Coffee vs Tea: Which Is Better for Daily Drinking?

Every morning, millions face a choice: coffee or tea? For some, nothing but a strong cup of coffee will shake off the grogginess. Others swear by a gentle cup of tea to start the day right. But beyond habit and taste, which one actually does more for your body? We dig into the real science behind both drinks.

The short answer? Both coffee and tea offer health perks—but also risks. Most studies suggest drinking moderate amounts (like black coffee with a little milk or standard black tea) is better than sugary café drinks. But exact benefits depend on how you prepare them, how much you drink, and what you add.

What Science Says About Coffee’s Health Effects

Coffee contains unique chemical compounds that researchers have even explored for pharmaceutical use—specifically in treating conditions like heart disease and insomnia. However, not all the news is positive. Some studies show that coffee can reduce blood flow to the heart and may stain your teeth over time.

One Danish study found that women who drank eight or more cups of coffee per day had a higher risk of stillbirth. Importantly, these studies mostly looked at plain black coffee with just a bit of milk or sugar—not the high-calorie, syrup-laden coffee drinks sold at cafés.

Nutrition expert Duane Mellor from the University of Nottingham pointed out that compared to sugary soft drinks, coffee and tea are healthier choices. But he warned that many coffee shop drinks packed with syrups, sugar, and fat should not even be considered real coffee. A latte loaded with flavored syrup can deliver excessive calories, sugars, and unhealthy fats.

On the plus side, coffee has been linked to a lower risk of type 2 diabetes, may help middle-aged men prevent gout, and could reduce the likelihood of Alzheimer’s disease. It’s also associated with a decreased risk of liver cirrhosis and liver cancer in men.

Tea’s Health Benefits—and Drawbacks

Tea drinkers have reasons to celebrate too. Research shows that regularly drinking tea can reduce the risk of diabetes, heart disease, and certain cancers. It may also help prevent obesity. One study revealed that people who drank four cups of black tea daily for six weeks experienced a notable drop in cortisol, the stress hormone.

However, adding milk to tea might cancel out some of its cancer-fighting benefits. And there’s a catch: tea leaves can carry pesticide residues, even when labeled organic. Additionally, tea is rich in tannins, which can interfere with your body’s ability to absorb iron, possibly leading to anemia.

Another concern is temperature. Drinking tea that’s too hot has been linked to a higher risk of esophageal cancer. But here’s a positive twist: drinking green tea may reduce the risk of esophageal cancer in women by about 60%.

How Preparation and Habits Change the Outcome

The way you take your coffee or tea—what you add, how hot it is, and how much you drink—has a huge impact on whether it’s good or bad for you. For example:

• Black coffee or tea with minimal additives tends to be healthier.
• Adding syrups, creamers, or too much sugar turns a healthy drink into a calorie bomb.
• Milk in tea may block some antioxidant effects.
• Extremely hot beverages increase esophageal cancer risk.
• Tannins in tea affect iron absorption, which is important to monitor if you’re prone to anemia.

Both drinks can fit into a balanced diet, but moderation and preparation matter far more than the drink itself.

Frequently Asked Questions

Can drinking eight cups of coffee a day really harm me?

Yes, according to a Danish study, women who drank eight or more cups of coffee daily had a higher risk of stillbirth. While the study focused on black coffee with minimal additives, such high consumption may also reduce blood flow to the heart and cause tooth staining.

Does adding milk to tea reduce its health benefits?

Yes. Research shows that adding milk to tea may cancel out some of its cancer-fighting properties. So if you're drinking tea for its antioxidant benefits, skipping the milk might be wise.

Is it bad to drink very hot tea?

Yes. Drinking tea that is too hot has been linked to an increased risk of esophageal cancer. However, green tea specifically has been shown to reduce esophageal cancer risk in women by around 60%.

Does tea interfere with iron absorption?

Yes. Tea contains tannins, which can hinder your body’s ability to absorb iron, potentially leading to anemia—especially if you already have low iron levels or dietary insufficiency.

Is black coffee healthier than sugary coffee shop drinks?

Absolutely. Plain black coffee with a little milk or sugar is far better for you than high-calorie, syrup-heavy coffee drinks commonly sold in cafés, which can contain excessive sugar and fat.

Does coffee help prevent any diseases?

Yes. Coffee has been linked to a reduced risk of type 2 diabetes, Alzheimer’s disease, liver cirrhosis, and liver cancer in men. It may also help prevent gout in middle-aged men.
