“One reason coffee is healthy is because it contains mildly toxic substances that activate an alarm-protein, called Nrf2, in our cells. When Nrf2 detects these mildly toxic plant substances in the coffee, it travels to the DNA in the cell nucleus, where it starts up the production of our own body antioxidant and detoxification proteins. Detoxification proteins are activated because the cells want to eliminate these mildly toxic substances as quickly as possible.”
