What You Eat Shows…On Your Skin

Not only are skin specialists now convinced of the link between what we eat, and the look and feel of our skin – from acne to wrinkles, to sagging and even the skin’s own sun-protection – increasingly large scientific studies are also showing which foods do what to skin.

Hearteningly, this means that depressing old aged: ‘it’s in the genes’ isn’t the whole story, and there is plenty you can do to influence the state of your face.

‘Only 20 per cent of the way you age is down to genetic factors,’ says leading celebrity dermatologist Dr Neetu Nirdosh, whose client list includes Kelly Brook and Frieda Pinto.

‘The other 80 per cent is governed by lifestyle factors such as smoking and sun damage.

‘A large part of that is diet, which can affect not only wrinkles and fine lines, but also hyper-pigmentation and acne’.

WHAT NOT TO EAT 

It’s never too early to adopt a skin healthy diet geared towards anti-ageing, says Dr Stefanie Williams, dermatologist and founder of www.eudelo.com.

In fact, a study published in the British Journal of Dermatology found that ageing effects the skin – such as collagen breakdown and skin thinning – typically begin around 35.

‘A diet high in sugar and high-glycemic index (GI) carbohydrates such as white rice, pasta, bread, and sweets have now been shown to cause inflammation in the body that can make the skin age much quicker,’ Dr Williams said.

One study, from the Leiden University Medical Centre in the Netherlands, made the first direct link between the amount of sugar circulating in the blood, and how old a person looks.

It found the higher the amount of sugar and high GI carbs a person ate, the older they looked.

Here’s what’s happening. When blood sugar levels are constantly on the high-low cycle that comes from a high sugar and high carb diet, (eating too often between meals has the same effect), sugar molecules permanently bond to proteins, including the collagen in your skin.

Where once we as dermatologists dismissed the idea of diet and pimples, there is now good evidence of a link between unrefined sugars, sweets, milk chocolate, and unrefined carbohydrates with increased incidence of acne breakout

This is a process known as glycation, and produces aptly named compounds called AGES, or Advanced Glycation End Products (AGES), that cross-link with proteins, Dr Williams said.

‘Consequently, tissues become stiff and inflexible, skin becomes tougher, saggier, and wrinkles form often prematurely,’ she added.

A diet high in dairy may elevate hormone levels and contribute to acne, said Professor Nicholas Lowe, a London-based dermatologist.

‘Where once we as dermatologists dismissed the idea of diet and pimples, there is now good evidence of a link between unrefined sugars, sweets, milk chocolate, and unrefined carbohydrates with increased incidence of acne breakout,’ she said.

When he puts patients with inflammatory skin conditions, such as acne, psoriasis, and eczema, on diets reducing their intake of refined sugars and dairy products, Dr Lowe explained, their conditions often get better.

‘Changing their diets can reduce the severity of their conditions,’ he said.

Sticking to low-GI diet (eating foods with a GI of 50 or under) and avoiding sugary foods will help your skin.

But if you want to keep blood sugar levels stable, and reduce breakouts and help early ageing in the skin, Dr Williams suggested avoiding all starchy, grain-based foods, even the brown versions.

Instead, she advised eating lean proteins such as beef, lamb, chicken, fish, tofu, and pulses, and plenty of vegetables.

‘Avoid sweet tropical fruits and have fresh fruit in moderation,’ she said.

‘Except all types of berries. They’re high in antioxidants that bring great anti-ageing benefits to the skin.’

DITCH THE LOW-FAT DIET

Your low-fat diet could be sabotaging your face, said Dr Nirdosh.

‘You might get someone that is really thin, and is eating a lean, low-fat diet, and drinking plenty of water, but their skin may look dry, dehydrated, and with a certain grey colour,’ she explained.

‘That’s dehydration because they don’t have enough good fat content in their diets which means the skin is unable to retain its water, and more moisture is evaporating from its surface, especially in air-conditioned, or heated environments.’

She suggested eating good fats such as coconut oil for cooking, nuts such as almonds, Brazils and walnuts, avocados and oily fish.

WHY YOU SHOULD EAT – NOT DRINK – YOUR WATER

Skin legend Dr Howard Murad, founder of Murad skincare and associate professor of medicine at UCLA says damaged skin cells have a weakened ability to retain water, so skin loses elasticity, tone, and surface moisture.

‘Puffy eyes, swollen ankles, and even a bloated stomach are also signs the body isn’t handling water efficiently,’ he said.

‘It also explains some of the early signs of ageing that might occur in your early 30s, particularly skin becoming drier and feathery lines emerging.’

But he too agrees that guzzling water won’t solve the problem.

‘Consuming fruits and vegetables that are high in water more efficiently rebalances the water in your system because these foods are surrounded by molecules that help deliver the water they contain into cells more easily,’ says Dr Murad.

‘For this reason I encourage patients to eat – not drink – their water.’

Foods highest in water content include:

* watermelon and cucumbers: 97 per cent

* broccoli, and spinach (92 per cent)

* apricots (86 per cent), pomegranates (82 per cent) and avocados (82 per cent).

‘These contain essential lipids that create a protective surface around the skin cells and prevent essential water within them, from escaping,’ said Dr Nirdosh.

Fascinatingly, scientists at Manchester University have even found that certain foods can increase the natural sun protection in your skin.

‘When tomatoes and the foods made from them such as salsa and ketchup are consumed regularly, patients’ skin can over time become less susceptible to sunburn,’ explained Dr Tamara Griffiths, president of the British Skin Foundation.

‘This is thanks to the lycopene content in tomatoes which appears to have the skin-protective benefits,’ she said.

Some also believe that compounds called flavonoids in citrus foods, green tea and pomegranate and another called resveratrol found in red grapes (and happily, red wine) could have the same effect.

‘Of course, this isn’t in place of a sunscreen but it may help the skin’s own protection in areas sunscreens don’t reach,’ Dr Griffiths said.

So, is there a diet out there that beats others hands down in skin-friendly treasures that is do-able enough for the rest of us to stick to?

‘Probably the Mediterranean diet,’ she said.

‘Overall, it’s high proportion of omega-3 rich fish and it’s naturally occurring antioxidants in all the different coloured vegetables it emphasizes is probably the best – and most realistic – healthy diet for skin.’
