“…NtS are defined as concentrated sources of nutrients or other substances with a nutritional or physiological effect beyond what is supplemented by a normal diet (1), while EA are pharmacological agents used for the purpose of enhancing sports performance (2). Commercial brands have found a profitable market where high performance athletes (3), university students (4) and young amateur athletes (5) avidly supplement their diets with these type of products.…”

López-Samanes Á, Moreno-Pérez V, Kovacs MS, Pallarés JG, Mora-Rodríguez R, Ortega JF. Use of nutritional supplements and ergogenic aids in professional tennis players. Nutr Hosp 2017;34:1463- ResumenIntroducción: los suplementos nutricionales/ayudas ergogénicas (NS&EA) son utilizados en los entrenamientos/partidos de tenis con el objetivo de mejorar el rendimiento. Sin embargo, la literatura científica se encuentras escasos documentos científicos sobre el uso de estas sustancias en tenistas profesionales. Objetivo: describir el uso de NS&EA utilizados por tenistas profesionales durante una temporada. Métodos: se utilizó un cuestionario validado y se evaluó a 62 tenistas profesionales hombres y 9 mujeres (11% entre los 100 mejores del mundo). Resultados: el 81% de los participantes toman al menos un NS&EA. Los preparadores físicos (S&C) y entrenadores de tenis fueron los profesionales preferidos para recomendar NS&EA entre los jugadores fuera del TOP-100 (OT100, 50,7% y 39,1%, respectivamente). Sin embargo, los nutricionistas deportivos fueron los principales asesores de los jugadores entre los 100 mejores del mundo (T100, 62,5%). Las bebidas deportivas fueron los NS&EA más utilizados entre todos los participantes (81,7%). Los tenistas T100 utilizaron cafeína (p = 0,042), creatina (p = 0,001), hierro (p = 0.013) y mezcla de CHO-proteína (p = 0,033) significativamente más frecuentemente que los jugadores OT100. Conclusiones: existe una gran prevalencia de uso de NS&EA entre los tenistas profesionales. Además, los T100 presentan un mayor uso de ciertas sustancias tales como cafeína, creatina, hierro y CHO-proteína. Para el resto de los NS&EA estudiados, el uso fue similar entre los jugadores T100 y OT100. Finalmente, las diferencias en el uso de NS&EA entre grupos pudieran estar relacionadas con los diferentes profesionales escogidos para el asesoramiento nutricional en T100 vs. OT100. AbstractIntroduction: Nutritional supplements and ergogenic aids (NS&EA) are used between training/matches with the goal of enhancing tennis performance. Scientific literature about prevalence and use of NS&EA in professional tennis players is scarce. Objective: The aim of the study was to describe the NS&EA used by professional tennis players during a season. Methods: Using a validated self-administered questionnaire, 62 professional male and 9 professional female tennis players (11% in their gender specific top 100 tennis world ranking (i.e., ATP/WTA)) registered all the used NS&EA. Results: Eighty-one percent of the participants declared taking at least one NS&EA. Strength and conditioning trainers (S&C) and tennis coaches were the professionals who recommended most of the NS&EA in the players outside the TOP-100 (OT100; 50.7% and 39.1%, respectively). However, sports nutritionist were the principal advisors in the top-100 tennis players (T100; 62.5%). Sports drinks were the NS&EA most commonly used by all participants (81.7%). T100 participants used caffeine (p = 0.042), creatine (p = 0.001), iron (p = 0.013) and CHO-protein mix...

Nutrition has long been associated with playing a principal and multifaceted • role in skin health, beauty, integrity, and aging, both directly or indirectly, through multiple pathways and cofactors implicated in skin biology. The onset and the clinical courses of various common skin diseases, including • acne, psoriasis, atopic dermatitis, and hair loss, have been shown to be critically affected by nutritional patterns and habits. Abnormal nutritional conditions, such as obesity anorexia nervosa, manifest in • specific cutaneous appearance features and altered function of the skin. Skin photoprotection, rendered by various nutrients, has been well documented. • Appropriate nutritional supplementation has been shown to exert beneficial • effects on impaired skin's structural and functional integrity, restore its appearance, and promote skin health.

“…Interestingly, the probiotic L. paracasei was shown to decrease skin sensitivity and increase the recovery rate of skin barrier function [12]. Thus, the purpose of this review is to provide an overview of the recent findings on the effects of LAB on skin health and its potential applications in beauty foods.…”

Human skin is the first defense barrier against the external environment, especially microbial pathogens and physical stimulation. Many studies on skin health with Lactic acid bacteria (LAB) have been published for many years, including prevention of skin disease and improvement of skin conditions. LAB, a major group of gram-positive bacteria, are known to be beneficial to human health by acting as probiotics. Recent studies have shown that LAB and their extracts have beneficial effects on maintenance and improvement of skin health. Oral administration of Lactobacillus delbrueckii inhibits the development of atopic disease. In addition, LAB and LAB extracts are known to have beneficial effects on intestinal diseases, with Lactobacillus plantarum having been shown to attenuate IL-10 deficient colitis. In addition to intestinal health, L. plantarum also has beneficial effects on skin. pLTA, which is lipoteichoic acid isolated from L. plantarum, has anti-photoaging effects on human skin cells by regulating the expression matrix meralloprotionase-1 (MMP-1) expression. While several studies have proposed a relationship between diseases of the skin and small intestines, there are currently no published reviews of the effects of LAB for skin health through regulation of intestinal conditions and the immune system. In this review, we discuss recent findings on the effects of LAB on skin health and its potential applications in beauty foods.
