Dietary Regimes For Treatment Of Acne Vulgaris A Critical Review Of Published Clinical Trials

Researchers reviewed clinical studies to determine whether specific dietary changes can help treat acne vulgaris, the common form of acne that affects millions of people. They found only six studies that actually tested dietary interventions, focusing mainly on low glycemic load (LGL) diets - eating plans that minimize blood sugar spikes by avoiding high-sugar and refined carbohydrate foods.

Of the four studies examining low glycemic diets, only two showed significant improvements in acne lesions. This suggests that while reducing sugar and refined carbs might help some people's skin, the evidence isn't strong enough to make definitive recommendations. The researchers also looked at two studies on chocolate's effect on acne - one older study from 1969 found no connection (and some participants' skin actually improved), while a 2014 study found that cacao capsules did worsen acne.

The review revealed significant limitations in the existing research. All studies had small participant groups (13-65 people), used different methods to measure acne severity, and several had high dropout rates. The authors noted that while observational studies suggest dairy products may worsen teenage acne, no intervention studies have been conducted to prove this connection.

From a metabolic health perspective, this research highlights the complex relationship between diet, blood sugar regulation, and skin health. While the evidence for low glycemic diets helping acne remains preliminary, this approach aligns with broader metabolic health principles. In clinical practice, healthcare providers may consider dietary modifications as part of a comprehensive acne treatment plan, though more robust research is needed to establish clear guidelines.
