Fermentation is a process that uses yeast and bacteria to convert carbohydrates in food into alcohol or organic acids. It is used to prolong cheese, pickles, sour cream, yogurt, wine, and beer. While fermentation was once essential for humans’ ability to harness the nutritional benefits of certain foods, today, it is more common as a preservative than a necessity. Fermented foods rich in enzymes and probiotics can significantly improve digestion by helping your gut maintain its balance of good vs. bad bacteria.
What Makes Food Fermentable?
Certain types of food are fermentable while others are not. High-carbohydrate foods with low water content do not ferment well because they lack the moisture needed for the yeast and bacteria to thrive. These include grains, legumes, starchy vegetables, and fruits. On the other hand, foods high in sugar and have a high water content (such as cucumbers or grapes) are very fermentable.
How Is Food Fermented?
The process of fermentation begins when yeast and bacteria are added to food. The yeast ferments the sugar into alcohol, while the bacteria ferment it into organic acids. The type of yeast and bacteria used will determine the flavor profile of the fermented food. For example, lactic acid bacteria are often used to make sourdough bread and sauerkraut while Brettanomyces bruxellensis is used to make lambics. The time food is left to ferment also determines the flavor profile and nutritional value. A shorter fermentation period creates a milder tasting product, while a prolonged period creates more intense flavors. If you are trying to avoid specific yeasts or bacteria, check the label on your jar of fermented food to determine how long it has been sitting out for fermentation.
Foods that ferment best at room temperature include sauerkraut, sourdough bread, pickles, and kombucha. Milk kefir is an exception because it needs both warmth (around 75°F or 24°C) and refrigeration to ferment correctly. There are four different stages in milk kefir’s fermentation process, producing other enzymes and bacteria.
What Is Fermentation’s Role in Nutrition?
The fermentation of food is integral to our bodily health. Beneficial gut bacteria aid in the breakdown of complex carbohydrates into usable nutrients. This is why fermented foods are great for maintaining a healthy digestive system. Furthermore, some research suggests that increasing your intake of probiotics can increase energy levels and prevent disease-causing inflammation within the body.
Proponents of live-culture fermented foods believe they help improve nutrient absorption, regularity, and immune function. They also claim that beneficial yeasts like Saccharomyces boulardii can help reduce symptoms associated with irritable bowel syndrome. However, more research is needed to support these claims.
Are Fermented Foods Safe?
Yes, fermented foods are generally safe to eat. However, if you have a weakened immune system or are taking antibiotics, it is best to speak with a healthcare professional before eating them. People lactose intolerant may also have trouble digesting fermented dairy products like yogurt and kefir. If you experience any adverse symptoms after eating fermented foods, such as nausea, diarrhea, or vomiting, discontinue use and see your doctor.
If you’re new to fermentation, start incorporating small amounts of sauerkraut, sourdough bread, or pickles into your diet. As your body gets used to them, you can experiment with other fermented foods like yogurt, kefir, and kombucha. With a bit of trial and error, you’re sure to find a few favorites!
So, what is food fermentation?
Fermentation breaks down carbohydrates into alcohol or organic acids using yeast and bacteria. This process is beneficial for our digestive health and can provide us with additional nutrients. Fermented foods are generally safe to eat, but it is best to speak with a healthcare professional before starting if you have a weakened immune system or are taking antibiotics. Start by incorporating small amounts of sauerkraut, sourdough bread, or pickles into your diet, and as your body gets used to them, experiment with other fermented foods like yogurt, kefir, and kombucha.
