What's the difference between IEquatable and just overriding Object.Equals() ?

I want my Food class to be able to test whenever it is equal to another class. I will later use it against a List, and I want to use its List.Contains() method. Should I implement IEquatable or just override Object.Equals()? From MSDN:

This method determines equality by using the default equality comparer, as defined by the object's implementation of the IEquatable.Equals method for T (the type of values in the list).

So my next question is: which functions/classes of the .NET framework make use of Object.Equals()? Should I use it in the first place?

Thanks
