Skin wrinkling: can food make a difference?
- was a question asked by Purba et al. in 2001. They focussed on skin wrinkling in a sun-exposed site and investigated whether food intake was correlated with wrinkling in the 453 participants. Although it is only a correlation study (and correlation does not necessarily imply causation), the measure of skin wrinkling was objective- it was assessed using a cutaneous microtopographic method.
Perhaps unsurprisingly, a high intake of vegetables
and olive oil
appeared to be protective against cutaneous actinic damage - interestingly, they collectively explain as much as 20% of the variance. A high intake of meat
was associated with more wrinkling.
