Recent research found wrinkle width and severity to be reduced in postmenopausal women who snacked on almonds on a daily basis. Almonds are already associated with an array of health benefits due to the fact they're full of vitamins, minerals, protein and fibre.
A pilot study was undertaken to investigate what sort of impact eating almonds had on wrinkles, it looked at 28 healthy postmenopausal women with a skin type categorised by the Fitzpatrick scale as type 1 or 2. This is a skin type that has a tendency to burn. The women were divided into two groups, one group consumed 2 oz of almonds per day while the other ate 2 oz of nut free snacks.
The skin of each participant was assessed at the start of the study and then at 4 weeks, 8 weeks, 12 weeks and 16 weeks. Wrinkles were measured using high resolution facial imaging and validated using 3D facial modeling and measurement. This allowed for a severity score to be given which involves a calculation of the depth and length of a wrinkle.
Wrinkle width and severity decreased
The results showed that by 16 weeks wrinkle width had decreased by 10% and winkle severity had decreased by 9%.
Almonds are a rich source of antioxidants, which as we know, protect us from the damage inflicted on the body by oxidative stress. The inflammation associated with oxidative damage is one of the key factors in accelerated aging. It is therefore important to point out that the effects seen in the study may not be unique to almonds and instead to attributed to the anti-inflammatory effects of vitamin E, fatty acids and polyphenols.
The small size of the study we're looking at here is a limitation but the results are promising none-the-less and it has paved the way to future larger studies with expanded population groups and additional evaluations for signs of skin aging. The researchers concluded by saying:
"Food as a means of promoting skin health - the "health from the inside out" idea - is of growing interest to those looking for healthy ageing. It's also a growing area of scientific research. Almonds are a rich source of antioxidant vitamin E and deliver essential fatty acids and polyphenols. They're a smart choice for overall good nutrition. And, as seen in this study, almonds may hold promise as a food to include as part of a healthy aging diet, especially for post-menopausal women."
