If candy and high-fructose, sugary desserts or salty chips seem to be a family favorite and you want to change that, just don't buy them. This is one hack that is easy to solve. Find a healthier substitute, and train the family to get used to loving that instead. Let those unhealthy treats be just that — for another kid's birthday party, during a movie night, or at a play date. Not purchasing them gives you the power and, let's face it, keeps the grocery bill down, too.
