Well this was theoretical part of minerals . Coming to everyday life , here are some of the notes which may help you-
Note :
1. If you are having vomiting or diarrhoea you loose fluid along with minerals causing electrolyte imbalance. That's why you take ORS ( oral re hydrate solution) which replenishes lost minerals .If you notice the composition there would be sodium,chloride,potassium in it.
2. If you have both vomiting and diarrhoea,you need to go to doctor immediately as this may cause severe imbalance resulting in complications. 
3. When you are in outdoor sports for long time replenish your self with natural fluids containing salt and sugar.


Minerals are less talked upon when it comes to diet which is an essential component regulating many functions. Less or more of minerals too causes problems . Have a balanced  diet and lead a happy healthy life.
