Changes in Plasma Carotenoid Concentrations during the AntioxObesity Weight Reduction Program among Adults with Excessive Body Weight.

Plasma carotenoid concentrations are associated with antioxidant defense which might be disturbed in people with excessive body weight (EBW). This study aimed at evaluating the effect of a 6-week weight reduction program on plasma concentration of β-carotene, lycopene, and lutein/zeaxanthin in adults with EBW. A total of 130 adults were recruited for the study; 75 completed the program.

Intake of Saturated Fatty Acids Affects Atherogenic Blood Properties in Young, Caucasian, Overweight Women Even without Influencing Blood Cholesterol.

Despite a general relation between fat intake and cardiovascular risk factors, the association is often not observed in studies conducted in heterogenic populations, as for population groups, it may differ. The aim of the study was to analyze the associations between dietary fat intake and lipoprotein cholesterol fractions, as well as atherogenic blood properties, in young and middle-aged overweight Caucasian women. In a group of 138 overweight women, the three-day dietary records were assessed, under-reporters were excluded, and lipoprotein cholesterol fractions were analyzed.

Weight loss program is associated with decrease α-tocopherol status in obese adults.

Background & Aims: Studies on changes in plasma α-tocopherol levels during body fat reduction in obese persons are not clear. The aim of the present study was to assess factors associated with α-tocopherol status in obese people and to examine changes in α-tocopherol status after a 6-week AntioxObesity weight loss program.

Methods: The study was conducted in 60 overweight or obese adults, aged 18-54 years old.

Dietary sources of lutein in adults suffering eye disease (AMD/cataracts).

Background: Epidemiological studies indicate that by consuming 6-14 mg lutein daily, the risk of acquiring eye diseases like age-related macular degeneration (AMD) or cataracts becomes reduced. Their symptoms can also by such means be alleviated and treatment improved.

Objectives: To estimate dietary intakes of lutein obtained from foodstuffs and supplements along with determining its main sources in selected groups of adults suffering from eye disease and healthy controls.

Comparing diabetic with non-diabetic overweight subjects through assessing dietary intakes and key parameters of blood biochemistry and haematology.

Introduction: An important way of preventing type 2 diabetes is by adopting a proper diet by which means appropriate control over blood glycaemia and lipids can be achieved.

Objectives: To assess selected biochemical and haematological markers in overweight subjects or those suffering from type 2 diabetes in relation to their estimated dietary intake.

Material And Methods: The study was conducted in 2012 on n = 86 overweight or obese subjects living in Warsaw or its environs, of whom n = 43 had type 2 diabetes.

[The assessment of beta-carotene, lycopene and lutein intake selected group of adults].

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 supplied with food.

Objective: The aim of this study was to evaluate intake of selected carotenoids and indicate their main sources in the daily food ration in adults.
