Dark Chocolate Declared a Potent Medicine for Heart Disease Prevention
In a surprising revelation, dark chocolate has been hailed as "one of the best medicines around" for maintaining a healthy heart. Medical herbalist Simon Mills made this bold claim during an appearance on The Diary of a CEO podcast with Steven Bartlett, championing the benefits of this everyday cupboard staple for cardiovascular and cognitive wellbeing.
Expert Endorsement and Recommended Dosage
Mills declared dark chocolate to be "a medicine, end of," informing listeners that consuming between 50g and 100g daily could prove invaluable for health. He emphasized that this recommendation applies specifically to dark chocolate containing a minimum of 75% cocoa solids, which provides the medicinal benefits without excessive sweetness.
"I'm saying to many of my patients, take 50g a day, it's a medicine," Mills stated, cautioning that this doesn't include processed hot chocolate mixes but rather genuine dark chocolate with high cocoa content.
The Science Behind Chocolate's Health Benefits
The British Heart Foundation notes that cocoa contains high levels of flavanols – naturally occurring plant substances that help blood vessels relax and enhance blood flow. Harvard's T. H. Chan School of Public Health highlights that these flavanols have been associated with improved endothelial function, crucial for controlling blood pressure levels.
Research featured in the American Heart Association's journal Circulation has indicated a connection between increased chocolate consumption and diminished heart disease risk, though this doesn't establish definitive causality. Meanwhile, an analysis published in Heart by BMJ found that sensible chocolate eating was linked to decreased likelihood of cardiometabolic conditions, particularly strokes.
Official Guidelines and Additional Benefits
The European Food Safety Authority reports that consuming 200mg of cocoa flavanols daily can assist in maintaining normal blood vessel elasticity, supporting healthy blood circulation. Dark chocolate also includes stimulants like theobromine and modest quantities of caffeine, which could contribute to its mood-boosting properties according to the Cleveland Clinic.
Important Caveats and Moderation Warnings
Despite these promising findings, health authorities emphasize that chocolate should only be enjoyed as part of a balanced diet. The NHS stresses the importance of keeping portions sensible due to chocolate's considerable calorie content and saturated fat levels.
The British Dietetic Association maintains that safeguarding heart health should centre on an overall balanced diet abundant in fruit, vegetables, wholegrains and healthy fats, combined with regular exercise.
This perspective is particularly important given that cardiovascular disease remains the world's biggest killer according to the World Health Organisation, accounting for approximately 20.5 million deaths annually. The interview featuring Mills' chocolate recommendations was first aired in 2025, bringing renewed attention to the potential health benefits of this beloved treat when consumed responsibly.
