In this study, healthy women and those at high-risk of adverse pregnancy outcomes (pre-eclampsia, fetal growth restriction, gestational diabetes) were selected to assess the effect of fatty acid supplementation. The purpose of this paper is to report two novel findings (i) at recruitment the receiver operating characteristic (ROC) for erythrocyte oleic acid predicted spontaneous delivery at 34 weeks gestation (ROC=0.926 n=296) for all women entering the study. Further analysis revealed oleic and all monounsaturated fatty acids were similarly predictive with or without a supplement during the pregnancy...

REVIEW
Vargas-Bello-Pérez E, Larraín R E
In the last decades there has been an increased consumer interest in the fatty acid (FA) composition of ruminant meat due to its content of saturated FA, which have been implicated in diseases associated with modern life. However, recent studies have questioned the recommendations to reduce intake of fat, saturated FA and cholesterol as a mean of reducing risk of cardiovascular disease. Interestingly, ruminant meat has some bioactive lipids such as C18:1t11 and C18:2 c9, t11 which have been reported to have positive effects on human health...

OBJECTIVES: Food insecurity, defined as the limited or uncertain availability of nutritious and safe foods, is a complex phenomenon and is linked to poor nutrition and diet-sensitive chronic diseases. Dietary patterns that include saturated fats and meat products are potential risk factors for the progression of peripheral arterial disease (PAD). This study explored whether there is a relationship between food insecurity and PAD among a national sample of older adults. DESIGN: We conducted a cross-sectional data analysis using data from the 1999-2004 National Health and Nutrition Examination Survey (NHANES)...

The diabetic diet is one of the pillars of diabetes treatment. The rapid development of knowledge relating to the treatment of diabetes also includes diet. The paper focuses on the importance of a diet in the treatment of type 2 diabetes and prevention of atherosclerosis. Its main goal is to assess the impact of a composition of macronutrients on individuals with type 2 diabetes. The paper is divided into several parts, each of which ends with a conclusion. The first part examines weight reduction. The diet aimed at a weight loss is effective, it can effectively prevent diabetes, it leads to improvements in glucose control and reduction of the risk factors for atherosclerosis, however it will not impact on cardiovascular morbidity and mortality until after more than 20 years...

Macrophages play a critical role in obesity-associated chronic inflammation and disorders. However, the molecular mechanisms underlying the response of macrophages to elevated fatty acids (FAs) and their contribution to metabolic inflammation in obesity remain to be fully elucidated. In this article, we report a new mechanism by which dietary FAs, in particular, saturated FAs (sFAs), are able to directly trigger macrophage cell death. We demonstrated that excess sFAs, but not unsaturated FAs, induced the production of cytotoxic ceramides (Cers) in macrophage cell lines...

Shift work has been associated with dietary changes. This study examined factors associated with the dietary profiles of shift workers from several industries (n = 118, 57 male; age = 43.4 ± 9.9 years) employed on permanent mornings, nights, or rotating 8-h or 12-h shifts. The dietary profile was assessed using a Food Frequency Questionnaire. Shift-related (e.g., sleep duration and fatigue), work-related (e.g., industry), and demographic factors (e.g., BMI) were measured using a modified version of the Standard Shift work Index...

Mass produced plastic syringes may be applied as vessels for cheap, simple and large scale batch culture testing. As illustrated for the cases of denitrification and of biogas formation, metabolic activity was monitored by direct reading of the piston movement due to the gas volume formed. Pressure buildup due to friction was shown to be moderate. A piston pull and slide back routine can be applied before recording gas volume to minimize experimental errors due to friction. Inoculum handling and activity may be conveniently standardized as illustrated by applying biofilm carriers...

OBJECTIVE: Hyperinsulinemia is a prevalent feature of polycystic ovary syndrome (PCOS), contributing to metabolic and reproductive manifestations of the syndrome. Weight loss reduces hyperinsulinemia but weight regain is the norm, thus preventing long-term benefits. In the absence of weight loss, replacement of dietary carbohydrate (CHO) with mono/polyunsaturated fat reduces ambient insulin concentrations in non-PCOS subjects. The current study evaluated whether this dietary intervention could ameliorate hyperinsulinemia in women with PCOS...

Many studies have investigated the effect of crude tomato peel in vivo, but no studies have determined the dose-effect of dry tomato peel (DTP) on glucose intolerance, insulin resistance, and atherogenic dyslipidemia induced by a high-saturated-fat (HSF) diet in vivo. The aim of this study was to investigate the effects of different doses of DTP on the levels of oxidative stress in mice fed an HSF and cholesterol-rich diet for 12 weeks. The main outcomes are glucose and insulin tolerance, plasma lipids, and hepatic steatosis and inflammation...

The brain is highly enriched in lipids, where they influence neurotransmission, synaptic plasticity and inflammation. Non-pathological modulation of the brain lipidome has not been previously reported and few studies have investigated the interplay between plasma lipid homeostasis relative to cerebral lipids. This study explored whether changes in plasma lipids induced by chronic consumption of a well-tolerated diet enriched in saturated fatty acids (SFA) was associated with parallel changes in cerebral lipid homeostasis...

The objective of this study was to examine the effects of Tithonia diversifolia as a supplementary forage on dairy cow performance and methane production. Nine lactating Holstein × Zebu dairy cows (519 ± 53.3 kg of body weight and 66 ± 13.3 d in milk) were paired by milk yield (21.3 ± 2.34 kg/d) and body weight and randomly assigned to three dietary treatments in a Latin square design with 21-d experimental periods (14 d for diet adaptation and 7 d for measurements and sample collection). The dietary treatments included the control diet consisting of fresh sugar cane plus concentrate (44:56, % of diet DM), and two treatment diets containing different levels of fresh T...

PURPOSE OF REVIEW: Dairy is a major food group with potential impact on cardiometabolic health. Self-reported dairy intake has limitations that can partly be avoided by using biomarkers. This review aims to summarize the evidence of odd-chain saturated fatty acids (OCFAs), that is, pentadecanoic acid (C15 : 0) and heptadecanoic acid (17 : 0), as biomarkers of dairy fat intake. In addition, the associations of OCFA biomarkers with cardiometabolic disease will be overviewed. RECENT FINDINGS: Adipose tissue 15 : 0 is the preferred biomarker but also circulating 15 : 0, and to a weaker extent 17 : 0, reflects both habitual and changes in dairy intake...

Cell proliferation and neuroinflammation in the adult hypothalamus may contribute to the pathogenesis of obesity. Here we tested whether the intertwining of these two processes has a role in the metabolic changes caused by three weeks of saturated high-fat diet (HFD) consumption.As compared to chow, HFD-fed mice rapidly increased body weight and fat mass, and specifically showed increased microglia number in the arcuate nucleus (ARC) of the hypothalamus. Microglia expansion required the adequate presence of fats and carbohydrates in the diet, since feeding mice a very high-fat, very low-carbohydrate diet did not affect cell proliferation...

BACKGROUND: Different aspects of dietary pattern, including macronutrient and food profiles, may affect visceral fat mass and metabolic syndrome. OBJECTIVE: We hypothesized that consuming energy primarily from carbohydrate or fat in diets with similar food profiles would differentially affect the ability to reverse visceral adiposity and metabolic syndrome. DESIGN: Forty-six men (aged 30-50 y) with body mass index (in kg/m(2)) >29 and waist circumference >98 cm were randomly assigned to a very high-fat, low-carbohydrate (VHFLC; 73% of energy fat and 10% of energy carbohydrate) or low-fat, high-carbohydrate (LFHC; 30% of energy fat and 53% of energy carbohydrate) diet for 12 wk...

Change of muscle tissue oxygen saturation (StO2), due to exercise, measured by near infrared spectroscopy (NIRS) is known to be lower for subjects with higher adipose tissue thickness. This is most likely not physiological but caused by the superficial fat and adipose tissue. In this paper we assessed, in vitro, the influence of adipose tissue thickness on muscle StO2, measured by NIRS oximeters. We measured StO2 of a liquid phantom by 3 continuous wave (CW) oximeters (Sensmart Model X-100 Universal Oximetry System, INVOS 5100C, and OxyPrem v1...
