Trastornos de la conducta alimentaria en el embarazo / Eating disorders in pregnancy

Los trastornos de la conducta alimentaria afectan a mujeres en edad fértil, sin embargo, la intersección de éstos y el embarazo es aún pobremente comprendida, existiendo aún datos limitados en la literatura. Esta revisión narrativa resume la evidencia actual acerca de los trastornos alimentarios durante el embarazo: su prevalencia, curso, el impacto que éstos tienen en la salud materna, fetal y en su descendencia, así como posibles estrategias de intervención.

Eating disorders affect women of childbearing age, however, their intersection with pregnancy is still poorly understood, while there is still limited data in the literature. This narrative review summarizes the current evidence about eating disorders during pregnancy: their prevalence, course, the impact they have on maternal, fetal and offspring health, as well as possible intervention strategies.

The Consumption of Beef Burgers Prepared with Wine Grape Pomace Flour Improves Fasting Glucose, Plasma Antioxidant Levels, and Oxidative Damage Markers in Humans: A Controlled Trial.

Wine grape pomace flour (WGPF) is a fruit byproduct that is high in fiber and antioxidants. We tested whether WGPF consumption could affect blood biochemical parameters, including oxidative stress biomarkers. In a three-month intervention study, 27 male volunteers, each with some components of metabolic syndrome, consumed a beef burger supplemented with 7% WGPF containing 3.5% of fiber and 1.2 mg gallic equivalents (GE)/g of polyphenols (WGPF-burger), daily, during the first month. The volunteers consumed no burgers in the second month, and one control-burger daily in the third month. At baseline and after these periods, we evaluated the metabolic syndrome components, plasma antioxidant status (i.e., 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity (DPPH), vitamin E, vitamin C), and oxidative damage markers (i.e., advanced oxidation protein products (AOPPs), oxidized low-density lipoproteins (oxLDLs), malondialdehyde (MDA)). The WGPF-burger intake significantly reduced glycemia and homeostatic model assessment-based measurement of insulin resistance. Vitamin C increased and decreased during the consumption of the WGPF-burger and control-burger, respectively. The WGPF-burger intake significantly decreased AOPP and oxLDL levels. Vitamin E and MDA levels showed no significant changes. In conclusion, the consumption of beef burgers prepared with WGPF improved fasting glucose and insulin resistance, plasma antioxidant levels, and oxidative damage markers. Therefore, this functional ingredient has potential as a dietary supplement to manage chronic disease risk in humans.
