Drinking green tea daily could reduce bad cholesterol and support heart health, according to new research. A low-cost habit with high-impact results.
A Simple Drink With Big Health Benefits
A daily cup of green tea—costing just 4p—could play a powerful role in reducing cholesterol and protecting heart health, according to new scientific findings. The evidence, drawn from extensive studies, highlights green tea’s rich catechin content as a natural ally against cardiovascular disease.
Cholesterol: A Silent Risk to Heart Health
Cholesterol is a fatty substance that, in high levels, can clog blood vessels and restrict blood flow. These blockages significantly increase the risk of heart attacks and strokes. While genetics and lifestyle contribute, diet remains one of the most influential factors in cholesterol management.
What the Research Shows
A landmark study published in the Journal of the American Dietetic Association in 2011 found that catechins in green tea significantly reduced total and LDL (“bad”) cholesterol levels. Similarly, a 2020 meta-analysis in Nutrition Journal reviewing data from over 3,300 participants confirmed these findings. Though green tea had little effect on HDL (“good”) cholesterol, it effectively lowered triglycerides—a known heart health marker.
Consistent Results Across Populations
The cholesterol-lowering effects were seen regardless of participants’ weight or baseline health. Still, researchers note that further studies with diverse populations and longer trial periods are needed to understand the full impact of green tea over time.
More Than Just Cholesterol Control
Beyond heart health, green tea’s catechins may offer additional benefits. According to Harvard nutrition expert Teresa Fung, regular green tea consumption could also help regulate blood sugar, lower cancer risks, and even prevent dental decay. For maximum effect, she recommends drinking three cups daily.
Affordable and Accessible
With 20-bag packs of green tea available at major UK retailers like Tesco for as little as 75p, the cost per cup comes in at under 4p—a small price to pay for a potentially life-saving habit. Experts still recommend consulting a GP for personal health advice, but adding green tea to a balanced diet could be a smart step toward better cardiovascular wellness.
