take what he/she says with a pinch of salt
If someone advises you to 'take (something) with a pinch of salt', they are telling you not to rush to believe whatever you have been told. This is often said when a person regularly lies or makes things up that are not true, but it can also be used when talking about the promises of politicians and institutions that people generally do not trust: "The government might promise a lot of things to get elected, but you should take their promises with a pinch of salt."
