In recent years, the trend of a healthy lifestyle has begun to spread in Indonesia. If at first, the ‘options’ for healthy living were practically limited, now you can easily find a row of sports studios, a variety of exciting health events, as well as various places to eat or shops that offer healthy food and drinks. So, from these healthy foods and drinks, there are many more choices. There are salads, granola bowls, chia seeds, cold-pressed juice, and kombucha. Kombucha is a tea fermented using bacteria and fungi. The fermentation process involved in making kombucha involves large numbers of good bacteria, which are known as probiotics. The kombucha recipe fermentation process is carried out to get a dark color on the tea. On the other hand, green tea is not fermented so that the color and taste are much fresher than black tea.
The process of making tea is different, making the contents of these two teas also different. Black tea has less antioxidant content because it goes through a fermentation process that makes antioxidant levels decrease. However, other ingredients are no less beneficial, the fermentation process can add theaflavins and thearubigers which are useful for maintaining antibodies in the digestive system. Well, these bacteria will help nourish the digestive system and immune system (fun fact: 80% of the immune system is located in the stomach area), because they will fight off bad bacteria and disease-carrying viruses. This combination of bacteria and fungi is also usually called SCOBY (Symbiotic Colony of Bacteria and Yeast). Once fermented, kombucha will be carbonated and contain vinegar, B vitamins, enzymes, probiotics, and high acid content, so it has many health benefits.
Whereas in green tea, you will get a fairly high source of polyphenol antioxidants, especially epigallocatechin-3-gallate (EGCG) which can protect you from cancer cells. Apart from antioxidants, a significant difference in the amount of black tea and green tea is caffeine content. Green tea contains only 9-50 milligrams of caffeine per cup. While black tea has a caffeine content of 42-72 milligrams per cup, this amount is still less than coffee.
