Do certain foods make us 'clean'?

Scientist Dr Giles Yeo has made a programme for ÃÛÑ¿´«Ã½ Two's Horizon where he investigates the social media sensation of "clean eating". He goes on a journey to the US, where he sees the extreme side of the lifestyle at a Californian ranch where cancer patients are being treated with alkaline food.
Dr Yeo, Rose Lloyd Owen, who runs a healthy eating food and yoga festival, and Carrie Armstrong, who says she was obsessed by "clean eating," discuss whether the food we eat really cleans our bodies, and makes us feel well.
