Is caffeine healthy?
Consuming moderate amount of caffeine does no harm. According to the Mayo Clinic, most healthy adults can safely consume 400mg of caffeine a day.

Is drinking coffee healthy?
The answer tends to change over time, but the current wisdom is that drinking coffee can be healthy. There are studies that found potentially correlated health benefits such as protection against liver disease, diabetes (type 2) and Parkinson’s, in addition to improving cognitive function and preventing the onset of depression. On the flip side, drinking unfiltered coffee has been shown to result in higher cholesterol levels.
Why does drinking coffee increase cholesterol?
To be precise, only drinking unfiltered coffee (such as French press and boiled coffee) increases cholesterol. This is because coffee contains a natural oil called cafestol. After roasting, cafestol remains in the beans together with the aromatic oils. Cafestol is known to activate the bile acid receptors in the intestine to release more cholesterol, and most of this cholesterol is LDL, also known as bad cholesterol. When brewing with a coffee filter, most cafestol oil gets trapped in the filter and this is why only drinking unfiltered coffee can expose one to this risk.
