Impact of high energy oral nutritional supplements consumed in the late afternoon on appetite, energy intake and cardio-metabolic risk factors in females with lower BMI

Lipid-based Nutritional Supplement Impact on Energy Intake, Appetite, Glucose and Insulin Levels in Under-Weight Pregnant and Lactating Women with Preeclampsia

OBJECTIVE

To investigate the response of nutritional supplement (LNS-PLW) on appetite score, energy intake, insulin and glucose levels in preeclamptic women.

DESIGN & PARTICIPANTS

Sixty under-weight preeclamptic primigravida were divided into two groups randomly and provided LNS-PLW/Placebo in the fasted state. Blood samples were collected at fasting state, after 30mins of supplementation, "ad libitum buffet" breakfast and lunch for glucose and insulin levels.

RESULTS

Total energy intake was higher significantly in the LNS-PLW group, although during breakfast it was significantly reduced. The insulin and glucose concentration was significantly increased after 30min of supplementation in the LNS-PLW group.

CONCLUSION

Intake of the LNS-PLW by pre-eclamptic women had short-term suppression on subsequent meal but improved total energy intake during trial.

A multi-center prospective study of plant-based nutritional support in adult community-based patients at risk of disease-related malnutrition

Introduction

There is an emerging need for plant-based, vegan options for patients requiring nutritional support.

Methods

Twenty-four adults at risk of malnutrition (age: 59 years (SD 18); Sex: 18 female, 6 male; BMI: 19.0 kg/m2 (SD 3.3); multiple diagnoses) requiring plant-based nutritional support participated in a multi-center, prospective study of a (vegan suitable) multi-nutrient, ready-to-drink, oral nutritional supplement (ONS) [1.5 kcal/mL; 300 kcal, 12 g protein/200 mL bottle, mean prescription 275 mL/day (SD 115)] alongside dietary advice for 28 days. Compliance, anthropometry, malnutrition risk, dietary intake, appetite, acceptability, gastrointestinal (GI) tolerance, nutritional goal(s), and safety were assessed.

Results

Patients required a plant-based ONS due to personal preference/variety (33%), religious/cultural reasons (28%), veganism/reduce animal-derived consumption (17%), environmental/sustainability reasons (17%), and health reasons (5%). Compliance was 94% (SD 16). High risk of malnutrition ('MUST' score ≥ 2) reduced from 20 to 16 patients (p = 0.046). Body weight (+0.6 kg (SD 1.2), p = 0.02), BMI (+0.2 kg/m2 (SD 0.5), p = 0.03), total mean energy (+387 kcal/day (SD 416), p < 0.0001) and protein intake (+14 g/day (SD 39), p = 0.03), and the number of micronutrients meeting the UK reference nutrient intake (RNI) (7 vs. 14, p = 0.008) significantly increased. Appetite (Simplified Nutritional Appetite Questionnaire (SNAQ) score; p = 0.13) was maintained. Most GI symptoms were stable throughout the study (p > 0.06) with no serious adverse events related.

Discussion

This study highlights that plant-based nutrition support using a vegan-suitable plant-based ONS is highly complied with, improving the nutritional outcomes of patients at risk of malnutrition.

Recommending ultra-processed oral nutrition supplements for unintentional weight loss: Are there risks?

Oral nutrition supplements (ONS) are widely recommended for the management of unintentional weight loss in patient populations, long-term care residents, and community-dwelling older adults. Most marketed ONS are ultra-processed, with precision nutrition and aseptic composition, as well as convenience and availability, driving their selection. However, therapeutic effectiveness is mixed and the potential health risks of consuming ultra-processed ONS long-term in lieu of less-processed foods have received little attention. A diverse and balanced microbiota supporting immunity and wellness is maintained by a diet rich in plant-sourced foods. The implications of ultra-processed ONS displacing plant-sourced foods, and specifically the potential for undesirable impacts on the gut microbiota, require consideration. Most ONS are either devoid of fiber or are supplemented with isolated or purified fibers that may contribute to adverse gastrointestinal symptoms and appetite suppression. In contrast, the diversity of microbial-available, nondigestible carbohydrates, together with the array of phytochemicals found in plant-sourced foods, support microbial diversity and its resiliency. This review outlines the clinical dilemma of recommending commercial ultra-processed ONS vs nutritionally adequate (eg, high-energy/high-protein) foods and beverages that contribute to diet quality, maintenance of a diverse and stable gut microbiota composition, and support nutrition status and health. Ultra-processed ONS may fall short of expected health benefits, and overreliance may potentially contribute to the risk for patient and older adult populations because of the displacement of a variety of healthful foods.
