Descriptive Assessment

The purpose of this study was to provide a descriptive assessment of the nutritional habits of competitive bodybuilders and compare the nutrient intakes of macronutrient-based dieting and strict dieting individuals. Data from 41 subjects (30 males and 11 females) were used in analyses. Participants completed a comprehensive food frequency questionnaire, and diets were analyzed using a computer system. Males consumed an average of 2,577.2 kcal (SD = 955.1), with an average fat intake of 83.6 g (SD = 41.3), an average carbohydrate intake of 323.3 g (SD = 105.2), and an average protein intake of 163.4 g (SD = 70.4). There were no significant differences between male macronutrient-based dieting and strict dieting bodybuilders when mean intakes were compared for all nutrients, including the macronutrients, selected vitamins and minerals, dietary fiber, added sugars, and saturated fat. Females in this study consumed an average of 1,794 kcal (SD = 453.1), with an average fat intake of 58.3 g (SD = 23.1), a mean carbohydrate intake of 217.8 g (SD = 85.9), and an average protein intake of 103.8 g (SD = 35.7). For females, macronutrient-based dieters consumed significantly greater amounts of several nutrients, including protein, vitamin E, vitamin K, and vitamin C. Over half of individuals from all groups consumed less than the recommended amounts of several of the micronutrients. Based on this information, it is recommended that competitive bodybuilders should be advised to take their micronutrition into greater consideration.

Sphingolipid concentrations have been associated with risk of type 2 diabetes and cardiovascular diseases. Because sphingolipids can be synthesized de novo from saturated fatty acids (SFA), dietary fatty acids may affect plasma sphingolipid concentrations. We aimed to evaluate dietary fat and protein intakes in relation to circulating sphingolipid levels. We used cross-sectional data from 2860 ethnic Chinese Singaporeans collected from 2004–2007. Nutrient intakes were estimated on the basis of a validated 159-item food frequency questionnaire. We quantified 79 molecularly distinct sphingolipids in a large-scale lipidomic evaluation from plasma samples. Higher saturated fat intake was associated with higher concentrations of 16:1;O2 sphingolipids including ceramides, monohexosylcermides, dihexosylceramides, sphingomyelins, and sphingosine 1-phosphates. Higher polyunsaturated fat intake was associated with lower plasma long-chain ceramides and long-chain monohexosylcermide concentrations. Protein intake was inversely associated with concentrations of most subclasses of sphingolipids, with the exception of sphingolipids containing a 16:1;O2 sphingoid base. Lower intake of saturated fat and higher intake of polyunsaturated fat and protein may decrease plasma concentrations of several sphingolipid classes. These findings may represent a novel biological mechanism for the impact of nutrient intakes on cardio-metabolic health.

Remaja yang memiliki status gizi kegemukan dan obesitas memiliki resiko lebih tinggi untuk mengalami obesitas di usia dewasa. Asupan karbohidrat sederhana dan lemak jenuh yang tinggi serta aktivitas fisik yang rendah merupakan beberapa faktor yang sering disebut sebagai penyebab terjadinya kegemukan dan obesitas. Penelitian ini menggunakan desain cross sectional dengan tujuan untuk menguji korelasi asupan karbohidrat sederhana, lemak jenuh dan aktivitas fisik dengan status gizi pada remaja yang memiliki status gizi gemuk atau obesitas. Sebanyak 69 orang siswa/i di SMA 3 kota Malang yang berusia 15-17 tahun dan berstatus gizi gemuk atau obesitas menjadi subjek dalam penelitian ini. Asupan karbohidrat sederhana dan lemak jenuh diukur menggunakan form Semi Qualitative Food Frequency (SQ-FFQ) dan Aktivitas fisik melalui wawancara dengan menggunakan form Physical Activity Questionaire for Adolescent (PAQ-A). Uji statistik Gamma and Somers’d dengan SPSS 16 digunakan untuk menguji korelasi antar variabel. Ditemukan bahwa status gizi tidak berhubungan secara bermakna dengan karbohidrat sederhana (p =0,873), asupan lemak jenuh (p=0,343), dan aktivitas fisik (p=0,487). Identifikasi faktor lain pada remaja yang kemungkinan berpengaruh seperti tingkat pengetahuan gizi, durasi waktu tidur, waktu menstruasi pertamakali, tingkat ekonomi keluarga, diperlukan untuk menganalisis faktor resiko yang lebih berhubungan dengan kejadian kegemukan dan obesitas pada remaja.Kata Kunci:  Karbohidrat sederhana, lemak jenuh, aktivitas fisik, obesitasAdolescents with overweight and obesity are at higher risk for obesity in adulthood. Simple carbohydrate intake, high saturated fat intake, and low physical activity are some factors that are often referred to as the cause of overweight and obesity. This study is a cross-sectional research design with the aim to identify the correlation of simple carbohydrate intake, saturated fat and physical activity with nutritional status in overweight and obesity adolescents. Sixty-nine students in SMA 3 Malang city aged 15-17 years were involved in this study. Simple carbohydrate and saturated fat intake were measured using Semi-Qualitative Food Frequency (SQ-FFQ) form and Physical Activity through interview using Physical Activity Questionaire for Adolescent (PAQ-A) form. Gamma and Somers'd statistical test with SPSS 16 were used to test the correlation. Nutritional status did not correlate significantly with simple carbohydrates (p = 0.873), saturated fat intake (p = 0.343), and physical activity (p = 0.487). Identification of other factors in adolescents that may be influential such as the level of nutritional knowledge, sleep duration, first-time menstruation, family economic level, is needed to analyze risk factors more related to overweight and obesity in adolescents.Keywords: Simple carbohydrate, saturated fat, physical activity, obesity

ABSTRACTBackgroundFor low-carbohydrate diets, a public health approach has focused on the replacement of carbohydrates with unsaturated fats. However, little research exists on the impacts of saturated fat intake on the lipid profile in the context of whole-food-based low-carbohydrate weight-loss diets.ObjectivesThe primary aim of this secondary analysis of the DIETFITS weight loss trial was to evaluate the associations between changes in percentage of dietary saturated fatty acid intake (%SFA) and changes in low-density lipoproteins, high-density lipoproteins, and triglyceride concentrations for those following a healthy low-carbohydrate (HLC) diet. The secondary aim was to examine these associations specifically for HLC dieters who had the highest 12-month increases in %SFA.MethodsIn the DIETFITS trial, 609 generally healthy adults, aged 18–50 years, with body mass indices of 28–40 kg/m2 were randomly assigned to a healthy low-fat (HLF) or HLC diet for 12 months. In this analysis, linear regression, both without and with adjustment for potential confounders, was used to measure the association between 12-month change in %SFA and blood lipids in 208 HLC participants with complete diet and blood lipid data.ResultsParticipants consumed an average of 12–18% of calories from SFA. An increase of %SFA, without significant changes in absolute saturated fat intake, over 12 months was associated with a statistically significant decrease in triglycerides in the context of a weight-loss study in which participants simultaneously decreased carbohydrate intake. The association between increase in %SFA and decrease in triglycerides was no longer significant when adjusting for 12-month change in carbohydrate intake, suggesting carbohydrate intake may be a mediator of this relationship.ConclusionsThose on a low-carbohydrate weight-loss diet who increase their percentage intake of dietary saturated fat may improve their overall lipid profile provided they focus on a high-quality diet and lower their intakes of both calories and refined carbohydrates. This trial was registered at clinicaltrials.gov as NCT01826591.

AbstractBackground:The prevalence of chronic diseases is increasing in West Africa, the Caribbean and its migrants to Britain. This trend may be due to the transition in the habitual diet, with increasing (saturated) fat and decreasing fruit and vegetable intakes, both within and between countries.Objective:We have tested this hypothesis by comparing habitual diet in four African-origin populations with a similar genetic background at different stages in this transition.Design:The study populations included subjects from rural Cameroon (n=743), urban Cameroon (n=1042), Jamaica (n=857) and African–Caribbeans in Manchester, UK (n=243), all aged 25–74 years. Habitual diet was assessed by a food-frequency questionnaire, specifically developed for each country separately.Results:Total energy intake was greatest in rural Cameroon and lowest in Manchester for all age/sex groups. A tendency towards the same pattern was seen for carbohydrates, protein and total fat intake. Saturated and polyunsaturated fat intake and alcohol intake were highest in rural Cameroon, and lowest in Jamaica, with the intakes in the UK lower than those in urban Cameroon. The percentage of energy from total fat was higher in rural and urban Cameroon than in Jamaica and the UK for all age/sex groups. The opposite was seen for percentage of energy from carbohydrate intake, the intake being highest in Jamaica and lowest in rural Cameroon. The percentage of energy from protein increased gradually from rural Cameroon to the UK.Conclusions:These results do not support our hypothesis that carbohydrate intake increased, while (saturated) fat intake decreased, from rural Cameroon to the UK.

There is a high prevalence of children with obesity who are participating in sports. Appropriate nutritional considerations are important to optimize health and training adaptations. This review focuses on macronutrient recommendations and their effect on weight management and/or benefits for athletic training for children ages 5 to 18 years. Equal distribution of protein intake throughout the day (~25-30 g/meal) and during postexercise recovery is recommended. Special attention should be given to increasing protein intake during breakfast because it is often the meal with the least protein intake. Both postexercise recommendations for protein (~0.3 g/kg of body weight) and carbohydrate (~1.0-1.2 g/kg/h) were not determined in children with obesity, and require future verification. Individual carbohydrate needs of training to meet fuel costs are recommended, but ~200 to 500 g/day of carbohydrate may be required depending on a child’s level of sport participation and competition. Fat intake should follow general recommendations to meet the accepted macronutrient distribution range in children (25% to 35%) and reduce saturated fat intake. No evidence suggests that additional dietary fat modifications would improve training adaptations in children. Longitudinal studies are required to further our understanding of age and sex effects and confirm the appropriate quantity of macronutrients for active children with obesity.

Determining the ideal ratio of macronutrients for increasing life expectancy remains a high priority in nutrition research. We aim to investigate the association between carbohydrate, fat, and protein intake and all-cause mortality in Koreans. This cohort study investigated 42,192 participants from the Korea National Health and Nutrition Examination Survey (KNHANES) linked with causes of death data (2007–2015). Hazard ratios (HRs) were calculated using the multivariable Cox proportional regression model after adjusting for confounders. We documented 2110 deaths during the follow-up period. Time to exceed 1% of the all-cause mortality rate was longest in participants with 50–60% carbohydrate, 30–40% fat, and 20–30% protein intake. Adjusted hazard ratio (HR) with 95% confidence intervals (CIs) was 1.313 (1.031–1.672, p = 0.0272) for <50% carbohydrate intake, 1.322 (1.116–1.567, p = 0.0013) for ≥60% carbohydrate intake, 1.439 (1.018–2.035, p = 0.0394) for <30% fat intake, and 3.255 (1.767–5.997, p = 0.0002) for ≥40% fat intake. There was no significant association between protein intake proportion and all-cause mortality. We found a U-shaped association between all-cause mortality and carbohydrate intake as well as fat intake, with minimal risk observed at 50–60% carbohydrate and 30–40% fat intake. Our findings suggest current Korean dietary guidelines should be revised to prolong life expectancy.

AbstractObjectives:To assess the reproducibility and validity a 127-item, habitual intake, food-frequency questionnaire (FFQ), developed for low-income and low-literacy Brazilian workers, by comparison with a 24-hour dietary recall (24-HDR).Design:The FFQ and 24-HDR were interviewer-administered at the local workplace to each subject twice, with a period of 6 months between estimates; and four 24-HDRs were conducted during the 4-month period between the two FFQs (FFQ1 and FFQ2). Reproducibility was tested by comparing mean nutrient intakes from the two FFQs. Validity was determined by comparing the mean nutrient intakes from the FFQs with the corresponding averages of the six 24-HDRs (reference method).Setting:Goiânia City, in Central West Brazil.Subjects:The study was based on 104 (62 women and 42 men) subjects, aged 18 to 60 years, who were randomly selected.Results:Dietary intake from the FFQ was higher than from the 24-HDR. Reproducibility was assessed by Pearson correlation coefficients for nutrients from FFQ1 and FFQ2, and ranged from 0.23 for retinol to 0.69 for total energy (mean 0.52). Intra-class coefficients for nutrients averaged by the 24-HDRs ranged from 0.29 for vitamin C to 0.76 for total energy; retinol was not significant. In the validation study, correlation between the FFQ and the 24-HDR ranged between 0.21 for vitamin C and 0.70 for total energy (mean 0.50). Adjusting for total energy lowered the coefficients, except for calcium, retinol and vitamin C. Coefficients increased with attenuation, ranging from 0.35 for carbohydrate to 0.65 for calcium.Conclusions:Results indicate that this questionnaire had satisfactory reproducibility and reasonable validity.

In order to better understand the factors that may influence and regulate the intake of the macronutrients carbohydrate, fat and protein a 7 d diet diary technique was employed to study eating behaviour in the natural environment of free-living human subjects. In general, factors that promote energy intake tend to promote fat and protein intake to a greater extent than carbohydrate intake. This increased intake occurs as the result of: environmental factors such as social facilitation and the time of day, week or lunar phase; subjective factors such as hunger and elation; individual difference factors such as obesity, restraint and ageing. There are indications that the intake of macronutrients is regulated by negative feedback systems. In the short term, the amount of protein remaining in the stomach at the onset of a meal appears to have a restraining effect on intake, especially protein intake. Over several days, macronutrient intake appears to be affected by a nutrient-specific delayed negative feedback. Protein intake during 1 d is negatively associated with protein intake 2 and 3 d later, while carbohydrate intake is negatively related to later carbohydrate intake, and fat intake to later fat intake; both peaking after a 2 d delay. Studies of the intakes of twins suggested that many aspects of the control of macronutrient intake are influenced by inheritance; these factors include the overall amounts ingested, the before-meal stomach contents and the responsiveness of the subject to the negative impact of the stomach contents. The results indicate that macronutrient intakes are regulated by multiple persistent processes that are to a large extent inherited.

Because sphingolipids can be synthesized de novo from saturated fatty acids (SFA), dietary fatty acids may affect plasma sphingolipid concentrations. We aimed to evaluate dietary fat and protein intakes in relation to circulating sphingolipid levels.

We quantified 79 molecularly distinct sphingolipids in a large-scale lipidomic evaluation from plasma samples. Results Higher saturated fat intake was associated with higher concentrations of 16:1; O2 sphingolipids including ceramides, monohexosylcermides, dihexosylceramides, sphingomyelins, and sphingosine 1-phosphates. Higher polyunsaturated fat intake was associated with lower plasma long-chain ceramides and long-chain monohexosylcermide concentrations. Protein intake was inversely associated with concentrations of most subclasses of sphingolipids, with the exception of sphingolipids containing a 16:1; O2 sphingoid base. Lower intake of saturated fat and higher intake of polyunsaturated fat and protein may decrease plasma concentrations of several sphingolipid classes. Conclusions These findings may represent a novel biological mechanism for the impact of nutrient intakes on cardio-metabolic health.
