A Whole-Grain–Rich Diet Reduces Urinary Excretion of Markers of Protein Catabolism and Gut Microbiota Metabolism in Healthy Men after One Week

submitted by: Alastair Ross
Epidemiological studies consistently find that diets rich in whole-grain (WG) cereals lead to decreased risk of disease compared with refined grain (RG)-based diets. Aside from a greater amount of fiber and micronutrients, possible mechanisms for why WGs may be beneficial for health remain speculative. In an exploratory, randomized, researcherblinded, crossover trial, we measured metabolic profile differences between healthy participants eating a diet based on WGs compared with a diet...

Consumer attitudes and understanding of low sodium claims on food: An analysis of healthy and hypertensive individuals

submitted by: Christina.L.Wong
Background: Sodium-related claims on food labels should facilitate lower-sodium food choices; however, consumer attitudes and understanding of such claims are unknown. Objectives: We evaluated consumer attitudes and understanding of different types of sodium claims and the effect of having hypertension on responses to such claims. Design: Canadian consumers (n = 506), with and without hypertension, completed an online survey that contained a randomized mock package experiment, which...

Grape Powder Supplementation Prevents Oxidative Stress–Induced Anxiety-Like Behavior, Memory Impairment, and High Blood Pressure in Rats

submitted by: ssalim
We examined whether or not grape powder treatment ameliorates oxidative stress–induced anxiety-like behavior, memory impairment, and hypertension in rats. Oxidative stress in Sprague-Dawley rats was produced by using L-buthionine- (S,R)-sulfoximine (BSO). Four groups of rats were used: 1) control (C; injected with vehicle and provided with tap water), 2) grape powder–treated (GP; injected with vehicle and provided for 3 wk with 15 g/L grape powder dissolved in tap water), 3)...

Low folate status enhances pregnancy changes in plasma betaine and dimethylglycine concentrations and the association between betaine and homocysteine

submitted by: Michelle Murphy
ABSTRACT Background: Folate, choline, and betaine participate in homocysteine metabolism. It is not known whether they interact during pregnancy. Objective: The objective was to investigate how folate status affects choline, betaine, and dimethylglycine during pregnancy. Design: Fasting plasma folate, cobalamin, free choline, betaine, dimethylglycine, and total homocysteine (tHcy) were measured longitudinally at ,12, 15, 24–27, and 34 gestational weeks (GW); at labor (nonfasting);...

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...
