According to the American Academy of Dermatology, "you are what you eat” is an adage that often applies to skin care...
The findings from a new study suggest another reason why diets that contain low glycemic loads may be of benefit. Not only can they improve insulin sensitivity, this type of diet also appears to clear up acne as well.
Data from earlier studies suggest that dietary factors such as the glycemic load are involved in the pathogenesis of acne. Therefore, changes in diet could impact symptoms of this common skin disease, the researches hypothesize.
Foods that produce a high glycemic load—or high levels of blood glucose—such as white bread and potatoes tend to cause a rapid surge in blood sugar. Conversely, other carbs, such as high-fiber cereals or beans, create a more gradual change and are considered to have a low glycemic index.
Dr. Robyn N. Smith, from the RMIT University in Melbourne, Australia, and colleagues assessed acne symptoms in 43 male patients, between 15 and 25 years, who were randomly assigned to a low glycemic load diet or a normal diet for 12 weeks. The intervention diet consisted of 25% energy from protein and 45% from low-glycemic-index carbohydrates.
The findings are published in the July issue of the American Journal of Clinical Nutrition.
The low-glycemic diet was associated with a significant reduce in total acne compared with the normal diet. In addition, the low-glycemic diet produced significantly greater reductions in body weight and body mass and a greater increase in insulin sensitivity. Insulin resistance is a condition in which the body’s cells become insensitive to the effects of insulin, so the body’s response to a normal amount of insulin is reduced. As a result, higher amounts of insulin are needed for this hormone to work in the body.
Smith and her associates point out that this study is the first randomized controlled trial to examine the influence the effects of glycemic load on acne.
“Although we could not isolate the effect of the low glycemic load diet from that of weight loss,” they add, the findings support the hypothesis of a relationship between acne and high insulin levels.

Scientists have discovered that an extract of broccoli sprouts protects the skin against the sun's harmful ultraviolet rays.
The best way to reap the health benefits of fruits and vegetables without exposing yourself to potentially harmful pesticides is to choose organic produce whenever possible, especially those varieties which are more likely to be contaminated. But if organic produce is cutting into your budget, it's okay to buy non-organic varieties of the fruits and vegetables listed below, which tend to contain the least amount of pesticides. However, make it a habit to wash them thoroughly before eating or cooking, to remove dirt and bacteria.

The link between nutrition and beauty is inspiring a new breed of beauty products. Marketers are recognizing the value of rolling health care and beauty into overall treatment programs supported by eco-friendly products, and both manufacturers and consumers are feeling their way through a transition as conscience and economics converge.
People who unwind with a cup of tea every night may have a lower risk of two common forms of skin cancer, new research suggests.
In a study of nearly 2,200 adults, researchers found that tea drinkers had a lower risk of developing squamous cell or basal cell carcinoma, the two most common forms of skin cancer.
Men and women who had ever been regular tea drinkers -- having one or more cups a day -- were 20 percent to 30 percent less likely to develop the cancers than those who didn't drink tea.
The effect was even stronger among study participants who'd been tea fans for decades, as well as those who regularly had at least two cups a day, according to findings published in the Journal of the American Academy of Dermatology.
However, the findings do not mean it's okay to bake in the sun as long as you have a cup of tea afterward. The researchers found no evidence that tea drinking lowered skin cancer risk in people who'd accumulated painful sunburns in the past.
Nor did the study look at the relationship between tea drinking and malignant melanoma, the least common but most deadly form of skin cancer.
Still, the findings support the theory that tea antioxidants may limit the damage UV radiation inflicts on the skin, according to the study authors, led by Dr. Judy R. Rees of Dartmouth Medical School in Lebanon, New Hampshire.
In particular, a tea antioxidant known as EGCG has been shown to reduce burning on UV-exposed skin.
The current findings are based on interviews with 770 New Hampshire residents with basal cell carcinoma, 696 with squamous cell carcinoma, and 715 cancer-free men and women the same age.
Tea consumption was linked to a lower skin cancer risk, even with factors such as age, skin type and history of severe burns considered. However, tea drinkers who'd suffered multiple painful burns in the past did not have a lower risk of skin cancer.
It's possible, the researchers explain, that the antioxidants in tea are enough to limit skin damage caused by moderate sun exposure, but not the "more extreme" effects of sun exposure, such as cancer-promoting damage to the DNA in skin cells.
