Coffee is one of the most popular hot drinks in the world, usually due to its high caffeine content. But drinking too much coffee can actually do more harm than good.
Coffee is a popular drink originally made from coffee beans.
Beans are the roasted fruit of the Coffea arabica bush, and it is cultivated in around 80 countries.
Most people drink coffee either because they like the distinctive taste or because they want to make the caffeine buzz.
Caffeine stimulates the nervous system, heart, and muscles, and helps people feel more alert and awake.

“Coffee and tea are incredibly healthy drinks,” said nutritionist Franziska Spritzler.
She wrote for the Healthline medical website: “Most types contain caffeine, a substance that can boost your mood, metabolism, and mental and physical performance.
“However, high doses of caffeine can have unpleasant and even dangerous side effects.
“To reap the benefits of caffeine without side effects, make an honest assessment of your sleep, energy level, and other factors that may be affected, and reduce your intake if necessary.
There is no set amount of coffee that you are allowed to consume each day.
But, in general, anything with up to 400 mg of caffeine per day seems to be safe for most adults.
A single cup of coffee can contain around 100 mg of caffeine, so it is advisable to avoid having more than four cups per day.
You should reduce the amount of coffee in your diet if you frequently develop headaches, sleeplessness, nervousness, or a rapid heartbeat.
