Streptococcus thermophilus is a probiotic bacterium widely used as a starter culture in the production of fermented dairy products such as yogurt and cheese. This bacterium is known for its probiotic properties and has numerous health benefits.
Health Benefits
Digestive Health Support: Streptococcus thermophilus helps maintain a healthy gut microbiota, reducing symptoms of gastrointestinal disorders such as diarrhea, irritable bowel syndrome (IBS), and colitis. It produces lactic acid, which lowers the pH in the intestines, creating unfavorable conditions for pathogenic bacteria.
Immune System Support: This bacterium can enhance the immune response by increasing antibody production and stimulating the activity of natural killer (NK) cells. It also reduces pro-inflammatory cytokine levels, thereby decreasing inflammation and increasing resistance to infections. Studies have shown that Streptococcus thermophilus can reduce the risk of infections in older adults.
Lactose Tolerance Improvement: Streptococcus thermophilus can help individuals with lactose intolerance. This bacterium produces lactase, an enzyme that breaks down lactose, allowing better digestion of dairy products in people who typically have difficulty digesting lactose.
Skin Health Support: This bacterium can help reduce symptoms of skin conditions such as eczema and acne. It decreases skin inflammation and improves its barrier function. Streptococcus thermophilus produces bioactive peptides with antimicrobial properties, further aiding in maintaining skin health.
Antimicrobial Properties: Streptococcus thermophilus produces bacteriocins, antimicrobial peptides that inhibit the growth of pathogenic bacteria such as Escherichia coli and Listeria monocytogenes. These properties make this bacterium useful for extending the shelf life of fermented products and enhancing their safety.
Potential Side Effects
Streptococcus thermophilus is generally safe for use, but like other probiotics, some people may experience mild digestive issues such as bloating or gas. These side effects are usually temporary and subside after a few days of regular probiotic use.
