Good new for curry fans – tucking into a spicy dish could be the key to a healthy heart.
Researchers found that the compounds that give cayennes, jalapenos and other chilli peppers their heat can lower high blood pressure and reduce blood cholesterol.
They said the chillies have great potential in protecting against heart disease, which is the number one cause of death in the developed world.
Hot stuff: Chillis extract their revenge through their fiery seeds but could be doing us good by encouraging blood flow
The study, from the Chinese University of Hong Kong, focused on a family of substances known as 'capsaicinoids' – the part of the chilli that gives them their 'kick.'
Study author Dr Zhen-Yu Chen said: 'Our research has reinforced and
expanded knowledge about how these substances in chilies work in
improving heart health.
'We now have a clearer and more detailed portrait of their
innermost effects on genes and other mechanisms that influence
cholesterol and the health of blood vessels. It is among the first
research to provide that information.'
In the study they gave two groups of hamsters high-cholesterol
diets, before giving one group food with varying amounts of capsaicinoids while giving the other control group food with no
capsaicinoids. The scientists then analysed the effects.
WHY ARE CHILLIS SPICY
Ever wondered why chilli peppers are so mind-blowingly hot It's all down to their ultra-effective defense system developed in the ongoing war between plants and animals.
When humans bite down on chillis they crush the seeds the plants want to spread with their molar teeth. The peppers extract their revenge by releasing a mouth-burning mix of chemicals called capsinoids.
Birds swallow the seeds whole and eventually pass them out the other end away from the original plant. They are therefore rewarded with the flesh of the chilli and left unscathed by the encounter.
They found the spicy substances lowered levels of 'bad' cholesterol by reducing accumulation of cholesterol in the body and increasing its breakdown and excretion.
They also blocked the action of a gene that makes arteries contract, restricting the flow of blood to the heart and other organs. By blocking it, the muscles relaxed and widened allowing more blood to flow.
'We concluded that capsaicinoids were beneficial in improving a range of factors related to heart and blood vessel health,' said Dr Chen.
'But we certainly do not recommend that people start consuming chilies to an excess. A good diet is a matter of balance. And remember, chilies are no substitute for the prescription medications proven to be beneficial. They may be a nice supplement, however, for people who find the hot flavour pleasant.'
