"Forget low-energy lightbulbs and solar-powered homes – curry spices could hold the key to reducing greenhouse gas emissions.
Research carried out at Newcastle Univ has found that coriander and turmeric – spices traditionally used to flavour curries –
can reduce the amount of methane produced by bacteria in a sheep’s stomach by up to 40pc.
Working a bit like an antibiotic, the spices were found to kill the methane-producing ‘bad’ bacteria
in the animal’s gut while allowing the ‘good’ bacteria to flourish...
Mehedi explained: “Spices have long been used safely by humans to kill bacteria and treat a variety of ailments
– coriander seeds, for example, are often prescribed for stomach complaints
while turmeric and cloves are strong antiseptics"
