  • Michael Mosley explains how taste buds work. Each taste bud is made from a cluster of cells with hair like receptors at their tip which analyse the chemical composition of food and send signals about their findings to the brain. The tongue only detects five different taste groups: salt, bitter, sour, sweet and savoury (umami). Every human has around 8,000 taste buds on their tongue; however, these are concentrated over a smaller area in children, which means they often have a greater sensitivity to taste than adults. First broadcast on 'Inside the Human Body' on BBC One in May 2011.
