Aging gracefully requires taking out the trash

This is an interesting study that lends support to some age-old concepts from the natural health field that have been described in various ways, such as clearing excess (chinese medicine), cleansing or detoxifying (naturopathy), and removing ama (ayurveda). It shows that calorie restriction promotes the removal of pathological accumulations from the body and may suggest (IMO) that occasional modified fasting is also beneficial.
