Abstract
The health and environmental advantages of plant-predominant diets will likely lead to increasing numbers of consumers reducing their reliance on animal products. Consequently, health organizations and professionals will need to provide guidance on how best to make this change. In many developed countries, nearly twice as much protein is derived from animal versus plant sources. Potential benefits could result from consuming a higher share of plant protein. Advice to consume equal amounts from each source is more likely to be embraced than advice to eschew all or most animal products. However, much of the plant protein currently consumed comes from refined grains, which is unlikely to provide the benefits associated with plant-predominant diets. In contrast, legumes provide ample amounts of protein as well other components such as fiber, resistant starch, and polyphenolics, which are collectively thougt to exert health benefits. But despite their many accolades and endorsement by the nutrition community, legumes make a negligible contribution to global protein intake, especially in developed countries. Furthermore, evidence suggests the consumption of cooked legumes will not substantially increase over the next several decades. We argue here that plant-based meat alternatives (PBMAs) made from legumes are a viable alternative, or a complement, to consuming legumes in the traditional manner. These products may be accepted by meat eaters because they can emulate the orosensory properties and functionality of the foods they are intended to replace. PBMAs can be both transition foods and maintenance foods in that they can facilitate the transition to a plant-predominant diet and make it easier to maintain. PBMAs also have a distinct advantage of being able to be fortified with shortfall nutrients in plant-predominant diets. Whether existing PBMAs provide similar health benefits as whole legumes, or can be formulated to do so, remains to be established. Adv Nutr 2023;xx:xx-xx.

Abstract
Nutrient fortifiers are added to human milk to support the development of very-low-birth-weight infants. Currently, bovine-milk-based fortifiers (BMBFs) are predominantly administered, with increasing interest in adopting human-milk-based fortifiers (HMBFs). Although beneficial for growth, their effects on the gastrointestinal microbiota are unclear. This triple-blind, randomized clinical trial (NCT02137473) tested how nutrient-enriching human milk with HMBF versus BMBF affects the gastrointestinal microbiota of infants born < 1,250 g during hospitalization. HMBF-fed infants (n = 63, n = 269 stools) showed lower microbial diversity, altered microbial community structure, and changes in predicted microbial functions compared with BMBF-fed infants (n = 56, n = 239 stools). HMBF-fed infants had higher relative and normalized abundances of unclassified Enterobacteriaceae and lower abundances of Clostridium sensu stricto. Post hoc analyses identified dose-dependent relationships between individual feed components (volumes of mother's milk, donor milk, and fortifiers) and the microbiota. These results highlight how nutrient fortifiers impact the microbiota of very-low-birth-weight infants during a critical developmental window.

Abstract
Infants born preterm or low birth weight are at risk for morbidity, mortality and later neuroimpairment. Appropriate early post-natal growth is associated with better outcomes in-hospital and post-discharge. Therefore, nutritional strategies that support growth may improve the long-term health of this population. Mother's milk with donor milk as a supplement are preferred sources of nutrition for these infants but may not always support growth, especially amongst infants born of very low birth weight (<1500 g) and or those with a major morbidity. Systematic reviews of randomised controlled trials to date demonstrate that multi-nutrient fortification of human milk improves in-hospital growth of preterm infants although data on long-term neurodevelopment are lacking. Further, individualised approaches to fortification based on milk analysis or the infant's metabolic response may improve growth over standard fortification. The evidence is insufficient to inform the timing of introducing fortifier, routine fortification of feeds post-discharge or routine use of fortifiers made from human instead of bovine milk. Importantly, there is insufficient data to determine if these fortification practices improve relevant clinical or neurodevelopmental outcomes. In sum, there is an urgent need for well-designed clinical trials to assess potential benefits and risks of fortification practices and at what cost.

Abstract
BACKGROUND Extrauterine growth restriction (EUGR) in preterm infants is associated with higher morbidity and impaired neurodevelopment. Early nutrition support may prevent EUGR in preterm infants, but it is not known if this improves organ development and brain function in the short and long term. OBJECTIVE Using pigs as models for infants, we hypothesized that diet-induced EUGR impairs gut, immunity, and brain development in preterm neonates during the first weeks after birth. METHODS Forty-four preterm caesarean-delivered pigs (Danish Landrace × Large White × Duroc, birth weight 975 ± 235 g, male:female ratio 23:21) from 2 sows were fed increasing volumes [32-180 mL/(kg·d)] of dilute bovine milk (EUGR group) or the same diet fortified with powdered bovine colostrum for 19 d (CONT group, 50-100% higher protein and energy intake than the EUGR group). RESULTS The EUGR pigs showed reduced body growth (-39%, P < 0.01), lower plasma albumin, phosphate, and creatine kinase concentrations (-35 to 14%, P < 0.05), increased cortisol and free iron concentrations (+130 to 700%, P < 0.05), and reduced relative weights of the intestine, liver, and spleen (-38 to 19%, all P < 0.05). The effects of EUGR on gut structure, function, microbiota, and systemic immunity were marginal, although EUGR temporarily increased type 1 helper T cell (Th1) activity (e.g. more blood T cells and higher Th1-related cytokine concentrations on day 8) and reduced colon nutrient fermentation (lower SCFA concentration; -45%, P < 0.01). Further, EUGR pigs showed increased relative brain weights (+19%, P < 0.01), however, memory and learning, as tested in a spatial T-maze, were not affected. CONCLUSION Most of the measured organ growth, and digestive, immune, and brain functions showed limited effects of diet-induced EUGR in preterm pigs during the first weeks after birth. Likewise, preterm infants may show remarkable physiological adaptation to deficient nutrient supply during the first weeks of life although early life malnutrition may exert negative consequences later.

Abstract
Beta-carotene (BC) degradation was studied by liquid chromatography coupled to a quadrupole time of flight mass spectrometer. Throughout/After 21 days of dark storage, 56 nonvolatile degradants were chromatographically separated from pure BC crystal and their molecular formulas were identified. Their structure information was gained by comparing the fragments to a different, but structure-related compound. For example, a newly formed double bond position in dehydrogenated BC was determined by comparing the fragments between BC and dehydrogenated BC. One of their chemical structures was confirmed by comparing its precursor ion mass, retention time, isotopic ratio, and fragmentation to a pure trans-beta-apo-8'-apocarotenal. BC cleavage was observed on double bonds as well as single bonds in BC conjugation chain. PRACTICAL APPLICATION: As evidenced in this study, beta-carotene (BC) degradation is a spontaneous process initiated when the compound is exposed to air. The stoichiometric ratio of BC to oxygen is 1:0.03 at the first oxidation, therefore, only 0.3 mg oxygen or 1.2 mL air will degrade 10 mg BC, an average daily recommended intake. Not like in enzymatic BC degradation, spontaneous BC oxidation did not produce provitamin A, either in retina C20H38O or retinol C20H40O forms. For BC application in vitamin A deficiency, spontaneous BC oxidation should be avoided.

Abstract
BACKGROUND Fortification of donor human milk (DHM) is required for optimal growth of very preterm infants, but there are concerns of more gut dysfunction and necrotizing enterocolitis (NEC) when using formula-based fortifiers (FFs), especially soon after birth. Intact bovine colostrum (BC) is rich in nutrients and bioactive factors, and protects against NEC in preterm pigs. We hypothesized that fortification of DHM with BC is superior to FFs to prevent gut dysfunction and infections when provided shortly after preterm birth. METHODS Two FF products, Enfamil (ENF; intact protein, vegetable oil) and PreNAN+Nutrilon (NAN; extensively hydrolyzed protein, maltodextrin), were compared with BC as fortifier to DHM fed to preterm pigs for 5 days. RESULTS Relative to the DHM+BC group, DHM+FF groups had higher diarrhea score and lower hexose uptake and lactase activity, and specifically the DHM+NAN group showed higher gut permeability, NEC score, more mucosa-adherent bacteria with altered gut microbiota structure (ie, lower diversity, increased Enterococcus, decreased Staphylococcus abundance). Both DHM+FF groups showed higher expression of intestinal cytokine and inflammation-related genes, more gut-derived bacteria in the bone marrow, lower density of mucin-containing goblet cells, and slightly higher colon lactate, stomach pH and acetate, and blood neutrophil-to-lymphocyte levels than the DHM+BC group. CONCLUSIONS Used as a fortifier to DHM, BC is superior to FFs to support gut function, nutrient absorption, and bacterial defense mechanisms in preterm pigs. It is important to optimize the composition of nutrient fortifiers for preterm infants fed human milk.

Abstract
Mother's own milk is the optimal first diet for preterm infants, but donor human milk (DM) or infant formula (IF) is used when supply is limited. We hypothesized that a gradual introduction of bovine colostrum (BC) or DM improves gut maturation, relative to IF during the first 11 days after preterm birth. Preterm pigs were fed gradually advancing doses of BC, DM, or IF (3-15 ml·kg(-1)·3 h(-1), n = 14-18) before measurements of gut structure, function, microbiology, and immunology. The BC pigs showed higher body growth, intestinal hexose uptake, and transit time and reduced diarrhea and gut permeability, relative to DM and IF pigs (P < 0.05). Relative to IF pigs, BC pigs also had lower density of mucosa-associated bacteria and of some putative pathogens in colon, together with higher intestinal villi, mucosal mass, brush-border enzyme activities, colonic short chain fatty acid levels, and bacterial diversity and an altered expression of immune-related genes (higher TNFα, IL17; lower IL8, TLR2, TFF, MUC1, MUC2) (all P < 0.05). Values in DM pigs were intermediate. Severe necrotizing enterocolitis (NEC) was observed in >50% of IF pigs, while only subclinical intestinal lesions were evident from DM and BC pigs. BC, and to some degree DM, are superior to preterm IF in stimulating gut maturation and body growth, using a gradual advancement of enteral feeding volume over the first 11 days after preterm birth in piglets. Whether the same is true in preterm infants remains to be tested.

Abstract
BACKGROUND Under-nutrition in older adults is widespread. Oral nutritional supplement beverages (ONS) are prescribed, yet consumption by older people is often insufficient. A variety of supplement formats may improve nutrient intake. This study developed protein and micro-nutrient fortified biscuits and evaluated their sensory attributes and liking by older people. Two micro-nutrient strategies were taken, to match typical ONS and to customise to the needs of older people. RESULTS Oat biscuits and gluten-free biscuits developed contained over 12% protein and over 460 kcal 100 g(-1). Two small (40 g) biscuits developed to match ONS provided approximately 40% of an ONS portion of micro-nutrients and 60% of macro-nutrients; however, the portion size was considered realistic whereas the average ONS portion (200 mL) is excessive. Biscuits developed to the needs of older adults provided, on average, 18% of the reference nutrient intake of targeted micro-nutrients. Sensory characteristics were similar between biscuits with and without micro-nutrient fortification, leading to no differences in liking. Fortified oat biscuits were less liked than commercial oat biscuits, partly attributed to flavour imparted by whey protein fortification. CONCLUSION Macro- and micro-nutrient fortification of biscuits could provide an alternative fortified snack to help alleviate malnutrition in older adults.
