Kefir: The Probiotic Powerhouse That's Taking Over Indian Kitchens
Kefir's the cool cousin of Dahi—fermented, fizzy, gut-happy, and lactose-light. Desi-approved, Insta-worthy, and your stomach's new BFF.
Imagine a tangy, fizzy milk drink that's like yogurt's well-traveled cousin. Meet kefir (pronounced keh-fear)—a fermented drink that originated in the Caucasus and Tibet centuries ago. It's made using kefir 'grains"—small, cauliflower-like clusters of bacteria and yeast.
These grains are mixed with milk (cow, goat, or even plant-based). Leave it at room temperature for 12–24 hours, strain it, and you have kefir—ready to nourish your gut and your body.
These grains break down lactose (milk sugar) into lactic acid, a small amount of carbon dioxide (which gives it a slight fizz), and a trace amount of alcohol (about 0.002%, barely noticeable). The result? A probiotic-rich drink that supports digestion without the sugar rush.
What's Inside This Drink?
~4% protein, 1% fat, 7% carbs, 87% water (~52 calories per 100 ml).
Rich in B-vitamins, vitamin A, calcium, and a powerful probiotic mix that supports gut health.
Why Should You Care?
For Better Digestion
Kefir contains billions of probiotics per ml, including Lactobacillus kefiri, which help fight harmful gut bacteria and improve digestion.
Certain peptides in kefir may help lower blood pressure and cholesterol. Early studies in animals show promise, though large-scale human trials are still limited.
Helps Manage Blood Sugar
Some small studies suggest kefir can help improve fasting glucose and insulin levels in people with type 2 diabetes. It may also reduce inflammation, though results are mixed compared to plain milk.
Boosts Immunity
Kefir produces compounds such as bacteriocins that fight harmful bacteria such as E. coli. Its probiotics also enhance the immune system by increasing protective antibodies and immune cells.
Good for Brain Health & Mood
A healthy gut supports a healthy brain. Some studies, including one on Alzheimer's patients, showed memory improvement after consuming kefir.
Its antioxidant properties may also help reduce stress and improve mental clarity.
Cancer-Fighting Potential
Lab tests show kefir may have anti-cancer, anti-inflammatory, and antioxidant properties. It appears to inhibit colon cancer cells in Petri dishes, but conclusive human trials are still underway.
Stronger Bones, Better Skin
Loaded with calcium and vitamin D, kefir supports bone health. Its antioxidant-rich profile may also improve skin health, digestion, and overall wellness.
All these said, there is sufficient scientific research backing up the benefits of Kefir with respect to heart health and cancer aiding factors.
Emerging research suggests that kefir isn't just good for your gut—it might also be a powerful ally for your heart. A 2024 double-blind, randomized, placebo-controlled clinical trial involving 67 elderly participants.
It was found that probiotic-fortified kefir significantly improved certain atherogenic indices, which are markers linked to cardiovascular risk. This indicates that regular consumption of kefir could have a positive impact on heart health by improving lipid profiles and reducing cardiovascular risks. (Source: pubmed.ncbi.nlm.nih.gov, pmc.ncbi.nlm.nih.gov)
Backing this, a 2023 study published in Frontiers in Nutrition tested kefir peptides on mice that are genetically prone to developing cardiovascular disease. The mice, when fed a high-cholesterol diet supplemented with kefir peptides, showed a marked reduction in vascular calcification and atherosclerosis.
The peptides worked by reducing oxidative stress and systemic inflammation, both critical factors in heart disease development. (Source: frontiersin.org)
Adding to this evidence, another 2023 study demonstrated that kefir made using traditional microorganisms significantly lowered LDL (bad) cholesterol levels and improved plasma markers of inflammation in male participants.
This underscores kefir's role in managing cholesterol and enhancing overall cardiovascular health. (Source: cdnsciencepub.com)
Can Kefir Help in Cancer Prevention?
Science is increasingly exploring kefir's role beyond digestion, particularly its potential in fighting cancer. Studies show that kefir might contribute to the anti-tumor process across various cancers, including breast, leukemia, skin, gastric, colon cancers, and sarcomas.
The proposed mechanism? Kefir's ability to positively modulate the gut microbiome and strengthen immune responses, which plays a crucial role in cancer prevention. (Source: mdpi.com)
One noteworthy case study involving 1,699 women suggested that high consumption of dairy products—including kefir—was associated with a lower risk of breast cancer among premenopausal women.
Why Kefir Makes Sense for Indian Lifestyles
Urban stress is real. Studies suggest fermented foods like kefir can improve digestion, sleep, and mood.
It fits our food culture. Indians love dahi, lassi, and achar. Kefir is a natural extension of that tradition with even more probiotic power.
Low in lactose. With 70–80% of Indians lactose-sensitive, kefir is a gentler dairy option.
Affordable. Homemade kefir costs less than daily chai. Just buy the grains once and reuse them indefinitely.
Things to Know Before You Start
Research is still emerging. Much of the science is based on lab studies and small human trials.
Start slow. Some people may experience bloating or mild discomfort initially, especially if sensitive to histamine.
Check labels. Store-bought kefir can contain added sugars. Homemade kefir is healthier and more affordable.
Consult your doctor. If you're pregnant, have immune issues, or severe allergies, check before consuming raw or unpasteurized kefir.
How to Add Kefir to Your Routine
Start small: 50–100 ml daily for a week to let your gut adapt.
Ways to enjoy it: Blend it into mango lassi, pour over granola, use as a salad dressing, or even marinate paneer.
Make it at home: Buy kefir grains online, add to milk, ferment for 24 hours, strain, and store in the fridge. The grains last indefinitely.
Avoid sugar traps: Stick to plain kefir with no more than 5–6g sugar per 100 ml.
Quick 7-Day Kefir Starter Plan
Day What to Try
1–2 50 ml plain kefir with honey
3–4 100 ml kefir smoothie (banana + mango + cardamom)
5–7 150 ml kefir lassi with mint and a tadka of jeera
Track how you feel—digestion, energy, mood, skin.

Dementia affects women more than men: Causes, risks, and solutions
Dementia is a broad term describing a decline in cognitive function that impairs memory, thinking, and daily functioning. While it affects both men and women worldwide, research consistently shows that women are disproportionately affected by dementia, especially Alzheimer's disease — the most common form. This article explores the reasons behind this gender disparity, covering biological, genetic, brain structure, and social factors that contribute to women's higher risk. We also discuss prevention strategies and the importance of early diagnosis. Women over 60 face nearly double the risk of Alzheimer's compared to men Women over 60 are nearly twice as likely to develop Alzheimer's disease compared to men of the same age. This increased risk is not simply explained by women's longer average lifespan, even though age is the greatest risk factor for dementia. Experts emphasize that additional biological and social factors contribute to this imbalance. According to Alzheimer's Research UK, 'women are bearing more of the impact of dementia,' pointing out that the higher incidence is not solely due to longevity but other underlying causes. Biological and genetic factors driving higher dementia risk in women One critical biological difference lies in hormonal influences, particularly estrogen. Estrogen has neuroprotective properties that help maintain brain health, support memory, and reduce inflammation. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Seniors are going crazy for these comfy, stylish, easy-on shoes Ultra-Comfortable Shoes Undo However, during menopause, estrogen levels sharply decline, which scientists believe increases women's vulnerability to Alzheimer's and other dementias. Harvard Health Publishing explains that the loss of estrogen's protective effects may accelerate cognitive decline in postmenopausal women, making this a crucial phase for brain health as reported. ApOE4 gene and genetic risks: Why women are more vulnerable to Alzheimer's Genetics also play a significant role. The APOE4 gene variant is the strongest known genetic risk factor for late-onset Alzheimer's disease. Research shows that women carrying the APOE4 gene face a higher risk of developing Alzheimer's compared to men with the same gene. Scientists from the USC Leonard Davis School of Gerontology highlight that understanding why APOE4 affects women more profoundly could unlock new avenues for personalized treatments (USC Gerontology Research, 2024). Studies also reveal that women tend to accumulate more beta-amyloid plaques, a hallmark of Alzheimer's pathology, than men of similar age. This greater buildup may explain why women experience more severe or earlier symptoms. Moreover, women's brains may be differently affected by tau protein tangles, another key Alzheimer's feature as reported. Social and lifestyle influences contributing to women's dementia risk Women often take on primary caregiving roles for family members with dementia. This responsibility leads to chronic stress, reduced self-care, and social isolation — all recognized risk factors for cognitive decline. The mental and physical toll of caregiving can indirectly increase women's own dementia risk. The Alzheimer's Association emphasizes the importance of supporting caregivers with resources and respite to protect their health and reduce risk as reported. Lifestyle factors and dementia risk: How healthy habits protect women's brain health Beyond caregiving, lifestyle choices strongly influence dementia risk. Studies show that social isolation, sedentary behavior, and poor diet increase the chance of cognitive decline. Older women may face greater social isolation due to widowhood or mobility challenges. Maintaining a healthy lifestyle with regular physical activity, balanced nutrition, and social engagement is widely recognized as a key strategy to reduce dementia risk. Detecting dementia symptoms early can improve outcomes Early diagnosis of dementia enables better management and improved quality of life. Since women are at higher risk, raising awareness about early warning signs is critical. Healthcare providers encourage routine cognitive screening for older women, particularly those with family history or genetic risk factors (Harvard Health Publishing, 2022). Healthy habits to lower dementia risk As reported by Harvard Health Publishing, 2022 and BrightFocus Foundation, 2023, experts recommend adopting brain-healthy habits such as: Engaging in regular exercise to improve blood flow and brain plasticity Eating a Mediterranean-style diet rich in fruits, vegetables, and healthy fats Staying mentally and socially active to strengthen cognitive reserves Managing cardiovascular risks like hypertension and diabetes, which can worsen dementia progression Also Read | Harvard-trained gastroenterologist shares 10 easy morning habits for better gut health, smoother digestion, and lasting energy

Scientists Are Finally Making Progress Against Alzheimer's
Buck up, baby boomers. Sixty may not be the new 40, but 80 could soon be the new 60. A trove of new Alzheimer's research suggests that medicines and lifestyle changes can not only slow but prevent, even reverse, the debilitating disease. Alzheimer's is characterized by a buildup of amyloid plaque and tangles of tau proteins in the brain. They trigger inflammation, which in turn causes cognitive decline and neuron death. Scientists don't know exactly what causes this destructive cascade. The disease's complexity stymied the quest for treatments for decades, but no more. Scientists are learning quickly. The only two approved treatments for Alzheimer's that can slow progression—developed by Eli Lilly and Biogen-Eisai—work by removing amyloid plaque. They reduce cognitive decline by 25% to 36% over 18 months compared with a placebo group in clinical trials. Those in the earliest stages of the diseases saw bigger benefits, and nearly half of those in the Lilly trial showed no progression after a year. Some back-bench scientists who don't treat Alzheimer's patients dismiss such benefits as not meaningful. But the medications could mean more years when your mother recognizes you. Who wouldn't find that meaningful? Recent follow-up studies have also shown that the benefits grow over time—doubling over three years for Eli Lilly's treatment and quadrupling over four years for Biogen-Eisai's. Drugmakers are studying whether eliminating amyloid can ward off Alzheimer's in preclinical patients—those without cognitive symptoms—as statins can prevent cardiovascular disease. Lifestyle changes can augment the benefits. A recently published randomized trial found that a 'treatment' of regular physical and cognitive exercise, nutritious diet and social engagement improved cognitive performance among previously sedentary older adults at risk of dementia. A smaller study earlier this summer found such lifestyle interventions improved metal acuity of early-stage Alzheimer's patients, as well as physiological measures of brain health. The treatment group in the latter study also showed an increase in beneficial bacteria in their guts. Why is this notable? Studies have found that microbiomes of Alzheimer's patients differ from those of healthy seniors. For one, Alzheimer's patients have lower levels of Akkermansia muciniphila, a bacterial strain that produces the short-chain fatty acid propionate from dietary fiber. Propionate helps regulate appetite as well as brain inflammation and amyloid buildup. In one study, propionate was found to reduce brain inflammation and amyloid in mice with the rodent version of Alzheimer's disease. So perhaps a probiotic cocktail or more fiber in the diet could slow progression, much like antiamyloid treatments. Another potential antidote: lithium salts. A study published last week in the journal Nature found that amyloid can trap lithium, resulting in a deficiency of the mineral. Lithium protects neurons. Mice given a lithium-deficient diet had more amyloid, damaged neurons and impaired learning and memory. A low dose of lithium orotate reversed cognitive problems and restored memory. How the microbiome and lithium affect Alzheimer's is the sort of basic scientific research that deserves more government attention and funding. Ditto the effects of viruses and vaccines. Take herpes viruses, which cause chickenpox, shingles and cold sores. Most seniors have been infected by at least one type of herpes virus. After an initial infection, the virus lies dormant in cells, including in the brain. Reactivation of the virus has been linked to increased amyloid buildup, brain inflammation and risk of dementia. Vaccines and antivirals may be able to help prevent Alzheimer's. A quasirandomized control trial earlier this year found that people vaccinated for shingles were 20% less likely to develop dementia. Recent research has also found that head injuries increase amyloid and brain inflammation by reactivating herpes viruses. So perhaps administering herpes antivirals after concussions could help protect the brain. Alzheimer's tends to run in families, and the APOE4 variant is the biggest genetic risk factor. Women with one copy, inherited from mom or dad, are at four times as much risk. Those with two, one from each parent, have 10 times the risk. Men with one variant show no increased risk, and those with two copies are at fourfold increased risk. You can't change your genes, but an experimental cholesterol drug was recently found to reduce Alzheimer's hallmarks in APOE4 carriers in a late-stage trial. Perhaps that's because APOE4 can cause cholesterol to build up in the brain. All these studies underline the potential to stop Alzheimer's dead in its tracks—as long as the Food and Drug Administration doesn't get in the way. The Health and Human Services Department on Saturday announced that Vinay Prasad was returning as the FDA head of biologics and gene therapies. Dr. Prasad stepped down late last month after a public backlash over his scuttling of a gene therapy for Duchenne muscular dystrophy. He's shown similar hostility to Alzheimer's treatments. In a tweet last summer referencing Biogen-Eisai's antiamyloid treatment, he wrote that paying 'someone to come to an Alzheimer's patients house and help with the dishes' would do more good than 'funding these garbage drugs.' Tell that to the poor souls afflicted by Alzheimer's and their families who have years more of quality life together.
