Eating is getting worse acne? Part 2 – The Journal Scan
The role of diet in the development of acne is a controversial issue for a long time. Although reports of several cases, surprisingly, very few systematic studies have been dealing with this problem.
Fulton et al (JAMA, 1969) in a short-term study of 65 patients showed that there was no link between chocolate consumption and acne, sebum production and composition, and comedogenicity. And 'interesting to note that the chocolate bars used in theirStudy was part of the milk very low, unlike a typical bar of chocolate at that time. The perceived connection with commercial products, chocolate can, therefore, a consequence of the presence of milk in them. The studies referred to above has been refuted by Bruce and Laila Mackie (Australian Journal of Dermatology, 1974) for failure to pay compensation for the dietary properties of chocolate. It is suspected that fats with higher melting point can reduce the flow of sebum, and then plugBlackheads are the primary lesions of acne.
In another study, patients were fed large quantities of food that they believed that their acne worse, but no effect was evident after one week. (Anderson, PC, American Family Physician, 1971) have found.
Instead, as early as 1949, Robinson had been reported in South Medical Journal, 1925 patients have led to food diaries had been found that milk was the food most commonly associated with their acne flares.
ThePresence of acne in young blacks (a traditional food diet), both in Zambia and Kenya is much lower than that reported by young blacks in the United States observational studies that a low-fat and high in fiber and can be refined diet low carbohydrate to obtain an advantage acne (Frank, 1971; Kaufman, 1983; Ringsdorf et al, 1976).
A study by nutritionists at RMT University of Melbourne found a significant improvement in acne lesions of 25 teenagers, when they were introducedlow glycemic index (GI) foods rich in carbohydrates such as bread, pasta and vegetables with lean meats and fish. High glycemic index carbohydrate increases stimulate the release of insulin in the blood.
Recent research has shown that hyperinsulinemia promotes a cascade of hormonal effects, the unregulated growth of tissue and increased production of androgens. Note that members of two major pathological events in the case of acne (hair follicle epithelium, andAndrogen-mediated sebum production) are induced by hyperinsulinemia!
To determine if the milk or other dairy products with acne outbreaks, Adebamowo at Harvard University and his team analyzed questionnaires from 47,335 women in the National Nurses Health Study Section (Journal of the American Academy of Dermatology, 2005) is connected. They found a positive correlation with acne for intake of total milk and skim milk.
The same team, under the direction of a Adebamowoprospective study of American girls aged between 9 and 15 years in 1996, noted that the increase in milk consumption was associated with a higher prevalence of acne. They found no association with milk fat and acne. Make the hypothesis that the combination of hormones and other biologically active compounds in milk are primarily caused, may, when most of the milk available in the market in pregnant cows will be.
The relationship between the consumption of dairy products and an increase in teenage acne mayalso explained by the high content of iodine in milk. Farmers give their cows iodine-enriched feed to prevent infection. They also use an antiseptic solution of iodine on their udders of cows and milking facilities.
Another important study by Loren Cordain et al in Archives of Dermatology (2002) found no evidence of acne between 1200 Islanders Kitavan age of 10 years or more, 300 of whom are between the ages of acne "" 15 and 25 years. They mainly eat fruit, fish, onions and coconut, butalmost no wheat or refined sugar. The researchers also saw no acne among 115 Ache hunter-gatherers, including 15 for the age of 15 25. Their diet consisted mainly of cassava fresh root vegetables, peanuts, corn and rice, as well as a game. Approximately 8% of the diet, have formed the Western food such as pasta, sugar and bread. The report also cites previous studies which found that acne is rare or absent in people who are in non-industrialized countries (non-fast-food)Cultures, but when they transit to a Western lifestyle seems.
These results are certainly very contrary to the belief of many dermatologists, there was no link between diet and acne!
Parker Magin et al (Family Practice, January 2005) "A systematic review of evidence for 'myths and misconceptions' in acne management: diet, face washing and sunlight". states that can not be based on the current state of clinical evidence in their teaching recommendationsdeny the influence of diet in patients with acne, that is, they can not sustain the relationship acne diet as a whole.
As a physician, the quarter century of clinical experience behind me, 18 years as a dermatologist, I would say that I am personally convinced that a special relationship, both positive and negative, between acne and food. Acne has a complex etiology, with abnormal thickening and obstruction of hair follicles,altered hormonal function, the growth of bacteria and the immune system. Individual variations that contribute to genetic predisposition, environmental factors and stress are also on the course of the disease. Therefore, all decisions relating to food restriction in the management of acne should be highly individualized carefully prepared and controlled by the patient and the dermatologist physician.
