Nourish skin from within

We all know the saying "an apple a day keeps the dentist away", but it's not just Granny Smiths that keep our health and appearance in tip top shape.

Avocados can keep more than our teeth pearly white. They work a treat on our skin and hair, and leave our bodies fighting fit with the types of fats we need.

Sydney-based nutritionist Zoe Bingley-Pullin, from Nutritional Edge, says avocados are full of monounsaturated fats.

"There's a lipid layer around every single cell in the body and your body needs a constant supply of good fat, otherwise the body goes and produces it itself."

She says foods such as nutrient-dense avocados help the overall health of our skin.

About 10 per cent of an average 100g avocado is made up of these good monounsaturated fats.

An avocado has "no cholesterol in it, so all of these fats really are good fats", she says.

"It's got no trans fats, which are obviously the real nasties, and it's got a tiny amount of saturated, but the body does actually need a small amount of saturated fats for the diet anyway."

Queensland-based company Australian Avocados says the effective combination of monounsaturated fat and antioxidants helps to nourish the skin from within and reduce stress.

The B vitamins in avocados, such as folic acid, help limit the effects of stress on our bodies, internally and externally, adds Bingley-Pullin.
