Tea in general is beneficial for the body. Both green and black tea come from the same plant (Camellia sinensis), however, they undergo different fermentation and oxidation processes.
Black tea is a fully oxidized tea, while green tea is not oxidized.
However, many people wonder which of the two drinks offers the most health benefits.
But let’s first look together at the advantages that each one offers, separately.
The benefits of green tea
Antioxidants in green tea can reduce the risk of certain cancers. Due to the fact that green tea is not fermented, it contains more catechins compared to black tea. Catechins are a subclass of flavonoids found in high concentration in the leaves of the Camellia sinensis plant.
There are four main catechins in tea: epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC), and epigallocatechin-3-gallate (EGCG). Epigallocatechin gallate (EGCG) contained in green tea contributes to the destruction of free radicals, which cause damage to DNA, proteins and lipids.
At the same time, green tea promotes cardiovascular health by reducing levels of bad cholesterol (LDL), while helping to protect good cholesterol (HDL). In addition, polyphenols (catechins) help lower blood pressure, while reducing the risk of type 2 diabetes.
Green tea also helps with weight management. Some studies suggest that the catechins in green tea can boost metabolism, helping to burn fat, which means it can contribute to weight loss.
Additionally, green tea has lower caffeine content compared to black tea. Combined with the amino acid L-theanine, green tea provides mild stimulation and stimulation, without the disturbing effects of caffeine.
The benefits of black tea
Similar to green tea, black tea offers heart-healthy benefits. Antioxidants in black tea, such as theaflavins and catechins, can help improve cardiovascular function by lowering blood pressure and strengthening blood vessel function.
Black tea is also rich in polyphenols. Its polyphenols act as prebiotics, supporting the growth of beneficial bacteria in the intestinal flora.
The healthy gut microbiome is directly linked to the digestion of food. Some studies report that the phytochemical compounds in black tea can help improve bone density, minimizing the risk of fractures and osteoporosis.
However, black tea contains a higher caffeine content, acting as a substitute for coffee, compared to green tea.
Regular consumption of black tea can also reduce the risk of various diseases, such as: diabetes mellitus, kidney stones and Parkinson’s disease.
Which of the two should I choose?
Choosing between green and black tea ultimately comes down to personal preference, as both have antioxidant properties and are excellent choices for a healthy beverage.
Their differences lie mainly in their processing methods. Green tea has a mild taste, is light and more aromatic, while black tea has a stronger aroma and astringent taste.
The L-theanine (amino acid) of green tea promotes relaxation and combined with caffeine can enhance cognitive function, without causing nervousness. Black tea also contains L-theanine, but in smaller amounts.
People who are also sensitive to caffeine are better off opting for green tea.
In conclusion, both types of tea offer multiple health benefits. Green tea only slightly outperforms black tea, since its processing can lead to the reduction of some beneficial compounds. Finally, for those whose primary concern is weight management, green tea has the advantage of boosting metabolism.
