What do food cravings actually mean?
A journalist at the Daily Mail is looking for comment from an expert on what food cravings mean, such as how craving chocolate can mean you need magnesium - so it's best to eat nuts.
She's looking for as many examples of cravings as possible and detailed explanations for the particular cravings.
Please give me two examples maximum.
