Beauty foods: fact or fiction?
Only a handful of foods, drinks and supplements that claim to arrest premature ageing of the skin are supported by sound clinical data, experts have claimed.
The market for oral beauty supplements alone is set to top the $1.5bn barrier by 2010, and was growing at 9% a year, said botanicals expert Dr Joerg Gruenwald at the Vitafoods International conference.
However, while some were backed by serious human studies, others were making claims on the basis of "telephone interviews with 25 women, or worse, nothing at all". Still more referred to unpublished data and it was not possible to check their veracity, he said.
Controlled clinical trials with properly characterised food components were urgently required to boost the credibility of the sector, added Dr Marie Bejot, founder of French beauty supplements firm Oenobiol.
However, recent human studies had provided compelling evidence of the skin-boosting properties of omega-3 fatty acids, lutein and zeaxanthin, she said.
