Recommended by Heywood Hill Reader Sir Crispin Tickell:
'It is well known that we are what we eat, and what we are is essentially the bugs of all shapes and sizes inside us. How we nourish and support the bugs is the critical issue of diet, and here we learn about it in all its forms. Perhaps the central theme is that every individual is different, and whether we wish to be fat or thin demands understanding beyond the constant and often contradictory advice we receive from outside. The message is: look after your microbial garden.'
