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.

A study involving nearly 3,500 women in several countries suggests that Chinese herbs might be more effective in relieving menstrual cramps than drugs, acupuncture or heat compression.
Australia-based researchers said herbs not only relieved pain, but reduced the recurrence of the condition over three months, according to the Cochrane Library journal.
“All available measures of effectiveness confirmed the overall superiority of Chinese herbal medicine to placebo, no treatment, NSAIDs (non-steroidal anti-inflammatory drugs), OCPs (oral contraceptive pill), acupuncture and heat compression,” said lead author Xiaoshu Zhu from the Centre for Complementary Medicine Research at the University of Western Sydney.
Period pain affects as many as 50 percent of women of reproductive age and between 60 percent to 85 percent of teenaged girls, leading to absences from school and work.
While the cause is still under debate, it is believed to be linked to an imbalance in ovarian hormones.
Chinese herbal medicine has been used to treat the condition for hundreds of years and women are increasingly looking for non-drug treatments.
The survey involved 39 trials — 36 in China, and one each in Taiwan, Japan and the Netherlands.
Participants given herbal concoctions were prescribed herbs that regulated their ‘qi’ (energy) and blood, warmed their bodies and boosted their kidney and liver functions.
Some of these include Chinese angelica root (danggui), Szechuan lovage root (chuanxiong), red peony root (chishao), white peony root (baishao), Chinese motherwort (yimucao), fennel fruit (huixiang), nut-grass rhizome (xiangfu), liquorice root (gancao) and cinnamon bark (rougui).
In one trial involving 36 women, 53 percent of those who took herbs reported less pain than usual compared with 26 percent in the placebo group.
But the researchers said more studies were needed because of the relatively small numbers of participants in each of the trials.
