Before refrigerators and freezers existed, fermentation is an age-old process that was used to preserve food.

These days of technology we don't need to ferment foods in order to preserve them, but they offer a myriad of health benefits which we know more about now because of numerous scientific studies.

Fermented foods are known to be popular for their gut-healing benefits for good reason. Research says that they can introduce good bacteria to the digestive system, which helps the immune system function way better, keeps digestive health in great shape, and provides a lot of nutrients.

Our gut is also known as our second brain due to the size, complexity and same characteristics in terms of neurotransmitters with our brain. As a matter of fact, "good bacteria" can stimulate cells in the lining of the intestine to produce the happy hormone or also known as the good neurotransmitter serotonin.

As part of a study published by the National Institutes of Health, Fermented foods were discovered to have a host of incredibly healthy activity including anti-oxidant, anti-microbial, anti-fungal, anti-diabetic, anti-atherosclerotic, and anti-inflammatory activity, as part of a study published by the National Institutes of Health. Another research discovered that gut microbiota, which is bolstered by the bacteria and probiotics in fermented foods, has the amazing capacity to control and decrease or eliminate inflammation and oxidative stress.

Researchers have found that there are a number of bacteria may help our bodies maintain calories and others may help us get rid of calories. Restoring our digestive flora is crucial when you have difficulties in losing weight.

It's a great idea to have a go-to menu of healthy fermented foods to keep you on a healthy track.
