Effects of total fat intake on body fatness in adults.

Background: The ideal proportion of energy from fat in our food and its relation to body weight is not clear. In order to prevent overweight and obesity in the general population, we need to understand the relationship between the proportion of energy from fat and resulting weight and body fatness in the general population.

Objectives: To assess the effects of proportion of energy intake from fat on measures of body fatness (including body weight, waist circumference, percentage body fat and body mass index) in people not aiming to lose weight, using all appropriate randomised controlled trials (RCTs) of at least six months duration.

Device-Measured Sedentary Behavior Patterns in Office-Based University Employees.

Objective: The aim of this study was to describe device-measured patterns of sedentary behavior in self-identified sedentary university employees.

Methods: Participants (n = 78) wore the ActiGraph GT3X+ and the activPAL3 for 7 days. Data from the ActiGraph were used to identify time in sedentary behavior, light-intensity, and moderate-to-vigorous physical activity.

The Acute Metabolic and Vascular Impact of Interrupting Prolonged Sitting: A Systematic Review and Meta-Analysis.

Objective: The aim was to conduct a systematic review and meta-analysis analyzing the impact of up to 24 h of prolonged sitting on postprandial glucose, insulin and triglyceride responses, blood pressure and vascular function, in comparison to sitting interrupted with light- to moderate-intensity physical activity.

Methods: To be included, studies had to examine the impact of prolonged sitting lasting < 24 h in apparently healthy males or females of any age. Studies were identified from searches of the MEDLINE, CINAHL and SportDISCUS databases on July 6, 2016.

Effect of supplementation with flaxseed oil and different doses of fish oil for 2 weeks on plasma phosphatidylcholine fatty acids in young women.

Background/objectives: Although assumed, it remains unclear that fatty acid (FA) biomarkers of n-3 long-chain PUFA reflect wide ranges of intake. However, to be utilised as biomarkers, to predict dietary intake, dose-response curves that cover a spectrum of intakes are required. The aim of the study was to investigate whether the FA composition of plasma phosphatidylcholine (PC) is a sensitive biomarker of n-3 FAs from fish oil, across a range of supplementation doses, and alpha-linolenic acid (ALA) supplementation, in young, healthy women.

Red Meat Consumption and Serum Lipids and Fatty Acids in Toddlers: Secondary Outcomes of a Randomized Controlled Trial.

The aim of the study was to examine the effects of promoting increased lean red meat consumption on serum concentrations of total and high-density lipoprotein (HDL) cholesterol, and serum fatty acid composition, among toddlers. In a 20-week randomized controlled trial healthy 12 to 20-month-old children were assigned to: red meat (n = 90; parents were encouraged to add 56 g/day of lean red meat to their toddler's usual diet), or control (n = 90) groups. Food and nutrient intakes were assessed with 3-day weighed food records (baseline, week 4, and week 20).
