. Probiotics can help reduce inflammation by regulating the immune system and reducing the production of pro-inflammatory molecules.
Several strains of probiotics have been found to have a beneficial effect on cholesterol levels, particularly on reducing LDL (bad) cholesterol. For example, Lactobacillus acidophilus and Bifidobacterium bifidum have been shown to significantly reduce LDL cholesterol levels in some studies. The mechanism by which probiotics lower cholesterol is not yet fully understood, but it is thought to be related to the production of certain substances, such as bile salts, which bind to cholesterol and prevent its absorption in the gut.
Regulating blood sugar:
Probiotics have been found to have a beneficial effect on blood sugar levels, particularly in people with type 2 diabetes. One study found that daily consumption of a probiotic drink for 6 weeks resulted in a significant reduction in fasting blood sugar levels in people with type 2 diabetes. The exact mechanism by which probiotics regulate blood sugar is not yet fully understood, but it is thought to be related to the production of certain substances, such as short-chain fatty acids, which can improve insulin sensitivity and reduce the absorption of glucose from the gut.
Probiotics may be a powerful tool for maintaining your overall health such as improving heart health. They may help lower blood pressure, reduce inflammation, lower cholesterol, and regulate blood sugar levels. Adding probiotic-rich foods to your diet or taking a probiotic supplement can be a simple and effective way to protect your heart. So, the next time you reach for a yogurt, remember that you are not only satisfying your hunger, but you’re also doing your heart a big favor!
