Heart disease is the second leading cause of death in the UK, after dementia and Alzheimer's disease. Many people seek ways to keep their hearts healthy, and diet plays a crucial role. Reducing foods high in fat, salt, and sugar is essential, but certain foods can actively help minimise cardiac risks.
Fruits offer a wide range of health benefits, and one fruit in particular may protect against heart disease—though it is often mistaken for a vegetable. US cardiologist Sarah Alexander has identified avocados as the top fruit for heart health, according to Surrey Live.
Why Avocados Are Good for the Heart
Avocados are rich in healthy fats, fibre, vitamins, minerals, and antioxidants. Research shows they can help lower cholesterol and blood pressure. A study cited by EatingWell found that people who ate at least two servings of avocado per week were 16% less likely to develop cardiovascular disease and 21% less likely to have coronary heart disease than non-consumers. Replacing just half a serving of butter or margarine with avocado was linked to a 16 to 22% lower risk of cardiovascular disease.
Key Nutrients in Avocados
- Potassium: Half an avocado provides nearly 500 mg of potassium, more than a banana. Potassium counteracts the blood pressure-raising effects of sodium.
- Antioxidants: Vitamin E and carotenoids reduce cholesterol and protect blood vessels.
- Monounsaturated Fat: Avocados are high in beneficial fats that help lower cholesterol.
- Fibre: Half an avocado contains nearly 7 g of fibre—a quarter of the daily recommended amount. Fibre helps reduce cholesterol and maintain healthy blood pressure.
- Plant Sterols: Avocados have more plant sterols than most fruits. These act as barriers to cholesterol absorption in the gut. Some research suggests plant sterols can reduce cholesterol levels by up to 10%. Dr. Alexander explains: "Plant sterols can lower cholesterol by preventing absorption of cholesterol, and lower cholesterol can reduce your risk of developing cardiovascular disease."
