Best quotes from This Book Could Save Your Life

“There is a multitude of reasons why processed food is so laden with salt. As well as prolonging shelf life, it makes cheap ingredients taste better and masks the bitter flavours that often result from industrial cooking processes. It can be injected into meat to make it hold more water, thus allowing water to be sold for the price of meat. It improves the appearance, texture and even the smell of the final products. And it makes you thirsty, boosting sales of drinks.”
“Observational studies are the most common type, but are haunted by methodological gremlins. Monitoring what people eat is time-consuming so most studies rely on self-reporting, often in the form of a food diary. Unsurprisingly, these are highly unreliable.”
“If you want to lose weight, the world is your oyster. Or maybe oysters are your world. According to any number of websites dishing out dietary advice, eating oysters is a great way of shedding the pounds.”
