Give your skin an age-defying boost with these naturally anti-ageing foods.

We, along with A-list beautician and Heaven skincare founder Deborah Mitchell, have picked some of the best:

Nuts

Nuts are a great source of healthy fats, promoting smooth skin and wrinkle protection.

Deborah Mitchell swears by Macadamia nuts, which contain all essential amino acids, the building blocks to great skin.

Top tip: Swap you sweet or salty snacks for nuts

Berries

Rich in anti-oxidants such as vitamin C and carotenes, the darker or more vivid the berry, the richer the anti-oxidant content.

Concentrate on blueberries, blackberries, strawberries, raspberries and cranberries as they are packed with anti-ageing nutrients and phyto-nutrients that protect the skin from the damaging effects of sun exposure and free radicals.

Top tip: Sprinkle them onto wholegrain breakfast cereal or porridge or mix with yoghurt for a healthy start to the day.

Sweet potato

Beta-carotene gives sweet potato its bright orange colour and when consumed it is converted into vitamin A, an anti-oxidant that helps protect the skin, eyes and bones. Look out for butternut squash, mango, papaya, carrots and pumpkin too.

Top tip: The beta-carotene is best released after cooking, making sweet potatoes great for baking, mashing and soup making.

Flax seeds

The minerals found in flax seeds help to reduce the appearance of wrinkles by increasing the bond strength in the collagen layers of the skin.

Top tip: Toast them with a healthy nut mix for salads and other toppings.

Red wine

Deborah comments: "Red wine is full of anti-oxidants and the purple skin of the grapes helps to detoxify the skin. They're full of naturals phenols."

Top tip: Everything in moderation!

Dark chocolate

We know it’s good for us, but how does it work? A nutrient found in it can increase blood flow to the skin, boosting oxygen and nutrient supply; it’s the sugar and fat content in low quality chocolate that can make blood flow sluggish and congest the pores.

Deborah adds: "Dark chocolate can boost metabolism and contains magnesium."

Top tip: Look out for chocolate with a high cocoa content.

Beetroot

Beetroot tops are rich in folate, magnesium and zinc, which acts as anti-oxidants and fight the ageing effects of DNA damage to our skin and other cells in the body. They also contain essential vitamins and minerals for healthy hair and nails.

Top tip: Try cooking cakes or brownies with beetroot.
