The age-old debate of coffee versus tea continues. As you sip your morning drink, have you considered which contains more caffeine or which is more beneficial for your health? Both coffee and tea come with proven health advantages, such as enhancing energy and strengthening immunity. However, moderation is key. Here’s a detailed comparison of the benefits and drawbacks of each, as explained by a nutrition specialist.

“Both coffee and tea offer potential health benefits, but their overall advantages depend on factors like the variety, cultivation methods, brewing techniques, and consumption levels,” explains Ilana Muhlstein, RDN. Let’s explore each in detail.
Coffee
Coffee consumption has been linked to numerous health benefits, such as lowering inflammation and promoting heart and gut health. “The caffeine in coffee is known to enhance focus and cognitive performance,” Muhlstein notes.
“Regular coffee intake has also been linked to a reduced risk of heart disease and diabetes. Research published in the American Journal of Clinical Nutrition found that coffee drinkers had a lower likelihood of coronary heart disease. Additionally, a meta-analysis in Diabetes Care revealed that moderate coffee consumption was tied to a decreased risk of type 2 diabetes.”
For those seeking a rapid caffeine boost and increased energy, coffee is an excellent option due to its higher caffeine content compared to tea. However, individuals with anxiety or insomnia should exercise caution, as coffee may exacerbate these conditions or interfere with sleep.
Tea
“Tea contains caffeine, which enhances cognitive function and alertness, but it also includes theanine, an amino acid that helps reduce stress,” explains Muhlstein. If you’re tackling a significant task or need intense focus, black or green tea can be your perfect choice—offering steady energy without caffeine jitters and stress relief to help you complete your project. “Green tea is packed with potent antioxidants, known as polyphenols, which may lower the risk of cardiovascular disease and certain cancers,” Muhlstein adds. “For those sensitive to caffeine, caffeine-free green tea or herbal tea provides the same health benefits without the stimulant.”
Tea is an excellent option for individuals sensitive to caffeine or dealing with anxiety or sleep issues. Certain teas can even aid sleep and provide relaxing effects. If coffee’s taste isn’t appealing, tea might be a better alternative.
What Are Antioxidants?
Antioxidants are substances that shield cells from oxidative stress and damage caused by free radicals (unstable molecules). By neutralizing these free radicals, antioxidants help lower the risk of chronic illnesses and support overall well-being.
Caffeine Content in Coffee and Tea
Both coffee and tea contain caffeine. An eight-ounce cup of coffee typically has around 95 milligrams of caffeine, whereas black tea contains about 50 milligrams, and green tea has roughly 30 milligrams. This means coffee delivers twice the caffeine of black tea and over three times that of green tea for the same serving size.
However, it’s important to monitor your caffeine intake. The FDA recommends consuming no more than 400 milligrams of caffeine daily, which equates to about four cups of coffee, eight cups of black tea, or around 13 cups of green tea.
| Type | Size | Caffeine |
|---|---|---|
| Coffee | 8 ounces | 95 milligrams |
| Espresso | 1.5 ounces | 150 milligrams |
| Green Tea | 8 ounces | 30 milligrams |
| Black Tea | 8 ounces | 50 milligrams |
Drawbacks of Too Much Caffeine
Excessive caffeine consumption can lead to negative side effects. “Overindulging in coffee may result in heightened anxiety, insomnia, and increased heart rate and blood pressure,” Muhlstein explains. “Additionally, coffee’s acidity can worsen symptoms for individuals with acid reflux or gastrointestinal problems.”
If you’ve consumed too much caffeine, you might experience the following symptoms:
- Restlessness
- Tremors
- Headaches
- Dizziness
- Dehydration
- Dependency (requiring more coffee or tea to achieve the same energy boost)
Decaffeinated coffee and tea contain minimal to no caffeine, and herbal teas such as chamomile, peppermint, or rooibos are naturally caffeine-free. However, keep in mind that a cup of "decaf" coffee or tea still contains around two milligrams of caffeine, as the decaffeination process removes about 97% or more of the caffeine from the beans.
Common Coffee and Tea Additives
Additives such as milk, sugar, and whipped cream are frequently used in coffee and tea, but they can diminish the health benefits by introducing extra calories, fats, and sugars, which may lead to health problems. For instance, high-fat additives like whole milk or whipped cream can raise bad cholesterol levels, while excessive sugar may elevate the risk of diabetes and heart disease.
Enjoying coffee and tea in their simplest form, free from excessive additives, allows you to fully benefit from their natural properties. However, if you wish to enhance the flavor or texture, consider using low-fat, unsweetened options. For instance, low-fat milk or unsweetened alternatives like almond milk can provide richness and taste without the extra fats and sugars.
You can also explore sugar-free creamers or artificial sweeteners, but always review the ingredient labels carefully. The health impact of artificial sweeteners remains debated. “For a natural touch of sweetness in your coffee or tea, consider using honey or coconut sugar, but be mindful of portion sizes,” Mulhstein suggests.
