DietAs a naturopath I see acne is an external manifestation of an internal imbalance, with nutrition being one of the keys to treating it. Excess sugar, trans fats, salty, fried and processed foods cause a buildup of toxins in the body which are excreted through the skin as its way of getting rid of them. This is when we get pimples and blackheads that push through the surface of the skin and is called acne.
FatsWhen we eat fats our body makes oils or sebum, which is then secreted from the sebaceous glands. If we choose poor quality fats such as (saturated fats, and trans fatty acids) that come from highly processed and commercially baked products, the body produces oil that doesn’t not flow very well because it’s thick and sticky, clogging pores which can attract bacteria. Good quality oil on the other hand flows well and nourishes the skin. Good oils includes deep sea fish such as tuna, mackerel, salmon, herring and sardines, and plant oils such as flaxseed and olive oil. Approximately three out of four teenagers will suffer with some form of acne during their lives, and while 95 per cent of sufferers are in their teens, the other 5 per cent will develop adult onset acne later in life.
Sugar and diet choices.When we eat simple carbohydrates such as cakes, biscuits, or white bread they are broken down into sugar and sent into the blood stream. Insulin is then produced to take these sugars into our cells, to be stored as fats for later energy production. The presence of the insulin then stimulates androgens or male hormones to be produced, which increase sebum production, and pimple formation. A recent Australian study followed two groups of teenage boys for 12 weeks, onegroup consuming a low GI, high protein diet, and the other eating a more typical adolescent diet. The low GI group experienced a 50% improvement in their acne symptoms, while the control group (who used anti-acne skin creams) didn't see such results. The low glycaemic load diet was also associated with weight loss as well as a reduction in androgens when compared with the high glycaemic load diet, as was reported in the August 2008 issue of the Journal of the American Academy of Dermatology. (1)
The outcome of this study suggests that a diet of processed foods increases sugar and insulin levels to a high level and make acne worse. Those who consumed the low glycaemic foods (or sugars from foods that take longer to be digested such as vegetables and fruits), have the opposite effect. The research could also explain why acne is more prevalent in industrialised nations, and is relatively uncommon in the developing world.
The other problem with eating a highly refined, sugary and processed diet is the negative effect it has on the good bacteria in the digestive tract. Basically they are reduced in numbers and allow opportunistic yeasts and bacteria to populate the digestive tract. This also occurs when antibiotics are taken, with the need to replace them with Lactobacillus acidophilus. An easy way to encourage teenagers and young children to consume these is by drinking products such as Lemon and ginger, BE Wholegrain Liquid, or Cocobiotic daily, available from Grainfields at

Milk and hormones.
Dairy is often high in butterfat and milk sugars, both of which are thought to aggravate acne, but The Harvard Nurses’ Study which studied 47,000 women, found that women who drank milk were more likely to have acne. Interestingly the problem was not the milk fat, because skim milk was worse than full-fat. Dermatologist Bill Danby from the Dartmouth Medical School believes that hormones are to blame. Cow’s milk contains many hormones, including a type of testosterone called DHT that is known to cause acne. High amounts of hormones are produced by cows, especially pregnant cows, and these are present in their milk. When these hormones are broken down they turn into dihydrotestestosterone (DHT), a molecule that switches on oil-making cells, as mentioned earlier during insulin production. US researcher Dr Jerome Fisher conducted a clinical study of over 1000 acne-prone teenagers over 10 years, and noticed their acne symptoms reduced when their milk consumption did. (2)
WaterThe cells in our bodies /skin need water to function properly, and when they become dehydrated they cannot take in nutrients or expel waste products efficiently, therefore becoming constipated. The pores of the skin then become blocked and pimples form. When the body doesn’t have enough water, it will try to conserve what it has, and fluid retention results putting pressure on the skin causing more pores to become blocked. When skin cells are not able to function properly there is less ability for the cells to repair and nourish the skin.
StressIt is common for stress from work, study or relationship and financial issues to bring on a breakout. Studies in Germany have shown that the hormone corticotrophin-releasing hormone (CRH), caused production of oily skin when released from the sebaceous gland. Dermatologist Dr. Jerome Litt believes that stress and acne are linked, adding that in stressful situations there is also an increase in testosterone and androgens (male hormones), which accounts for increased oil production. Stress also affects metabolism, appetite and the motivation to exercise and eat healthily, which may make acne symptoms worse. Exercise and dry skin brushing encourage the lymphatic system to release toxins through the skin and avoid build up in the body by providing oxygen to the skin cells. Exercise increases metabolism, balances hormones and reduces stress.
Cosmetics and MedicationsThe use of products containing oily substances such as mineral oil, rich creams or make up and petroleum based products can set off or worsen acne. Some cosmetics can irritate the skin and flare-up acne. Certain medications like steroids can also stimulate acne production.
Nutrient deficienciesDeficiencies of zinc, essential fatty acids (omega 3) and vitamin A may cause skin problems, as they are important nutrients for the skin. If the skin is dry, flaky, inflamed, has blackheads or whiteheads, this may suggest an essential fatty acid deficiency. Zinc prevents scar formation and is essential for repair of the skin. Rough, thick or acne prone skin may be a sign of vitamin A deficiency.
