Probiotics are live bacteria that are beneficial for the health of your digestive system. While bacteria is typically associated with something that causes disease, it is important to know that bacteria can be both good as well as bad.
This good bacteria helps keep your gut healthy as well as boost the immune system and is classified as probiotics.
The reason why probiotics should be added into the diet is because people tend to consume a lot of sugary foods and alcohol or they may be taking antibiotics and other medications that can easily disrupt the balance between good and bad bacteria in the digestive tract. Moreover, poor eating habits can promote the growth of harmful bacteria faster than that of the good bacteria causing a lack of equilibrium in the gut.
This imbalance can be corrected by probiotics. Plus, these beneficial bacteria can also boost your immune system, reduce the chance of allergies, and help with the proper absorption of vitamins and minerals by the body. For some people it may also reduce serious symptoms of IBS.
Probiotics are naturally found in the human body and can also be supplemented through foods like yogurt, kefir, kimchi, tempeh, soft aged cheeses and sauerkraut. Basically these and other such foods are fermented and the good bacteria are added through the process of fermentation. The most common probiotic bacteria added to foods include lactobacilli and Bifidobacterium.
For most people, and anyone on the plant based diet, it is fairly easy to incorporate these probiotic fortified foods into their meals. These foods are considered safe for most people to eat and fit into a healthy diet.
