You can transform your skin just by eating the right foods

‘Eating a good, wholesome, nutrient-rich diet is paramount to promoting good health and radiant, youthful-looking skin.’

Cameron Diaz ditched the fast food for a healthy diet to clear up her acne.

Chamomile tea’s calming, hydrating properties make it great for skin.

Pomegranates have vitamin C that boosts the collagen in the skin.

Less is not only more when it comes to beautifying externally, the same maxim works internally, too – at least with the humble Brazil nut.

“You only need two or three a day to get high levels of selenium, which helps the body generate its own antioxidant, glutathione,” Carter explains. “Brazil nuts also have plenty of zinc, which is good for general skin health as well as for healing wounds.”

BROTH AND GELATIN

The vegetarians among us, myself included, are making life more difficult for our skin, according to Koullouros. “Beef gelatin is rich in collagen, which supplies amino acids, glycine and proline, all of which are important for healthy-looking skin. Bone stock broths are also rich in collagen. I drink broths every day.”

So does Alwill. “Broth is a fancy way of saying stock, and chicken soup has long been regarded as a remedy for so many ailments,” she explains.

“But I love it for skin because the slow-cooking of the chicken bones releases the collagen into the water. This collagen increases the stores in our body, feeding it to the skin cells and giving skin that gorgeous lift we all yearn for.”

Which explains why people inject the stuff. But yo, try eating it instead!

BERRIES AND POMEGRANATE

Both are really high in an antioxidant even the experts have difficulty pronouncing: anthocyanin, which also produces the deep red colour of pomegranates and many berries. “It helps protect the skin from free-radical damage,” Guy explains. “And the vitamin C boosts the collagen in the skin.”

Carter recommends all kinds of berries and also loves their combination of vitamin C and antioxidants. “You get the double whammy,” he says.

Carrots are high in beta-carotene, which turns to vitamin A – the skin’s ‘superfood’.

OLIVE OIL

Alwill bathes in the stuff. Well, almost. “I’m not going to lie here, I often put the olive oil I use in my food directly on to my skin, too,” she says. “That’s the beauty of natural ingredients. The vitamin E present in olive oil supports the repair of dry and damaged skin when ingested or applied topically. It’s also delicious, which is a bonus.”

She adds that an indirect benefit is that healthy fats such as olive oil (extra virgin only if you want the full health benefits) help to stabilise blood-glucose levels.

What has this got to do with skin? “It means we’re not reaching for sugar-rich and carb-rich snacks between meals, which can be detrimental to our skin.”

BRASSICA VEGETABLES

From the mustard family, brassicas include radishes, turnips, swedes, cauliflower, broccoli, brussels sprouts and cabbage. Oh, and that hipster ingredient that’s great for our skin, if not our taste buds: kale. No wonder it’s become ubiquitous in everything from our smoothies to our dinner bowls

“Brassicas contain sulphur, which is really important for producing collagen, which helps tone and structure,” Guy explains, adding that fermenting these vegetables – think kim chi and sauerkraut – helps to turbo-charge this effect.

GARDEN BITS

Micro herbs and flowers are not just a trend in our food scene, they are a trend in our skin scene. If you’re plucking flowers and herbs from the garden and adding them to your plates, it might pretty up the food pictures on your Instagram feed (because that’s all that matters right, along with skin-airbrushing apps!) as well as your skin.

“Organic herbs such as parsley, coriander, basil, mint, oregano, thyme and sage have traditionally been used because they’re rich sources of chlorophyll, beta-carotene and minerals, and because they have antimicrobial and antioxidant properties,” says Koullouros. “They’re excellent for skin health. I use a handful in meals twice a day.”

Carter adds that freshly picked marigolds, or the slightly more obscure burdock root, can make a tasty, skin-friendly tea. “It’s wonderful for boosting the lymphatic system and circulation just under the skin.”

CARROTS

Two things please me about the experts’ food choices. The first is that they are, for the most part, ordinary foods with names we can pronounce (I was semi-expecting a show of naturopathic one-upmanship, a battle involving exotic roots from the Himalayas or various forms of marine plasma). And the second is that they’re affordable and readily available.

This is epitomised by the humble carrot, one of Guy’s favourite skin foods. “Carrots are high in beta-carotene, which turns to vitamin A,” she explains.

Vitamin A is the skin’s “superfood”, as it stimulates collagen and elastin, as well as normalising blood flow to reduce the appearance of redness and increase the speed at which wounds heal.

But don’t go bananas on the carrots: a couple a day are enough to benefit your complexion and eating too many can have an adverse effect on your skin. “I’ve had some orange clients,” Guy admits.
