Eat your way to fabulous skin


By Jo Lewin - Nutritional therapist

If you want radiant skin, the old adage 'you are what you eat' has never been more true. Our nutritionist tips will help you nourish your skin from the inside out.

Everyone has a favourite face cream or treatment, but beautiful skin starts with nourishment from within. Older cells are constantly shed and replaced by younger ones and a steady supply of micronutrients is essential to support this rapid growth. Eat the correct balance of foods and you'll feed your skin the vital nutrients it needs to help it stay soft, supple and blemish-free.

Eat your five-a-day
Fruit and vegetables contain powerful antioxidants that help to protect skin from the cellular damage caused by free radicals. Free radicals are caused by smoking, pollution and sunlight and can cause wrinkling and age spots. Eat a rainbow of colourful fruit and vegetables and aim for at least five portions a day. Betacarotene, found in pumpkin, carrots and sweet potatoes, and lutein, found in kale, papaya and spinach are potent antioxidants, important for normal skin cell development and healthy skin tone.

Vitamin C
Vitamin C is also a super antioxidant. It is needed for a strong immune system, radiant skin and helps blemishes heal properly. The best sources are blackcurrants, blueberries, broccoli, guava, kiwi fruits, oranges, papaya, strawberries and sweet potatoes. They all help to produce collagen that strengthens the capillaries that supply the skin.

Cut out crash diets
Repeatedly losing and regaining weight can take its toll on your skin, causing sagging, wrinkles and stretch marks. Crash diets are often short in essential vitamins too. Over long periods of time this type of dieting will reflect on your skin.

Stock up on selenium
Selenium is a powerful antioxidant. It works alongside other antioxidants such as vitamins E and C and is essential for the immune system. Studies suggest that a selenium-rich diet can help to protect against skin cancer, sun damage and age spots. One way to boost your intake is to eat Brazil nuts. Just four nuts will provide the recommended daily amount (RDA). Mix Brazil nuts with other seeds rich in vitamin E as a snack or salad sprinkle. Other good sources are fish, shellfish, eggs, wheatgerm, tomatoes and broccoli.

Vitamin E
Vitamin E protects skin from oxidative (cell) damage and supports healthy skin growth. Foods high in vitamin E include almonds, avocado, hazelnuts, pine nuts and sunflower and corn oils.

Drink up
Skin needs moisture to stay flexible. Even mild dehydration will cause your skin to look dry, tired and slightly grey. Drink six to eight glasses of water a day - all fluids count towards your daily allowance, but water is the best. If you work in an office, keep a large bottle of water on your desk to remind you to drink. Herbal, caffeine-free teas are good too. Try to avoid smoking and excessive alcohol consumption, both can age the skin.
Don't be afraid of fat
Monounsaturated and polyunsaturated fats - the types found in avocados, fish, nuts and seeds - provide essential fatty acids which act as a natural moisturiser for your skin, keeping it supple. These fats also come packaged with a healthy dose of vitamin E (a vitamin many of us lack), which will help protect against free radical damage.

Eat more phyto-estrogens
Phyto-estrogens are natural chemicals found in plant foods (phyto meaning plant). They have a similar structure to the female sex hormone oestrogen and have been found to help keep our natural hormones in balance. There are different types, some are found in soya bean products (isoflavones), whereas others are found in the fibre of wholegrains, fruit, vegetables and flax seeds (lignans). Include phyto-estrogen rich soya, wholegrains, fruits and vegetables as part of a balanced diet.

Opt for omega-3
Make sure you get enough omega-3 and omega-6 fats. These are essential fatty acids which mean they cannot be made in the body and must be obtained through the diet. You will find omega-3s in oily fish and plant sources such as flaxseed oil, linseeds, walnut and rapeseed oil. Omega-3 fats encourage the body to produce anti-inflammatory compounds, which can help skin, particularly inflammatory skin conditions such as eczema and psorasis.

Go for low-GI carbs
Eat plenty of beans, pulses, porridge and other slow-releasing carbohydrates. These release sugar into the blood stream gradually, providing you with a steady supply of energy and leaving you feeling satisfied for longer and therefore less likely to snack. Avoid high GI carbohydrates like biscuits and sugary drinks, as they lead to production of insulin, which may damage collagen and accelerate wrinkles.

Don't forget zinc
Zinc is involved in the normal functioning of the sebaceous glands in the skin (which produce oil) and helps to repair skin damage and keep skin soft and supple. Zinc-rich foods include fish, lean red meat, wholegrains, poultry, nuts, seeds and shellfish.

Common skin problems:
As much as we try to resist it, our skin does age. Wrinkles and age spots are the result of gradual, accumulated damage from the sun, strong soaps, chemicals and poor nutrition. Make sure you follow the guidelines above and try to include antioxidant rich fruit and vegetables containing beta carotene, vitamins C and E, zinc and selenium.

Acne...
...is caused by inflammation and infection of the sebaceous glands of the skin. Sebaceous glands are stimulated by hormones (particularly androgens). To avoid acne, cut back on saturated and hydrogenated fats in margarines and processed foods. Also cut down on junk food as well as foods high in sugar, such as cakes and biscuits. Eat more raw vegetables, wholegrains, fresh fruit and fish. Try to include selenium-rich foods, such as Brazil nuts, cashew nuts, fresh tuna, sunflower seeds, walnuts and wholemeal bread.

Psorasis...
...appears as red skin patches with silvery scales, most commonly on the elbows and knees. The patches are caused by rapid growth and proliferation of cells in the outer skin layers. Patches can be itchy and sore and in severe cases, the skin may crack and bleed. Some people find outbreaks occur when they feel rundown. Sunburn, alcohol, smoking, obesity and stress are also implicated and there may be trigger foods which you will have to identify using an exclusion diet, though always check with your GP before cutting out food groups. Essential fatty acids (EFAs) from fish oil or cold-pressed nut and seed oils are important to include in the diet. It should also be low in saturated fat and include anti-inflammatory herbs such as turmeric, red pepper, ginger, cumin, fennel, rosemary and garlic.

Eczema...
...is a skin condition that usually begins as patchy redness, often on the hands by can appear anywhere on the skin. Although there are many triggers, one of the most common is food sensitivity. The most common offending foods are milk, eggs, fish, cheese, nuts and food additives. Omega-3 fats, zinc and vitamin E may help reduce symptoms.

Finally...

...once you make changes to your diet, don't expect an overnight miracle. It takes six weeks for new skin to emerge up to the surface, so the visible benefits from dietary changes will take just as long. For persistent skin conditions, talk to your GP or consider seeing a dermatologist.

Infections. Heart problems. Even the menopause: What your nightmares reveal about your health


By ANNA MAGEE


Bad dreams may cause us to wake in a cold sweat in the night, but it's not something you would bother mentioning to your doctor. Or should you?
Scientists believe that recurring nightmares could provide vital clues about health and even warning signs about impending illness - sometimes years before symptoms appear.

Last month, researchers found regular nightmares in childhood could be an early warning sign of psychotic disorders later in life. The study, published in the journal Sleep, tracked 6,800 children and found those having frequent nightmares (two to three times a week) between the ages of two and seven were three-and-a-half times more likely to have a psychotic experience, such as hallucinations or hearing voices, as a teenager.

The researchers said frequent nightmares could indicate children are facing  emotional trauma, such as abuse or  bullying, in waking life. They said use of violent video games and computers near bedtime may also play a part.

It's thought we may experience terrifying threats in our nightmares to practise handling them in waking life, explains Patrick McNamara, associate professor of neurology at Harvard Medical School.
But nightmares may also indicate an underlying physical problem that is disrupting our sleep as we dream. We only dream during the stage known as rapid eye movement (REM) sleep. We experience REM, a very light sleep, on average four to five times a night.

Lots of medical problems cause disruption to sleep, which means you're more likely to wake during the REM phase and remember that you had a nightmare, says Dr Nicholas Oscroft, a sleep researcher and cardiologist at Papworth Hospital in Cambridge.
Regular nightmares, could, for example, be a sign of sleep apnoea - this causes breathing to stop temporarily as the airways become obstructed. Patients with sleep apnoea often report frequent nightmares.

A study by Swansea University, in the Journal of Clinical Sleep Medicine in 2011, assessed the dream content of 47 males with sleep apnoea. Those with the most severe symptoms reported the most 'emotionally negative and unpleasant' nightmares.

A study in 2012 in the journal Sleep Medicine found that, when patients were treated for sleep apnoea by wearing a mask that gently forced air into their airways, 91 per cent stopped having nightmares.
Choking attacks and the drop of oxygen to the brain which occur during sleep apnoea can give rise to nightmares, said lead researcher Professor Ahmed S. BaHammam, a sleep medicine expert at King Saud University, Saudi Arabia.

Regular bad dreams can be linked to heart problems, says Dr Oscroft. People who have regular nightmares were three times more likely to suffer irregular heartbeat, according to a study of more than 6,000 adults, published in the Netherlands Journal of Medicine in 2003. Chest pain was seven times higher in those who reported having nightmares often.
One theory, Dr Oscroft explains, is that people with heart conditions, in particular heart failure (when the heart can't adequately pump blood to the lungs and other organs), suffer breathing problems at night.

Heart failure leads to a build-up of water in the lungs, which makes breathing more difficult, particularly at night in REM sleep. This is because most of the muscles become paralysed during this stage, to stop us acting out our dreams; but this can affect the breathing muscles. This can wake people during REM sleep, making them more likely to remember bad dreams.
Any kind of infection, from severe flu to a kidney infection, can make nightmares more likely, explains Professor McNamara.

There are two stages of sleep - REM and non-REM sleep. During the latter, we experience slow wave sleep, when our immune  system is repaired and strengthened. 'When we get an infection, with or without a fever,  the body needs more slow wave sleep,' says Professor McNamara. This is so the immune system can fight  the bug.

However, it has a knock-on effect on REM sleep, he says, 'delaying the point at which we enter dreaming sleep, which can lead to nightmares or bizarre, vivid dreams'. As REM sleep is when we process emotions, this can cause a build-up of unpleasant emotions which may manifest as nightmares.
Frequent violent nightmares can be an early indicator of Parkinson's disease, predating the emergence of symptoms by up to a decade, says Dr Robert Brenner, consultant neurologist at Spire Bushey Hospital in Watford.

Parkinson's is a neurological disorder that causes muscle tremor, stiffness and weakness. The content of some patients' dreams is almost always the same, says Dr Brenner. 'They're being chased or attacked and often act out nightmares, reacting by kicking and punching, so they tend to hurt themselves or their sleeping partners.'

This is because 15 per cent of patients who go on to develop Parkinson's have REM sleep behaviour disorder, meaning they are not paralysed during this sleep phase, and can move about during nightmares. One study, published in the journal Neurology in 1996, found that 38 per cent of patients  with frequent nightmares from REM sleep behaviour disorder developed Parkinson's on average 12.7 years after they began to experience them.

Migraines, too, are often preceded by unpleasant dreams, involving themes of anger, aggression and misfortune, according to a study in Psychotherapy and Psychosomatics in 1996. Around one in four migraine sufferers experiences an aura before an attack: they see flashing lights or zigzags, and hallucinations.

'Sometimes, an aura occurs during REM sleep as a nightmare or very intense, vivid dream, where the aura is experienced as a blinding light or spinning wheel during the dream,' says Professor McNamara.
Many women report more bizarre dreams around the menopause, adds Dr Tony Boret, a consultant gynaecologist at Spire Bushey Hospital. Up to ten years preceding the menopause, levels of female hormone oestrogen significantly drop.

This affects levels of serotonin, a brain chemical associated with hot flushes, mood swings and night sweats, and can lead to sleep disruption in around 15 per cent of women, he says. This can cause excessive tiredness and more  broken sleep. Some experts also believe premenstrual syndrome can lead to more nightmares. A 2008 study found women reported significantly more nightmares than men (30 per cent of women's most recent dreams were nightmares compared with 19 per cent of men).

Study author Dr Jennie Parker, a psychologist at the University of the West of England, said the nightmares were linked to temperature changes that occurred at certain times in a woman's cycle.
The increase in the hormone progesterone, which women experience before a period, causes their body temperature to rise and has been linked to PMS-related insomnia.

This can cause night sweats and hot flushes, as well as vivid dreams and nightmares. 'Premenstrual women tend to dream more aggressively and are more likely to remember dreams,' adds Dr Parker.
Not getting enough shut-eye in the week could explain nightmares during your weekend lie-in.
'People who don't sleep enough tend to miss out on REM sleep,' says Dr Oscroft. REM sleep occurs around 90 minutes after we fall asleep, at the end of each sleep cycle; we experience on average four cycles of sleep.

As each period of REM sleep gets longer through the night, we get more in the latter part. If you're sleep deprived, even by one or two hours a night for a week, when you finally do sleep, you experience REM rebound, getting more dreaming sleep. This is because your brain, which has been missing out on the REM sleep required to process memories, learning and emotions each day, constantly wants to go back into it. 'The build-up of unprocessed emotion can lead to more reported nightmares,' says Professor McNamara.

Sometimes our nightmares can reflect waking health concerns, such as breathing problems. A study published in the journal Dreaming in 2006 found those with breathing problems during wakefulness often reported dreaming about being choked or suffocated; those who perspired excessively while awake often dreamed about sweating.

'Our dreaming brains deal in metaphors and symbols,' says Professor McNamara. 'During REM sleep, the brain tries to capture and process overwhelming sensations, things that are troubling us, or that we can't put into words. It does this through the pictures we see in our dreams.'
