Frequent Consumption of Selenium-Enriched Chicken Meat by Adults Causes Weight Loss and Maintains Their Antioxidant Status

Abstract

To assess the effects of a moderately high-protein intake on the body composition, biochemical, and antioxidant status parameters in young adults depending on either selenium- (Se) or non-enriched chicken consumption. The volunteers (n = 24) that completed the 10-week nutritional intervention were distributed in two parallel groups and randomly assigned to follow an isocaloric diet with moderately high content in protein (30% energy), either with the consumption of four 200 g portions/week of Se- or non-enriched chicken breasts. Blood samples were taken at the beginning and at the end of the study and body composition was monitored during the trial. There was a significant reduction in weight, accompanying a decrease on fat mass in both groups, while fat-free mass remained unchanged during the 10 weeks of intervention, without differences between both dietary groups. Selenium blood levels and plasma glutathione peroxidase activity, as well as lipid, glucose, and selected inflammation biomarkers remained stable during the intervention period in both dietary groups. Frequent chicken consumption, within a controlled diet with a moderately high content in protein, produced a slight but statistically significant weight reduction mainly due to the loss of fat mass. An extra Se supplementation (22 μg/day) in the Se-enriched chicken breast did not affect tachyphylactic antioxidant status of the participants neither inflammatory-related markers after weight loss.

Different postprandial acute response in healthy subjects to three strawberry jams varying in carbohydrate and antioxidant content: a randomized, crossover trial

“…Regarding these outcomes, there are controversial opinions. Some authors have reported that after the consumption of antioxidant products by subjects with an optimal antioxidant status, no differences or improvements have been observed [37][38][39]. However, in subjects with low antioxidant status, beneficial effects have been shown [40,9].…”

Chronologically scheduled snacking with high-protein products within the habitual diet in type-2 diabetes patients leads to a fat mass loss: a longitudinal study

“…Indeed, some long-term studies with no calorie restriction and programmed macronutrient distribution have resulted in a more effective weight loss and maintenance than conventional macronutrient distribution energy-restricted diets [11,30,31]. In a recent study, an isocaloric diet with a moderately high content in protein led to a body weight and fat mass reduction after 10 weeks [26], without affecting fat-free mass and maintaining glucose and lipid profile, which matches with the outcomes of the current intervention.…”

Selenium in Soil-Crop-Animal System: A Holistic Perspective to Manage Animal and Human Health

“…The SeMet containing plant or yeast protein consumed by animals can be also stored in animal protein, which can result in bioactive selenium content in meat, milk, and eggs with potential human health benefits. As a result, supplementation of animal diets with selenium yeast contributed to the development of selenium-rich functional foods, including selenium-enriched milk, eggs and meats for human consumption [49][50][51][52]. Pure selenomethionine is also known as a toxic substance.…”
