The prevalence of central obesity is constantly increasing, and visceral fat is associated with increased production of inflammatory factors and metabolic risk factors. Lutein might retard the development of metabolic disease through its antioxidant and anti-inflammatory properties. The influence of dietary lutein, with and without moderate amounts of vitamin C (VC) or vitamin E (VE), on biomarkers of oxidative stress was examined in rats. Nine groups of immature Zucker obese (fa/fa) and lean female rats (8/group) consumed ad libitum for 8 wk the AIN-93G diet (Control) to which
Age-related macular degeneration (AMD) is a major cause of visual impairment in the United States. Currently there is no effective cure for this disease. Risk factors include decreased lutein and zeaxanthin status and obesity. Obesity is also an increasing public health concern. The alarming
BACKGROUND
Several studies associated high-fat intakes with a high incidence of age-related macular degeneration (AMD). Lutein and Zeaxanthin isomers (L/Zi) may counteract reactive oxygen species produced by oxidative stress. The present study was conducted to determine the possible effects of L/Zi
BACKGROUND
Carotenoids as biologically active compounds, found in products of plant origin, have a beneficial impact on human health by protecting it against the development of many diseases. People and animals do not have the ability to synthesize these compounds de novo, they must be regularly
Assessing dietary intake in children is difficult and limited validated tools exist. Plasma carotenoids are nutritional biomarkers of fruit and vegetable intake and therefore suitable to validate reported dietary intakes. The aim of this study was to examine the comparative validity of a food
BACKGROUND
Obesity constitutes a growing health problem, and surgical treatment of severe obesity is increasingly used. Nutrient deficiencies are common following bariatric surgery and the evidence indicates a progressive increase in the incidence and severity of the deficiency of certain vitamins
OBJECTIVE
This study was performed to evaluate the effects of high vegetable-fruit (high-VF) and low vegetable-fruit (low-VF) diet on surrogate biomarkers of adiposity-related metabolic disturbances.
METHODS
Overweight women (n=22, 19-29 years) participated in the study between July and August, 2007
Carotenoid and vitamin C intakes, assessed by FFQ, have been positively associated with plasma concentrations in different populations. However, the influence of BMI on these associations has not been explored in detail. We explored in a cross-sectional study the relation between dietary carotenoid
SCOPE
Macular accumulation of
xanthophyll carotenoids (
lutein, zeaxanthin) is known to have neuroprotective potential, yet their influence on cognition among
overweight adults and those with
obesity remains limited. This study examines the impact of macular
xanthophylls on
METHODS
The aim of this study is to investigate whether AMP-activated protein kinase α2 (AMPKα2) is essential for wolfberry's protective effects on mitochondrial dysfunction and subsequent hepatic steatosis in mice.
RESULTS
Six-week-old male AMPKα2 knockout mice and genetic background C57BL/6J (B6)
The objective of this project was to investigate the relationships between total and regional distribution of body fat and tissue lutein (L) and zeaxanthin (Z) status. Healthy men and women (N = 100; average age: 22.5 year, average BMI: 23.4 kg/m2) were evaluated. Total body and regional fat mass
A study was made of the functional state of the gonads in 365 obese women. Clinical data were compared with the results of study of fractional composition of estrogens excreted with the urine at various phases of the menstrual cycle. Gonad dysfunction was much more frequent in neuro-endocrine than
Fucoxanthin, a xanthophyll present in brown algae consumed in Eastern Asia, can suppress carcinogenesis and obesity in rodents. We investigated the metabolism, tissue distribution, and depletion of fucoxanthin in ICR mice by comparison with those of lutein. The experiments comprised 14-d dietary
BACKGROUND
Carbohydrate restricted diets (CRD) consistently lower glucose and insulin levels and improve atherogenic dyslipidemia [decreasing triglycerides and increasing HDL cholesterol (HDL-C)]. We have previously shown that male subjects following a CRD experienced significant increases in HDL-C
