Harvard Expert Reveals 'Cold Water Slows Digestion'; 9 Essential Drink Facts

Your digestive system plays a crucial role in your overall health. Thus, the foods you consume daily can have a profound effect on your general well-being.

While focusing on consuming whole foods is vital, everyday beverages such as water, teas, coffee, and others also make up a good part of our diet. Therefore, it's important to know their impact on our health.

In a post on Instagram on Wednesday, Dr. Saurabh Sethi, a gastroenterologist and liver specialist with training from AIIMS, Harvard, and Stanford University, revealed critical health facts regarding these daily beverages.

9 key points about daily beverages

Dr Sethi wrote in his post, “As a digestive health expert, here are 9 truths about daily drinks I’m eager to share. Which beverage do you believe is benefiting—or harming—your gut the most?” Here’s his advice on drinking cold water, avoiding fruit juices, and more.

1. Warm water > ice cold

Dr Sethi points out that drinking warm or room-temperature water is preferable to ice-cold water. He stated, “Chilled beverages can temporarily slow digestion. Start your morning with warm or room temperature water to enhance gut activity.”

2. Coffee acts as a gut stimulant

The specialist cautioned against excessive coffee consumption as it can disrupt bowel movements and concentration. He remarked, “Overconsumption (especially if on an empty stomach) can result in acid reflux, urgency, and nervousness.”

3. Green tea deserves more recognition

“It possesses anti-inflammatory properties, aids in metabolism, and stabilises gut flora. Moreover, L-theanine relaxes the mind while caffeine maintains alertness,” Dr Sethi clarified, elaborating on the gut-health benefits of green tea.

4. Forego the juice, consume the fruit

The consensus is that consuming fruits is preferable to their juices. Dr Sethi explains, “Juices equal a sugar surge without the fibre. Whole fruits provide fibre and antioxidants that your gut microbiota thrives on.”

5. Kombucha isn’t always the healthiest choice

The specialist warns that some kombucha brands are loaded with sugar. He advises choosing those with ‘<5g sugar per serving’, or opting for plain kefir or yoghurt drinks.

6. Herbal teas as natural remedies

“Turmeric, ginger, and fennel not only provide comfort but also reduce bloating, alleviate inflammation, and help repair the intestinal lining,” noted the gastroenterologist.

7. Chia or basil seed beverages aid digestion

According to the expert, chia and basil seeds absorb water to form a gel beneficial for the gut, feeding healthy bacteria and promoting digestive regularity.

8. Alcohol harms your gut, no exceptions

Dr. Sethi explained that even small quantities of alcohol disturb gut flora, increase intestinal permeability (known as 'leaky gut'), and disrupt sleep. He suggests, “Ensure proper hydration and moderation if consuming alcohol.”

9. Incorporate leafy herbs

Although small, leafy herbs provide substantial benefits for digestive health. “Mint, cilantro, parsley, and basil contain polyphenols that facilitate digestion and nourish beneficial bacteria,” Dr Sethi remarked. He recommends consuming them raw rather than cooked and using them generously, not merely as garnish.
