Hormonally, elevated androgen and growth hormone levels has been associated with acne exacerbations. Environmentally, it has been postulated that diets associated with a high glycemic index (GI), and the consumption of milk and chocolate, can exacerbate this condition<a class="elsevierStyleCrossRefs" href="#bib0040">1–3</a>.GI represents a score from 1 to 100 that expresses how quickly a carbohydrate is digested, absorbed, and metabolized<a class="elsevierStyleCrossRef" href="#bib0045">2</a>. Diets with a high GI have scores > 55. The Western diet is characterized by the consumption of dairy and high-glycemic foods.Meixiong et al.<a class="elsevierStyleCrossRef" href="#bib0045">2</a> conducted a systematic review evaluating the association of a high-GI diet and/or dairy intake with acne pathogenesis. They included a total of 34 articles (n=120,398): 28 were observational studies (42.9%, case-control studies; 14.3%, longitudinal cohort studies; and 42.9%, cross-sectional studies) and 6 were controlled clinical trials (5 were randomized and 1 non-randomized). A total of 77% of the 18 observational studies performed showed an association between high-GI diets and acne severity. Smith et al.<a class="elsevierStyleCrossRef" href="#bib0050">3</a> randomized a total of 43 acne patients treated with facial cleanser to receive a low-GI diet (GI=43) or a control diet (GI=56) for 12 weeks. The low-GI diet group experienced better results than the control group: a decrease in the number of lesions -16 in the low-GI group vs –8.5 in the control group (p=0.04).Conforti et al.<a class="elsevierStyleCrossRef" href="#bib0040">1</a> conducted a review on foods that may be involved in acne pathogenesis and the pathophysiological explanation of the molecules involved (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>). High-GI diets are associated with hyperinsulinism, which leads to an increase in androgens, insulin-like growth factor 1 (IGF-1), and IGF-3, contributing to the development and worsening of acne1. Carbohydrate-rich diets are associated with hyperglycemia, reactive hyperinsulinemia, and elevated levels of IGF-1. However, a Mediterranean diet (MD), characterized by low-glycemic-load foods, minimal dairy intake, and an abundance of nutrients with antioxidant and anti-inflammatory properties such as fruits and vegetables, may decrease the signaling produced by IGF-1 and, consequently, acne<a class="elsevierStyleCrossRef" href="#bib0055">4</a>. These foods contain hydroxytyrosol, tyrosol, oleocanthal, and resveratrol, phenolic compounds with anti-inflammatory properties. Recently, Ah-Thiane et al.<a class="elsevierStyleCrossRef" href="#bib0060">5</a> published a case-control study<a class="elsevierStyleCrossRef" href="#bib0060">5</a> (n=80) to determine the relationship between acne severity in French women and adherence to the MD. In acne patients, a significant negative correlation was found between acne severity determined by the Global Evaluation Acne (GEA) scale and adherence to the MD, with a Spearman correlation coefficient of r=-0.47; p<0.001.<elsevierMultimedia ident="tbl0005"></elsevierMultimedia>Morales-Sánchez et al.<a class="elsevierStyleCrossRef" href="#bib0065">6</a> recently conducted a clinical trial (n=52) with male patients aged 18 to 25 with moderate acne using the same treatment (topical adapalene 0.1% and systemic doxycycline 100mg daily). Patients were randomized into 2 groups based on whether they would receive a low-glycemic diet or a control diet, observing a statistically significant reduction in acne lesions in patients on the low-carbohydrate diet at 12 weeks.Although more clinical trials are needed to establish whether there is a clear relation between high-glycemic foods, current studies anticipate a protective role of the MD in acne. Regarding dairy, to date, only 1 positive association between increased intake of these foods and worsening acne in Western populations has been reported.We recommend a diet based on the consumption of fruits, vegetables, whole grains, nuts, extra virgin olive oil, fish, white meats, and a restricted intake of red meats, dairy, and sugary products."

A deficiency in FoxO1 can be seen during puberty growth hormone signaling and with increased insulin/IGF-1 signaling due to the consumption of insulinotropic milk/dairy products, and hyperglycemic carbohydrates from the Western diet. This deficiency worsens acne through the proliferation of pilosebaceous keratinocytes, sebaceous lipogenesis, and the expression of perifollicular inflammatory cytokines.6 \t\t\t\t\t\t\n \t\t\t\t</td></tr><tr title="table-row"><td class="td-with-role" title="\n \t\t\t\t\ttable-entry\n \t\t\t\t ; entry_with_role_rowhead " align="left" valign="\n \t\t\t\t\ttop\n \t\t\t\t">SREBP-1 \t\t\t\t\t\t\n \t\t\t\t</td><td class="td" title="\n \t\t\t\t\ttable-entry\n \t\t\t\t " align="left" valign="\n \t\t\t\t\ttop\n \t\t\t\t">Elevated molecular levels associated with worsening acne \t\t\t\t\t\t\n \t\t\t\t</td><td class="td" title="\n \t\t\t\t\ttable-entry\n \t\t\t\t " align="left" valign="\n \t\t\t\t\ttop\n \t\t\t\t">SREBP-1 is a regulator of the production of sapienic acid, a natural antimicrobial.
