Apart from mineral water, black tea is one of the most consumed beverages in the world. It comes from Camellia sinensis leaves. Black tea contains caffeine as well as stimulants and antioxidants. To produce black tea requires a process called oxidation. The goal is to change the green color of the leaves to brownish-black.
The health benefits of black tea
1. Has a high antioxidant content
Black tea contains a group of polyphenols that have antioxidant properties. Foods or drinks containing antioxidants can help reduce your risk of chronic disease and improve your overall health.
2. Maintain heart health
Black tea contains flavonoids which are beneficial for heart health. Research has proven that regularly drinking black tea can help reduce the risk of heart disease. The flavonoid content can also help prevent bad cholesterol, so it doesn't clog blood flow to the arteries.
3. Improve focus and alertness
Black tea can help improve focus due to its caffeine content and an amino acid called L-theanine. This amino acid increases alpha activity in the brain, which can help improve focus and alertness. This makes black tea a great choice if you want to improve your energy and focus without much caffeine.
4. Improve the digestive system
The gut hosts trillions of bacteria and a large part of your immune system. The polyphenols and antimicrobial properties of black tea can help to improve gut health and immunity.
In addition, drinking black tea can also help reduce the risk of intestinal inflammation and the formation of kidney stones.
5. Lower blood sugar levels
Insulin is a hormone released when you consume sugar. Black tea is an excellent non-sweet drink that can help increase insulin use, thereby reducing blood sugar levels.
Black tea side effects
Drinking black tea in moderation is generally safe for most people. However, the amount of daily consumption also needs to be considered because side effects may occur.
Drinking large amounts of black tea, for example, more than four or five cups a day, can cause health problems. Most of these are due to caffeine-related side effects.
Some of the side effects that can be caused by black tea include:
- hard to sleep
- nervous
- headache
- frequent urination
- heart pounding
- nauseous
- vomiting
- breathe quickly
- anemia
Black tea is a great option if you're looking for a low-calorie, unsweetened drink with less caffeine than coffee or energy drinks. Black tea has a strong, unique taste and is high in antioxidants, which may provide several health benefits.
If you have health problems related to caffeine, make sure you consult your doctor first.
