Sometimes your body is trying to tell you something - such as that it is suffering from a vitamin shortage, that it's not getting enough sleep and that it's really sick and tired of hamburgers and chips.
We tend to notice the big things, such as migraines and terrible leg cramps or constant diarrhoea. But little things easily pass us by.
It isn't always easy to know how to interpret these signals that your body is giving you.
In fact, sometimes you could be struggling with something for years without knowing what it is your body is trying to tell you.
These are often not life-threatening things, but mildly irritating and constant things, such as a few mouth ulcers, or brittle nails or a greasy skin.
What are these signs your body is giving you, and what does it need you to eat to rectify the situation?
