Coffee Consumption and It's Long-Term Effects

January 12, 2023

Coffee was first introduced in India in 1670. That was a long time ago, and since then coffee is now a widely consumed beverage all around the world. In fact, in  2020/2021, around 166.63 million 60 kilogram bags of coffee were consumed worldwide, a slight increase from 164 million bags in the previous year. Strange as it may sound, it is the actual reality. 

Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain flowering plants in the Coffea genus. One can have coffee in various ways, like a latte, americano, cappuccino, espresso, cortado, macchiato, mocha, flat white, affogatto, irish coffee, etc. These are just the hot coffee drinks. The iced or cold coffee drinks consist of iced latte, iced americano, iced espresso, cold brew, nitro, frappuccino. 

How is Coffee Made? 

Did you know that coffee bean is not actually a bean? It’s a seed! 

The coffee bean is a seed of the coffee plant. When coffee is picked from the coffee plant, it’s in the form of red ‘cherries’. There’s usually two beans inside each cherry, with the flat side on the inside, and the round side facing out. 

The process of coffee making is quite simple. The process starts out with picking out the coffee cherries(fruit), and then the fleshy outer layer of the cherry is removed and what lefts out is the green coffee bean. 

After the green coffee bean is inspected, a small batch of them is roasted and ground for taste testing. 

After this, the coffee seeds are roasted, depending on the duration of roasting, they can be dark roasted too. 

The next is packaging which is very important to keep them fresh. 

The taste of the coffee depends on the proves of grinding, the more is the grinding, better will be the taste and flavour of it. 

Coffee lovers all over the world have the habit of going for their morning brew but they should also know about it’s long term effects as well as complications. In 1991, WHO had included coffee in a list of possible carcinogens too.
