Nutritional Intake and Meal Composition of Patients Consuming Texture Modified Diets and Thickened Fluids: A Systematic Review and Meta-Analysis.

ABSTRACT: Texture-modified diets (TMDs) play an important role in ensuring safety for those with dysphagia but come with risks to nutrition and quality of life. The use of TMDs has been addressed with the increasing prevalence of dysphagia in previous decades. However, there is limited literature that investigates the nutrition perspectives of TMD consumers. This review summarises the nutrition outcomes of adults consuming TMDs and thickened fluids (TFs) and identifies the limitations of TMD and TF productions. A systematic database search following PICO criteria was conducted using Cochrane Central (via Ovid), MEDLINE, CINAHL, EMBASE, and Scopus databases. Nutrition intake, meal consumption, adequacy, and meal composition were identified as relevant outcomes. 35 studies were included for analysis. Consumption of TMDs demonstrated a poorer intake compared to regular diets, in particular significant in energy and calcium. Meta-analysis of mean differences showed favourable effects of shaped TMDs on both energy (-273.8 kJ/d; 95%CI: -419.1 to -128.6, p = 0.0002) and protein (-12.4 g/d; 95%CI: -17.9 to -6.8, p < 0.0001) intake compared to traditional cook-fresh TMDs. Nutrition intake was compromised in TMD consumers. Optimisation of nutrition intake was achievable through enrichment and adjusting meal texture and consistency. However, the heterogeneity of studies and the missing verification of the consistencies lead to difficulty in drawing conclusions regarding particular texture or intervention.

Project description:BackgroundPlant-based diets (PBDs) are increasingly recommended for human and planetary health. However, comprehensive evidence on the health effects of PBDs in children remains incomplete, particularly in vegans.ObjectivesTo quantify differences in body composition, cardiovascular risk, and micronutrient status of vegetarian and vegan children relative to omnivores and to estimate prevalence of abnormal micronutrient and cholesterol status in each group.MethodsIn a cross-sectional study, Polish children aged 5-10 y (63 vegetarian, 52 vegan, 72 matched omnivores) were assessed using anthropometry, deuterium dilution, DXA, and carotid ultrasound. Fasting blood samples, dietary intake, and accelerometry data were collected.ResultsAll results are reported relative to omnivores. Vegetarians had lower gluteofemoral adiposity but similar total fat and lean mass. Vegans had lower fat indices in all regions but similar lean mass. Both groups had lower bone mineral content (BMC). The difference for vegetarians attenuated after accounting for body size but remained in vegans (total body minus the head: -3.7%; 95% CI: -7.0, -0.4; lumbar spine: -5.6%; 95% CI: -10.6, -0.5). Vegetarians had lower total cholesterol, HDL, and serum B-12 and 25-hydroxyvitamin D [25(OH)D] without supplementation but higher glucose, VLDL, and triglycerides. Vegans were shorter and had lower total LDL (-24 mg/dL; 95% CI: -35.2, -12.9) and HDL (-12.2 mg/dL; 95% CI: -17.3, -7.1), high-sensitivity C-reactive protein, iron status, and serum B-12 (-217.6 pmol/L; 95% CI: -305.7, -129.5) and 25(OH)D without supplementation but higher homocysteine and mean corpuscular volume. Vitamin B-12 deficiency, iron-deficiency anemia, low ferritin, and low HDL were more prevalent in vegans, who also had the lowest prevalence of high LDL. Supplementation resolved low B-12 and 25(OH)D concentrations.ConclusionsVegan diets were associated with a healthier cardiovascular risk profile but also with increased risk of nutritional deficiencies and lower BMC and height. Vegetarians showed less pronounced nutritional deficiencies but, unexpectedly, a less favorable cardiometabolic risk profile. Further research may help maximize the benefits of PBDs in children.

Project description:ObjectiveGiven the importance of high sodium diets as a risk factor for disease burden (ranked 11(th) in importance in the Global Burden of Disease Study 2010), we aimed to determine the feasibility of low-sodium diets that were also low-cost, nutritious and (for some scenarios) included familiar meals.MethodsThe mathematical technique of "linear programming" was used to model eight optimized daily diets (some with uncertainty), including some diets that contained "familiar meals" for New Zealanders or were Mediterranean-, Asian- and Pacific-style diets. Data inputs included nutrients in foods, food prices and food wastage.FindingsUsing nutrient recommendations for men and a cost constraint of <NZ$9/d (US$6.84), the sodium intake levels in the eight optimized daily diets were all well below the 2300 mg/d (5.8 g salt/d) recommended maximum. The only diet to not consistently fall below the recommended "target" upper limit of 1600 mg/d included an evening meal with sausages (median=?1640 mg/d, 95% simulation interval: 1551-1735 mg/d). Many additional nutritional aspects of these optimized low-sodium diets suggest that they would reduce cardiovascular disease risk in other ways (e.g., improved polyunsaturated to saturated fat ratio) and also reduce risk of cancer and other chronic diseases (e.g., via higher intakes of vegetables, fruits and dietary fiber). Even healthier diets (e.g., with higher intakes of fruit) occurred when the cost constraint was relaxed to $NZ15/d (US$11.40). Similar results were obtained when the modeling considered diets for women.ConclusionsThese results provide some reassurance for the feasibility of substantially reducing population sodium intake given currently available low-cost foods and while maintaining some level of familiar meals. Policy makers could consider ways to promote such optimized diets and foods, including regulations on maximum salt levels in processed foods, and taxes on alternative foods that are high in salt, sugar and saturated fat.
