New research highlights a surprising and affordable way to potentially improve cardiovascular health: coriander seeds. This common spice, costing as little as 6p per serving, may assist in lowering cholesterol levels and reducing blood pressure, according to scientific studies. These effects could significantly decrease the likelihood of developing severe conditions such as heart disease, heart attacks, and strokes.
Scientific Evidence Supporting Coriander's Benefits
A study published in the Journal of Environmental Biology in 2008 investigated the impact of coriander seeds on laboratory rats. The findings were promising, showing that rodents fed these seeds experienced a reduction in "bad" cholesterol, specifically low-density lipoprotein (LDL), while their levels of "good" cholesterol, or high-density lipoprotein (HDL), increased. The research described this as a "remarkable hypolipidemic action," indicating its potential for lipid management in humans.
Additional Research on Blood Pressure
Further evidence comes from a 2009 study in the Journal of Ethnopharmacology, which found that coriander seeds, also referred to as the fruit of the herb, could effectively lower blood pressure, or hypertension. The study suggested that these effects might be mediated through mechanisms involving cholinergic activity and calcium antagonism, with diuretic properties adding to its value in managing high blood pressure.
Understanding Cholesterol Levels
For context, normal total cholesterol in the blood should be five or less millimoles per litre (mmol/l). More specifically, HDL levels should be one or more mmol/l, while LDL should measure four or less mmol/l. To determine if cholesterol levels are elevated, individuals should consult their GP for a blood test. Similarly, monitoring blood pressure can be done using home testing kits or by requesting readings from a pharmacist or doctor.
Incorporating Coriander into Your Diet
Coriander seeds are versatile and can be used whole or ground into a powder in various dishes, such as curries and stews. The plant itself is also popular as a fresh herb. At the time of reporting, ground coriander is available from major retailers like Sainsbury’s and Tesco, with a 36g pack costing £1.10, equating to just 6p per 6g serving. This makes it an accessible and cost-effective addition to daily meals for those looking to support their heart health naturally.
