A cardiologist has highlighted avocados as one of the best foods people can eat to support heart health and reduce their risk of cardiovascular disease. Heart disease remains one of the leading causes of death in the UK, prompting growing interest in foods that can help protect the heart.
According to cardiologist Sarah Alexander, avocados stand out because they are packed with nutrients linked to lower cholesterol levels, healthier blood pressure and improved cardiovascular health. Research suggests people who eat at least two servings of avocado per week may be significantly less likely to develop heart disease compared with those who rarely consume the fruit.
Studies cited by nutrition experts found people who regularly ate avocados were 16% less likely to develop cardiovascular disease and 21% less likely to develop coronary heart disease. Replacing foods such as butter or margarine with avocado was also associated with a lower risk of heart-related conditions.
The fruit contains high levels of potassium, fibre, antioxidants and heart-healthy monounsaturated fats, all of which play an important role in cardiovascular health. Sarah Alexander said potassium is particularly beneficial because it helps counteract the blood pressure-raising effects of sodium. Half an avocado contains nearly 500mg of potassium, more than a typical banana.
Avocados are also rich in fibre, with half a fruit providing almost seven grams. Fibre has been linked to lower cholesterol levels and improved blood pressure control, while helping people maintain a healthy weight. Another benefit comes from plant sterols, naturally occurring compounds that help block cholesterol absorption in the gut.
Speaking to the Mirror, she said: “Plant sterols can lower cholesterol by preventing absorption of cholesterol, and lower cholesterol can reduce your risk of developing cardiovascular disease.” Health experts stress that no single food can prevent heart disease on its own. However, incorporating nutrient-rich foods such as avocados into a balanced diet, alongside regular exercise and avoiding smoking, can help support long-term heart health.
