It’s been a while since your last meal and you start to get irrationally irritable – we’ve all been there. Some people call it being “hangry.” But what’s the science behind that frustration, and is there anything – other than eating all the time – that you can do to stave it off?
The word first came to prominence in the 1990s. As you might suspect, it’s an amalgamation of “hungry” and “angry.” And, in a roundabout way, there’s an amalgamation of different processes in your body that cause that downturn in your mood.
One of the main culprits is glucose – or rather, it’s a lack of glucose. When you’ve eaten a meal, your body starts to break down the proteins, carbohydrates and fats into three different things: amino acids, free fatty acids and simple sugars.
