Curd and Buttermilk (Chaas) for Perimenopause: Gut Health, Calcium, and Cooling the Body

Somewhere around your mid-forties, you may notice you’re reaching for a bowl of curd with lunch more often than you used to, or asking for an extra glass of chaas after a heavy meal, almost instinctively. Maybe your mother always said curd “cools the body,” and now, mid-hot-flash, that advice suddenly makes a lot more sense. It turns out there’s more to this than nostalgia. Curd and buttermilk sit at the intersection of a few things that matter a great deal in perimenopause: calcium, gut bacteria, and temperature regulation. None of it replaces medical care, but as a daily dietary habit, it’s one of the more evidence-backed “grandmother remedies” out there.

Why does your body suddenly crave more curd and chaas in perimenopause?

It’s partly digestion, partly instinct. As oestrogen fluctuates, many women notice their gut becomes more reactive, heavier meals sit less comfortably, and spicy or oily food that was once fine now causes bloating or discomfort (a pattern covered in more depth elsewhere on this site). Curd and buttermilk are traditionally eaten precisely because they’re gentler on digestion than milk itself, the fermentation process breaks down some of the lactose and makes the proteins easier to absorb.

There may also be a real physiological pull toward cooling foods. Hot flashes and night sweats raise your perceived body temperature unpredictably, and foods that are traditionally considered “cooling” in Indian food culture, curd, buttermilk, cucumber, coconut water, genuinely do lower the subjective sense of heat for many women, even if the mechanism isn’t dramatic thermodynamics so much as taste, texture, and habit.

What’s actually in curd and buttermilk that matters for perimenopause?

A 200ml bowl of curd typically provides somewhere in the range of 200-250mg of calcium, depending on the milk it’s set from and how much whey has drained off. That’s comparable to a glass of milk, sometimes slightly more concentrated because of the fermentation process. It also provides roughly 6-8g of protein, relevant given that protein needs actually increase, not decrease, during perimenopause as the body becomes more prone to losing muscle mass.

Buttermilk is a different, lighter product. Made by diluting curd with water (and often adding roasted cumin, curry leaves, ginger, or a pinch of salt), it has less calcium and protein per glass than curd itself simply because it’s diluted, but it’s more hydrating and easier on a heavy stomach, which is why it’s traditionally served after rich or festive meals rather than as a primary calcium source.

Does curd help with hot flashes and heat sensitivity?

There’s no clinical trial showing that curd specifically reduces hot flash frequency or intensity. What exists is a more indirect, plausible case: curd and buttermilk are lower in the kind of fat and spice load that can trigger a hot flash in some women, they’re hydrating, and the ritual of a cool, familiar food after a meal can genuinely help you feel more settled when your system is running hot. Think of it as a comfort and prevention measure, not a treatment. If hot flashes are frequent and disruptive, that’s a conversation for your gynaecologist about hormone therapy or other evidence-based options, not something curd alone will resolve.

Is probiotic curd different from regular homemade dahi?

Store-bought “probiotic” curd is often fortified with specific, identified bacterial strains that have been studied for particular effects (digestive regularity being the most researched). Homemade dahi, set with a spoonful of starter culture, also contains live bacteria, but the exact strains and quantities are less standardized and more variable batch to batch. Both can support gut health; neither has specific perimenopause trial data behind it. If gut-hormone connections (the so-called estrobolome, the collection of gut bacteria that help metabolise oestrogen) interest you, that’s a deeper and more complex topic covered separately on this site; curd is one small, plausible contributor to that ecosystem, not the whole story.

When curd and buttermilk might not agree with you

Not every body tolerates dairy equally, and this can shift in perimenopause too. Some women develop new sensitivity to dairy around this time, experiencing bloating, excess mucus, or digestive discomfort they didn’t have before. If that’s you, there’s no obligation to force curd into your diet; calcium and protein can come from plenty of other sources (sesame seeds, ragi, leafy greens, lentils, and if needed, supplements under a doctor’s guidance). Curd set in reactive metal vessels, or very old, over-fermented curd, can also be more acidic and harder on a sensitive stomach, so freshness matters more than people realise.

In the Indian context, the quality and fat content of curd varies enormously depending on whether it’s made from full-fat buffalo milk, cow’s milk, or a packaged toned-milk version, so “a bowl of curd” isn’t a fixed nutritional quantity the way a supplement label would be. If you’re tracking calcium intake carefully because of osteoporosis risk or a DEXA scan result, it’s worth discussing actual quantities with your doctor rather than assuming curd alone covers your needs.

Frequently Asked Questions

Is curd better than milk for perimenopause bone health? Not necessarily better, just different and easier to digest for some people. Both provide meaningful calcium; curd has the added benefit of live cultures and is often gentler on a lactose-sensitive gut because fermentation partially breaks down the lactose.

Can buttermilk actually reduce hot flashes? There’s no clinical evidence that it directly reduces hot flash frequency. It can help you feel more comfortable and hydrated around a flash, and its light, cooling quality is a reasonable part of an overall diet, but it isn’t a substitute for medical treatment if hot flashes are severe.

How much curd should I eat daily in perimenopause? There’s no official perimenopause-specific guideline. A bowl (150-200ml) with one or two meals is a reasonable, traditional amount for most people without dairy intolerance. If you have specific calcium targets because of bone density concerns, ask your doctor to help you work out your actual daily intake across all sources.

Is it true that curd should not be eaten at night? This is a common belief in parts of Indian food culture, largely tied to Ayurvedic ideas about curd’s effect on mucus and digestion after sunset, rather than modern clinical evidence. If night-time curd doesn’t bother your digestion, there’s no strong reason to avoid it; if you notice congestion or sluggish digestion the next morning, it may be worth experimenting with earlier timing instead.

Can I rely on curd instead of a calcium supplement? That depends entirely on your individual calcium levels, diet, and bone density, which only your doctor can assess properly. Curd is a genuinely good calcium source, but if you’ve been told you need supplementation because of a bone scan result or lab test, food alone may not be enough, and that’s a conversation to have directly with whoever ordered that test.
