Association of raw fruit and fruit juice consumption with blood pressure: the INTERMAP Study

submitted by: loudegri
Background: Epidemiological evidence suggests that fruit consumption may lower the risk of cardiovascular diseases through blood pressure (BP)–lowering effects; little is known on the independent effect of raw fruit and fruit juice on BP. Objective: The objective was to quantify associations of raw fruit and fruit juice consumption with BP by using cross-sectional data from the INTERnational study on MAcro/micronutrients and blood Pressure (INTERMAP) of 4680 men and women aged...

Weight loss, weight maintenance, and adaptive thermogenesis

submitted by: stefancamps
Background: Diet-induced weight loss is accompanied by adaptive thermogenesis, ie, a disproportional or greater than expected reduction of resting metabolic rate (RMR). Objective: The aim of this study was to investigate whether adaptive thermogenesis is sustained during weight maintenance after weight loss. Design: Subjects were 22 men and 69 women [mean 6 SD age: 40 6 9 y; body mass index (BMI; in kg/m2): 31.9 6 3.0]. They followed a very-low-energy diet for 8 wk, followed by a...

Fruit, Mediterranean-style, and high-fat and -sugar diets are associated with the risk of night sweats and hot flushes in midlife

submitted by: gcmherber
Background: Diet has been suggested to be a potential risk factor for vasomotor menopausal symptoms (VMS), i.e. hot flushes and night sweats. Objective: We investigated the associations between dietary patterns and risk of VMS using data from mid-aged women born between 1946 and 1951 in the Australian Longitudinal Study on Women’s Health. Design: A prospective cohort study of 6,040 women with a natural menopause, who were followed up at three-year intervals over nine years. Dietary...

A magnetic resonance spectroscopy technique to determine the stomach emptying rate of mixed diets in growing rats

submitted by: cmontoya
A rapid technique allowing the accurate determination of stomach emptying rate (SER) would be useful for understanding the process of digestion. The development of a rapid magnetic resonance spectroscopy (MRS) technique based on the marker AlCl3-6H2O, (Al-MRS), to determine the real-time SER of foods in a rat model is described. Experiments were conducted to establish several parameters for the Al-MRS technique and to validate the technique against the traditional serial slaughter method....

High nutritional quality is not associated with low greenhouse gas emissions in self-selected diets of French adults

submitted by: Nicole Darmon
Background: Healthy diets are supposed to be more environmentally friendly because they rely mainly on plant-based foods, which have lower greenhouse gas emissions (GHGEs) per unit weight than do animal-based foods. Objectives: The objectives were to estimate the GHGEs associated with the consumption of self-selected diets in France and to analyze their relation with the nutritional quality of diets. Design: For each adult in the national dietary Individual and National Survey on Food...

Dietary Selenium Deficiency Partially Rescues Type 2 Diabetes–Like Phenotypes of Glutathione Peroxidase-1–Overexpressing Male Mice

submitted by: xlei
This study was conducted to determine whether dietary Se deficiency precluded overproduction of glutathione peroxidase-1 (GPX1) activity in mice overexpressing (OE) this gene and thus rescued their type 2 diabetes–like phenotypes. A total of 20 male OE and wild-type (WT) mice were fed an Se-deficient (<0.02 mg/kg) diet or an Se-supplemented (0.3 mg/kg as sodium selenite) diet from 1 to 5 mo of age. Dietary Se deficiency eliminated or attenuated (P < 0.05) genotype differences in...

Social Media Delivered Sexual Health Intervention: A Cluster Randomized Controlled Trial

submitted by: sheana
Design: Cluster randomized trial; data collected in 2010-2011; analyzed in 2011-2012 Setting/Participants: Individuals (seeds) recruited in multiple settings (online, via newspaper ads and face-to-face) who were asked to recruit up to three friends, who in turn recruited additional friends, extending three waves from the seed. Seeds and waves of friends were considered networks and exposed to either intervention or control condition. Intervention: Exposure to Just/Us, a Facebook page...

Diet composition is associated with endogenous formation of N-nitroso compounds in obese men

submitted by: silviagratz
Endogenous formation of carcinogenic N-nitroso compounds (NOC) occurs in the human gut. Red meat is considered the most important dietary component linked to NOC formation, although nitrate and vitamin C (VitC) also contribute. We previously showed that high-protein weight-loss diets increased fecal NOC and this was enhanced by simultaneous carbohydrate restriction. Although previous studies have focused on the effect of either 1 or 2 dietary components on endogenous NOC formation, no...

Prepregnancy adherence to dietary patterns and lower risk of gestational diabetes mellitus

submitted by: dtobias
Abstract BACKGROUND: Previous studies observed inverse associations of adherence to the alternate Mediterranean (aMED), Dietary Approaches to Stop Hypertension (DASH), and alternate Healthy Eating Index (aHEI) dietary patterns with risk of type 2 diabetes; however, their associations with gestational diabetes mellitus (GDM) risk are unknown. OBJECTIVE: This study aimed to assess usual prepregnancy adherence to well-known dietary patterns and GDM risk. DESIGN: Our study included 21,376...

Science Nation - If These Teeth Could Talk

submitted by: nsf
With funding from the National Science Foundation, Peter Ungar is revealing more details about the lives of our human ancestors, and he's doing it through dentistry - sort of! The University of Arkansas anthropologist uses high tech dental scans to find out more about the diets of hominids, a technique that sometimes leads to new and very different conclusions. While anthropologists traditionally determine the diets of our ancestors by examining the size and shape of teeth and jaws, Ungar's...
