Health experts are highlighting a simple and affordable dietary addition that could significantly benefit heart health: the humble aubergine. Priced at just 95p each at Tesco at the time of publication, this common fruit is being recommended for its potential to help lower elevated cholesterol levels in as little as four weeks.
The Science Behind Aubergine and Cholesterol
Elevated cholesterol occurs when there is an excess of a fatty substance circulating in the bloodstream. While not an immediate danger, sustained high levels can cause arteries to harden and narrow, dramatically increasing the risk of heart attacks and strokes. Diet is a cornerstone of managing cholesterol, and while some foods high in saturated fat can raise levels, others, like aubergine, can have the opposite effect.
Cheryl Lythgoe, Matron at Benenden Health, explained to Express.co.uk that aubergines are a versatile and tasty addition to many dishes. Their key benefit lies in being a great source of fibre and containing an antioxidant that may help reduce 'bad' low-density lipoprotein (LDL) cholesterol. The fibre works by blocking the absorption of some cholesterol from the intestines into the blood.
Research Shows Promising Results
This guidance is supported by research published in the journal of the Brazilian Society of Cardiology. The study involved rabbits fed a cholesterol-rich diet. One group was also given 10ml of aubergine juice daily for the final two weeks of the four-week study.
The results were striking. Study authors found that after four weeks, the rabbits receiving the aubergine juice had significantly lower weight, plasma cholesterol, LDL, triglyceride, and aortic cholesterol content compared to the control group. They concluded that the juice "significantly reduced weight, plasma cholesterol levels [and] aortic cholesterol content."
How to Manage Your Cholesterol Levels
Medical guidance states that a safe total cholesterol level is typically five millimoles per litre (mmol/l) or below. Specifically, high-density lipoprotein (HDL or 'good' cholesterol) should be one mmol/l or higher, while LDL should be four mmol/l or lower. A simple blood test arranged by your GP can determine if your levels are raised.
Cheryl Lythgoe emphasises a holistic approach to heart health. She advises eating a balanced diet rich in fruit, vegetables, lean meat, and wholegrains, while being low in saturated and trans fats. She also stresses the importance of regular activity, endorsing the British Heart Foundation's recommendation of at least 150 minutes per week, such as brisk walking or cycling. This can help raise 'good' HDL cholesterol, lower blood pressure, and maintain a healthy weight.
Other factors linked to raised cholesterol include smoking, excessive alcohol consumption, and insufficient physical activity. While adding aubergine to your diet may offer benefits, anyone concerned about their cholesterol readings should always consult their doctor for personalised advice.
