How the business of detoxing just got juicy For anyone not familiar with the juice cleansing ritual: Plenish's website describes cleansing as a "healthy form of routine maintenance" allowing your digestive system and liver the rest it needs in order to release accumulated toxins. At the same time, you will be flooding your system with organic, easy to digest, liquid nutrition filled with "living" enzymes and vitamins. American women have always led the way in the raw juice cleanse market. In 2007, BluePrint was founded in the USA by friends Zoe Sakoutis and Erica Huss. The 'original' cold-pressed fruit and vegetable juice company, they boasted a turnover of some £15m last year. In five short years they made it almost as easy to pick up a juice as a can of coke in parts of the USA. Last month they were purchased by Hain Celestial, a NASDAQ listed company, bringing a niche sector to the attention of the mainstream and confirming to the likes of Kara that "there is demand" for fresh products of this type. "Pasteurised juices today are almost like canned soup," chief executive of HAIN Celestial Irwin Mitchell recently said to analysts. Elsewhere, Radiance Cleanse was set up by two Brits; friends Clare Neill and Christina Agnew, in 2009. Christina told me she had an interest in nutrition from a young age. She never lost that interest and whilst working as a lawyer she also studied for a BSc in Nutritional Medicine. After several years she realised her path lay in nutrition - and decided to "swap the law books for a hydraulic juice press." Whilst working "too hard" for a private equity fund Clare was diagnosed with a stomach condition and only regained her health by radically changing her diet, "chucking all the chemicals out of her house" and going on her first juice cleanse retreat. After that retreat she became convinced of the power of juicing and nutrition for wellbeing and long term health - and Radiance was born. Now in its third year of trading, the company maintains consistent double digit year on year growth supported by their 80pc female client base. I spoke to Niccy Parry, a nutritional therapist and asked her whether cleanses are all they are touted to be or whether they were just another fad for the overly health conscious. She told me that for detox virgins, "a juice fast is not necessary the right way to go" or at least not for longer than 24 hours. However, she said that incorporating Plenish or Radiance's juices as part of a detox not only "assists the body in cleansing, but also nourishes the body with nutrients, shifting the pH to become more alkalinic." I know that an "alkali" body is a healthy body. And an increasingly health aware customer is a healthy prospect for Kara, Clare and Christina, who have been building their businesses just in time to catch the raw juice and detox sector going mainstream. Whether you chose raw fruit juice, vegetable juice or cashew milk, 'Go Green' now has a whole new meaning on the UK high street thanks to the likes of Radiance and Plenish.
