- Prebiotics are a group of nutrients that are degraded by gut microbiota.
- Prebiotics are non-digestible substances, found in fiber. They serve as food for probiotic bacteria and stimulate their growth in the large intestine.
- They pass through the small intestine only partially digested, and so once they reach the colon, they are able to be fermented by the bacteria there.
- Hence option (a) is the correct answer.

Introduction:
Prebiotics are food ingredients that promote the growth and activity of beneficial gut bacteria. They serve as a source of nutrition for these bacteria and help them thrive in the digestive system. Prebiotics are different from probiotics, which are live bacteria that are beneficial for health when consumed.
Explanation:
1. Definition:
Prebiotics refer to non-digestible food components that stimulate the growth and activity of beneficial bacteria in the gut. They act as a food source for these bacteria, allowing them to flourish and provide various health benefits to the host.
2. Encouraging growth of beneficial gut bacteria:
Prebiotics specifically target the growth of beneficial gut bacteria, such as Bifidobacteria and Lactobacilli. These bacteria play a crucial role in maintaining a healthy gut microbiota, which is essential for overall well-being.
3. Food ingredients:
Prebiotics are naturally present in various foods, including fruits, vegetables, whole grains, and legumes. Some common examples of prebiotic-rich foods include onions, garlic, bananas, asparagus, and chicory root. These foods contain specific types of dietary fibers, such as inulin and fructooligosaccharides, which act as prebiotics.
4. Health benefits:
By promoting the growth of beneficial gut bacteria, prebiotics offer several health benefits. They help enhance digestion, improve nutrient absorption, and support immune function. Prebiotics also contribute to the production of short-chain fatty acids, which provide energy to the cells in the colon and have anti-inflammatory effects.
5. Differences from probiotics:
Although prebiotics and probiotics are often mentioned together, they are distinct entities. Probiotics are live bacteria that are ingested either through certain foods or as supplements. They directly introduce beneficial bacteria into the gut. Prebiotics, on the other hand, are food ingredients that stimulate the growth of existing beneficial bacteria in the gut.
Conclusion:
In conclusion, prebiotics are food ingredients that encourage the growth of beneficial gut bacteria. They are not antimicrobial drugs, preservatives, or vaccines. Prebiotics play a crucial role in maintaining a healthy gut microbiota and offer several health benefits. Including prebiotic-rich foods in the diet can contribute to overall well-being and digestive health.
