As I dietitian, I’m frequently asked whether cleanses are safe. There seems to be a deep fascination with cleanses out there—they carry a promise of pushing a reset button and purging your body of all those “toxins” that supposedly are building up. Cleanses usually take one of two turns: juice cleanses (replacing all solid foods with freshly pressed organic juices) or water cleanses (essentially fasting and just drinking water, and maybe adding a dash of lemon juice, cayenne and maple syrup a la the Master Cleanse).
But does your body need a break from digesting food in order to cleanse itself more efficiently? And are cleanses safe?
