Hormesis - a small amount of 'toxin' eg exercise or Intermittent Fasting can help

Hormesis (wikipedia) involves a biphasic response in which a small amount of a toxin has a beneficial effect whilst increasing quantities are toxic.

An example of a hormetic product is selenium which is a micronutrient and improves health at low doses but is toxic at high doses. Plants and vegetables (5 a day) and Exercise have a hormetic effect too.
A very low dose of a chemical agent may trigger from an organism the opposite response to a very high dose.
