Tea vs. Coffee: Which Is More Likely To Affect Your Digestion?

Quick answer

• Coffee is a well-known stimulant that can get your digestive system moving.
• Tea, especially certain types, can also have a mild laxative effect.
• The caffeine content in both drinks plays a role, but other compounds are involved too.
• Acidity in coffee can sometimes irritate the stomach lining.
• Individual sensitivity varies greatly. What affects one person might not affect another.
• Your brewing method and what you add to your drink matter too.

Key terms and definitions

• Caffeine: A natural stimulant found in coffee beans and tea leaves. It can increase muscle contractions in your digestive tract.
• Acidity: The pH level of a beverage. Coffee tends to be more acidic than most teas.
• Tannins: Compounds found in tea (and wine) that can sometimes affect digestion. They can bind to proteins.
• Diuretic: A substance that promotes the production of urine. Both caffeine and some teas can have this effect.
• Laxative effect: The tendency to stimulate bowel movements. Coffee is famous for this.
• Gut microbiome: The community of microorganisms living in your digestive tract. What you consume can influence it.
• Gastric acid: Stomach acid that helps break down food. Coffee can sometimes increase its production.
• Irritable Bowel Syndrome (IBS): A common disorder that affects the large intestine. Certain foods and drinks can trigger symptoms.

How it works

• Both coffee and tea contain caffeine. Caffeine is a stimulant. It tells your colon to get moving. Think of it like a gentle nudge for your bowels.
• Coffee’s effect is often stronger. It’s not just the caffeine. Coffee can stimulate the release of gastrin. That’s a hormone that speeds up digestion. It also increases bile acid secretion, which helps break down fats.
• Tea, particularly black and green tea, also has caffeine. So, it can have a similar, though usually milder, effect.
• Some teas contain compounds called catechins. These are antioxidants. They might also play a role in how tea affects your gut.
• The acidity of coffee is another factor. For some people, the higher acidity can irritate the stomach lining. This can lead to discomfort or a faster trip to the bathroom.
• Herbal teas are a different story. Many are naturally caffeine-free. They might have soothing effects rather than stimulating ones. Chamomile, for example, is often used to calm an upset stomach.
• The process of roasting coffee beans can create compounds that affect digestion. This is less of a factor with tea processing.
• Basically, it’s a combination of stimulants, hormones, acidity, and unique compounds in each drink.

If you’re looking for soothing options, consider exploring a variety of herbal teas. Many are naturally caffeine-free and can offer gentle digestive support.

What affects the result

• Coffee Roast Level: Darker roasts tend to be less acidic. This might be easier on some stomachs. Lighter roasts can be more acidic.
• Type of Tea: Black tea and green tea have caffeine. Herbal teas (like peppermint or ginger) are usually caffeine-free and can be soothing.
• Caffeine Content: Higher caffeine levels in either drink will generally lead to a stronger digestive response. Check labels if you’re sensitive.
• Acidity of the Brew: Coffee is naturally more acidic than most teas. This can be a major factor for sensitive individuals.
• Brewing Method: How you brew your coffee or tea can affect the extraction of compounds. A long steep time might pull out more of certain elements.
• Additives: Milk, cream, sugar, or artificial sweeteners can all impact your digestion differently. Dairy can be an issue for lactose-intolerant folks.
• Freshness of Beans/Leaves: Older coffee beans or tea leaves might lose some of their volatile compounds. This could subtly alter their effect.
• Water Temperature: Too hot or too cold water can affect how compounds are extracted from coffee grounds or tea leaves.
• Individual Sensitivity: This is huge. Some people are just more sensitive to caffeine or the acids in coffee.
• Gut Health: Your existing gut microbiome and overall digestive health play a big part. What works for one person might not work for you.
• Amount Consumed: Drinking a large mug of coffee will likely have a bigger effect than a small cup. Same goes for tea.
• Time of Day: Your body’s natural rhythms can influence how you react to stimulants.

• Reality: While some herbal teas are soothing, caffeinated teas can still have a laxative effect.
