For thousands of years, people have fermented foods to preserve them for when supplies of fresh foods were not available.
The Romans preserved cabbages with salt, and Genghis Khan fed his armies fermented cabbage to sustain them on their campaigns through Europe. This use of preserved, fermented foods was a common practice for travelers as a source of nutrients. As late as World War I, allied forces relied on fermented cabbage, or sauerkraut as we now know it, to supply nutrients to soldiers on the battlefields of Europe.
The process of fermentation helps to preserve the food for use many months later. Fermentation also generates many health benefits for the consumer. The essential nutrients and vitamins are preserved. Sugars are broken down so they are more easily absorbed with far less insulin or allergy reaction, in the case of lactose intolerance to dairy products. The process also generates enzymes that are essential to supporting the digestion of foods that we eat. Finally, they are natural probiotics, jam-packed with beneficial microorganisms.
A healthy gut, supported by a strong population of beneficial bacteria, serves as a powerful booster for your immune system. The digestive tract is where nutrients are extracted from food and absorbed by the body. Enzyme and microbial activity accelerates digestion and generates enzymes, vitamins and antioxidants that are essential to health. They also protect us from pathogens and flush out toxins from our bodies.
You can find a variety of ready-to-use fermented products at your local supermarket. They include yoghurt, which is fermented milk (usually cow’s milk). The fermentation process breaks down the milk lactose to make it easier to digest and the yoghurt supplies billions of helpful bacteria. Be careful of brands with large amounts of sugar added, as that will create other problems. Another healthy fermented product from milk is kefir, a drink often found in the supermarket refrigerator.
Kombucha tea is another good source of enzymes and beneficial microbes. Kombucha is made from fermenting black tea. Other products you may find in the supermarket include kimchi, a Korean version of fermented cabbage and a mixture of other vegetables. Raw apple cider vinegar is also loaded with beneficial bacteria and has many different uses apart from supporting a healthy digestive system. You may find Japanese products like miso, and natto, both loaded with microbes and used in cooking soups, marinades and sauces.
If you feel adventurous, the processes for making your own fermented yoghurt, kefir, pickles and kimchi are relatively easy and they require no special equipment. Select healthy organic ingredients and you will be able to rely on the process for creating your own healthy, nutritious probiotic foods.
