Background:

• Fermented dairy products (yogurt, cheese, kefir) are vital for nutrition, offering unique flavors and health benefits.
• Functional microorganisms, especially probiotics, enhance the biofunctional properties of dairy matrices.
• These products provide substantial nutritional and therapeutic advantages.

Purpose of the Study:

• To review the impact of microbial strains on the biofunctional properties of fermented dairy products.
• To explore their role in gut health, cardiovascular health, cancer risk, bone density, weight management, and diabetes control.
• To emphasize the importance of lactic acid bacteria in fermentation for safety and quality.

Main Methods:

• Literature review focusing on microbial impacts on fermented dairy biofunctionality.
• Analysis of studies investigating health outcomes related to consumption.
• Examination of fermentation processes and microbial strain selection.

Main Results:

• Fermented dairy products exhibit antimicrobial, hypocholesterolemic, and antioxidant effects.
• Microbial strains significantly influence gut and cardiovascular health, and disease risk reduction.
• These products enhance nutrient bioavailability and overall health outcomes.

Conclusions:

• Fermented dairy products possess significant biofunctional properties beneficial for human health.
• Optimizing fermentation methods and microbial strains is crucial for maximizing therapeutic potential.
• Further research is essential to fully understand and leverage the health benefits of these products.
