# How does salt push out the water from vegetables, meat, etc.?

Where can I find out, how does this process work? Have you noticed, that when you salt mushrooms, eggplant... or add sugar to lemon - some "juice" comes out.

Any explanations? Or maybe name that reaction?

As you probably know, water is a solvent. It can dissolve (some) solids so that no solid remains, only liquid. This usually has some effect on the solute (water in this case). Lets say you have two glasses of water - one of which has some salt dissolved in it. Nature would very much prefer if they were at the same concentration of salt. Nature wishes for 2 glasses of water with $\frac{some}{2}$ salt in each.
