The Power Duo: Streptococcus Species in Milk Kefir
- Streptococcus thermophilus (St. thermophilus)
St. thermophilus is more than a microorganism in kefir; it's a health-boosting companion with the following benefits:
-
Digestive Health: This probiotic strain can help improve lactose digestion and reduce symptoms of lactose intolerance, making it particularly valuable for individuals with this condition1.
-
Bone Health: St. thermophilus has been found to improve the absorption of minerals, such as calcium and magnesium, which are vital for bone health2.
- Streptococcus paracitrovorus
St. paracitrovorus is lesser-known among kefir's bacterial constituents, and comprehensive research is still needed to understand its specific health benefits. Despite this, its consistent presence in kefir grains points towards a potential functional role in this probiotic community.
Table Summary
| Microorganism | Key Health Benefits |
|---|---|
| Streptococcus thermophilus | Improves lactose digestion, enhances mineral absorption |
| Streptococcus paracitrovorus | Assumed potential probiotic properties, more research is needed |
