NHANES 1999–2004 24‐hr dietary recall data were used to compare nutrient intake and diet quality (HEI‐2005) between highest lean/lowest fat (HLLF) beef consumers and lowest lean/highest fat (LLHF) beef consumers aged 4+ y (n = 11,507). Beef intakes were determined by summing amounts of beef contained in survey foods. The fat content of beef consumed was linked to the survey‐specific Nutrient Database for Standard Reference. Beef consumers were classified into tertile groups based on the fat content of beef consumed. HLLF beef consumers had higher protein intake; lower energy; total, saturated, and monounsaturated fat; and carbohydrate than LLHF beef consumers. HLLF beef consumers also had significantly higher intakes of vitamins A, C, B3, B6, B12; phosphorus; magnesium; iron; zinc; and potassium; and lower intake of calcium than LLHF beef consumers. Compared to the LLHF beef group, HLLF beef consumers also had higher cup equivalent intakes of total vegetables, dark green/orange vegetables, and legumes, higher meat oz equiv, lower grain oz equiv, lower milk cup equiv, and lower energy from solid fat and SoFAAS. Additionally, HLLF beef consumers had higher total HEI scores than LLHF beef consumers (51.0 ± 0.3 vs. 45.2 ± 0.3). Improved nutrient intake and diet quality were associated with consumption of lean beef. Support: USDA and Beef Checkoff

Nutrient intakes, mean adequacy ratios (MAR) (average percentage of the Estimated Average Requirement from 24 hour recalls of 13 vitamin and minerals), and weight of PSRTEC, NPSRTEC, and OB consumers were compared. Means + standard error were generated and regression analysis was performed adjusting for covariates. Breakfast varied by age: for 9‐13y vs. 14‐18y, 27% and 15% ate PSRTEC; 7% and 5% ate NPSRTEC, and 46% and 47% ate OB. Energy and total/added sugars were highest in PSRTEC; for 9‐13y total/added sugars were 30.6% and 21.4% of total energy and for 14‐18y total/added sugars were 29.9% and 21.1%, respectively. Total fat was lowest in 9‐13y NPSRTEC and 14‐18y PSRTEC consumers. Vitamins B6 & B12, thiamin, riboflavin, niacin, and folate were higher in RTEC than OB consumers. Calcium, potassium, magnesium, iron, and phosphorus were highest in NPSRTEC consumers compared to the two other groups. For both 9‐13y and 14‐18y, MAR was higher in RTEC than OB consumers. Body Mass Index (BMI) in OB was higher than that in NPSRTEC for both groups. Nutrient profiles vary depending on the type of breakfast consumed.

Many consumers are unfamiliar with dried beans or do not have the time to prepare them. The purpose of this study was to compare nutrient density and nutrient-to-cost among dried cooked, canned (liquid and solids), and canned/drained black, garbanzo, kidney, lima, pinto, white beans, and black-eyed peas. Prices were obtained from 60 grocery stores in January 2009. Nutrient content per 100 g was calculated using the U.S. Department of Agriculture Nutrient Database for Standard Reference, Release 22, and Nutrition Data System for Research (for canned/drained). Nutrient density scores were estimated using the Nutrient Rich Food Index 9.3 (NRF9.3). Nutrient-to-cost ratio (NTCR) was computed as the NRF 9.3 score (per 100 kcal) divided by the cost per half-cup servings per package (12) or per can (3.5). Compared to canned beans, dried cooked beans were significantly more energy dense, contained more protein, fiber, iron, potassium and magnesium; and less sodium than canned beans (p < 0.05 for all). Canned/drained beans contained more sodium than cooked beans (p < 0.05). NRF9.3 scores were 7.3, 2.8, and 4.8 for cooked, canned, and canned/drained beans, respectively. NTCR for cooked, canned, and canned/drained beans was 63.4, 8.9, and 15.2, respectively. Results highlight the benefits of choosing dried beans and also illustrate that canned beans, when drained, provide a healthy alternative. Beans, regardless of type/form, are a nutrient rich food and should be encouraged as part of an overall healthy diet.

Fifty‐eight Caucasian females 19–24 years of age participated. Subjects completed three scans of the right heel using a GE Lunar Achilles InSight QUS machine; a semi‐quantitative modified Block food frequency questionnaire (FFQ) with approximately 105 items; ten questions regarding restrained eating (RE); the International Physical Activity Questionnaire (IPAQ) short form; a health history form; and were measured for height and weight. Factor analysis was used to determine relationships between variables. QUS scores factored with RE and weight; height was related to fiber; and neither total energy (kcal) nor PA were related to QUS or RE. Further research is needed with more sensitive bone markers and a larger sample size to determine the relationship of bone quality with diet, PA, and eating be...

This study examined if bone quality was associated with calcium (Ca) intake, restrained eating and physical activity in a group of 99 young adult women. Caucasian volunteers, 20–29 years of age completed a Block Food Frequency Questionnaire, Dutch Eating Behavior Questionnaire (DEBQ) and the International Physical Activity Questionnaire. Heights and weights were measured using standard procedures, and calcaneus stiffness index (SI) scores were recorded using an Achilles Insight GE quantitative ultrasound. Participants had a mean ± SD age, height, weight, BMI, bone quality, restrained eating and physical activity of 21.5 ± 1.7 yrs, 164.0 ± 6.4 cm, 61.4 ± 9.2 kg, 22.8 ± 2.7 g/m2, 100.5 ± 15.7 SI, 26.6 ± 7.4 restrained eating DEBQ score and 1523.4 ±1346.8 MET‐min/wk, respectively. Mean ± SE Ca intake was higher among women who supplemented versus those who consumed only dietary Ca (980.11 ± ...

Thirty-eight females (aged 18–24 years) were assigned to 1 of 3 groups: (1) E, (2) ER or (3) active control (AC). The E and ER groups completed 15 weeks of marathon training. The ER group performed additional resistance training and the AC group maintained their usual exercise routine. Primary outcomes were measured pre- and post-training and included anthropometric indices, dual-energy x-ray absorptiometry, plasma CRP, time to complete 1.5 miles (in minutes), and upper and lower body strength tests (i.e., 8 repetition max on bench and leg press (ER group only)). There were no differences in any variable among the groups at baseline. After training, the E group decreased time to complete 1.5 miles (p < 0.05). The AC group decreased percent and absolute body fat while the E group decreased percent body fat, absolute body fat, and android and gynoid body fat (p < 0.05). The ER group significantly improved strength (p < 0.001) and reduced plasma CRP from 2.0 ± 1.1 to 0.8 ± 0.3 mg·L–1 (p = 0.03). No significant associations were observed between CRP and measures of body composition or aerobic capacity. Combined endurance and resistance training may be an effective modality for reducing plasma CRP in young adult females independent of changes in aerobic capacity or body composition.

Outcome measures included: self-reported PA levels calculated in MET-hrs·wk-1 from the International Physical Activity Questionnaire (IPAQ); body mass index (BMI; in kg·m-2); and body composition variables estimated by dual-energy X-ray absorptiometry (DXA). Mean activity levels of the sample were 39.8 ± 23.8 MET-hrs·wk-1. Participants were divided into quartiles of PA levels: ≥0 to <24.0, ≥24.0 to <34.0, ≥34.0 to <51.25, and ≥51.25 MET-hrs ·wk-1 and body composition variables were compared by group. Chi-square analyses revealed a significant difference for gender by PA quartile [χ2 (3, N=290) = 32.42, p < 0.0001], and for gender by race by PA quartile [χ2 (9, N=290) = 37.82, p < 0.0001]. MET-hrs·wk-1 was inversely correlated with %BF (r = -0.40, p < 0.0001) but not BMI (r = 0.05, p = 0.43). When comparing body composition variables across PA quartiles, no significant differences were observed for BMI; however, subjects in the highest quartile of PA had a lower percent body fat (%BF) and fat mass (FM), and a higher lean-tissue mass (LTM) compared to subjects in the other three groups. In this cohort of young adults, participants in the highest activity group had a more fit body composition profile (e.g., lower %BF, lower FM, and higher LTM) which was not reflected in BMI and was independent of gender and race.

METHODS: Fifty eight healthy young adults aged 18-24 yrs (78% female) were assigned to one of three groups: 1) endurance training (E) (n=18), 2) endurance + resistance training (ER) (n=11), or 3) active control (AC) (n=29). The E group completed 15 weeks of endurance training for either a half marathon (n=6) or full marathon (n=12). The ER group performed 15 weeks of periodized resistance training in addition to the half marathon (n=3) or full marathon (n=8) training. The AC group continued the same exercise routine that they had used prior to becoming a study participant. Pre and post measures included: a 1.5 mile run, 8 rep max (8 RMs; ER group only) on the bench and leg presses, height, weight, waist and hip circumference, DXA, and plasma CRP (ELISA). RESULTS: At baseline, no significant differences were observed between groups. In the E group only, estimated VO 2 max significantly increased 12.45% from 38.9 ± 3.8 ml/min/kg to 43.8 ± 7.5 ml/min/kg (mean ± SD) (P < 0.05) and total percent body fat decreased significantly 1.7% from 29.4% ± 8.3 to 27.7 ± 8.8 (mean ± SD) (P < 0.05). In the ER group only, plasma CRP concentrations decreased, but not significantly from 1.59 ± 1.2 mg/L to 0.99 ± 0.5 mg/L (mean ± SD) (P = 0.16). All other measures for the ER group did not change significantly. In addition, while the E and AC groups remained in the average risk category for CRP levels (1-3 mg/L) at the post intervention time point, the ER group entered the low risk category (< 1 mg/L) with an average CRP concentration of 0.99 mg/L. CONCLUSIONS: Combined endurance and resistance training may be an effective modality for reducing plasma CRP in young iv adults. However, improvements in aerobic capacity and total percent body fat do not appear to affect changes in CRP. FUNDING: Louisiana State University

The primary objective of this study was to examine the relationship between children's preferences for fruits and vegetables and their weight status. A total of 341 black children (43% boys; 68% fourth graders) attending low-income, public elementary schools in southeastern Louisiana volunteered to participate. Children were measured for height and weight and completed a survey that sought their preferences for 38 different fruits and vegetables during the fall of 2005. Results indicated that children preferred fruits more than vegetables and that there was a negative association between children's mean fruit and vegetable preference score and their body mass index for age percentile (rϭϪ0.26; Pϭ0.01). Children who reported a very low preference for fruits and vegetables were 5.5 times more likely to be categorized as at risk for overweight or overweight than were those who reported a high preference for fruits and vegetables (odds ratio: 5.5; confidence interval: 1.97 to 15.44; PϽ0.01). It is believed that food preferences are established early in life; therefore, nutritionists and other health care professionals should promote children's acceptance and intake of fruits and vegetables as a measure to reduce the prevalence of overweight among children.
