Gut issues? 6 drinks recommended by Stanford doctor could be your cure

In a world flooded with energy drinks, carbonated sodas, and sugar-laden smoothies, your gut might just be begging for something gentler—and smarter. According to Stanford-trained gastroenterologist Dr. Saurabh Sethi, the secret to better digestion and a healthier gut doesn’t lie in fancy supplements or detox fads. It’s in your kitchen—or at least your nearest grocery store. From kefir to coconut water, Dr. Sethi highlights simple, accessible beverages that can support everything from constipation and bloating to diarrhoea and liver health.

1. For gut healing: Kefir or buttermilk
Kefir tops the list when it comes to restoring your gut microbiome. This fermented milk drink is loaded with probiotics, including Lactobacillus kefiri, a powerful bacteria known to fight harmful microbes like Salmonella and E. coli. Buttermilk also gets a nod from the Harvard graduate for its lactic acid content, which boosts acidity, extends shelf life, and wards off unwanted bacterial growth—all while lending it that signature tangy taste.


2. For digestion: Ginger tea
There’s a reason ginger tea is a go-to home remedy across generations. Warming and soothing, it’s especially effective after a heavy meal or during colder months. Whether brewed from dried ginger tea bags or steeped from fresh ginger root, this spicy-sweet drink stimulates digestion and calms the stomach. A slice of lemon and a drizzle of honey turn it into a treat that heals and satisfies.

3. For constipation: Prune juice
If you’re battling sluggish bowels, reach for prune juice instead. Studies have found that prunes are rich in fibre and sorbitol and naturally encourage bowel movements and help relieve chronic constipation, a common issue in older adults and young children alike.

4. For bloating: Peppermint tea


Peppermint tea is more than just refreshing—it can actually calm your gut. Animal studies show that peppermint relaxes the digestive tract, preventing painful spasms and reducing gas. You can make it from store-bought tea bags or steep a handful of fresh leaves at home. Bonus: it's caffeine-free, so you can sip it any time of day.

5. For diarrhoea: Coconut water


Coconut water is a naturally hydrating drink and a popular alternative to commercial sports beverages. Rich in essential electrolytes like potassium, sodium, magnesium, and calcium, it helps maintain the body’s fluid balance. Thanks to this nutrient profile, coconut water is especially beneficial during bouts of diarrhoea, when the body loses fluids and electrolytes. In fact, studies have shown that coconut water is effective in treating mild dehydration caused by diarrhoea and performs on par with sports drinks when it comes to replenishing lost electrolytes.

6. For fatty liver: Black coffee
Dr Saurabh Sethi claims that the best beverage for those with fatty liver is black coffee.
