The skin is a real nutritional powerhouse. Just one fist-sized potato skin provides half your daily recommended intake of soluble fibre, potassium, iron, phosphorus zinc and vitamin C.

Bake whole in their jackets, boil and mash with the skin on or slice into large chunks, toss in a little olive oil and bake for potato wedges.

Potatoes are also good for hair — getting rid of those greys the natural way.
Boil potato peels in water for 30 minutes and cool. Use this water as an after-shampoo rinse and it will gradually darken grey hair, without the need for harsh chemicals.
