Rocker Bryan Adams reckons being vegan has prevented his hair from going grey.
The Canadian star, 60, also credits following a plant-based diet for 30 years for keeping him trim.
He said: “I’d love to see a comparison photo of me if I hadn’t taken this path.
“My guess is I’d be a lot heavier and perhaps I’d have gone grey.
“Oddly at 60, neither have happened, and I can only attribute that to what I’ve been ingesting.”
The brown-haired eco-conscious singer has partnered with DHL to plant a tree for every ticket sold to his Shine A Light tour.
Dad-of-two Adams is also backing the Mirror’s Million Trees campaign.
*Bryan Adams Rocks! is on Radio 2 on Boxing Day at 8pm.
