The study found improvements in some cholesterol measurements among participants consuming additional dairy products.

However, the improvements observed in the kefir group were similar to those in the milk group.

Another study involving men with elevated cholesterol found that consuming approximately 500 milliliters of kefir daily for four weeks did not produce significant changes in cholesterol levels.

These differences highlight why kefir should not be promoted as a guaranteed cholesterol-lowering food.

If you want to improve your cholesterol profile, consider prioritizing foods with stronger evidence of cardiovascular benefits, including oats, beans, lentils, nuts, seeds, and foods rich in unsaturated fats.

Plain kefir can complement these foods as part of an overall healthy eating pattern.

10. Kefir Provides Nutrients That Support Strong Bones

Healthy bones require several nutrients, including calcium, phosphorus, vitamin D, protein, and magnesium.

Calcium is particularly important because it is the primary mineral responsible for maintaining bone structure and strength.

Kefir made from dairy milk is a useful source of calcium and phosphorus.

According to USDA food composition data, one cup of low-fat kefir provides approximately 316 milligrams of calcium.

This represents a meaningful contribution toward daily calcium requirements.

Kefir also provides protein, which supports the maintenance of bone and muscle tissue.

Some researchers have investigated whether the microorganisms in fermented dairy products can influence calcium absorption and bone metabolism.

Animal studies have suggested that kefir and kefiran may affect bone-related processes, including the activity of cells involved in bone formation and breakdown.

There have also been small human studies investigating kefir consumption alongside calcium supplementation in people with osteoporosis.

One study reported improvements in certain bone mineral density measurements among participants receiving kefir alongside calcium.

Another study involving postmenopausal women examined possible changes in bone resorption markers following kefir consumption.

These findings are interesting, but they are not sufficient to establish kefir as a treatment or prevention method for osteoporosis.

The strongest established nutritional benefit is that dairy kefir supplies calcium and protein, both of which are important for maintaining normal bone health.

Vitamin D is also essential because it helps the body absorb calcium.

Not all kefir products contain significant amounts of vitamin D, so check the nutritional label rather than assuming that every product provides the same amount.

For stronger bones, combine adequate calcium and vitamin D intake with weight-bearing exercise, resistance training, and other healthy lifestyle habits.

11. Kefir May Support Healthy Weight Management

Maintaining a healthy body weight involves balancing energy intake with energy expenditure.

Although no single food can independently cause significant or lasting weight loss, certain foods can make a balanced eating plan easier to follow.

Kefir may be useful in this respect because it contains protein and can provide a satisfying alternative to sugary beverages or highly processed snacks.

Protein helps support muscle maintenance and contributes to feelings of fullness after meals.

A cup of plain low-fat kefir contains approximately 9 grams of protein, making it a convenient addition to breakfast or an afternoon snack.

Researchers have also investigated whether kefir's microorganisms influence metabolic processes related to body fat.

Some animal experiments suggest that certain kefir-derived compounds may affect fat accumulation and lipid metabolism.

However, these findings have not been consistently confirmed in humans.

A randomized controlled trial involving overweight or obese premenopausal women compared kefir consumption with milk and a control diet over eight weeks.

The participants consuming additional dairy products experienced improvements in body weight and waist measurements compared with the control group.

Importantly, kefir did not produce significantly greater weight loss than milk.

This suggests that the benefits may have been related to the overall dietary intervention and additional dairy consumption rather than a unique fat-burning effect of kefir.

If you are trying to lose weight, plain kefir can still be a practical choice.

For example, you can use it to prepare a filling smoothie with:

• Half a banana.

• A handful of strawberries.

• One cup of plain kefir.

• One tablespoon of chia seeds.

• A small amount of cinnamon.

Avoid adding large amounts of honey, sweetened syrups, or fruit juice if you are trying to control your calorie intake.

The most important factor remains your overall eating pattern and long-term consistency.

12. Kefir-Derived Compounds May Support Wound Healing

Another interesting area of kefir research involves its possible role in wound healing.

Wound healing is a complex process involving several stages, including blood clot formation, inflammation, tissue regeneration, and remodeling.

During this process, the body works to repair damaged tissues while preventing infection.

Certain kefir microorganisms produce antimicrobial substances that may inhibit the growth of some harmful bacteria.

Researchers have therefore investigated whether kefir-derived compounds could be incorporated into topical products designed to support wound care.

One experimental study investigated a gel prepared from cultured kefir grains and applied it to infected wounds in animals.

The researchers observed differences in wound healing, inflammatory responses, and scar tissue formation between the treatment groups.

Other laboratory studies have examined the antimicrobial properties of kefir extracts against selected microorganisms.

However, these findings are preliminary.

There is currently insufficient clinical evidence to recommend ordinary kefir as a topical wound treatment.

Drinking kefir should also not be expected to accelerate wound healing in a predictable or medically significant way.

For ordinary cuts and scrapes, follow established wound-care recommendations, including cleaning the wound, protecting it with an appropriate dressing, and seeking medical attention when necessary.

13. Kefir May Influence Allergic and Inflammatory Responses

Allergic reactions occur when the immune system responds excessively to substances that are normally harmless, such as pollen, dust mites, or certain foods.

In people with allergic conditions, immune responses can contribute to symptoms affecting the skin, respiratory tract, and digestive system.

Because the gut microbiome interacts with immune regulation, researchers have investigated whether probiotics could influence allergic responses.

Kefir contains microorganisms that may affect immune signaling and inflammatory processes.

Some animal studies have suggested that kefir consumption may reduce allergic airway inflammation and influence immune responses associated with asthma.

Research published in Immunobiology has explored the potential immunomodulatory effects of kefir in experimental models of allergic respiratory disease.

The findings suggest that certain kefir-derived microorganisms may influence immune pathways involved in allergic reactions.

However, these studies do not demonstrate that drinking kefir treats asthma, hay fever, or other allergic conditions in humans.

People with asthma should continue following their prescribed treatment plans, including using inhalers and other medications as directed.

There is also an important distinction between dairy intolerance and dairy allergy.

Kefir may be easier to digest for some people with lactose intolerance, but it is not automatically safe for someone with an allergy to milk proteins.

If you have a diagnosed food allergy, consult an appropriate healthcare professional before introducing dairy-based fermented products.

14. Kefir Contains Bioactive Compounds Being Investigated for Potential Anticancer Effects

One of the most fascinating areas of kefir research concerns its potential anticancer properties.
