Dark blue and black foods (and some dark red foods) contain a family of polyphenols called Anthocyanins.
Not only are anthocyanins know to be powerful antioxidants to prevent ‘cellular rusting’ instigated ageing BUT preliminary studies are showing anthocyanins to increase the levels of collagen, elastin and Hyaluronic acid in skin .
Anthocyanins have also proven themselves to be potent anti-inflammatory antioxidants , protecting against oxidative damage as well as UV eye damage . Anthocyanins also seem to protect against age-related cognitive decline (along with other plant based foods)  and be protective against skin-cell oxidation and UV-instigated skin damage 
WHICH BEAUTY FOODS CONTAIN ANTHOCYANINS?
Encourage your clients to eat 1-2 servings DAILY of blue / purple foods for them to benefit from these potent Anthocyanins.
