New Research on Dietary Combinations for Immune Benefits
Some simple combinations in our diets might actually provide greater immune benefits than just omega-3 supplements alone, according to a study from the University of Nottingham.
The researchers discovered that using kefir along with a mix of prebiotic fibers lowered inflammatory markers more effectively than omega-3 supplements or fiber by itself. The results, which appear in the Journal of Translational Medicine, highlight the potential role of gut bacteria in supporting both immune and metabolic functions.
Kefir is a fermented milk product that resembles yogurt and contains live bacteria and yeast.
When researchers combined kefir with prebiotic fiber, they noticed stronger outcomes. Prebiotic fiber helps foster healthy gut bacteria, enabling them to thrive and function better. When these beneficial bacteria multiply, they generate natural compounds that help lessen inflammation in the body.
In a six-week study, participants consuming a combo of kefir and fiber exhibited the most significant reduction in markers connected to systemic inflammation. Those taking only omega-3s and fiber saw improvements too, but not to the same degree.
The study’s lead scientist, Amrita Vijay, remarked that while all three dietary strategies led to reduced inflammation, the strongest effects were observed when fermented kefir was paired with a diverse prebiotic fiber mix.
In their analysis, researchers tracked systemic inflammatory markers, which indicate inflammation throughout the body. While inflammation can be a normal immune reaction, persistent low-level inflammation is associated with health issues like heart disease and metabolic disorders.
The study suggests that blending probiotics with prebiotics could offer broader support than focusing on a singular supplement. Dr. Vijay noted that the interactions between gut bacteria and dietary fiber might be crucial for maintaining immune balance and metabolic health.
Looking ahead, the research team aims to further explore how these synbiotic combinations might benefit individuals battling chronic inflammatory conditions.
