Whatever time of year the weather can take a toll on our skin. Cold, windy weather in winter and sunshine in the warmer months both have a potentially damaging effect on our skin. A good skin care routine and sun protection are vital; and so too is your diet.
As our skin is on show every day, it can profoundly affect the way we feel about ourselves. If your skin looks good, you feel good too.
It’s amazing the difference eating the right foods can make not only to the appearance of your skin, but also helping ensure your skin at all levels retains its health and integrity.
Skin is your body’s largest organ. It weighs about 4 kg (9lbs) and has a surface area of around 2 square metres (22 square feet).
We rub off millions of dead skin cells daily and create a completely new top layer of skin about every 40 days.
Each square centimetre of skin contains approximately 70cm (28”) of blood vessels, 55cm (22”) of nerves, 100 sweat glands, 15 sebaceous (oil) glands and 230 sensory receptors.
No other organ is so exposed to damage and disease from exterior sources. This can be from injury, sunlight, smoking, environmental pollution and germs. Your skin also reflects internal conditions and emotions such as blushing, uneven skin tone and fatigue.
To keep skin healthy, it must be supplied continually with oxygen, vitamins, minerals, essential fats and protein via the body’s tiny arteries. Its network of small veins removes carbon dioxide and other waste materials.
Skin is not just a simple, thin layer that holds the body together. It has several key functions.
Insulates and Protects – it acts as a barrier protecting underlying tissue from physical damage, bacterial invasion, dehydration and UV damage.
Regulation of Body Temperature via perspiration helps lower elevated body temperature to its normal level. In response to low temperature production of sweat is decreased. Changes in blood flow to the skin also help regulate body temperature.
Sensation. The skin has many nerve endings and receptors that detect stimuli related to temperature, touch, pressure and pain.
Excretion. As well as removing heat and some water from the body, sweat is also a vehicle for removing a range of organic compounds.
Immunity. Certain cells in the epidermis are important components of the immune system, protecting us from foreign invaders.
Blood reservoir. The dermis carries a network of about 8-10% of our total blood flow, and during moderate exercise this may increase further.
Synthesis of vitamin D. This begins with activation of UV rays from sunlight. Vitamin D is subsequently transported by the blood to where it is required in the body.
Absorption. Topically applied substances are absorbed through the surface of the skin. Products that work in this way include nicotine patches and patches to prevent motion sickness.
Approximately 24% of the population consult their GP with a skin problem in any 12-month period and this figure is increasing at a rapid rate.
Individuals consult on a wide range of skin conditions including atopic eczema, cold sores, rashes, athletes’ foot, acne, alopecia and skin cancer.
Unfortunately, skin cancer rates are increasing and outcome often depends on early diagnosis.
The epidermis is the layer of skin “on show” which consists of about 5 layers of cells.
Underneath the epidermis is the dermis, where there is a real hive of activity.
This is where collagen, elastin and reticular fibre are found. These proteins give our skin its strong, yet elastic properties.
The dermis is packed with tiny arteries, veins, lymph vessels and nerve fibres. This is where the oil producing glands are found, along with the hair roots that cover the skin on your face and body.
To function optimally and retain its health and integrity we need to supply our skin with the right balance of essential nutrients on a regular basis. A good diet nourishes the skin from within.
A low nutrient diet will have a detrimental effect on your skin. This type of diet will typically be high in sugar, refined and processed foods and caffeine.
Here are my top tips for healthy, radiant skin.
Anti-ageing. Help prevent skin damage by minimising the effects of oxidation from external pollutants and environmental factors.
Oxidative damage contributes significantly to serious forms of skin damage and also the formation of wrinkles and lines.
By including antioxidants in your diet, you can help control this damage.
Foods high in antioxidants include sweet potatoes, carrots, apricots, berries, citrus fruits, watercress, rocket and kale.
Detoxification. Minimise the “toxic load” you give your body by reducing your intake of caffeine and alcohol which gives your liver an extra burden to deal with.
Caffeine is found in tea, coffee and cola drinks.
By cutting down on these you will help support liver function and may also reduce any dark shadows under your eyes. Healthy skin has an unmistakable vibrant glow.
Herbal or green teas are good alternatives to caffeinated drinks and plain water is a great substitute for cola.
Identify Food Sensitivities. These will affect skin health, so investigate and identify any sensitivities. The most common are gluten and diary intolerances.
Strong and Supple. Collagen is a protein produced by our cells that helps retain the skin’s elasticity and firmness. When we’re young our skin stays strong and supple because the collagen constantly regenerates itself.
As we age collagen production slows and our existing collagen may become damaged, often due to sun exposure and poor diet.
Vitamin C is essential for the formation of collagen, so make sure your diet contains good levels of this vitamin every day. It is found in many fresh foods including citrus fruits, tomatoes, green vegetables and salad ingredients.
Texture and Tone
Some fat is good for you and eating the right type of fat is essential.
Most people do not include enough foods that contain essential fats in their diet. These Omega 3 and Omega 6 essential fatty acids give good, even skin tone and help prevent dry skin.
Excellent sources of essential fats include oily fish, such as salmon, tuna fish, mackerel and sardines, natural nuts, such as almonds and cashews and seeds, such as sunflower and pumpkin. Also use extra virgin olive oil to make dressings and in some of your cooking.
Youthful Glow
Anthocyanidins found in berries, such as strawberries, blueberries, blackberries and raspberries help maintain the springy texture associated with youthful skin.
Try adding these to your breakfast cereal, smoothies and natural yoghurt.
Plump and Hydrated
Water and foods with a high-water content help keep the skin plump and hydrated. Aim to drink about 8 glasses of still water each day and include foods in your diet such as bell peppers, celery, cucumber, salad leaves, pineapple, kiwi fruit and melon.
Skin wound healing. A good diet containing optimal levels of essential nutrients will help support healthy wound healing and ensure the epidermis is restored to normal thickness.
Exercise. Regular exercise is one of the key factors in having a healthy skin. Anything that promotes good circulation will also help keep your skin vibrant and youthful.
Regular exercise helps tone muscles, and firmer muscles improve the appearance of our skin.
Combine good diet and regular exercise and see the difference it makes.
Whatever your age it’s never too late to start eating healthily to improve not only your skin, but your overall health and wellbeing.
Start today and see the difference!
