Alongside the research on tea, it’s interesting to look at research on its greatest rival, coffee. Or maybe not … Aside, perhaps, from environmental issues, to tackle which large-scale recycling programmes are being rolled-out (especially by Nespresso), aluminium in coffee pods is not, at the moment, a cause for concern when it comes to the health of their millions of consumers. However, there is something in the bean roasting process that might raise legitimate worries.
Furan is categorized as a potential carcinogen in high doses. This molecule is found in all high-temperature food-preparation processes: cereals, baby food, toast … the molecules contained in coffee pods, assuming moderate consumption of this beverage, have not been considered by science to be harmful to the liver. Hopefully this will reassure the fortunate owners of “Nespresso” machines, languorously sipping their drinks like George Clooney.
