Overcome Your Gut + Digestive Issues With Ancestral Nutrition

Fermenting is a very old process of preserving food that our ancestors have been using for thousands of years. Some evidence suggests that people were fermenting foods as long as 8000-9000 years ago if not longer. “During the process of fermentation, microorganisms such as bacteria, yeast or fungi convert organic compounds – such as sugars and starch – into alcohol or acids. For example, starches and sugars in vegetables and fruits are converted to lactic acid and this lactic acid acts as a natural preservative” (5). Before Refrigeration, this was an extremely helpful method of preserving foods.
However, preservation is not the only benefit of fermentation. Fermentation offers many health benefits such as increase gut health, increased digestive health, increased bioavailability of nutrients, and increased immunity.
Trillions of bacteria, viruses, and fungi live in your gut (about 2-5 lbs worth). These make up your gut microbiome. While some bacteria, viruses, and fungi (or as they are collectively known: microbes) are associated with disease; others are important for the health of your gut, digestive system, immune system, weight management, and more (6).
A healthy microbiome is full of a diverse range of mostly beneficial bacteria. To increase the health of your microbiome you can:
Fermentation occurs when microbes convert organic compounds into alcohol or acids. In the case of veggies, starches and sugars are converted into lactic acid (5). The microbes responsible for this conversion hang around and are consumed along with the veggies. When consumed, these microbes are added to your gut microbiome, strengthening it.
Without a healthy microbiome, one can experience weight gain, gas, bloating, constipation, diarrhea, heartburn, trouble sleeping, eczema, inflammation, food intolerances, and increased infections (3, 4). Therefore it is critical to maintain a healthy gut in order to optimize your health.

By increasing the health of your gut, fermented foods improve your digestion. A healthy gut means more beneficial bacteria capable of effectively breaking down/digesting food. As well as more regular eliminations and an unhindered digestive system.
Fermenting also has a more direct impact on digestion by predigesting food. When microbes convert organic compounds into alcohol or acids, they are breaking down the food into smaller easier to digest parts. “For example, fermentation breaks down the lactose in milk to simpler sugars – glucose and galactose – which, if you are lactose intolerant, can make products such as yogurt and cheese potentially easier to digest” (5).

Better digestion means greater nutrient absorption since a greater percentage of the food is broken down into small enough particles to be absorbed into the blood stream. However this is not the only way fermenting increases nutrient absorption.
Fermenting decreases antinutrients in foods. Antinutrients are compounds present in plants that inhibit the absorption of nutrients by binding to vitamins and minerals making them too bulky to be absorbed into the blood stream. Antinutrients are often broken down during fermentation, rendering them useless. Therefore less nutrient absorption is being inhibited (2).
“Fermentation can also increase the availability of vitamins and minerals for our bodies to absorb. Additionally, by boosting the beneficial bacteria in your gut, you are promoting their ability to manufacture B vitamins and synthesise vitamin K” (5).
“Our immune system has co-evolved along with a diverse gut flora, not only to create defenses against pathogens, but also to develop tolerance for beneficial microbes. As a consequence, the immune system and the gut microbiota developed a mutualistic relationship, regulating one another and cooperating to support each other” (1). The interconnectedness of this relationship is shown by the fact that 70–80% of the body’s immune cells are found in the gut (1).
A healthy gut microbiome promotes a strong mucosa (gut lining) which acts as a barrier against pathogens and harmful bacteria. “A lack of beneficial bacteria allows disease causing microbes to grow causing inflammation in the gut wall. If you have recently taken a course of antibiotics, probiotic foods are particularly helpful (5)“.
It also allows for better communication between the gut and immune cells and better regulation of which molecules can and can’t enter the body.

My favorite way to eat fermented veggies is with salami, prosciutto, dry coppa, cheese, olives, and bone broth in my favorite lunch (recipe here).
Anyways, let’s get to some fermenting!
