The digestive process has two distinct jobs: one is to break down the food we eat, second is the absorption of the nutrients. Once this occurs, the nutrients are used to make new cells, which forms our tissues. Those tissues make organs, finally organ systems. This process is necessary for our body to perform optimally. If the break down is incomplete, the building up cannot proceed correctly. In essence, "we are what we eat", but more accurately, "we are what we digest."
To help with this process of digestion many cultures have found that eating fermented foods has many benefits. These fermented foods, such as kimchi, sauerkraut, yogurt, and sourdough bread, are enzyme rich and can aid in our digestive processes. They also contain living microorganisms (beneficial bacteria) that can aid in our colon health and immune health. Finally, fermented foods are also a good source of Vitamin B-12 and K2. Vitamin B-12 is an essential nutrient you can't get from plants and is known to aid in red blood cell formation, a regulator of the nervous system, helps to maintain heart health and aid in strong nails and healthy hair. The benefits of Vitamin K2 are known to help you maintain cardiovascular health, improve your skin, strengthen bones, and promote brain function.
It is also important to note that a little bit goes a long ways. Start with one bite during main meals and you will start reaping the benefits today! As time goes on you can increase your intake and who knows maybe even end up making your own.
