Difference Between Yogurt and Kefir (With Table)

You may have come across kefir when browsing the dairy section of your local supermarket. Due to its similarity, it appears to be thinner, like liquid yogurt on the surface. Both are high in probiotics, which are good for our tummies and digestive systems. In some cases, such as fruit smoothies or granola, kefir and yogurt can be used interchangeably. Although yogurt is more popular in the United States, there are a few crucial differences to consider when deciding between kefir and yogurt.

Yogurt vs Kefir

The difference between yogurt and kefir is that both of them might possess the same kind of sour and acidic taste, but these two fermented products, but still kefir is a healthier item when compared with yogurt. Though yogurt has many healthy competent, still kefir is more potent. These two similar-to-eat dairy products are not the same.

Yogurt is a dairy-based product that is actually processed from the fermentation of milk by Yogurt is basically a dairy-based product that is actually processed by the fermentation of milk with the help of bacteria. Yogurt cultures are the bacteria that are used to manufacture yogurt. These bacteria make lactic acid by fermenting carbohydrates in milk, which reacts with milk protein to give yogurt its texture and acidic flavor. The most frequent milk used to produce yogurt is cow’s milk.

Kefir is a type of fermented milk-based drink that is created, sourced from grains of kefir, which in fact is a form of mesophilic symbiotic culture, that tastes like thin yogurt or ayran. The drink is made by inoculating cow, goat, or sheep milk with kefir grains and spreading it across Europe and the United States. It originated in the North Caucasus, specifically the Elbrus environs along the upper mountainous regions of Karachay and Balkaria, from where it spread to Russia, and from there it spread to Europe and the United States.

What is Yogurt?

Commercial producers make yogurt by boiling a yogurt mix, then cooling it and adding the beneficial bacteria. Streptococcus thermophilus and Lactobacillus bulgaricus are both required as starter cultures in current yogurt production techniques and standards.
Because of the symbiotic interaction between the two species, this is the finest beginning culture in the production of yogurt.

Lactose intolerant people and others who want to avoid dairy should consider soy, coconut, or oat-based replacement. Lactose intolerance is common in some people, however fermented dairy products like yogurt can be consumed safely. This is because the lactose concentration is reduced throughout the fermentation process.

Using starter cultures, one can create their own yogurt at home.
On the internet, there are numerous sources and vendors to choose from. Once the milk or other liquid has been fermented, the grains are strained out. They can then repurpose them to begin the next batch.

This can be a cost-effective approach to keep a supply of kefir on hand. Yogurt can be eaten or drunk as is. They can also use the ingredients in smoothies or cereals. It is critical not to cook yogurt because this will kill the beneficial bacteria. Fermented dairy products should always be kept in the refrigerator and should not be used after the expiration date on the box.

What is Kefir?

Kefir grains and cow’s milk have been used to make kefir since ancient times. We can also use goat or sheep milk to create it. The grains of kefir look like little cauliflower florets. The grains are added to the milk to ferment it, and then they are removed.

Kefir is the final product. In the next batch, the grains can be reused. They can also ferment the grains with water or coconut water and sugar to make dairy-free kefir. Kefir, on the other hand, includes a broader range of bacteria as well as helpful yeasts.

Saccharomyces cerevisiae and Saccharomyces unisporus are two of the most prevalent beneficial yeasts found in kefir. According to studies, Kefir, a reliable source of dairy nutrition, has the potential to possess antimicrobial as well as antifungal properties within the body, helps in strengthening the immune system of our body, has anti-allergic as well as anti-tumor properties, and also are highly beneficial for lactose malabsorption.

The variety in microbes, on the other hand, makes it impossible to compare the health consequences of various products.
Probiotics and yeasts are also found in kefir.

Probiotics, according to research trusted sources help to treat or prevent:

  1. Constipation
  2. Infection of the respiratory tract
  3. colitis ulcerative
  4. several diarrhea-causing illnesses, such as Clostridium difficile
  5. Taking excessive Antibiotics leading to diarrhea.
  6. the nose becomes inflamed and leads to a condition known as allergic rhinitis
  7. necrotizing enterocolitis is a dangerous illness that affects babies.
  8. Infections with Helicobacter pylori

Probiotics must be able to survive in the gut’s acidic environment. According to the authors of a 2017 review, Bifidobacterium strains found in fermented foods like kefir and yogurt should be acid-resistant.

Main Differences Between Yogurt and Kefir

  1.  Yogurts generally help us to keep our colons and intestines clean and healthy, whereas Kefir helps us to grow more friendly bacteria and yeasts in our bodies.
  2.   Like yogurt cannot help us in growing new bacteria or yeast, it cannot also help us in getting rid of the unfriendly ones, whereas Kefir can get rid of unfriendly or dangerous yeasts from the body.
  3.   Yogurt is harder to digest, whereas Kefir is easier to digest.
  4.  Yogurt acts as a food production unit for the yeasts and bacteria, Kefir does not have these abilities.
  5. Streptococcus thermophilus and Lactobacillus bulgaricus are two bacteria found in yogurt whereas Saccharomyces cerevisiae and Saccharomyces unisporus are two of the most prevalent beneficial yeasts found in kefir.

Conclusion

Kefir and yogurt are both nutritious foods to include in one’s diet. Because it contains a greater range of bacteria and yeasts than yogurt, kefir may have additional health advantages. People can buy convenient items in supermarkets or make their own kefir or yogurt at home, which can be more fulfilling and cost-effective.

Yogurt and other cultured dairy foods have progressed over time from simple operations to more precise procedures. Companies can produce new products to help people’s health thanks to advances in scientific understanding of microorganisms and the human microbiome.

To reduce the danger of negative effects, people who are new to fermented foods should take it slowly at first. People who have a medical problem or are using immune-modulating medicine should first consult a doctor.
