[Ab] Resumo:Background: In case of shortage of breast milk despite proper lactation care or the poor state of the mother's health, breast milk from human milk bank is recommended for feeding preterm infants Objective: This study retrospectively evaluated the first year of the operation of the Regional Human Milk Bank Material and methods: Data concerning donors was collected in the human milk bank during the cooperation. The clinical characteristics of the recipients was made on the basis of medical documentation from the Holy Family Hospital in Warsaw, Poland. Analysis of nutritional value was performed with the human milk analyzer (MIRIS AB) Results: In the first year of activity, 45 voluntary donors established cooperation, donating from 650 to 32030 ml of human milk. The content of nutrients in milk provided by donors was variable - protein 0.4-1.5 g / 100 ml, fat 1.1-7.4 g / 100 ml, carbohydrates 6.3-7.9 g / 100 ml. The average length of using donated human milk was 4 days and the average volume of milk for one infant was 282 ml Conclusions: The donor profiles have a significant impact on the milk composition form HMB. The nutritional value can be improved by recruitment donors from mothers that gave birth prematurely and by beginning donation at earlier stages of lactation as soon as lactation is stabilized. In case of shortage of mothers own milk the immediate implementation of donors milk as a short-term support can significantly reduce the food intolerance incidence in the group of prematurely born infants

[Ti] Título:The short-term effect of high versus moderate protein intake on recovery after strength training in resistance-trained individuals.

[Ab] Resumo:Background: Dietary protein intakes up to 2.9 g.kg .d and protein consumption before and after resistance training may enhance recovery, resulting in hypertrophy and strength gains. However, it remains unclear whether protein quantity or nutrient timing is central to positive adaptations. This study investigated the effect of total dietary protein content, whilst controlling for protein timing, on recovery in resistance trainees. Methods: Fourteen resistance-trained individuals underwent two 10-day isocaloric dietary regimes with a protein content of 1.8 g.kg .d (PRO ) or 2.9 g.kg .d (PRO ) in a randomised, counterbalanced, crossover design. On days 8-10 (T1-T3), participants undertook resistance exercise under controlled conditions, performing 3 sets of squat, bench press and bent-over rows at 80% 1 repetition maximum until volitional exhaustion. Additionally, participants consumed a 0.4 g.kg whey protein concentrate/isolate mix 30 min before and after exercise sessions to standardise protein timing specific to training. Recovery was assessed via daily repetition performance, muscle soreness, bioelectrical impedance phase angle, plasma creatine kinase (CK) and tumor necrosis factor-α (TNF-α). Results: No significant differences were reported between conditions for any of the performance repetition count variables ( > 0.05). However, within PRO only, squat performance total repetition count was significantly lower at T3 (19.7 ± 6.8) compared to T1 (23.0 ± 7.5; = 0.006). Pre and post-exercise CK concentrations significantly increased across test days ( ≤ 0.003), although no differences were reported between conditions. No differences for TNF-α or muscle soreness were reported between dietary conditions. Phase angle was significantly greater at T3 for PRO (8.26 ± 0.82°) compared with PRO (8.08 ± 0.80°; = 0.012). Conclusions: When energy intake and peri-exercise protein intake was controlled for, a short term PRO diet did not improve markers of muscle damage or soreness in comparison to a PRO approach following repeated days of intensive training. Whilst it is therefore likely that moderate protein intakes (1.8 g.kg .d ) may be sufficient for resistance-trained individuals, it is noteworthy that both lower body exercise performance and bioelectrical phase angle were maintained with PRO . Longer term interventions are warranted to determine whether PRO intakes are sufficient during prolonged training periods or when extensive exercise (e.g. training twice daily) is undertaken.

[Ab] Resumo:It is known that the macronutrient content of a meal has different impacts on the postprandial satiety and appetite hormonal responses. Whether obesity interacts with such nutrient-dependent responses is not well characterized. We examined the postprandial appetite and satiety hormonal responses after a high-protein (HP), high-carbohydrate (HC), or high-fat (HF) mixed meal. This was a randomized cross-over study of 9 lean insulin-sensitive (mean±SEM HOMA-IR 0.83±0.10) and 9 obese insulin-resistant (HOMA-IR 4.34±0.41) young (age 21-40 years), normoglycaemic Chinese men. We measured fasting and postprandial plasma concentration of glucose, insulin, active glucagon-like peptide-1 (GLP-1), total peptide-YY (PYY), and acyl-ghrelin in response to HP, HF, or HC meals. Overall postprandial plasma insulin response was more robust in the lean compared to obese subjects. The postprandial GLP-1 response after HF or HP meal was higher than HC meal in both lean and obese subjects. In obese subjects, HF meal induced higher response in postprandial PYY compared to HC meal. HP and HF meals also suppressed ghrelin greater compared to HC meal in the obese than lean subjects. In conclusion, a high-protein or high-fat meal induces a more favorable postprandial satiety and appetite hormonal response than a high-carbohydrate meal in obese insulin-resistant subjects.

[Ab] Resumo:INTRODUCTION: Distributing daily protein intake evenly across meals (∼25-30g/meal) has been suggested to improve muscle mass. The aim of this research is to examine the association between grip strength, total protein intake and its distribution across day's meals in older adults. METHODS: Nationally representative dietary intake data of adults aged 51 years and older (n = 4,123) who participated in What We Eat in America, NHANES 2011-2014 were analyzed. Protein intake per day and per eating occasion (breakfast, lunch, dinner, and snack) were determined. Combined grip strength was calculated and expressed in kilograms. Grip strength of individuals consuming ≥25g protein at 1 eating occasion was compared with those consuming same level of protein at 2 and 3 or more eating occasions. Grip strength of individuals in quartile 1 of daily protein intake was compared to those in the other quartiles. All associations were examined without and with adjustment for age, race/ethnicity, physical activity, health status, and smoking status. The comparison involving eating occasions and protein intake quartiles were further adjusted for daily protein intake and energy intake, respectively. RESULTS: Only 33% of men and 19% of women had protein intake of ≥25g at 2 or more eating occasions. These individuals also had higher grip strength and daily protein intake. Grip strength was positively associated with consumption of ≥25g protein at 2 eating occasions as compared to consumption of same level of protein at 1 eating occasion (p<0.05) in unadjusted model, but not when adjusted. Grip strength was positively associated with daily protein intake among women in quartiles 3 and 4 (p<0.05) of protein intake in both unadjusted and adjusted models compared to lowest protein intake. Among men, grip strength was associated with daily protein intake in quartiles 3 and 4 (p<0.05) in the unadjusted model, but not when adjusted. CONCLUSION: In a nationally representative sample of older adults, consuming ≥25g protein at 2 or more eating occasions was not associated with grip strength. However, higher daily protein intake was positively associated with grip strength in women.

[Ab] Resumo:The aim of the work is comparative assessment of efficiency of a hypocaloric diet with inclusion of proteinaceous and vitamin cocktails at obesity. 90 patients with obesity of the II­III degree at the age of 18­65 years by the principle of casual selection were divided into three groups. Control group (30 patients) received a standard low-calorie diet with an energy value of 1600 kcal/day. The diet of the 1st group (30 patients) was modified by the inclusion of protein-vitamin-mineral cocktail (16 g of dry mixture with the addition of 250 ml of yogurt 1.0% fat) twice a day, diet of the 2nd group (30 patients) ­ the inclusion of a protein cocktail (16 g of dry mixture with the addition of 250 ml of yogurt 1.0% fat), while excluding from the diet equivalent caloric meals. The 1st group of patients had a decrease in fat mass by 4.2±0.7 kg (p<0.02), in active lean mass by 1.1±0.1 kg, in total fluid volume by 2.2±0.3 kg (p<0.02). The 2nd group of patients had a decrease in fat mass by 3.8±0.9 kg (p<0.01), in lean mass by 1.4±0.3 kg and in the total fluid volume by 3.1±0.9 l (p<0.02). In the control group attention should be paid to a decrease in lean mass by 1.9±0.6 kg, while fat mass decreased by 3.0±0.4 kg (p<0.02) and the total fluid volume by 3.1±0.9 l (p<0.02). Evaluation of the changes of serum biochemical parameters after treatment demonstrated that the 1st group of patients had significant favorable dynamics of reduction of serum level of total cholesterol, uric acid and glucose (17.7, 28.2 and 18.3%, respectively), which was more pronounced compared with the dynamics in the control group (the decrease by 15, 19.2 and 8.2%, respectively). In the 2nd group of patients the decrease rate of the observed parameters was less pronounced (15, 19.2 and 8.2%, respectively). More appreciable favorable dynamics of biochemical parameters and reduction in body weight in the 1st and 2nd groups in relation to the control group allow to reasonably apply the protein-vitamin cocktails in a diet therapy at obesity.

[Ab] Resumo:A multicenter cross-sectional study with the participation of 356 healthy children aged 1 to 3 years from the cities of the Central Federal District: Moscow (n=106), Ivanovo (n=126), Yaroslavl (n=124) has been carried out. Questionnaire method, the method of 24-hour diet recall for 3 days (2 weekdays and 1 weekend) and the method of diary recording of food intake were used. The average daily volumes of food were consistent with the recommended age norms only in 31.2% of the surveyed children; after 1 year of life children actively started to transfer to nutrition from the family table and only 51.7% of children continued to receive individually prepared for baby food. The recommended dietary allowances were inadequate in macro- and micronutrients: 48.6% of all children received excessive amounts of protein and fat, and 74.1% were less in carbohydrates. The consumption of vitamins D and A and minerals (calcium, iron and zinc) did not correspond to existing recommendations in the majority of cases: only 10-30% of the examined children received physiological norms of vitamins from food and 13-34% - some minerals and trace elements. These results indicate that the nutrition of young children living in the Central Federal District is imbalanced on daily caloric, macro- and micronutrient composition, does not fully meet the requirements of the balanced diet and needs serious optimization.

[Ti] Título:Effects of dietary level of tannic acid and protein on internal organ weights and biochemical blood parameters of rats.

[Ab] Resumo:Tannic acid (TA) is a polyphenolic compound with a health-promoting potential for humans. It is hypothesised that TA effects on the relative weight of internal organs and biochemical blood indices are modified by dietary protein level in rats. The study involved 72 rats divided into 12 groups fed diets with 10 or 18% of crude protein (CP) and supplemented with 0, 0.25, 0.5, 1, 1.5 or 2% of TA. After 3 weeks of feeding, the relative weight of the caecum was greater in rats fed TA diets, while feeding diets with 10% of CP increased the relative weight of the stomach, small intestine and caecum, but decreased that of kidneys and spleen. Albumin concentration was higher in rats fed 0.25% and 0.5% TA diets than in rats given the 2% TA diets. The 2% TA diets reduced creatine kinase (CK) activity compared to non-supplemented diets and those with 0.5, 1 and 1.5% of TA. Rats fed the 10% CP diets had a higher activity of alkaline phosphatase, amylase, and γ-glutamyltransferase as well as the concentration of iron and cholesterol, but lower that of urea and uric acid. The interaction affected only cholinesterase activity. In conclusion, TA induced caecal hypertrophy and could act as a cardioprotective agent, as demonstrated by reduced CK activity, but these effects were not modified by dietary protein level.

[Ab] Resumo:Athletes as well as elderly or hospitalized patients use dietary protein supplementation to maintain or grow skeletal muscle. It is recognized that high quality protein is needed for muscle accretion, and can be obtained from both animal and plant-based sources. There is interest to understand whether these sources differ in their ability to maintain or stimulate muscle growth and function. In this study, baseline muscle performance was assessed in 50 adult Sprague-Dawley rats after which they were assigned to one of five semi-purified "Western" diets (n = 10/group) differing only in protein source, namely 19 kcal% protein from either milk protein isolate (MPI), whey protein isolate (WPI), soy protein isolate (SPI), soy protein concentrate (SPC) or enzyme-treated soy protein (SPE). The diets were fed for 8 weeks at which point muscle performance testing was repeated and tissues were collected for analysis. There was no significant difference in food consumption or body weights over time between the diet groups nor were there differences in terminal organ and muscle weights or in serum lipids, creatinine or myostatin. Compared with MPI-fed rats, rats fed WPI and SPC displayed a greater maximum rate of contraction using the in vivo measure of muscle performance (p<0.05) with increases ranging from 13.3-27.5% and 22.8-29.5%, respectively at 60, 80, 100 and 150 Hz. When the maximum force was normalized to body weight, SPC-fed rats displayed increased force compared to MPI (p<0.05), whereas when normalized to gastrocnemius weight, WPI-fed rats displayed increased force compared to MPI (p<0.05). There was no difference between groups using in situ muscle performance. In conclusion, soy protein consumption, in high-fat diet, resulted in muscle function comparable to whey protein and improved compared to milk protein. The benefits seen with soy or whey protein were independent of changes in muscle mass or fiber cross-sectional area.

[Ab] Resumo:Protein can modulate the surgical stress response and postoperative catabolism. Enhanced Recovery After Surgery (ERAS) protocols are evidence-based care bundles that reduce morbidity. In this study, we compared protein adequacy as well as energy intakes, gut function, clinical outcomes, and how well nutritional variables predict length of hospital stay (LOS) in patients receiving ERAS protocols and conventional care. We conducted a prospective cohort study in adult elective colorectal resection patients after conventional ( = 46) and ERAS ( = 69) care. Data collected included preoperative Malnutrition Screening Tool (MST) score, 3-d food records, postoperative nausea, LOS, and complications. Multivariable regression analysis assessed whether low protein intakes and the MST score were predictive of LOS. Total protein intakes were significantly higher in the ERAS group due to the inclusion of oral nutrition supplements (conventional group: 0.33 g · kg · d ; ERAS group: 0.54 g · kg · d ; < 0.02). This group difference in protein intake was maintained in a multivariable model that controlled for differences between baseline and surgical variables ( = 0.001). Oral food intake did not differ between the 2 groups. The ERAS group had shorter LOS ( = 0.049) and fewer total infectious complications ( = 0.01). Nausea was a predictor of protein intake. Nutrition variables were independent predictors of earlier discharge after potential confounders were controlled for. Each unit increase in preoperative MST score predicted longer LOSs of 2.5 d (95% CI: 1.5, 3.5 d; < 0.001), and the consumption of ≥60% of protein requirements during the first 3 d of hospitalization was associated with a shorter LOS of 4.4 d (95% CI: -6.8, -2.0 d; < 0.001). ERAS patients consumed more protein due to the inclusion of oral nutrition supplements. However, total protein intake remained inadequate to meet recommendations. Consumption of ≥60% protein needs after surgery and MST scores were independent predictors of LOS. This trial was registered at clinicaltrials.gov as NCT02940665.

[Ab] Resumo:INTRODUCTION: Wildlife is an important source of protein for many people in developing countries. Yet wildlife depletion due to overexploitation is common throughout the humid tropics and its effect on protein security, especially for vulnerable households, is poorly understood. This is problematic for both sustainable rural development and conservation management. METHODS: This study investigates a key dimension of protein security in a cash-crop farming community living in a wildlife-depleted farm-forest landscape in SW Ghana, a region where protein-energy malnutrition persists. Specifically, we monitored protein sufficiency, defined as whether consumption met daily requirements, as benchmarked by recommended daily allowance (RDA). We focus on whether more vulnerable households were less likely to be able to meet their protein needs, where vulnerability was defined by wealth, agricultural season and gender of the household head. Our central hypothesis was: (a) vulnerable households are less likely to consume sufficient protein. In the context that most plant proteins were home-produced, so likely relatively accessible to all households, while most animal proteins were purchased, so likely less accessible to vulnerable households, we tested two further hypotheses: (b) vulnerable households depend more on plant protein to cover their protein needs; and (c) vulnerable households are less likely to earn sufficient cash income to meet their protein needs through purchased animal sources. RESULTS: Between 14% and 60% of households (depending on plant protein content assumptions) consumed less than the RDA for protein, but neither protein consumption nor protein sufficiency co-varied with household vulnerability. Fish, livestock and food crops comprised 85% of total protein intake and strongly affected protein sufficiency. However, bushmeat remained an important protein source (15% of total consumption), especially during the post-harvest season when it averaged 26% of total protein consumption. Across the year, 89% of households experienced at least one occasion when they had insufficient income to cover their protein needs through animal protein purchases. The extent of this income shortage was highest during the lean season and among poorer households. CONCLUSIONS: These findings indicate that despite wildlife depletion, bushmeat continues to make a substantial contribution to protein consumption, especially during the agricultural lean season. Income shortages among farmers limit their ability to purchase bushmeat or its substitutes, suggesting that wildlife depletion may cause malnutrition.
