All About Active Bacteria and Live Cultures

What are Live and Active Bacteria?

When one hears the word “bacteria” the first thing that comes to mind is the little critters that cause infections and diseases.

Although partly true, this may not always be the case. With the presence of harmful bacteria also exist good active bacteria that naturally reside in our body and are essential to our survival. There are about 100 trillion good and bad bacteria that live in the digestive system alone. 

Good live and active bacteria are also referred to as probiotics. Probiotics are a combination of live and beneficial bacteria and yeast in the body. These bacteria help in ways such as fighting off harmful bacteria. 

Some examples of good bacteria and yeast that exist in the body include:

  • Lactobacillus
  • Bifidobacteria
  • Streptococcus thermophilus
  • Saccharomyces boulardii

The human body is dependent on these bacteria to help digest food, produce certain vitamins, and regulate the immune system.


Benefits of Active Cultures on Gut Health

The gastrointestinal system, also known as the gastrointestinal tract, digestive system, or gut, is a group of organs that starts from the mouth and to the small intestine, colon, and rectum. This system serves as the body’s primary site of taking in and absorbing nutrients. 

The significance of gut health extends from less susceptibility to sickness, immune system support, less inflammation, better emotional well-being, and brain health. The gut flora or gut microbiome encompasses trillions of bacteria, fungi, and viruses co-exist with our cells. 

Other types of good bacteria can also:

  • Keep harmful bacteria from making you sick
  • Help create vitamins
  • Support the cells in the gut to prevent bad bacteria (ingested through food or drinks) from entering the bloodstream
  • Breakdown and absorb medications.

Research in animals suggests that changes in the gut florasuch as inflammation of the gutcan also affect the brain and cause symptoms similar to Parkinson’s disease, autism, anxiety, and depression.

Alongside a healthy lifestyle, exercise, stress reduction, and avoidance of unnecessary antibiotics, a healthier diet could restore the balance in the gut flora.


Sources of Probiotics

Firstly, for a microbe to be considered as a probiotic, it must have several characteristics. These include being able to:

  • Be isolated from a human.
  • Be safely consumed.
  • Have a proven benefit to you.
  • Survive in the intestine after being eaten.

Fermented products have reputable health benefits on general health and brain functionality. 

Probiotics, also known as good bacteria, are present in fermented foods such as yogurt with live cultures and kifer. These active cultures found in fermented foods help increase the good bacteria in the digestive system. 

Here are some of the most common fermented foods that help increase probiotics:
