Lacteos y acné, estudio dice que no hay gran diferencia.

Yo les hablo a los pacientes sobre mi idea de que sí hay relación entre la dieta y el su acné, en algunos pacientes, y si ellos establecen que sí hay un nexo, que difieran de ingerir estos alimentos.

Éste artículo establece que no hay una correlación directa, pero no niega la asociación.

BACKGROUND

Recent literature has implicated dairy as having a potential acne-inducing effect.

OBJECTIVES

The aim of this study was to investigate the link between dairy consumption and acne in teenagers. We tested the hypothesis that teenagers with facial acne consume more dairy than those without acne.

METHODS

A case-control study was conducted among 225 participants, ages 14 to 19 years, with either moderate acne or no acne. Moderate acne was determined by a dermatologist using the Global Acne Assessment Scale. Participants who met inclusion criteria then completed up to three 24-hour diet recall interviews using the Nutrition Data System for Research software and food and nutrient intake were compared between groups.

RESULTS

The amount of low-fat/skim milk consumed by participants with acne with significantly higher (P = .01) than those with no acne. No significant difference was found among total dairy intake, saturated fat or trans-fat, or glycemic load. No significant difference was found for total energy intake or body mass index.

LIMITATIONS

Limitations include self-report of diet and portion size, and association does not determine causation.

CONCLUSIONS

Consumption of low-fat/skim milk, but not full-fat milk, was positively associated with acne.

TAKE-HOME MESSAGE

• This case–control study evaluated the link between dairy consumption and acne in 225 adolescents aged 14 to 19 with and without acne. Participants completed three telephone interviews to provide 24-hour dietary recalls. The average total dairy consumption overall was 2.51 servings per day. The acne group consumed more dairy overall than the controls (P = .02) and consumed more low-fat/fat-free dairy (P = .03). An analysis of total low-fat/skim milk consumption, excluding other dairy products, found significantly higher consumption in acne patients (P = .01). Reduced-fat and full-fat dairy consumption was not statistically different between the groups. Total glycemic index, glycemic load, and macronutrient intake were not different between the groups.

• This study found a positive association between low-fat/skim milk consumption and moderate acne in teenagers, but no association between acne and full-fat dairy consumption. However, further research is needed before changing dietary recommendations for patients with acne.
