2. Effects of The Dietary Supplementation of Layer Diets with Natural and Synthetic Antioxidant Additives on Yolk Lipid Peroxidation and Fatty Acid Composition of Eggs Stored at Different Temperatures and Duration
ABSTRACT In this study, the effects of the supplementation of natural and synthetic antioxidant additives in layer diets on egg weight loss, yolk lipid peroxidation (TBARS values) and fatty acid composition of eggs stored at different temperatures and duration were evaluated. In total, 112 48- weeks-old Bovans White layers were randomly allotted to four diet

3. Effect of Dietary Curcumin on the Antioxidant Status of Laying Hens under High-Temperature Conditions
ABSTRACT Heat stress induces oxidative stress, and reduces body antioxidant metabolite levels, which can affect poultry production performance. Dietary antioxidants protect birds against the adverse effects of heat stress. The effects of increasing concentrations of dietary curcumin on the antioxidant parameters of layers maintained under high-temperature co

4. Effects of curcumin on cardiovascular risk factors in obese and overweight adolescent girls: a randomized clinical trial
ABSTRACT BACKGROUND: Obese adolescents are at higher risk of development of cardiovascular risk factors and obesity in later life. Dietary intake of antioxidants, particularly curcumin, as an active ingredient of turmeric extract, may have noticeable effects on obesity and its important complications such as cardiovascular risk factors. Therefore, the aim

6. Dietary Effects of Natural Polyphenol Antioxidant on Laying Performance and Egg Quality of Laying Hens Fed Diets with Oxidized Oil
ABSTRACT This study was conducted to investigate the effects of dietary oxidized oil and natural polyphenol antioxidants on laying performances and egg quality of laying hens. A total of two hundred, 61-week-old Lohmann Brown laying hens were divided into five groups, consisting in four replicates of 10 birds each. They were fed one of the five experimental

8. Lipid oxidation in meat: mechanisms and protective factors – a review
Abstract Lipid oxidation in meats is a process whereby polyunsaturated fatty acid react with reactive oxygen species leading to a series of secondary reactions which in turn lead to degradation of lipids and development of oxidative rancidity. This process is one of the major factors responsible for the gradual reduction of sensory and nutritional quality o

9. Factors that influence the redox state in children: An exploratory study
OBJECTIVE: The aim of the present study was to investigate the association of the redox state via malondialdehyde (MDA) as a lipid peroxidation biomarker and hydrophilic antioxidant capacity (HAC) with dietary, anthropometric, demographic, socio-economic and clinical variables as well as the serum concentrations of vitamins in children aged 20-36 months. Th

10. Nutritional and antioxidant potential of a desert underutilized legume – tepary bean (Phaseolus acutifolius). Optimization of germination bioprocess
Abstract Tepary bean (Phaseolus acutifolius) is a short life cycle legume, resistant to many diseases and drought, originally from the deserts and semi-arid environment of Northwestern Mexico and the Southwestern US. Its mature seeds are scarce consumed, and their high protein and carbohydrate contents are underutilized. The aim was to identify optimal germ

12. Study on the Efficiency of Grape Seed Meals Used as Antioxidants in Layer Diets Enriched with Polyunsaturated Fatty Acids Compared with Vitamin E
ABSTRACT The 4-week study was conducted with 180 Lohmann Brown layers (52 weeks of age). The layers were assigned to three groups (C, E1 and E2). The basal diet (group C) consisted mainly of corn, soybean meal and corn gluten, and contained 19% crude protein and 11.58 MJ/kg metabolizable energy. The diets for groups E1 and E2 differed from group C by the inc
