Tea vs Coffee: Which Is Healthier?
You wake up torn between pouring a hot cup of coffee or starting your morning with tea. Both drinks are staples for millions, but which one is actually better for your health? This isn’t just about taste or energy—it’s about what each beverage really does to your body over time.
Quick answer: Neither tea nor coffee is strictly healthier overall. Tea helps reduce stress hormones, may lower diabetes and obesity risks, and some types protect against cancer. Coffee protects against liver disease, Alzheimer’s, and may boost memory—but it can also stain teeth and raise heart risks in excess. Your choice should depend on your personal health priorities.
What Makes Tea Healthy?
Tea, especially varieties made from the young leaves and buds of the tea plant, contains high levels of antioxidants. These compounds are linked to several health protections:
- Regular consumption of black tea (four cups per day for six weeks) has been shown to significantly lower stress hormone levels (cortisol).
- Green tea may reduce oesophageal cancer risk in women by up to 60%.
- White tea, made from the youngest tea leaves, has even more concentrated antioxidants. It may help combat ageing, inhibit fat cell growth, and prevent cancer.
Tea’s Potential Risks
Despite its benefits, tea is not without concerns:
- Even “organic” tea may contain pesticide residues.
- Tannins in tea can interfere with iron absorption, increasing the risk of anaemia.
- Drinking tea that is too hot may raise the risk of oesophageal cancer.
What Are the Health Benefits of Coffee?
Coffee is often underestimated in health discussions, but it offers multiple advantages backed by research:
- It may help prevent gout, liver damage, and liver cancer—especially in middle-aged men.
- Coffee consumption is associated with a delay in the onset of Alzheimer’s disease.
- It can enhance the effectiveness of painkillers, improve short-term memory, and increase reaction times in older adults.
- Scientists are exploring coffee’s chemical compounds for potential new treatments for heart disease and insomnia.
Coffee’s Possible Downsides
However, drinking coffee also comes with risks:
- Excessive coffee intake may reduce blood flow to the heart.
- It can cause tooth discolouration over time.
- A Danish study found that drinking more than eight cups of coffee per day significantly increases the risk of stillbirth in women.
- Many health studies refer to black coffee with minimal sugar and milk—not the high-calorie coffee shop drinks.
Are Coffee and Tea Actually Dehydrating?
No. The long-held belief that coffee and tea dehydrate you is a myth. While both have diuretic properties, moderate consumption contributes to your daily fluid intake.
What About Sugary Coffee Drinks?
Nutrition expert Duane Mellor from the University of Nottingham warns against confusing coffee with sugary, calorie-laden beverages. He points out that many festive drinks from major coffee chains contain more sugar than the recommended daily intake. A single syrup-heavy latte can deliver excessive calories, sugar, and fat, turning it into a completely different kind of drink. And contrary to popular belief, standard black coffee and tea aren’t inherently dehydrating.

Mellor doesn’t suggest giving up coffee or tea. In fact, he argues that both are better choices than sugary soft drinks. “Traditionally tea was seen as the healthier option,” he says, “but newer research shows coffee has many benefits too. It’s not clear-cut—choose based on what you like.”
Frequently Asked Questions
Does tea really lower stress hormone levels?
Yes. A study showed that drinking four cups of black tea per day for six consecutive weeks led to a measurable reduction in cortisol, the primary stress hormone. This suggests regular black tea intake may help manage stress levels over time.
Can green tea really reduce oesophageal cancer risk in women?
Yes. Research indicates that drinking green tea may lower the risk of oesophageal cancer in women by as much as 60%. The exact mechanisms are not fully understood, but antioxidants in green tea are believed to play a protective role.
Is white tea better for anti-ageing than other teas?
White tea, made from the youngest tea leaves and buds, contains higher concentrations of antioxidants compared to other tea types. These compounds may help fight ageing, inhibit new fat cell formation, and offer cancer protection, though more research is needed to confirm specific effects.
Does hot tea increase the risk of oesophageal cancer?
Yes. Drinking tea that is too hot has been linked to a higher risk of oesophageal cancer. It’s advisable to let tea cool to a safer drinking temperature before consuming.
Is coffee bad for your heart?
In excess, yes. Some studies show that high coffee intake may reduce blood flow to the heart. However, moderate coffee consumption is not linked to increased heart disease risk for most people and may even offer cognitive and liver benefits.
Do coffee and tea dehydrate you?
No. Despite common belief, neither coffee nor tea is inherently dehydrating when consumed in normal amounts. They contribute to your overall fluid intake despite having mild diuretic properties.
Are lattes and flavoured coffee drinks unhealthy?
Many are. A University of Nottingham expert warned that popular holiday lattes from coffee chains can contain more sugar than the daily recommended limit. These high-calorie drinks often include syrups, cream, and excess sugar, making them very different from plain black coffee or tea.
