De voordelen van kefir: een gezondheidsdrank met vele deugden

The kefir is a traditional fermented drink that is increasingly gaining attention for its numerous health benefits. This ancient drink is known to improve digestion, strengthen the immune system, and balance the gut microbiota. But its virtues don't end there. Let's explore together why it has a place in your everyday diet.

What is Kefir?

Originating from the Caucasus, kefir is made from kefir grains, a symbiotic mixture of bacteria and yeast. There are two main types: milk kefir and water kefir (or fruit kefir).

• Milk kefir: Made from fermented milk, it resembles a liquid yogurt but is richer in probiotics. The kefir grains contain symbiotic microorganisms that convert lactose into lactic acid, making it a more digestible drink for those with lactose intolerance. 99% of the lactose present is indeed broken down.
• Water kefir: This variant is made by fermenting kefir grains in sugary water. After 24 to 48 hours of fermentation, a sparkling, tangy drink is produced, which is, of course, lactose-free.

Benefits of Kefir

1. Improved Digestion

Thanks to its richness in probiotics, kefir promotes healthy digestion and helps balance the gut microbiota. By strengthening the intestinal flora, it reduces digestive discomfort such as bloating, constipation, or diarrhea, and supports proper gut transit. Milk kefir can even contain up to 10 times more probiotics than regular yogurt, while a 250 ml glass of fruit kefir can contain up to 2.5 billion microorganisms.

2. Strengthening the Immune System

Kefir contains beneficial bacteria that stimulate immune system activity. It specifically enhances defense mechanisms such as the production of macrophages and the maturation of CD4+, CD8+, and B lymphocytes. It also helps reduce the expression of pro-inflammatory molecules (cytokines). Moreover, research shows that kefir might exhibit antiviral activity against various viruses (Zika, H1N1, hepatitis B and C, Herpes, etc.). Therefore, kefir may help mitigate excessive immune responses, such as the cytokine storm seen in some COVID-19 patients.

3. Low Sugar Content

The preparation of fruit kefir (or water kefir) involves a mixture of water, sugar, and fruit kefir grains. The grains contain microorganisms (yeasts and bacteria) that ferment the sugary water, transforming it into a sparkling, mildly tangy drink.

In 48 hours, approximately 66 to 80% of the sugar is consumed by the yeasts and bacteria, which significantly reduces the sugar content. It then becomes a far less sugary effervescent drink compared to the initial liquid, making kefir an ideal alternative to sodas.

4. Anti-Inflammatory Properties

The kefir is unpasteurized and contains live probiotics and digestive enzymes that help combat inflammation in the body. Additionally, water kefir, made from fruits, is rich in antioxidants. It's a real boost to our daily diet, enriching our intake of anti-inflammatory compounds.

Milk Kefir or Water Kefir?

While both types of kefir offer similar health benefits, they have different uses in cooking and unique compositions:

• Milk kefir is creamy and can be used as a base for sauces, pancakes, or cakes. It perfectly replaces milk in recipes or yogurt in desserts.
• Water kefir is lighter, sparkling, and refreshing. Ideal as a daily drink or as an ingredient in a mocktail, it’s a must-have for aperitifs and makes a perfect substitute for sodas.

Kefir vs. Kombucha, What’s the Difference?

Although kefir and kombucha are often compared, they have notable differences: kombucha is made from fermented sweet tea, while kefir comes from the fermentation of sugary water (for water kefir) or milk. Kombucha requires 7 to 14 days to ferment, whereas water kefir only takes 24 to 48 hours. Lastly, kefir contains a wider variety of beneficial bacteria, particularly lactobacilli, which are essential for gut health, and it is often less sweet than kombucha.
