Tea or coffee, which one contains more caffeine?
Caffeine is found in many foods and beverages, including coffee and tea. It has many health benefits, but consuming too much may cause some side effects such as heart palpitations, anxiety, insomnia, chronic headaches, and more.
Tea leaves contain 3.5% caffeine, while coffee beans contain 1.1 to 2.2%. Although tea leaves seem to have higher caffeine content than coffee beans, what we end up drinking is coffee and tea, not tea or coffee directly. bean. More caffeine is released from the coffee beans during the coffee brewing process, and more coffee beans are used to brew a cup than tea leaves.
Therefore, 1 cup of brewed coffee usually contains more caffeine than 1 cup of tea.
Caffeine content of tea, which varies by tea variety
Black tea, green tea and white tea are made from the leaves of the same plant, Camellia sinensis, and what makes them different is the time of harvesting and the degree of fermentation of the leaves.
Black tea leaves are highly fermented, while white and green tea leaves are less fermented. So black tea produces a vivid red color and increases the degree of caffeine in the leaves infused with hot water. That is, black tea has the highest caffeine content. An average cup of black tea contains 50mg of caffeine, and can reach up to 90mg. Green tea contains 20-45 mg of caffeine per cup, while white tea contains about 6-60 mg, which is a big difference.
Matcha green tea is a high-caffeine tea, which usually comes in powder form and contains 35 milligrams of caffeine per half-teaspoon.
The soaking time when brewing tea also has a great impact on the caffeine content of the tea. The longer the brewing time, the higher the caffeine content.
The effects of caffeine take effect quickly, usually within 20 minutes to an hour after drinking.
If you're sensitive to the effects of caffeine, here's what you can do:
1. Drink tea with lower caffeine content, such as white tea
2. Brew the tea for a short time, within 1 minute.
3. Choose caffeine-free tea, such as herbal tea
4. Drink decaf/decaf coffee
To keep caffeine within a safe amount, it is recommended to drink no more than 400 mg of caffeine per day, or 200 mg of caffeine in one sitting.
People with heart disease, high blood pressure, arrhythmia, anxiety, migraine-prone people, and those taking certain medications should limit their caffeine intake.
Women who are pregnant or breastfeeding should also stick to no more than 200 mg per day. Approximately a 330ml cup of coffee. My suggestion is that women who are pregnant, preparing for pregnancy, or breastfeeding should try not to drink coffee, drink light tea at most, or choose decaffeinated products.
