WHAT DOES THE MEDICINE SAY ABOUT THIS?
Tea and coffee are popular beverages worldwide, valued not only for their taste but also for their health benefits. Both contain bioactive substances that can have positive or negative effects on health. The following compares the most important aspects of these two beverages from a medical perspective.
1. Caffeine content and its effect on the nervous system
Coffee typically contains more caffeine than tea (about 80-100 mg per cup vs. 30-50 mg for tea).
Tea releases caffeine more slowly because it is bound to L-theanine, resulting in a gentler and longer-lasting effect on concentration.
Coffee stimulates the central nervous system more strongly and can lead to nervousness or palpitations more quickly.
Tea has a more calming effect, especially green and black tea due to the L-theanine.
Adaptogenic teas such as Rhodiola or Ashwagandha tea can help regulate stress reactions of the nervous system and have a balancing effect.
2. Effects on the cardiovascular system
Coffee can temporarily raise blood pressure, especially in people who rarely drink coffee.
However, regular coffee consumption is associated with a lower risk of cardiovascular disease.
Tea, especially green and black tea, contains flavonoids that help keep blood vessels healthy.
Studies show that tea can also reduce the risk of heart attack and stroke.
Adaptogenic teas such as ginseng tea promote blood circulation and can stabilize blood pressure.
3. Digestion and Metabolism
Coffee stimulates bowel activity and can have a laxative effect.
Tea tends to have a calming effect on the gastrointestinal tract.
Green tea can boost fat burning, which can be beneficial for weight management.
Coffee temporarily increases metabolism, but can also irritate the stomach lining.
Adaptogenic teas such as ginger or licorice root tea support digestion and help reduce inflammation in the gastrointestinal tract.
4. Antioxidants and protection against diseases
Both drinks contain many antioxidants that can help against cell aging and chronic diseases.
Tea is particularly rich in polyphenols, which have anti-inflammatory properties.
Coffee contains chlorogenic acid, which can regulate blood sugar.
Studies suggest that both drinks may reduce the risk of type 2 diabetes.
Adaptogenic teas, such as turmeric tea, contain powerful antioxidants that support the immune system and prevent cell damage.
5. Effects on the brain and the risk of neurodegenerative diseases
Coffee has been associated with a lower risk of Alzheimer's and Parkinson's disease.
Tea also has neuroprotective properties, especially due to L-theanine and catechins.
Long-term consumption of both beverages can improve cognitive performance.
Adaptogenic teas such as Tulsi tea (holy basil), Brahmi or Ginseng can help maintain cognitive function and regulate stress hormones, which may help reduce the risk of age-related brain diseases.
6. Dental health
Tea contains fluoride, which can protect against tooth decay.
Coffee can cause tooth discoloration, but so can tea.
Both drinks contain tannins, which can inhibit the absorption of iron from plant-based foods.
Adaptogenic teas such as goji berry tea can have an anti-inflammatory effect on the gums and support the oral microbiome.
7. Sleep and stress
Coffee can disrupt sleep more than tea.
Tea, especially chamomile or herbal tea, can have a calming effect.
Green tea contains L-theanine, which can promote relaxation.
Adaptogenic teas such as ashwagandha or lavender tea have a relaxing effect and help to reduce stress and improve sleep.
Whether tea or coffee is better depends on individual needs. Those who prefer a gentle and long-lasting effect are well-advised to choose tea. Coffee, on the other hand, offers stronger stimulation and can improve cognitive performance in the short term. Adaptogenic teas offer a natural way to regulate stress and promote well-being. Both beverages have health benefits as long as they are consumed in moderation.
