What is the grammar rule for this sentence

[english_learn]

Please look at the sentences below:


Food manufacturers are using a loophole in trademark law to dupe consumers into thinking products high in fat or sugar are healthy, a study has found



My understanding on this after TO "ing" format should not be used. In the above sentence "into thinking " is wrong I guess. It should be into think? Am i right?

if I am wrong tell me the grammar rule?
Thanks

No, it is quite correct as written. 'Into' is a preposition, and therefore requires here a gerund as object.

quick question if I may: looking back to the first post question, is it possible to replace the word "thinking" gerund into a normal verb? I'm sure "think" would be wrong, but maybe another word that i can't think of? thanks

The gerund is the normal verb-form here. No other form is possible.

You could change the verb into something like believing/feeling, but it would still be a gerund.
