Bad breath is a huge social discomfort, so most of us would probably be very happy to find that our breath smelt like grapefruit. After all, what’s wrong with smelling like a sweet but healthy fruit? However, there’s definitely a reason for concern if you haven’t eaten any grapefruit lately. This sweet smell on the breath could actually be a sign of diabetes. If left unchecked, this can cause a myriad of health problems, including death. We normally burn energy from insulin, but when there is none left, the body turns to fat, which causes this sweeter smell to be emitted. Ketones are released during the process, and they hold the fruity smell. Your partner is more likely to notice this than you are, so make it clear to them that you won’t be offended if they point out a strange smell on your breath on more than on occasion.
A very interesting study was recently carried out which looked at sense of smell, and how it can give us a timeline for death. More than 3,000 participants were asked to smell 5 things, which were strongly scented with peppermint, fish, oranges, roses, and leather. They then monitored the participants over the next 5 years. 39% of those who could not smell anything were dead within 5 years, and 19% of those who only managed to identify one or two smells were dead. For those who passed the test easily, only 10% had died. So there you have it– if your sense of smell starts to disappear for no reason, then you could be within 5 years of death.
