Abstract:
The milk fat globule membrane (MFGM), the component that surrounds fat globules in milk, and its constituents have gained significant attention for their gut function, immune-boosting properties, and cognitive-development roles. The MFGM can directly interact with probiotic bacteria, such as bifidobacteria and lactic acid bacteria (LAB), through interactions with bacterial surface proteins. With these interactions in mind, increasing evidence supports a synergistic effect between MFGM and probiotics to benefit human health at all ages. This important synergy affects the survival and adhesion of probiotic bacteria through gastrointestinal transit, mucosal immunity, and neurocognitive behavior in developing infants. In this review, we highlight the current understanding of the co-supplementation of MFGM and probiotics with a specific emphasis on their interactions and colocalization in dairy foods, supporting in vivo and clinical evidence, and current and future potential applications.
Insights
Milk fat globule membrane (MFGM) and probiotics show synergistic health benefits. Their interaction enhances gut function, immunity, and cognitive development, particularly in infants.
Area of Science:
- Nutritional Science
- Microbiology
- Immunology
Background:
- Milk fat globule membrane (MFGM) is recognized for its health benefits, including gut function, immune support, and cognitive development.
- MFGM constituents can interact with probiotic bacteria like bifidobacteria and lactic acid bacteria (LAB) via bacterial surface proteins.
Purpose of the Study:
- To review the synergistic effects of co-supplementing MFGM and probiotics.
- To emphasize their interactions, colocalization in dairy foods, and supporting evidence.
Main Methods:
- Literature review of in vivo and clinical studies.
- Analysis of MFGM-probiotic interactions and their presence in dairy products.
Main Results:
- Evidence supports a synergistic effect between MFGM and probiotics for human health across all age groups.
- This synergy enhances probiotic survival and adhesion during gastrointestinal transit.
- The combination positively impacts mucosal immunity and neurocognitive behavior in infants.
Conclusions:
- Co-supplementation of MFGM and probiotics offers significant health advantages.
- Further research into their interactions and applications is warranted.
