Why are fermented foods so healthy?

“Mom, what are germs?” my five-year-old daughter asked me recently. Well, how do you explain that to a child who is in group two. Here we go… “Bacteria are microorganisms that consist of only one cell. They are actually some kind of very small creatures”, I begin. “As small as an ant?” she asks. “No, much less. They are so small that you cannot see them. Some bacteria can make you sick, and others make you healthy and strong. It is therefore important to wash your hands well after going to the toilet. That way you could avoid get rid of the bad bacteria.” “But how do the healthy bacteria get to me?”, I answer very quickly. “For example, by eating yogurt or sauerkraut”, I explain. “Yaks, sauerkraut.” My daughter makes a dirty face. “But why sauerkraut?” And that’s how we get to talking about fermentation. What exactly is fermentation, why is it so healthy and can I also learn it myself through a fermentation course? Read with me!

What is fermentation?

Fermentation is a form of food preservation. In fermentation, bacteria, fungi and yeast are allowed to enter the food in a controlled and responsible manner. If you are a lot SEC would describe, you deliberately let the food go into a rotting process. Your first reaction may be: yuck. But if I explain to you what it does to food, I’m sure you can also name fermented foods that you love.

Examples of fermented foods

Fermentation gives food a longer shelf life. It is a technique that has been used for centuries to preserve food and make it more palatable. The technique is still commonly used today, even by the modern food industry. Examples of fermented products are yoghurt, soy sauce, cheese, olives, sourdough bread, salami, wine and sauerkraut. I bet there are at least three things here that you really like 😉

Why are fermented foods so healthy?

Fermented food is packed with good gut bacteria: probiotics. Without getting too technical, it can be said that probiotics are important for the health and balance of the microbiome. The health of your gut affects the health of your whole body. Much research is currently being done into why exactly this is so. Eating enough fibre, a varied diet and fermented foods contribute positively to your gut health.


So you can buy a lot of fermented food in the supermarket. Unfortunately, fermented here doesn’t always mean it’s a healthy choice either. Just think of things like alcohol and salami. It is therefore nice to start fermenting yourself. How cool to make your own kimchi, sauerkraut or soy sauce. Difficult? Oh no! You can also learn it by taking a fermentation course.

Where do you learn to ferment?

What do you learn on such a fermentation course? This of course depends on where you take the course. For example, on the online course at Leerfermenteren.nl you learn everything about ingredients, techniques, materials and recipes. You simply follow the process from your own kitchen at your own pace. It consists of more than 35 lessons in the form of videos. They are easy to follow and can be viewed without restrictions. You also receive the Fermentation handbook with the course.

Kimchi for my neighbor

Following such a course gives you a flying start. Of course, you can also get started yourself, but I wouldn’t do it so quickly with a view to food safety and the taste of the product. To each their own, of course! Anyway, I think it would be very cool to take the course. I have long dreamed of making my own kimchi. I now always get this from our Korean neighbor. I think it would be so nice to surprise her with my homemade kimchi. I wonder if I can get him as good as her.
