Abstract

A synthetic nutritional composition comprises milk fat globule membrane (MFGM) in the range of about 10 µg/100 kcal to about 1500 mg/100kcal for use in improving neurological development in a paediatric subject. The synthetic nutritional composition is administered to the paediatric subject for at least three months during the first year of life and administration of the synthetic nutritional composition improves neurological development of the paediatric subject from at least two years of age. The administration of the composition may take place for at least six months during the first year of life. Preferably, the improvement in neurological development is an improvement in cognitive development, such as development of memory, verbal comprehension, visual spatial ability, fluid reasoning, mental processing speed, rule learning, executive function and language acquisition. The improvement may persist until at least five years of age. The MFGM may be provided in an enriched milk product.

Description

Use of Milk Fat Globule Membrane

Field of the Invention

[0001] The present application relates to a synthetic nutritional composition comprising milk fat globule membrane (MFGM) for use in improving neurological development in a paediatric subject, comprising the step of administering to the subject a synthetic nutritional composition comprising milk fat globule membrane (MFGM). More particularly, the present application relates to a synthetic nutritional composition comprising MFGM in the range of about 10 pg/100 kcal to about 1500 mg/100 kcal for use in improving neurological development in a paediatric subject, wherein the synthetic nutritional composition is administered to the paediatric subject for at least three months during the first year of life, and wherein said administration of the synthetic nutritional composition improves neurological development of the paediatric subject from at least two years of age.

Background

[0002] Human milk contains a number of components that contribute to the growth and development of the brain in infants. Observational studies of infant cognitive function have shown an advantage for breastfed infants over formula-fed infants, even after control for socioeconomic factors. Changes in infant formula to better match the dynamic features of breast milk have brought the composition, functionality, and health-based outcomes closer together for infants receiving human milk or infant formula.

[0003] Synthetic nutritional compositions for human consumption based on bovine dairy products are, typically, made using skimmed milk powder as the predominant dairy component. Skimmed milk powder contains small quantifies of bioactive components such as phospholipids, sphingolipids and gangliosides. Some of these bioactive components have been shown to have a profound and lasting impact on human brain function, particularly on the brain function of infants whilst they are developing. Whilst skimmed milk powder contains these beneficial bioactive components, they are only present in small quantities which would not be sufficient to provide the desired benefits to human brain function.

[0004] A number of these bioactive components are present within milk fat globule membrane (MFGM). MFGM is a naturally occurring bioactive membrane structure that surrounds the fat droplets in human milk and other mammalian milk e.g. cow's milk. MFGM is comprised of a trilayer lipid structure that comprises a complex mixture of phospholipids (such as phosphatidylethanolamine, phosphatidylcholine, phosphatidylserine, and phosphatidylinositol), glycolipids, glycosphingolipids (such as sphingomyelin and gangliosides), other polar lipids, proteins, glycoproteins (such as xanthine dehydrogenase, xanthine oxidase, lactadherin, fatty acid binding proteins (FABPs), mucin-1, butyrophilins, adipophilin, and cluster of differentiation 36 (CD36)), triglycerides, cholesterol, 7-dehydrocholesterol, enzymes, and other components.

[0005] There are reports of benefits in neurological development in paediatric subjects of 12-18 months of age through supplementation of infant formula with MFGM during the first year of life.

[0006] Timby et al., Am J Clin Nutr 2014; 99:860-8 reports a study wherein infants were fed an experimental formula with added MFGM (EF) or a standard formula (SF) until six months of age. At 12 months of age, the cognitive score on testing with the Bayley Scales of Infant and Toddler Development, Third edition ("Bayley-III"), was higher in the EF group than in the SF group and not significantly different from that in the reference breast-fed group of infants.

[0007] Li et al., J Pediatr 2019, 215, 24-31 reports a study wherein infants were fed an infant formula with added MFGM and lactoferrin (MFGM + Lf) or a standard cows' milk-based infant formula (control) until six months of age. The primary outcome was the Bayley-III cognitive score at day 365 (i.e. 12 months of age). At 12 months of age, the cognitive score on testing with Bayley-III was higher in the MFGM + Lf group than in the control group. However, no group differences were detected in any Bayley-III domain (cognitive, language and motor) at day 545 of life (i.e. 18 months of age), although scores of some subcategories of the MacArthur-Bates Communicative Development Inventories were higher (p < 0.05) in the MFGM + Lf group. The MFGM + Lf group achieved higher scores compared to the control group at 18 months of age in sentence complexity (using words in longer and more grammatically correct combinations) and two categorical items: absent owners (naming an absent person to whom a visible object belongs) and Chinese classifiers (grammatical marker specific to Chinese language).

[0008] It is desirable to provide synthetic nutritional compositions for administration to paediatric subjects of up to 12 months of age that provide neurological benefits which persist beyond 12 months or even 18 months of age.

Detailed Description

[0060] The inventors have surprisingly found that administration of a synthetic nutritional composition comprising MFGM for at least three months during the first year of life improves neurological development in the paediatric subject later on in childhood, i.e. when the paediatric subject is at least two years of age.

[0061] As discussed above, it has previously been shown in Timby at at 2014 that supplementation with MFGM in the first year of life has effects at 12 months of age and Li at a/. 2019 shows that the addition of MFGM and lactoferrin to synthetic nutritional compositions, which are administered in the first year of life, has effects at 12 months of age and limited effects at 18 months of age.

[0062] As detailed in Example 1, the inventors conducted a follow-up study to the study detailed in Li et a/. 2019 on participants aged between 5.5 and 6 years of age who completed study feeding during the first year of life (i.e. through day 365 of age). The inventors surprisingly found that feeding infants formula with added MFGM and lactoferrin through 12 months of age led to improved neurological development (relative to the control group) later in life between 5.5 and 6 years of age. The results suggest that the addition of MFGM and lactoferrin to infant formula has persistent effects in supporting neurological development during childhood.

[0063] Although the test formula in Example 1 included both MFGM and lactoferrin, there is clinical evidence that MFGM and components thereof support the development of language and cognitive domains (Li et a/. (2019)).

[0064] A significant body of preclinical data have demonstrated that MFGM, or components thereof, including sphingomyelin, gangliosides, phosphafidylserine and phosphatidylcholine, play roles in neural development and function, gastrointestinal immune defence and gut health. Glycosylated proteins (mucin-1, mucin-15, butyrophilin, and lactadherin) and glycosylated sphingolipids from MFGM may promote the development of healthy infant gut microbiota by favouring beneficial Bifidobacterium species (Bourlieu et al., Current Opinion in Clinical Nutrition and Metabolic Care: March 2015, 18(2), 118-127).

[0065] Clinical reports also suggest that MFGM and components thereof may affect brain function directly. For example, a nutritional intervention via administration of sphingomyelin-fortified milk has a positive association with the neurodevelopment of lowbirth-weight-infants (Tanaka et al. (2013), Brain & Development, 35(1), 45-52).

[0066] Therefore, it is hypothesised that similar neurological benefits to those observed in Example 1 would also be observed in the absence of lactoferrin.

[0067] This is supported by the results for the clinical study detailed in Example 2. As discussed in Example 2, the inventors found that infants who received infant formula with added MFGM during the first year of life showed a lower event-related potential (ERP) amplitude at two years of age, compared to both infants who received a standard formula and the breastfed infant control group. The lower ERP potential amplitudes observed in the MFGM group may reflect a higher degree of maturation of neural circuits. The inventors also found that the MFGM group at two years of age showed a lower ERP latency for a subset of stimuli (native unfamiliar stimuli), which may suggest improved myelination.

[0068] Therefore, the administration of synthetic nutritional compositions with added MFGM during the first year of life, on the basis of improved neural maturation and myelinafion, may have a higher likelihood of achieving improved neurodevelopmental outcomes at older ages, as illustrated by the results presented in Example 2.

[0069] The finding that the effects of MFGM, optionally in the presence of lactoferrin, persist later in childhood was unexpected based on the Timby etal. 2014 and Li et al. 2019 studies. The Timby et all 2014 study did not measure neurological development beyond 12 months of age. As noted by the authors of Li et a/. (2019), the observation that few group differences in neurological outcomes were detected at 18 months could indicate that the control group caught up developmentally and the earlier advantages observed in the MFGM + Lf group were not sustained. Whilst differences in certain language subcategories were observed at day 545, notably no differences were detected at day 365. The authors postulated that the differences in Bayley-III domains at day 365 and certain language subcategories at day 545 may be indicative of a developmental cascade (Masten AS, Cicchetfi D. Developmental cascades. Dev Psychopathol. 2010; 22:491-5).

[0070] To the best of the inventors' knowledge, the discovery that the addition of MFGM to synthetic nutritional compositions, which are administered in the first year of life, enhances neurological development in paediatric subjects from two years of age has not previously been shown and certainly could not be predicted by the results of Timby et al. 2014 or Li et a/. 2019.

[0071] The present invention therefore provides a synthetic nutritional composition comprising milk fat globule membrane (MFGM) in the range of about 10 pg/100 kcal to about 1500 mg/100 kcal for use in improving neurological development in a paediatric subject, wherein the synthetic nutritional composition is administered to the paediatric subject for at least three months during the first year of life, and wherein said administration of the synthetic nutritional composition improves neurological development of the paediatric subject from at least two years of age.

[0072] The paediatric subject may be a neurologically healthy paediatric subject. For example, the administration of the synthetic nutritional composition comprising MFGM during the first year of life as defined above may promote the healthy establishment of cognitive function in the paediatric subject from at least two years of age.

[0073] The paediatric subject may instead be of compromised neurological health. For example, the improvement in neurological development according to the invention may be the repair of, or reduction in the severity of cognitive function impairment in the paediatric subject. The administration of the synthetic nutritional composition comprising MFGM during the first year of life may result in the treatment of disorders associated with the delayed establishment of cognitive function or cognitive function impairment in a paediatric subject from at least two years of age. Non-limiting examples of disorders include delayed and/or impaired learning ability, loss of, or poor development of executive functions, memory impairment and a delay in language development.

[0074] The improvement in neurological development in a paediatric subject is relative to the neurological development observed at the same age when a standard infant formula is administered, i.e. an infant formula which is not supplemented with MFGM.

[0075] The improvement in neurological development may be an improvement measured in a clinical setting following consumption of the composition in accordance with the present invention.

[0076] As explained above, the use of MFGM may result in a higher degree of maturation of neural circuits and/or improved myelination. This would translate into a fundamental benefit for brain development and normal brain function.

[0077] The improvement in neurological development may be an improvement in cognitive development.

[0078] The improvement in cognitive development may be an improvement measured by at least one standardised clinical neuropsychological test. Non-limiting examples include the Bayley Scales of Infant Development, 3rd or 4th editions 'Bayley-Ill" and "Bayley-IV").

[0079] The improvement in cognitive development may be selected from at least one of an improvement in the development of memory, verbal comprehension, visual spatial ability, fluid reasoning, mental processing speed, rule learning, executive function, language acquisition and summary or global intelligence quotient (IQ) score. Preferably, the improvement in cognitive development is selected from at least one of an improvement in the development of memory, verbal comprehension, visual spatial ability, fluid reasoning, mental processing speed, rule learning, executive function and language acquisition.

[0080] The improvement in the development of memory, verbal comprehension, visual spatial ability, fluid reasoning and/or mental processing speed may be an improvement measured by at least one standardised clinical neuropsychological test. A non-limiting example of a suitable neuropsychological test is the Wechsler Preschool & Primary Scale of Intelligence, Fourth Edition (WPPSI-IV).

[0081] Executive function is the ability to coordinate and integrate cognitive-perceptual processes in relation to time and space, determining how well a subject can recognise, evaluate and make a choice among a variety of alternative options and strategies. Skills that comprise executive function include attention, working memory, inhibitory control (e.g. rule learning) and cognitive flexibility.

[0082] The improvement in executive function may be an improvement measured by at least one standardised clinical neuropsychological test. Non-limiting examples of suitable neuropsychological tests are: Stroop Task Test -demonstrates rule learning and inhibitory control Dimensional Change Card Sort (DCCS) task -demonstrates rule learning and cognitive flexibility.

[0083] The improvement in language acquisition may be an improvement measured by at least one standard clinical neuropsychological test. Non-limiting examples include Bayley-III, Bayley-IV or auditory event-related potential measurements (Choudhury N, Benasich AA. Clin Neurophysiol: Official J Int Fed Clin Neurophysiol. 2011;122(2):320-38; Riva Vet al. Cereb Cortex. 2017;28(6):2100-8.).

The probiotic may be naturally-occurring, synthetic, or developed through the genetic manipulation of organisms, whether such source is now known or later developed.

[0141] The composition may comprise a viable probiotic in the range of about 1 x 104 colony forming units per 100 kilocalories (CFU/100 kcal) to about 1.5 x 1012 CFU/100 kcal.

Preferably, the composition comprises a viable probiotic in the range of about 1 x 106 CFU/100 kcal to about 1 x 102 CFU/100 kcal. More preferably, the composition comprises a viable probiotic in the range of about 1 x 107 CFU/100 kcal to about 1 x 108 CFU/100 kcal.

[0142] The composition may comprise p-glucan. Preferably, the p-glucan comprises p1,3-glucan. Preferably, the 13-1,3-glucan comprises 3-1,3;1,6-glucan. The composition may comprise p-glucan present in the range of about 0.010 grams to about 0.080 grams per 100g of composition. Alternatively, the composition may comprise p-glucan in the range of about 3 mg/100 kcal to about 17 mg/100 kcal. Preferably, the composition comprises p-glucan in the range of about 4 mg/100 kcal to about 17 mg/100 kcal.

[0143] The composition may comprise sialic acid. Mammalian brain tissue contains the highest levels of sialic acid as sialic acid is incorporated into brain-specific proteins, such as the neural cell adhesion molecule (NCAM) and lipids (e.g. gangliosides). Sialic acid is therefore believed to play an important role in neural development and function, learning, cognition, and memory.

[0144] The composition may comprise sialic acid provided by an inherent source (such as an enriched milk product), exogenous sialic acid, sialic acid from sources (such as cGMP), or any combination thereof. The composition may comprise sialic acid in the range of about 100 mg/L to about 800 mg/L. Preferably, the composition comprises sialic acid in the range of about 120 mg/L to about 600 mg/L. More preferably, the composition comprises sialic acid in the range of about 140 mg/L to about 500 mg/L. Alternatively, the composition may comprise sialic acid in the range of about 1 mg/100 kcal to about 120 mg/100 kcal.

Preferably, the composition comprises sialic acid in the range of about 14 mg/100 kcal to about 90 mg/100 kcal. More preferably, the composition comprises sialic acid in the range of about 15 mg/100 kcal to about 75 mg/100 kcal.

[0145] The synthetic nutritional composition may comprise one or more suitable composition ingredient, wherein the suitable composition ingredient comprises a vitamin, a mineral, choline, inositol, an emulsifier, a preservative, a stabiliser, or any combination thereof.

Minerals are usually added in salt form. The presence and amounts of specific minerals and other vitamins will vary depending on the intended consumer whether it is a child or an infant.

[0147] As noted above, the composition may comprise choline. Choline is a nutrient that is essential for normal function of cells. Choline is a precursor for membrane phospholipids and it accelerates the synthesis and release of acetylcholine, a neurotransmitter involved in memory storage. Without wishing to be bound by theory, it is believed that dietary choline and docosahexaenoic acid (DHA) act synergistically to promote the biosynthesis of phosphatidylcholine and thus, help promote synaptogenesis in human subjects.

Additionally, choline and DHA act synergistically to promote dendritic spine formation, which is important in the maintenance of established synaptic connections. The composition may comprise about 20 mg to about 100 mg of choline per 8f1. oz. (236.6 mL) serving.

[0148] As noted above, the composition may comprise inositol. The inositol may be present as exogenous inositol, inherent inositol, or a combination thereof.

Alternatively, the composition comprises inositol in the range of about 130 mg/L to about 300 mg/L.

[0149] The composition may comprise one or more emulsifier, as an emulsifier can increase the stability of the composition. The emulsifier may comprise, but is not limited to, egg lecithin, soy lecithin, alpha lactalbumin, monoglycerides, diglycerides, or any combination thereof.

[0150] The composition may comprise one or more preservative, as a preservative can extend the shelf-life of the composition. The preservative may comprise, but is not limited to, potassium sorbate, sodium sorbate, potassium benzoate, sodium benzoate, calcium disodium EDTA, or any combination thereof.

[0151] The composition may comprise one or more stabiliser, as a stabiliser can help preserve the structure of the composition. The stabiliser may comprise, but is not limited to, gum arabic, gum ghatti, gum karaya, gum tragacanth, agar, furcellaran, guar gum, gellan gum, locust bean gum, pectin, low methoxyl pectin, gelatine, microcrystalline cellulose, CMC (sodium carboxymethylcellulose), methylcellulose hydroxypropyl methyl cellulose, hydroxypropyl cellulose, DATEM (diacetyl tartaric acid esters of mono-and diglycerides), dextran, carrageenans, or any combination thereof.

[0152] The synthetic nutritional composition may be intended for a paediatric subject. The paediatric subject may be an infant or a child. The infant may be a vaginally-delivered infant. Alternatively, the infant may be an infant delivered by C-section.

[0153] The synthetic nutritional composition may comprise a nutritional supplement, a children's nutritional product, an infant formula, a human milk fortifier, a follow-up formula, a young child milk, or any other composition designed for an infant or a paediatric subject. The nutritional composition may be provided in any form known in the art. The nutritional composition may be provided in the form of a powder, a gel, a suspension, a paste, a solid, a liquid, a liquid concentrate, a reconstitutable powder, a reconstituted solution, or a ready-to-use product. The composition may be provided in an orally-ingestible form, wherein the orally-ingestible comprises a food, a beverage, a tablet, a capsule, or a powder.

[0154] Preferably, the synthetic nutritional composition is in the form of a reconstitutable powder, a reconstituted solution, or a ready-to-use product. Most preferably, the synthetic nutritional composition is provided in the form of a reconstitutable powder.

[0155] The synthetic nutritional composition may be expelled directly into a subject's intestinal tract. The synthetic nutritional composition may be expelled directly into the gut.

The composition may be sucrose-free. The composition may also be lactose-free. The composition may not contain any medium-chain triglyceride oil. No carrageenan may be present in the composition. The composition may be free of all gums.

[0157] The scope of the present invention is defined in the appended claims. It is to be understood that the skilled person may make amendments to the scope of the claims without departing from the scope of the present disclosure.

[0158] The foregoing detailed description has been provided by way of explanation and illustration, and is not intended to limit the scope of the appended claims. Many variations in the presently preferred embodiments illustrated herein will be apparent to one of ordinary skill in the art, and remain within the scope of the appended claims and their equivalents.

Results are presented for infants who received infant formula up to 12 months of age (SF and EF) and a reference group of infants exclusively receiving human milk (NM). Figure 1A illustrates the overall P1 Amplitude (native familiar stimuli, native unfamiliar stimuli and foreign stimuli combined) by group. Figure 1B illustrates the overall P1 Latency by group. Figure 1C illustrates the P1 Latency in response to native unfamiliar stimuli (NUS) by group.

[0161] The present invention will now be described in relation to the following non-limiting

Examples.

Experimental Section Example 1 -Follow-Up Study [0162] The inventors then conducted a follow-up study to the study detailed in Li et al., J Pediatr 2019, 215, 24-31 on the participants who completed study feeding through day 365.

[0163] 292 participants were eligible to take part in the follow-up study (Control: 148, MFGM + Lf: 144). 116 participants of between 5.5 to 6 years of age enrolled and completed follow-up assessments (Control: 59, MFGM + Lf: 57). Follow-up assessments were carried out as outlined below.

Wechsler Preschool & Primary Scale of Intelligence [0164] The Wechsler Preschool & Primary Scale of Intelligence (4th Edition; WPPSI-IV, adapted for the Chinese population) was carried out for each participant. The primary outcome was a standardized IQ test for ages 4 years 0 months to 6 years 11 months and secondary outcomes were Verbal Comprehension (VC), Visual Spatial (VS), Fluid Reasoning (FR), Working Memory (VVM) and Processing Speed (PS). Composite scores for each variable were analysed separately by Analysis of Variance (ANOVA) to adjust for variables including study group, site, and sex and by Analysis of Covariance (ANCOVA) post-hoc to adjust for additional participant and family demographic variables (number of family members in the household, monthly average family income, mother and father highest education, years of early education completed prior to primary school and exposure to smoking in the home). The results are detailed in Table 1.

IQ

[0165] The Full-Scale IQ, Visual Spatial, and Processing Speed composite scores from the WPPSI-IV were significantly higher for MFGM + Lf vs the Control group. Other composite scores were also higher for MFGM + Lf vs the Control group, but not significantly so.

Stroop Task [0166] The Stroop Task measures inhibitory control and rule learning. The task involved inhibiting congruous responses to simple stimuli and providing an incongruous response.

Two forms of this task were completed: (i) banana = red, apple = yellow and (ii) sun = night, moon = day. Each participant carried out 16 trials and the outcome variable was the number of correct recitations. The scores were analysed by a repeated measures mixed-model including study group, site, sex, and task.

[0167] The Stroop Task scores (mean± SE) were significantly higher in the MFGM + Lf group compared to the Control group (15.6 ± 0.4 vs 13.2 ± 0.4; p<0.001).

Dimensional Change Card Sort (DCCS) task [0168] The DCCS task measures rule learning and flexibility in cognitive reasoning in three sequential phases: * Pre-switch phase (6 trials): child sorts multidimensional stimuli (coloured shapes) based on colour; * Post-switch phase (6 trials): sort same stimuli based on shape; and * Border phase (12 trials): sort criterion is based on border presence (Le border present = colour, border absent = shape).

[0169] The outcome variable was the number of correct answers. Scores were analysed by ANOVA including study group, site, and sex. The highest phase passed was analysed by Cochran-Mantel-Haenszel stratified by site and sex.

[0170] On the DCCS Task, there were no differences on pre-or post-switch phase scores, but the MFGM + Lf group had higher scores (7.4 ± 0.27) than Control (6.5 ± 0.28) in the border phase (p = 0.013).

[0171] Significant group differences were also detected in the highest phase passed (p = 0.039); border was the highest phase passed for more children in the MFGM + Lf group (18, 32%) compared to the Control group (7, 12%), whereas passing both pre-and post-switch was the highest phase achieved for more children in the Control group (49, 83%) compared to the MFGM + Lf group (36, 63%).

Child Behaviour Checklist [0172] A child behaviour checklist was carried out, which is a parent report measure used to detect behavioural and emotional problems in children and adolescents. No difference 15 was observed between the groups.

Conclusions

[0173] The inventors found that feeding infants formula with MFGM and Lf through 12 months of age led to improved neurological outcomes (relative to the control group) later in life between 5.5 and 6 years of age. The results suggest that the addition of MFGM and Lf to infant formula has persistent effects in supporting neurological development during childhood. Similar results to those observed in the follow-up study of Example 1 are expected in the absence of lactoferrin.

Example 2 -Clinical Study [0174] A double-blind, randomised, controlled trial was carried out at the Institute of Nutrition and Food Technology (INTA) at the University of Chile. The protocol and the informed consent forms were approved by the Institutional Review Board of INTA.

Participants were randomised to an experimental formula (EF) and a control formula (SF). A reference group of infants receiving human milk (HM) was also enrolled.

[0175] Infants eligible for randomisation to study formula were consuming infant formula as the sole source of nutrition for at least 48 hours prior to randomisation.

[0176] Infants eligible for the Human Milk Reference group were consuming mother's own breast milk as the exclusive source of nutrition with the intent to feed mother's own breast milk through approximately 180 days of age.

[0177] Additional inclusion criteria for all infants were: * Singleton birth; * Up to 120 days of age at study registration or randomisation; * Birth weight between 2500 to 4500 g; * Gestational age between 37 and 42 weeks; * History of normal growth (weight between and inclusive of the 10th and 90th percentiles on the WHO growth chart [28]); and * parents agreed not to enrol the infant in another interventional study and signed informed consent.

[0178] The exclusion criteria included: * use of complementary feeding; * history of underlying endocrine, metabolic, or chronic diseases, congenital malformation, or any other condition that could interfere with the ability of the infant to ingest food, or to have normal growth and development; 20 * evidence * of feeding difficulties or formula intolerance; * immunodeficiency; and * maternal illiteracy.

[0179] The experimental formula and the standard formula are shown below in Table 2.

The sources of protein for the EF were skimmed milk, WPC and whey protein-lipid concentrate (5 g/L, source of bovine MFGM; Lacprodan MFGM-10, Aria Foods Ingredients).

[0181] The sources of fat for both formulas were a base blend of palm olein, soybean, coconut, and high oleic sunflower oils, fungal-derived single cell oil (source of ARA) and algal-derived single cell oil (source of DHA). ARA is arachidonic acid and DHA is docosahexaenoic acid.

[0182] The sources of carbohydrate for both formulas were available carbohydrates (source: lactose, galactose, glucose, fructose, epilactose): 10.8 g; and prebiotic oligosaccharides: 0.6 g (4 g/L; source: prebiotic blend of polydextrose [PDX] and galactooligosaccharides [GOS; 1:1 ratio]) [0183] All infants were enrolled before 120 days of age and infants receiving infant formula were randomised to receive a standard cow's milk-based infant formula (SF) or a similar formula with added whey protein-lipid concentrate (5 g/L MFGM-10; source of bovine MFGM) (EF) through 12 months of age to assess growth and tolerance.

[0184] A total of 347 infants were randomised (SF, n = 174; EF, n = 173) and the reference group of infants exclusively receiving human milk was also enrolled (HM, n = 235).

Sound perception [0185] In a subset of participants (SF, n=42; EF, n=35; HM, n=45), neurophysiologic syllable sound perception was evaluated at day 730 of life (2 years of age).

[0186] Auditory event-related potential (ERP) data were collected by carrying out electroencephalographic recordings in children using a geodesic sensor net (128 scalp sites; Electric Geodesic, Inc., Eugene, Oregon, USA).

[0187] The stimuli used were consonant-vowel syllables. The native familiar stimulus (NFS; also referred to as a standard stimulus) was a consonant-vowel (CV) syllable phonetically relevant in Spanish (ta). Two CV syllables were used as deviants: a native unfamiliar stimulus (NUS; also referred to as a native deviant) (da) and a foreign stimulus (FS; also referred to as a non-native deviant) (sha). Stimuli were presented in a mismatch negativity (MMN) paradigm that contained a NFS (80%), a NUS (10%) and an FS (10%) for a total of 1000 stimuli.

[0188] The amplitude and latency of the P1 wave response (first wave that appears after the stimulus onset) in a time period of between 100 and 250 ms was analysed.

[0189] In general, P1 amplitude was significantly less for NFS wave response compared to the NUS wave response (1.88 ± 0.05 pV vs. 2.09 ± 0.06 pV, p < 0.004). P1 latency was also shorter for NFS compared to NUS (115.53 ± 1.16 ms vs 124.25 ± 0.89 ms, p<0.001). Overall, the inventors found that children at 24 months demonstrated differences in perception between familiar and unfamiliar auditory stimuli, the former being associated with lower ERP amplitude and shorter latency. This is to be expected for children at a young age. The differences in perception between familiar and unfamiliar auditory stimuli would be expected to decrease as language acquisition improves.

[0190] Figure 1A and 1B shows the amplitude and latency of the P1 wave response by feeding group. Overall P1 amplitude (native familiar stimuli, native unfamiliar stimuli and foreign stimuli combined) for the EF group was significantly lower compared to HM (1.81 ± 0.09 pV vs 2.1 ± 0.08 pV, p < 0.04) (Figure 1A). No significant differences in overall P1 latency were detected between feeding groups (Figure 1 B) . [0191] Figure 10 shows the P1 latency for native unfamiliar stimuli (NUS). As shown in Figure 10, the response to NUS was significantly different by study feeding group. P1 latency was significantly shorter for the EF (120.29 ± 10.4ms) compared to HM and SF groups (125.1 ± 9.5 ms, p< 0.03 and 127.36 ± 9.59 ms, p< 0.003, respectively).

[0192] Overall, the inventors found that infants who received infant formula enriched with MFGM during the first year of life showed a lower ERP amplitude at two years of age compared to the standard formula-fed infants and breastfed infants, which may reflect a higher degree of maturation of neural circuits. The inventors also found that infants who received infant formula enriched with MFGM during the first year of life showed a lower ERP latency for native unfamiliar stimuli at two years of age, which may suggest improved myelination.

Summary

[0193] The results in Examples 1 and 2 suggest that the addition of MFGM in infant formulas supports neurological development in healthy infants and young children.
