My dentist has advised me not to brush after a sugary meal or drink for at least an hour, otherwise you are effectively brushing the sugar into your teeth. Perhaps this also applies (but with a lesser timeframe) for meals that aren't so sugary.

It's more that your enamel is weakened temporarily by acids (which get produced by bacteria in your mouth as a side effect of their consuming the sugar). It is true that you shouldn't brush immediately after a meal -- waiting 30 minutes to an hour is a good practice.
This is doubly so if the meal is sugary. By not brushing afterward, you're just letting bacteria process all that sugar and produce plaque and acid.
