Abstract Objective: Investigate protein intake patterns over the day and their association with total protein intake in older adults. Design: Cross-sectional study utilising the dietary data collected through two non-consecutive, dietary record-assisted 24-h recalls. Days with low protein intake (n 290) were defined using the RDA (<0·8 g protein/kg adjusted BW/d). For each day, the amount and proportion of protein ingested at every hour of the day and during morning, mid-day and evening hours was calculated. Amounts and proportions were compared between low and high protein intake days and related to total protein intake and risk of low protein intake. Setting: Community. Participants: 739 Dutch community-dwelling adults ≥70 years. Results: The mean protein intake was 76·3 (sd 0·7) g/d. At each hour of the day, the amount of protein ingested was higher on days with a high protein intake than on days with a low protein intake and associated with a higher total protein intake. The proportion of protein ingested during morning hours was higher (22 v. 17 %, P < 0·0001) on days with a low protein intake, and a higher proportion of protein ingested during morning hours was associated with a lower total protein intake (P < 0·0001) and a higher odds of low protein intake (OR 1·04, 95 % CI 1·03, 1·06). For the proportion of protein intake during mid-day or evening hours, opposite but weaker associations were found. Conclusions: In this sample, timing of protein intake was associated with total protein intake. Additional studies need to clarify the importance of these findings to optimise protein intake.

The Relationship

In older adults, the relationship between healthy eating motivation (HEM) and protein intake as key component of a healthy diet is poorly understood. Therefore, we investigate the association of HEM with (1) total protein intake and (2) intake of different protein sources in older adults with varying functional status. In this cross-sectional study including 250 adults (≥70 years), we assessed HEM with “The Eating Motivation Survey” and protein intake by 7-day food records. In addition, gender, age, Body Mass Index (BMI), energy intake and functional status were considered. Regression analyses revealed that HEM was neither related to total (β = −0.02; p = 0.723) nor to relative protein intake (β = 0.04; p = 0.370). Notwithstanding this, participants with stronger HEM showed lower intake of protein from meat and meat products (β = −0.14; p = 0.018), higher intake of overall plant-based protein (β = 0.11; p = 0.032), protein from fruit and vegetables (β = 0.20; p = 0.002) and from pulses, nuts an seeds (β = 0.16; p = 0.016). Our findings suggest HEM as a valuable indicator for intake of distinct protein sources. However, since HEM is not related to total protein intake, the importance of sufficient protein consumption should be emphasized by promoting healthy eating, regardless of self-perceived HEM.

(1) Background: The present work aims to conduct a systematic review and meta-analysis of observational studies, in order to investigate the association of relative protein intake and physical function in older adults; (2) Methods: Observational studies, that investigated the association between protein intake and physical function in older adults, were retrieved from MEDLINE, SCOPUS, CINAHL, AgeLine, EMBASE, and Cochrane-CENTRAL. Two independent researchers conducted study selection and data extraction; (3) Results: Very high protein intake (≥1.2 g/kg/day) and high protein intake (≥1.0 g/kg/day) groups showed better lower limb physical functioning and walking speed (WS) performance, respectively, in comparison to individuals who present relative low protein (<0.80 g/kg/day) intake. On the other hand, relative high protein intake does not seem to propitiate a better performance on isometric handgrip (IHG) and chair rise in comparison to relative low protein intake. In addition, there were no significant differences in the physical functioning of high and middle protein intake groups; (4) Conclusions: In conclusion, findings of the present study indicate that a very high (≥1.2 g/kg/day) and high protein intake (≥1.0 g/kg/day) are associated with better lower-limb physical performance, when compared to low protein (<0.80 g/kg/day) intake, in community-dwelling older adults. These findings act as additional evidence regarding the potential need to increase protein guidelines to above the current recommendations. However, large randomized clinical trials are needed to confirm the addictive effects of high-protein diets (≥1.0 g/kg/day) in comparison to the current recommendations on physical functioning.

Eating Occasions

Physical activity and protein intake are associated with ageing-related outcomes, including loss of muscle strength and functional decline, so may contribute to strategies to improve healthy ageing. We investigated the cross-sectional associations between physical activity or sedentary behaviour and protein intake patterns in community-dwelling older adults across five countries. Self-reported physical activity and dietary intake data were obtained from two cohort studies (Newcastle 85+ Study, UK; LiLACS, New Zealand Māori and Non-Māori) and three national food consumption surveys (DNFCS, The Netherlands; FINDIET, Finland; INRAN-SCAI, Italy). Associations between physical activity and total protein intake, number of eating occasions providing protein, number of meals with specified protein thresholds, and protein intake distribution over the day (calculated as a coefficient of variance) were assessed by regression and repeated measures ANOVA models adjusting for covariates. Greater physical activity was associated with higher total protein intake and more eating occasions containing protein, although associations were mostly explained by higher energy intake. Comparable associations were observed for sedentary behaviour in older adults in Italy. Evidence for older people with higher physical activity or less sedentary behaviour achieving more meals with specified protein levels was mixed across the five countries. A skewed protein distribution was observed, with most protein consumed at midday and evening meals without significant differences between physical activity or sedentary behaviour levels. Findings from this multi-study analysis indicate there is little evidence that total protein and protein intake patterns, irrespective of energy intake, differ by physical activity or sedentary behaviour levels in older adults.

Abstract Background Proteins are an essential part of medical nutrition therapy in critically ill patients. Guidelines almost universally recommend a high protein intake without robust evidence supporting its use. Methods Using a large international database, we modelled associations between the hazard rate of in-hospital death and live hospital discharge (competing risks) and three categories of protein intake (low: < 0.8 g/kg per day, standard: 0.8–1.2 g/kg per day, high: > 1.2 g/kg per day) during the first 11 days after ICU admission (acute phase). Time-varying cause-specific hazard ratios (HR) were calculated from piece-wise exponential additive mixed models. We used the estimated model to compare five different hypothetical protein diets (an exclusively low protein diet, a standard protein diet administered early (day 1 to 4) or late (day 5 to 11) after ICU admission, and an early or late high protein diet). Results Of 21,100 critically ill patients in the database, 16,489 fulfilled inclusion criteria for the analysis. By day 60, 11,360 (68.9%) patients had been discharged from hospital, 4,192 patients (25.4%) had died in hospital, and 937 patients (5.7%) were still hospitalized. Median daily low protein intake was 0.49 g/kg [IQR 0.27–0.66], standard intake 0.99 g/kg [IQR 0.89– 1.09], and high intake 1.41 g/kg [IQR 1.29–1.60]. In comparison with an exclusively low protein diet, a late standard protein diet was associated with a lower hazard of in-hospital death: minimum 0.75 (95% CI 0.64, 0.87), and a higher hazard of live hospital discharge: maximum HR 1.98 (95% CI 1.72, 2.28). Results on hospital discharge, however, were qualitatively changed by a sensitivity analysis. There was no evidence that an early standard or a high protein intake during the acute phase was associated with a further improvement of outcome. Conclusions Provision of a standard protein intake during the late acute phase may improve outcome compared to an exclusively low protein diet. In unselected critically ill patients, clinical outcome may not be improved by a high protein intake during the acute phase. Study registration ID number ISRCTN17829198

AbstractIntroductionHome-delivered hot meals and dairy could possibly prevent community-dwelling (CD) older adults from becoming malnourished when they are no longer able to cook themselves. Ideally, these products contribute to an intake of 1.2 grams of protein per kg bodyweight per day (g/kg BW/d) and ≥ 25 grams of protein per main meal. This study evaluated the effectiveness of these products on protein intake and explored the acceptance of these products.MethodsThe study was a single-blind RCT with CD older adults switching from self-prepared to commercially-available home-delivered hot meals and dairy products during 28 days. The intervention group (I) received meals and dairy products high in (≥ 20EN%) protein; the control group (C) received standard meals and dairy products low(er) in protein. Dietary intake was measured at baseline, two weeks (T1) and four weeks (T2) by a three-day food diary. After study completion, 25 participants (aged > 80y, 16 female/9 male) participated in focus groups discussing information on healthy eating, attitude towards high protein products, product acceptance.ResultsNinety-eight CD older adults (mean age: 80.4 years ± 6.8). Baseline protein intake was 1.09 (SE 0.05) (I) and 0.99 (SE 0.05) (C) g/kg BW/d. During the trial, protein intake of I remained stable at 1.12 g/kg BW/d (SE 0.05) while intake decreased in C to 0.87 (SE 0.03). More I participants reached the threshold of ≥ 25 grams protein at dinner compared to C but not at breakfast and lunch. In the focus groups, participants indicated to be aware of the importance of healthy eating (less salt and less fat). However, knowledge on high-protein products was low and participants did not know why intake of protein should be increased. Less social interaction was indicated as one of the main causes of deterioration of eating behaviour. Further, participants indicated that they primarily would like to enjoy eating instead of focusing on functionality. The ready-made meals were generally considered to be too large and low in vegetables.ConclusionsSwitching from self-prepared meals to ready-made meals carries the risk of a decreasing protein intake in CD older adults. To stimulate a healthy dietary pattern, focus should be on behavioural change and knowledge improvement. Besides awareness for healthy eating, food enjoyment is essential. Finally, meal composition could be improved to enhance acceptance.

Reduction of renal mass in the rat results in an increased glomerular prostaglandin (PG) and thromboxane (TX) formation that modulates renal hemodynamics. To evaluate whether dietary protein intake could exert effects on renal PG and TX formation after reduction of approximately 70% of renal mass, rats with remnant kidneys were placed on either a high-protein (HP) or a low-protein (LP) diet. After 2 wk on the diet, proteinuria, glomerular filtration rate (GFR), urinary PGE2 excretion, and glomerular PGE2, 6-keto PGF1 alpha, and TxB2 biosynthesis were significantly greater in the rats on HP diets. Two-wk administration of the thromboxane synthesis inhibitor UK 38485 reduced renal TxB2 formation by approximately 70%. In addition, chronic UK 38485 treatment significantly inhibited papillary PGE2 production. Neither chronic nor bolus administration of UK 38485 had an effect on proteinuria or GFR in rats on HP diets. Chronic UK 38485 treatment, however, reduced GFR and proteinuria in rats on LP diets. The bolus administration of UK 38485 did not alter GFR in animals receiving a LP diet. The cyclooxygenase inhibitor indomethacin reduced GFR only in rats on HP diets. The data demonstrate that HP intake stimulates renal prostanoid formation. The increased prostaglandin formation on HP intake modulates GFR in these rats.
