BACKGROUND: Evidence on the association between dietary patterns, measures of hip bone geometry, and subsequent fracture risk are scarce. OBJECTIVE: The objective of this study was to evaluate whether dietary patterns that explain most variation in bone mineral density (BMD) and hip bone geometry are associated with fracture risk. DESIGN: We included 4028 subjects aged ≥55 y from the Rotterdam study. Intake of 28 food groups was assessed with the use of food-frequency questionnaires...

BACKGROUND: Water, an essential nutrient, is believed to be related to a variety of health outcomes. Published studies have examined the association of fluid or beverage intake with risk of mortality from coronary diseases, diabetes, or cancer, but few studies have examined the association of total water intake with all-cause mortality. OBJECTIVE: We examined prospective risk of mortality from all causes in relation to intakes of total water and each of the 3 water sources...

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...

BACKGROUND: Animal studies have shown that a high intake of galactose, a breakdown product of lactose, increases ovarian toxicity. Few epidemiologic studies, to our knowledge, have examined the association between dairy intake and fertility, and they have had conflicting findings. OBJECTIVE: We prospectively evaluated dairy intake in relation to fecundability among women who were planning for pregnancy. DESIGN: Data were derived from preconception cohort studies in Denmark (Snart Foraeldre) and North America [PRESTO (Pregnancy Study Online)] in which women completed a validated food-frequency questionnaire 10 d after enrollment...

BACKGROUND: Muscle mass maintenance is largely regulated by basal muscle protein synthesis rates and the ability to increase muscle protein synthesis after protein ingestion. To our knowledge, no previous studies have evaluated the impact of habituation to either low protein intake (LOW PRO) or high protein intake (HIGH PRO) on the postprandial muscle protein synthetic response. OBJECTIVE: We assessed the impact of LOW PRO compared with HIGH PRO on basal and postprandial muscle protein synthesis rates after the ingestion of 25 g whey protein...

BACKGROUND: An understudied component of the diet, branched-chain fatty acids (BCFAs) are distinctive saturated fatty acids that may have an important influence on health. Human-milk fatty acid composition is known to differ worldwide, but comparative data are lacking on BCFAs. OBJECTIVE: We tested the hypotheses that concentrations of BCFAs in human milk differ between populations and are associated with maternal diet. DESIGN: We surveyed the BCFA composition of samples collected as part of a standardized, prospective study of human-milk composition...

BACKGROUND: Many trials assessing effects of dietary weight loss on vascular function have been performed without no-weight loss control groups and in individuals with obesity-related morbidities. Usually a limited set of vascular function markers has been investigated. OBJECTIVE: The objective of this study was to examine effects of diet-induced weight loss on various vascular function markers and differences between normal-weight and abdominally obese men at baseline and after weight reduction...

BACKGROUND: Observational associations between red meat intake and cardiovascular disease (CVD) are inconsistent. There are limited comprehensive analyses of randomized controlled trials (RCTs) that investigate the effects of red meat consumption on CVD risk factors. OBJECTIVE: The purpose of this systematically searched meta-analysis was to assess the effects of consuming ≥0.5 or <0.5 servings of total red meat/d on CVD risk factors [blood total cholesterol (TC), LDL cholesterol, HDL cholesterol, triglycerides, ratio of TC to HDL cholesterol (TC:HDL), and systolic and diastolic blood pressures (SBP and DBP, respectively)]...

BACKGROUND: Large portions of food promote intake, but the mechanisms that drive this effect are unclear. Previous neuroimaging studies have identified the brain-reward and decision-making systems that are involved in the response to the energy density (ED) (kilocalories per gram) of foods, but few studies have examined the brain response to the food portion size (PS). OBJECTIVE: We used functional MRI (fMRI) to determine the brain response to food images that differed in PSs (large and small) and ED (high and low)...

BACKGROUND: Telomere length and telomere shortening are associated with age-related health outcomes. Only a few studies have been able to longitudinally report on factors that are associated with changes in telomere length in an aging population. OBJECTIVE: We studied the longitudinal relation between telomere length, the change in telomere length, and circulating amino acids. DESIGN: A total of 812 subjects from the Helsinki Birth Cohort Study (born from 1934 to 1944), who underwent 3 clinical visits during a 10-y interval that included measurements of cardiometabolic risk factors, were included in the study...

REVIEW
Aedín Cassidy, Anne-Marie Minihane
At a population level, there is growing evidence of the beneficial effects of dietary flavonoids on health. However, there is extensive heterogeneity in the response to increased intake, which is likely mediated via wide interindividual variability in flavonoid absorption and metabolism. Flavonoids are extensively metabolized by phase I and phase II metabolism (which occur predominantly in the gastrointestinal tract and liver) and colonic microbial metabolism. A number of factors, including age, sex, and genotype, may affect these metabolic processes...

Xiao Gu, Katherine L Tucker
BACKGROUND: The state of the economy, changes in federal food assistance programs, and policies related to nutrition and the food supply in the United States may influence dietary quality in children and adolescents. OBJECTIVE: We investigated dietary quality trends from 1999 to 2012 in the US child and adolescent population and their associations with socioeconomic status and participation in federal food assistance programs. DESIGN: In this study, a nationally representative sample of 38,487 children and adolescents, aged 2-18 y, in the NHANES from 1999 to 2012 were included...

BACKGROUND: The effect of a weight-loss intervention on the masses of lean tissues and organs in humans is not well known. OBJECTIVE: We studied the effects of a diet and exercise weight-loss intervention on skeletal muscle (SM) mass and selected organs over 2 y using MRI in overweight adults with type 2 diabetes. DESIGN: Participants were 53 women and 39 men [mean ± SD: age 58 ± 7 y; body mass index (BMI; in kg/m(2)) 32 ± 3] enrolled in the Look AHEAD (Action for Health in Diabetes) trial and randomly assigned to an intensive lifestyle intervention (ILI) or diabetes support and education (DSE) on whom 2 y of data were collected...

BACKGROUND: Fortified cow milk is a material contributor of vitamin D and dietary fat in children. Recommendations for children >2 y of age advise reduced milk-fat consumption to reduce childhood obesity, yet the relation between lower milk fat, vitamin D stores, and body mass index (BMI) is unclear. OBJECTIVES: The primary objective was to explore the association between milk-fat percentage and both BMI z score (zBMI) and venous 25-hydroxyvitamin D [25(OH)D]; the secondary objective was to assess whether milk volume consumed modified this relation...

BACKGROUND: Resistance exercise increases muscle mass and function in older adults, but responses are attenuated compared with younger people. Data suggest that long-chain n-3 polyunsaturated fatty acids (PUFAs) may enhance adaptations to resistance exercise in older women. To our knowledge, this possibility has not been investigated in men. OBJECTIVE: We sought to determine the effects of long-chain n-3 PUFA supplementation on resistance exercise training-induced increases in muscle mass and function and whether these effects differ between older men and women...

BACKGROUND: It has been widely recognized that parental dietary intake is an important and consistent factor influencing children's food intake. However, there are conflicting results with regard to the strength of the parental-child resemblance in dietary intake. Moreover, this association has rarely been investigated in young adult offspring. OBJECTIVES: The aims of this study were to describe the dietary intake and food consumption of middle-aged women and their female and male adult offspring (aged 18-23 y) and to examine the association in dietary intake between sex-specific mother-child dyads...

Kelly W Sheppard, Carol L Cheatham
BACKGROUND: The ω-6 (n-6) to ω-3 (n-3) fatty acid (FA) ratio (n-6:n-3 ratio) was previously shown to be a predictor of executive function performance in children aged 7-9 y. OBJECTIVE: We aimed to replicate and extend previous findings by exploring the role of the n-6:n-3 ratio in executive function performance. We hypothesized that there would be an interaction between n-3 and the n-6:n-3 ratio, with children with low n-3 performing best with a low ratio, and those with high n-3 performing best with a high ratio...

BACKGROUND: Musculoskeletal injuries are the most common complaint in active populations. More than 50% of all injuries in sports can be classified as sprains, strains, ruptures, or breaks of musculoskeletal tissues. Nutritional and/or exercise interventions that increase collagen synthesis and strengthen these tissues could have an important effect on injury rates. OBJECTIVE: This study was designed to determine whether gelatin supplementation could increase collagen synthesis...
