When your hand reaches for a packet of chips, should you refrain and deny yourself the pleasure, or can you still eat a couple more? When going to the beach, how much sunscreen should you apply to your skin and how does SPF work? Is coffee good or bad? The book Ingredients, written by chemist and science popularizer George Zeidan, examines the variety of chemicals that end up in the human body in different ways. Is it true that processed foods are truly poison, and how do they contribute to obesity and other diseases? Why do we get sunburned and what are the consequences of excessive sunbathing? What happens when chemicals from foods and the environment come into contact with chemicals from our bodies? You'll learn why processed foods exist in the first place, and then work with the author to learn about the chemicals you're exposed to every day.
