Many people connect fibre mainly with gut health, yet its impact goes far beyond digestion. Cardiologist Dr Dmitry Yaranov explains that increasing fibre intake can meaningfully support the heart by lowering harmful LDL cholesterol, improving blood pressure stability, and reducing inflammation that contributes to cardiovascular strain. Fibre also slows sugar absorption, which helps prevent insulin spikes that place additional pressure on the heart over time. These combined effects can strengthen overall cardiovascular resilience in ways many people underestimate. Understanding how this simple nutrient works throughout the body may motivate you to make small, steady dietary changes.



Even modest increases in daily fibre can create long-lasting improvements in heart health and overall metabolic balance.





How fibre supports heart health beyond digestion



Most conversations about fibre focus on digestive comfort, regular bowel movements and maintaining a healthy gut. While these benefits are valuable, fibre plays an equally important role in protecting the heart. Dr Yaranov explains that fibre does not merely support the digestive tract. It also helps regulate the body’s metabolic responses, which directly affect cardiovascular wellbeing.



Soluble fibre slows the absorption of sugars in the bloodstream. This creates steadier insulin levels, reducing metabolic stress that can otherwise lead to high blood pressure, inflammation and strain on the heart. When insulin spikes are controlled, the heart is placed under less pressure, allowing it to function more efficiently.

Why increasing fibre intake reduces cholesterol-related risks



One of the most significant advantages of consuming more fibre is its ability to lower LDL cholesterol. LDL, often called the harmful cholesterol, contributes to the buildup of plaque in the arteries. Over time, this builds up nin arrows blood vessels and increases the risk of heart attacks and other cardiovascular complications.



Fibre binds to cholesterol particles in the digestive tract and helps carry them out of the body. This process naturally improves lipid profiles without relying on medication. Dr Yaranov notes that individuals who regularly consume adequate fibre often experience noticeable improvements in their cholesterol readings, even when no other lifestyle changes are made.







Role of fibre in blood pressure, weight, and inflammation



A diet rich in fibre supports stable blood pressure by improving blood vessel function and reducing inflammation. Persistent inflammation is a silent contributor to numerous cardiovascular diseases, and fibre helps counteract it by nurturing beneficial gut bacteria and encouraging smoother metabolic processes.



Higher fibre intake is also linked to better weight management. Foods naturally rich in fibre tend to be more filling and slower to digest, helping people maintain healthier eating habits without feeling deprived. Dr Yaranov highlights that individuals who reach their daily fibre targets typically report better weight control, steadier energy levels, and a reduced risk of metabolic disorders. These combined effects contribute to stronger long-term heart health.





Why meeting daily fibre requirements reduces heart disease risk



Research consistently shows that people who consume sufficient fibre every day generally experience lower rates of heart disease, heart attacks, and coronary artery problems. Dr Yaranov emphasises that these outcomes are not limited to high-risk individuals. Even those without existing heart conditions benefit from the protective effects of fibre. The simple act of eating more whole grains, fruits, vegetables, and legumes can lead to measurable improvements in cardiovascular function over time.





Precautions when using fibre supplements



Although fibre from natural food sources is ideal, many people rely on supplements to increase their intake. Dr Yaranov advises caution with this approach, particularly for individuals on heart medication. Fibre supplements can interfere with the body’s ability to absorb certain drugs, especially those prescribed for heart failure, high blood pressure and blood thinning.



To avoid this interaction, Dr Yaranov recommends taking fibre supplements separately from prescribed medicines. Allowing a gap between supplements and medication ensures that important heart drugs absorb properly and deliver their full therapeutic effect. Giving medication a clear and uninterrupted window helps maintain stable treatment outcomes.





Developing a routine that includes fibre-rich foods not only supports a healthier gut but also reduces strain on the heart, improves metabolic balance, and contributes to a lower risk of heart disease. A simple, daily commitment to eating more fibre-rich meals may be one of the most accessible and effective ways to protect long-term cardiovascular wellbeing.
