About this course

Natural therapists have a long history of advising their patients to reduce or eliminate caffeinated beverages, widely regarded as being toxic to the liver. Over the last decade or so there has been a surge in research investigations into the health effects of consuming coffee.

Clinical and epidemiological studies have revealed that coffee drinkers suffer less from liver diseases compared to non-coffee drinkers, while also tending to live longer. In this presentation we will delve deeply into the phytochemistry of coffee, with a particular focus on caffeine and polyphenols.

We will look into the potential adverse effects of these beverages, including caffeine addiction, and review recent research into their effects on human health, including cardiovascular health, diabetes and other chronic illnesses.
