Making your skin younger is easier with antioxidant-rich foods
A research was conducted to see if eating foods that are high in antioxidants can protect against premature skin ageing.
The research was done on individuals who are exposed to sun damage and with moderate to high UV exposure.
777 Australian adults from both genders with a mean age of 39 years participated in this research.
Their estimated total dietary antioxidant was estimated.
Moreover, the participants’ photoaging severity was looked into using microtopography over 15-year follow up, in three-time points.
Initially, 42% of the population has had severe photoaging
(grades ranging to 5 or 6).
Obviously, the number increases to 51% and 89% in 1996 and 2007, respectively.
Individuals with high photoaging grades had the following characteristics, which are:
- Older
- More likely to be male,
- Was born in Australia or New Zealand
- Fair skin that always burned
- Outdoor occupations
- Clinical photoaging around the
neck - ≥1 actinic keratosis
Participants whose diets consisted of fruits, lower intakes
of red meat, oily fish, soft drinks, tea, unrefined cereals and vegetables, as well as a greater amount of wine consumed than beer had a greater antioxidant capacity and they tended to be female, not currently smoking, older, regular consumers of dietary supplements and users of sunscreen, among others.
The levels of photoaging were not associated with body mass
index, leisure-time sun exposure, smoking status, sunscreen use prior to trial, and trial treatment allocation.
The researchers also stated that consumption of foods with
high vs low antioxidant capacity reduced photoaging by 10 per cent over 15 years among adults aged >45 years on an ordinal logistic regression analysis. Antioxidants from foods may mitigate the effects of sun exposure on skin ageing among healthy men and women aged >45 years.
