No one needs to detox. Unless you've been poisoned, you already have a superefficient system for filtering out most of the harmful substances you eat. It's made up of two toxin-bashing organs: the liver and the kidneys. 

While our kidneys filter our blood and remove any waste from our diet, our livers process medications and detoxify any chemicals we ingest. Paired together, these organs make our bodies natural cleansing powerhouses.
