Pigs' trotters are good for your skin

...according to this article in the Telegraph.

Apparently there is a new restaurant in New York, Hakata Tonton, specialising in 'collagen cuisine'. Pigs' trotters are high in collagen, the protein responsible for skin strength and elasticity. As you get older its degradation leads to wrinkles. So if you eat pigs' trotters, so the argument goes, you'll replace the broken-down collagen and have lovely younger-looking skin.

I'm no nutritionist, but surely the problem with this is that when we eat food we digest it and turn it into something else?

If anyone wants to test it, Hugh Fearnley-Whittingstall's brilliant River Cottage Meat Book includes at least four recipes for pigs' trotters. I will be looking carefully at his skin next time he comes on tv to see if he has any wrinkles.
