It is an interesting topic and certainly common among many, as it is part of habits that are acquired over a long period of time. Personally I believe that they can be controlled but not eliminated, because a taste is necessary for those who work hard and everything cannot revolve around that. In Venezuela something curious is happening, sometimes it is cheaper to eat out than to prepare food at home, because the high cost of the products cause excessive spending.
