Why it is bad to add sand to soil?

On a figure (which now I can't find anymore), I saw that more sand will help to keep more water in soil (there is, IIRC, a sweet point of around 30% of sand; much more sand will make water flow away). Really I add sand only when planting trees, on sub-soil, and a little sand on seedlings, not to have mould. So, is it bad to add sand? Why?
