Health Benefits of Kefir
1. Improves Gut Health
Kefir is a rich source of probiotics, which help maintain the gut microbiome. Probiotics are healthy bacteria found in certain foods that aid in digestion. Our gut has a specific bacteria microbiome that keeps it healthy. However, certain processed foods and lifestyle habits can disrupt this microbiome and cause bloating, indigestion, acid reflux and flatulence. Therefore, it is essential to reintroduce healthy bacteria into the gut. You can easily do that by using probiotics.
The probiotics found in kefir can remove mutagens and carcinogens from our bodies. Therefore, it can reduce the risk of getting cancers and other illnesses.
2. Improves Heart Health
One of the leading causes of heart health issues is lifestyle disorders. Health problems like atherosclerosis, high cholesterol, hypertension, etc., may damage heart health. The main reason behind these disorders are the high levels of unhealthy fats, called saturated fats, in our body.
Studies suggest that kefir may lower cholesterol and serum triacylglycerol in the blood. These are unhealthy fats that may accumulate in the arteries and cause blockages. In addition, the probiotic microorganisms in kefir can enhance fat metabolism in the body. They help form bile acids, which digest and metabolise fats. By reducing unhealthy fats in the body, the risk of acquiring lifestyle-related heart problems reduces.
Kefir can also reduce blood pressure or hypertension. The fermented products of the probiotics in kefir can help control blood pressure. For example, kefir reduces the formation of the hormone aldosterone, which increases blood pressure.
3. Improves Liver Health
Kefir can improve your liver health by reducing fatty liver syndrome. Fatty liver syndrome happens when there is an increase in fat accumulation in and around the liver.
A study suggests that kefir can reduce fat deposition around the liver. It can also lower cholesterol and triglyceride deposition in the liver by improving lipid metabolism in the body. As a result, it reduces the content of excessive fat deposition throughout the body. It also helps keep organs healthy.
4. Improves Kidney Health
Kefir can reduce the amount of uric acid and creatinine in the body. The probiotic population in kefir can consume and degrade toxic waste like uric acid and creatinine. As a result, this can be beneficial for reducing the kidney’s load.
5. Improves Bone Health
Kefir is an excellent source of calcium and vitamin K2, both required for healthy bones. Calcium is essentially responsible for our bone health. The lower the calcium levels in our body, the weaker our bones get. Vitamin K2, on the other hand, helps in absorbing calcium into our bones. Therefore, we need to have a regular calcium intake and vitamin K2 to maintain our bone health. 100 g of kefir provides 120 mg of calcium, 20% of the recommended daily intake value.
Regular calcium and vitamin K2 intake can reduce the chances and slow down bone diseases.
Osteoporosis, a bone disease affecting the elderly, causes pores or cavities in bones. As a result, this can make them very weak and easy to break. Also, kefir may aid in preventing fractures and improving overall bone health.
6. Improves Skin Health
Kefir can promote healthier skin and reduce blemishes. It can also improve skin abnormalities like scars, burns, and even eczema. The cell membranes, bacterial metabolites and dead bacteria derived from the probiotics play a role in improving skin health. In addition, these compounds help in strengthening the skin barrier and preventing the growth of other microorganisms.
For example, hyaluronic acid found in probiotics helps in wound healing. In this case, it may help heal scars on the skin. As a result, many cosmetic products have started incorporating hyaluronic acid to promote skin healing.
7. Antibacterial Properties
Kefir shows anti-bacterial properties against several harmful microorganisms. A study demonstrates the antibiotic potential of kefir against various types of bacteria and yeast. Kefirs antimicrobial effects were comparable to common antibiotics like ampicillin. Therefore, kefir kills harmful bacteria, helicobacter pylori, salmonella typhi, escherichia coli, streptococcus aureus.
Additionally, there are certain compounds called bacteriocins present in kefir which can also stop the growth of harmful bacteria. Bacteriocin is a type of protein that can attack particular bacterial cell walls and kill them.
8. Anti-cancerous Properties
A study demonstrates the effectiveness of kefir against a specific type of cancer in mice. Additionally, the study showcases an immunity boost after the consumption of kefir. Furthermore, other studies have shown a reduction in breast cancer due to kefir consumption by 56%. Therefore, kefir shows promising results of kefir against cancer.
Furthermore, in kefir, bioactive compounds, like proteins and polysaccharides, can directly act on cancer cells. They can disrupt the cell cycle and the growth of cancer cells. By doing so, they activate apoptosis, or the cell-death mechanism, in cancer cells.
Kefir helps provide anti-inflammatory effects in the body. Specific bioactive compounds present in kefir can reduce the inflammatory cells. Eosinophils are inflammatory cells that cause inflammation and other allergic responses against foreign microorganisms. Therefore, kefir may be a potential treatment for allergic bronchial asthma.
A study suggests that the wound-healing properties of kefir are due to the probiotics. Also, wound healing is due to kefir’s anti-inflammatory effects. Inflammation is the body’s defence mechanism against bacteria and other microbes. However, prolonged inflammation can be dangerous to the body and cause several health issues. For instance, it can lead to diabetes, obesity, cancer, and other chronic illnesses.
