Background: Dietary protein may beneficially influence blood pressure (BP), but evidence is not conclusive. Objective: To quantify the association of total protein, plant protein, and animal protein intake with BP and incident hypertension by means of meta-analysis. Methods: A systematic literature search for eligible studies was conducted until January 2012, using MEDLINE and manual search. Of >3,000 titles evaluated, 29 met the inclusion criteria. Dose-response meta-analyses were performed using STATA 11.0. We included 8 cross-sectional studies (total of 48,985 participants), 4 prospective studies (11,761 participants), and 17 randomized controlled trials (1,449 subjects). Results: Total protein intake was significantly inversely associated with systolic BP ([[Unable to Display Character: &#8209;]]0.20 mmHg per SD, 95%-CI: [[Unable to Display Character: &#8209;]]0.39 to [[Unable to Display Character: &#8209;]]0.01) in cross-sectional studies, but no relation was found with incident hypertension in prospective studies (HR of 0.99 per SD, 95%-CI: 0.96 to 1.02). Trials showed an overall reduction of [[Unable to Display Character: &#8209;]]2.1 mmHg in systolic BP (95%-CI:[[Unable to Display Character: &#8209;]]2.9 to [[Unable to Display Character: &#8209;]]1.4) for a weighed difference in protein intake of 41 g/d, compared to carbohydrates. Plant protein, but not animal protein, was weakly inversely associated with BP in cross-sectional studies. Plant protein and animal protein showed similar associations in prospective studies (non-significant HR of 0.96 and 0.98 per SD, respectively) and randomized trials (-2.0 vs -2.2 mmHg, P<0.05, respectively). Conclusion: Dietary protein may have a beneficial effect on BP if consumed instead of carbohydrates. No clear difference was observed between plant and animal protein, but data on protein from different sources and BP is scarce and more research is needed to draw conclusions.

AbstractObjectiveTo validate a 53-item quantitative FFQ (QFFQ) for the assessment of dietary protein intake in type 2 diabetic outpatients in Bamako, Mali.DesignConsumption of protein-containing foods over the week preceding the interview was measured with a 7d QFFQ and compared with intakes measured with 48-h recalls.SettingCentre National de Lutte contre le Diabète.SubjectsSeventeen male and forty female adults with type 2 diabetes.ResultsCorrelation between protein intakes estimated using the QFFQ and 48h recalls was 0·63 (P< 0·0001). There was no significant difference between the two methods concerning the total protein daily intakes and intakes per kilogram of body weight. The QFFQ indicated that foods of animal origin were a lesser source of protein. Animal protein intake did not differ between men and women but sources did. In men, the main sources were beef (54 % of total animal protein), fish (15 %) and milk powder (8 %). In women, the principal sources were fish (28 %), beef (20 %) and birds (13 %). In contrast, plant protein intake was significantly higher in men than in women (P= 0·01), but the same plant foods contributed in similar proportions for both genders, rice being by far the greatest source (47 % of plant protein in men, 53 % in women).ConclusionThe QFFQ developed in this study is a valid tool to evaluate dietary protein intakes in Malian diabetic subjects. While the total protein intakes were low in both men and women, differences in choices and amounts of protein food sources were shown.

Protein Consumption

The relationship between dietary protein consumption and the risk of type 2 diabetes (T2D) has been inconsistent. The aim of this meta-analysis was to explore the relations between dietary protein consumption and the risk of T2D. We conducted systematic retrieval of prospective studies in PubMed, Embase, and Web of Science. Summary relative risks were compiled with a fixed effects model or a random effects model, and a restricted cubic spline regression model and generalized least squares analysis were used to evaluate the diet–T2D incidence relationship. T2D risk increased with increasing consumption of total protein and animal protein, red meat, processed meat, milk, and eggs, respectively, while plant protein and yogurt had an inverse relationship. A non-linear association with the risk for T2D was found for the consumption of plant protein, processed meat, milk, yogurt, and soy. This meta-analysis suggests that substitution of plant protein and yogurt for animal protein, especially red meat and processed meat, can reduce the risk for T2D.

Beneficial Effects

High protein intake in early childhood is associated with obesity, suggesting possible adverse effects on other cardiometabolic outcomes. However, studies in adults have suggested beneficial effects of protein intake on blood pressure (BP) and lipid profile. Whether dietary protein intake is associated with cardiovascular and metabolic health in children is unclear. Therefore, we aimed to systematically review the evidence on the associations of protein intake with BP, insulin sensitivity and blood lipids in children. We searched the databases Medline, Embase, Cochrane Central and PubMed for interventional and observational studies in healthy children up to the age of 18 years, in which associations of total, animal and/or vegetable protein intake with one or more of the following outcomes were reported: BP; measures of insulin sensitivity; cholesterol levels; or TAG levels. In the search, we identified 6636 abstracts, of which fifty-six studies met all selection criteria. In general, the quality of the included studies was low. Most studies were cross-sectional, and many did not control for potential confounders. No overall associations were observed between protein intake and insulin sensitivity or blood lipids. A few studies suggested an inverse association between dietary protein intake and BP, but evidence was inconclusive. Only four studies examined the effects of vegetable or animal protein intake, but with inconsistent results. In conclusion, the literature, to date provides insufficient evidence for effects of protein intake on BP, insulin sensitivity or blood lipids in children. Future studies could be improved by adequately adjusting for key confounders such as energy intake and obesity.

Background: Adolescent girls in Afghanistan have high levels of food insecurity, yet little is known about their dietary intakes. Therefore, we aimed to study the association between dietary protein intake and anthropometric indices among adolescent girls in Kabul, Afghanistan. Methods: We conducted a cross-sectional study of 380 adolescent girls at 16 government schools from eight randomly sampled zones in Kabul. In July 2019, we assessed dietary intake, body mass index (BMI), physical activity and socio-demographic variables. Binary logistic regression models were used to estimate the associations between different protein sources (plant protein, animal protein and total protein) and stunting, wasting, overweight and obesity. Results: Participant mean age was 14.8±2 years and mean BMI was 19.8±3.6kg/m2. The mean intakes of carbohydrates from plant proteins, animal proteins and total proteins were approximately 59.4±19.6gr/day, 22.3±7.3gr/day and 81.8±27.1gr/day, respectively. Students with more highly educated fathers consumed more plant proteins (P<0.05). Participants had overall high dietary plant protein intake (mean 34.8±22.0g/day), with 66% from grains, cereals and flour. We did not find an association between dietary protein intake and stunting (OR=0.92; CI: 0.55-1.54), wasting (OR= 0.98; CI: 0.55-1.78), overweight (OR=1.18; CI: 0.62-2.25) or obesity (OR=0.84; CI: 0.19-3.58). Conclusion: While prior research suggests that dietary protein intake is associated with improved nutritional and anthropometric indices, dietary protein intake in this study was not associated with stunting, wasting, overweight and obesity. Further investigation is needed on this topic.

Socioeconomic status affects food choices. This study examined the relationships between socioeconomic status (SES) and animal and plant protein intake in the Korean elderly population whose protein intake is insufficient. We used cross-sectional data from 3512 Koreans aged 60 years or older, who had participated in the Nutrition Survey of the 2013–14 Korea National Health and Nutrition Examination Survey (KNHANES). One day 24-h recall data was used to estimate the daily total, animal, and plant protein intake. Household income and educational attainment were assessed by trained interviewers. After making adjustment, household income was positively associated with animal protein intake with a statistical significance in females (p = 0.030) and with a marginal significance in males (p = 0.069). However, plant protein intake did not show any significant association. In both sexes, educational attainment was positively associated with animal protein intake (p = 0.007 for males, p = 0.001 for females). Association of educational attainment with plant protein intake was negative in males (p = 0.037) and non-significant in females. (p = 0.945). High SES was associated with higher total protein intake and animal protein intake in the Korean elderly. Health policies and nutrition education are needed to improve protein intake of the vulnerable Korean elderly with low SES.

ABSTRACT Research supports the hypothesis that higher total protein intake during weight loss promotes retention of lean soft tissue, but the effect of dietary protein quantity on bone mass, a lean hard tissue, is inconsistent. The purpose of this systematic review and meta-analysis was to assess the effect of dietary protein quantity [higher protein (HP): ≥25% of energy from protein or ≥1.0 g · kg body wt–1 · d–1; normal protein (NP): <25% of energy from protein or <1.0 g · kg body wt–1 · d–1] on changes in bone mineral density (BMD) and content (BMC; total body, lumbar spine, total hip, femoral neck) following a prescribed energy restriction. We hypothesized that an HP diet would attenuate the loss of BMD/BMC following weight loss in comparison to an NP diet. Two researchers systematically and independently screened 2366 publications from PubMed, Cochrane, Scopus, CINAHL, and Web of Science Core Collection and extracted data from 34 qualified publications. Inclusion criteria included the following: 1) healthy subjects ≥19 y; 2) a prescribed energy restriction; 3) measurements of total protein intake, BMD, and BMC; and 4) an intervention duration of ≥3 mo. Data from 10 of the 34 publications with 2 groups of different total protein intakes were extracted and used to conduct a random-effects model meta-analysis. A majority of publications (59%) showed a decrease in bone quantity following active weight loss, regardless of total protein intake. Statistically, the loss of total BMD (P = 0.016; weighted mean difference: +0.006 g/cm2; 95% CI: 0, 0.011 g/cm2) and lumbar spine BMD (P = 0.019; weighted mean difference: +0.017 g/cm2; 95% CI: 0.001, 0.033 g/cm2) was attenuated with an HP versus an NP weight-loss diet. However, the clinical significance is questionable given the modest weighted mean difference and study duration. Higher total protein intake does not exacerbate but may attenuate the loss of bone quantity following weight loss.
