Word of the Day: Xanthinophile
A xanthine is one of a small group of alkaloid molecules which are naturally formed in the body. However, the methylxanthines are stimulants that block sleep signals and thus keep you alert; they include theobromine (in chocolate, cacao, cocoa), theophylline (in dark chocolate, tea), and caffeine (in coffee, tea). They alleviate asthma and, as a huge number of modern scientific studies show, are boosters for almost all aspects of human health and well-being (the old word was 'wealth', but that's been corrupted).
Xanthinophiles are therefore people who love coffee, tea and/or chocolate and other preparations that are chemically related to these.
