The correct answer is Option 3: Both 1 and 2.

1. Probiotic food contains live bacteria which are considered beneficial to humans:

This statement is correct. Probiotic foods, such as yogurt, kefir, sauerkraut, and kimchi, are specifically made or fermented to contain live bacteria strains that are beneficial for human health. These bacteria are known as probiotics and can include strains of Lactobacillus, Bifidobacterium, and other species. When consumed, these live bacteria can reach the gut and have various positive effects on the body.

Probiotics can aid digestion, support the immune system, and help maintain a healthy balance of gut microbiota. They can also inhibit the growth of harmful bacteria in the gut by competing for resources and producing antimicrobial substances. The live bacteria in probiotic foods are usually able to survive the digestive process and colonize the gut, providing ongoing benefits.

2. Probiotic food helps in maintaining gut flora:

This statement is also correct. Gut flora, also known as gut microbiota, refers to the diverse community of microorganisms that reside in our digestive system. These microorganisms play a crucial role in digestion, nutrient absorption, immune function, and overall health. Imbalances in gut flora have been associated with various health issues.

Consuming probiotic foods can help maintain a healthy balance of gut flora. The live bacteria in probiotics can populate the gut and interact with the existing microbiota, promoting diversity and beneficial interactions. They can also enhance the growth of other beneficial bacteria and discourage the overgrowth of harmful ones. By supporting a healthy gut flora, probiotic foods contribute to overall digestive health and general well-being.

In conclusion, both statements are correct. Probiotic foods contain live bacteria that are considered beneficial to humans, and they help in maintaining a healthy balance of gut flora.
