Effects of exercise and milk fat globule membrane (MFGM) supplementation on body composition, physical function, and hematological parameters in community-dwelling frail Japanese women: a randomized double blind, placebo-controlled, follow-up trial.

ABSTRACT:

Objective

To investigate the combined and separate effects of exercise and milk fat globule membrane (MFGM) supplementation on frailty, physical function, physical activity level, and hematological parameters in community-dwelling elderly Japanese women.

Methods

A total of 131 frail, elderly women over 75 years were randomly assigned to one of four groups: exercise and MFGM supplementation (Ex+MFGM), exercise and placebo (Ex+Plac), MFGM supplementation, or the placebo group. The exercise group attended a 60-minute training program twice a week for three months, and the MFGM group ingested 1g of the MFGM supplement in pill form, daily for 3 months. The primary outcome measure was change in frailty status based on Fried's frailty phenotype. Secondary outcome measures included body composition, physical function and hematological parameters, and interview survey components assessing lifestyle factors. Participants were followed for 4 months post-intervention.

Results

Significant group × time interactions were observed for usual walking speed (P = 0.005), timed up & go (P<0.001), and insulin-like growth factor-binding protein 3/insulin-like growth factor 1 ratio (P = 0.013). The frailty components revealed that weight loss, exhaustion, low physical activity, and slow walking speed were reversed, but low muscle strength did not significantly changed. Frailty reversal rate was significantly higher in the Ex+MFGM (57.6%) than in the MFGM (28.1%) or placebo (30.3%) groups at post-intervention (?2 = 8.827, P = 0.032), and at the follow-up was also significantly greater in the Ex+MFGM (45.5%) and Ex+Plac (39.4%) groups compared with the placebo (15.2%) group (?2 = 8.607, P = 0.035). The exercise+MFGM group had the highest odds ratio (OR) for frailty reversal at post-intervention and follow-up (OR = 3.12, 95% confidence interval (CI) = 1.13-8.60; and OR = 4.67, 95% CI = 1.45-15.08, respectively).

Conclusion

This study suggests that interventions including exercise and nutrition can improve frailty status. Statistically significant additive effects of MFGM with exercise could not be confirmed in this population, and further investigation in larger samples is necessary.

Project description:Milk fat globule membrane (MFGM), mainly comprising protein and fat, has been reported to have multiple biological functions for relieving intestinal inflammation and enhancing growth performance. We hypothesized that MFGM supplementation into sows' diet during late gestation can have a positive impact on the intestinal microecology of sows and their piglets, as well as on the growth of neonates. Therefore, the present study was conducted to investigate such effects and their potential mechanisms. Twenty-two pregnant sows were selected and randomly divided into the CON group (basal diet) and MFGM group (basal diet supplemented with 9.9 g per day MFGM). The feeding period began from d 85 of gestation and until farrowing. The concentrations of albumin (ALB), low-density lipoprotein cholesterol (LDL-C), and non-esterified fatty acids (NEFA) in plasma and short-chain fatty acids (SCFAs) in feces of sows from the MFGM group were determined. The concentrations of growth hormone (GH), immunoglobulin A (IgA), glucose (GLU), and NEFA in the umbilical cord blood in the MFGM group were significantly higher than those in the CON group. Piglets from the MFGM group showed improved growth performance, increased villus height in the jejunum, decreased crypt depth in the duodenum and jejunum, upregulated mRNA expressions of tight junctions (namely, Occludin; Claudin-1, Claudin-2, and Claudin-4; zonulin-1 (ZO-1)); mucins such as Mucin 2, Mucin 4, Mucin 13, and Mucin 20; and immune-related genes, such as tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ), interleukin-22 (IL-22), toll-like receptor 2 (TLR2), and toll-like receptor 4 (TLR4). In addition, the abundance of Prevotella in the feces of sows at farrowing and the abundance of Christensenellaceae_R-7_group in the feces of 21 day-old piglets from the MFGM group were significantly higher. Further correlation analysis revealed that the Christensenellaceae_R-7_group was positively correlated with the relative mRNA expressions of Occludin, Claudin-1, Claudin-2, Claudin-4, Mucin 13, TLR2, and TLR4. In conclusion, MFGM supplementation during late gestation improved the physiological status of sows by improving their plasma parameters and intestinal microecology. The improved provision of nutrients through the umbilical cord blood and optimized microbiota colonization in neonatal piglets were beneficial to the intestinal morphological structure and barrier functions, consequently improving the growth performance of neonates during lactation. These findings provide insights into the future applications of MFGM with regard to maternal-fetal nutrition and a new option for nutritional intervention of neonates through maternal dietary manipulation.

Project description:Impaired intestinal mucosal integrity and immunity are frequently observed in low-birth-weight (LBW) animals, which lead to inadequate growth and high neonatal mortality. However, the mechanisms of intestinal dysfunction in LBW animals are still unclear. Milk fat globule membrane (MFGM), a protein-lipid complex surrounding the fat globules in milk, has many healthful benefits for animals. Therefore, this study was conducted to explore the effect of MFGM supplementation on intestinal injury and inflammation in LBW mouse pups while being challenged with lipopolysaccharide (LPS). C57BL/6J LBW female neonatal mice were fed on breast milk and divided into four groups, including two normal diet groups (ND; CON group and LPS group) and the diet supplemented with two dosages of MFGM, namely, MFGM100 (ND plus MFGM at 100 mg/kg BW) and MFGM200 (ND plus MFGM at 200 mg/kg BW) from postnatal day (PND) 4 to PND 21. At PND21, pups from the LPS group, MFGM100 group, and MFGM200 group were injected intraperitoneally with LPS while the pups from the CON group were injected with equivalent volume of sterile saline. After 4 h of LPS administration, all pups were slaughtered and then the plasma, mid-ileum, and mid-colon tissue samples were collected. Our results showed that MFGM supplementation promoted the body weight from PND16 to PND21 and attenuated intestinal inflammation manifested by reduced histological damage, decreased secretion of TNF-α, IL-6, IFN-γ, and IL-1β, and improved oxidative stress characterized by increased SOD activity and decreased secretion of MDA. Expression of tight junction proteins (ZO-1, occludin, and claudin-1), MUC1, and MUC2 was increased in MFGM presupplemented groups compared to the LPS-challenged mice with normal diet. Meanwhile, the expression of proinflammatory cytokines and TLRs was decreased by MFGM presupplementation. Collectively, MFGM is a critical nutrient with an ability to improve the growth performance of LBW mouse pups, especially during the LPS challenge, by promoting the intestinal epithelial integrity and inhibiting inflammation through activating of TLR2 and TLR4 signals.
