Probiotics
उत्तर
- Probiotics are milk products containing active bacteria like Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium bifidium, etc.
- These bacteria maintain the balance of intestinal micro-organisms by increasing the population of microbes that help in digestion and decreasing the population of harmful microbes such as Clostridium.
- They also improve resistance and lower the ill effects of harmful substances formed during metabolic activities.
- When we take antibiotics, the useful microbes in the alimentary canal become inactive. These microbes can be made active by consuming probiotics.
- Also, probiotics are used for the treatment of diarrhoea and treatment of poultry diseases.
