Nutrition and

mental health

Strange as it may sound, the

bacteria that live in our guts have

a crucial influence on our mental

health. And since what we eat

controls the balance of these

microbes, the right dietary

choices could potentially boost

our mood and reduce anxiety.

In this online talk, microbiome

expert Ted Dinan explains how

this happens and doles out

some practical advice on eating

yourself happy. Join us on

27 January from 6pm GMT

(1pm EST).

Brain power

lives are imperative for keeping

our brains in good shape. Join

us on 3 February from 6pm

GMT (1pm EST). Tickets to

these events and many more

soak up more of the greenhouse

gas from the air.
