Green Tea vs Black Tea: A Qualitative Comparison.
Tea is a widely consumed beverage all over the world. It is found in the form of white, white, and green tea last two being more popular.
Both green and black tea is made from the leaves of the Camellia sinensis plant but with the difference of oxidation during the processing of tea leaves. A higher degree of oxidation of black tea changes leaves color to dark brown and intensifies tea flavor. Let’s explore the differences further.
While green and black tea differs in color taste and, they may provide some of the same health benefits but to a different extent. Few compounds are unique to each tea variety.
Both Black and Green Tea can protect your heart
Both green and black tea is rich in a group of protective antioxidants called polyphenols.
Both teas contain flavonoids, a subgroup of polyphenols but in different amounts. flavonoids are good for heart health.
Whereas green tea is higher in epigallocatechin-3-gallate (EGCG), black tea is a rich source of theaflavins.
Studies on the animal have found that green and black tea preventing blood vessel plaque formation, effectively reduces LDL (bad) cholesterol and triglycerides in human blood.
Studies also found that both teas can lower your blood pressure.
All this reduces the chances of stroke and heart attack however green tea is found more effective in reducing the risk than black tea.
Both Black and Green Tea may boost brain function
Both teas contain the well-known stimulant caffeine however green tea (35 mg/ 230-ml tea approx.) has less caffeine than black tea (39–109 mg/230 ml tea) Caffeine blocks inhibitory neurotransmitters adenosine thus stimulates the nervous system. It also aids the release of mood-enhancing neurotransmitters like dopamine and serotonin and improves alertness, mood, vigilance, reaction time, and short-term recall.
Both teas also contain the amino acid L-theanine, which is absent in coffee.
The compound L-theanine triggers the release of gamma-aminobutyric acid (GABA) and assists in to release of the mood-enhancing hormones dopamine and serotonin which bring about relaxed alertness.
Green tea has more L-theanine than black tea.
Green tea is rich in the powerful antioxidant EGCG
Green tea is an excellent source of the potent antioxidant epigallocatechin-3-gallate (EGCG) besides other polyphenols like catechin and gallic acid. EGCG is responsible for many of green tea’s health benefits. Few Health benefits of EGCG in Green Tea:
- It can reduce the multiplication of cancer cells and also cause the death of cancer cells.
- may reduce the harmful effects of amyloid plaques in Alzheimer’s patients.
- has Anti-fatigue properties and has a calming effect on the human body.
- It also reduces the probability of fatty liver and also reduces the transmission of some viruses.
Though most of the research and studies on the EGCG in green tea has been carried out in test-tube or animal studies however it gives credibility to the long-reported benefits of green tea.
Black tea contains beneficial Theaflavins
Theaflavins are a group of polyphenols that are unique to black tea. These are 3–6% of all polyphenols produced during oxidation. These polyphenols protect the heart and blood vessels, mitigate the effect of free radicals on fat cells and may support your body’s natural antioxidant production.
The aflavins reducing inflammation increase availability of nitric oxide thus lower the risk of plaque formation in blood vessels. Theaflavins significantly reduce cholesterol and blood sugar levels promotes fat breakdown and is recommended for obesity management.
Which one should you drink?
Though the polyphenol composition of teas is different their beneficial effects for human health are similar but to varying extent.
Most research indicates that green tea has stronger antioxidant properties than black tea. Green tea has more L-theanine, an amino acid to reduce the ill effect of caffeine. Black tea is not a good choice for stimulant-sensitive people as it has more caffeine than green tea It must be noted that both teas have tannins that bind to minerals and reduce their absorption capacity.
Green tea leaves do not undergo a 100% oxidation process, and thus, retain key nutrients. When combined with the right diet and exercise it can help in weight reduction. Pure green tea also aids in detoxification which can boost overall health.
