The science of how food impacts our health and environment

Veganism is having a moment. From ‘Veganuary’ promotions to whole lines of products in fast-food chains such as KFC and Greggs, there is a concerted effort to lure customers away from meat and dairy. But with the boom comes a deluge of quackery and misinformation.

In this episode Marco Springmann, a public health researcher at Oxford University, separates fact from fiction. He tells Anushka Asthana what the data says about the health and environmental impact of veganism and cutting out meat and other animal products. Here is a direct audio link.

Fighting illness with a healthy gut

The connection between what we eat and our physical and mental health has never been more evident, and yet, most people, including doctors, do not focus on this fundamental connection.  Dr. Will Bulsiewicz’s new book Fiber Fueled, written before the pandemic and released in May, is perfectly timed.  It’s also incredibly accessible and easy to read.  Will is that rare powerful combo:  a genius in his field and an excellent communicator.  His recent podcast discussion with Simon Hill is worth listening to.
