Tea is needed at least once a day by most of the people. It helps provide a break and energy to go through the day. Both green and black tea is made from the leaves of the Camellia sinensis plant. The major difference between the two is that black tea is oxidized after extraction and green tea is not. In the process of making black tea, the leaves are first rolled and then exposed to air to trigger the oxidation process by using the oxygen in the atmosphere. This process causes the leaves to turn dark brown and enhances the flavors. Contrarily, green tea is processed to prevent oxidation and thus much lighter in color than black tea.
While green and black tea differ in the process of extraction and making, there are some shared benefits between the two.
Help to protect your heart
Both the teas are a rich source of protective antioxidants called polyphenols. Particularly they contain flavonoids, which is a subgroup of polyphenols. But the 2 differ in the type and amount of flavonoids they contain. Green tea contains a higher amount of epigallocatechin-3-gallate (EGCG), whereas black tea contains more of theaflavins. The flavonoids in tea are claimed to protect your heart. According to a study also, both types of tea help reduce LDL (bad) cholesterol and triglycerides. They are also claimed to lower your blood pressure. Additionally, drinking tea can help reduce your chances of having heart diseases also.
Helps boost brain function
Green and black tea both commonly constitute caffeine which is a known stimulant. Green tea is claimed to contain less amount of caffeine than black tea. Caffeine helps stimulate your nervous system and blocks the inhibitory neurotransmitter adenosine. It also helps in the release of mood-enhancing neurotransmitters like dopamine and serotonin. Thus, caffeine can help boost alertness, mood, vigilance, reaction time, and short-term memory. In addition to this, green and black teas also contain the amino acid L-theanine, which is not present in coffee. L-theanine is claimed to cross the blood-brain barrier and initiate the release of an inhibitory neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which leads to a relaxed but alert state. Additionally, it also promotes the release of mood-enhancing hormones dopamine and serotonin. L-theanine is considered to balance the effects of caffeine. The combination of these two substances is considered to be synergistic and can help have better attention.
The L-theanine in green tea is slightly more than that in black tea
Except for the common benefits, both these tea offer a list of uses uncommon to each other, owing to the difference in their composition and constituents.
Green tea is rich in the powerful antioxidant EGCG
Green tea is considered to be an excellent source of the potent antioxidant epigallocatechin-3-gallate (EGCG). Additionally, green tea also contains other polyphenols, such as catechin and gallic acid, but EGCG is considered to be the most likely responsible for many of green tea’s health benefits.
Here’s a list of the benefits of EGCG in green tea
Helps prevent Cancer growth
According to studies, EGCG in green tea can stop the multiplication of cancer cells and cause cancer cell death.
Helps in Alzheimer’s disease
EGCG helps reduce the harmful effects of amyloid plaques, which get collected in Alzheimer’s patients.
Helps curb fatigue
Studies suggest green tea helps delay exhaustion, thus delay fatigue.
Helps in Liver protection.
EGCG is claimed to reduce the development of fatty liver.
EGCG can cause damage to bacterial cell walls and reduce their ill effects.
Helps Calm the body
EGCG interacts with receptors in your brain to exert a calming effect on your body.theaflavins
Black tea contains beneficial theaflavins
- Theaflavins are the main constituent of black tea. They’re formed during the oxidation process. These polyphenols help protect fat cells from damage by free radicals and support your body’s natural antioxidant production.
- Additionally, theaflavins can lower the risk of plaque formation in blood vessels and reduce inflammation.
- Further, theaflavins also help to significantly reduce cholesterol and blood sugar levels.
- They also promote faster fat breakdown and help in obesity management
Hence one should pick the choice of tea on the basis of the heath benefits one wants to avail of.
