What is Coffee?
Coffee is brewed from roasted, ground seeds of the coffee fruit. It is closely associated with Ethiopia, where the plant originated, and spread through Yemen and beyond. Depending on the method, the grounds may be steeped, filtered or pulled as espresso, producing anything from a light cup to a concentrated shot. Around the world, people drink it at breakfast, during work breaks or after a meal, often with milk or a little sugar. Plain coffee is very low in calories—about 2 per 100 g—and contains caffeine. For a lighter cup, keep it black or add just a splash of milk; it also pairs naturally with toast or a small pastry.

Frequently Asked Questions About Coffee
Does coffee dehydrate you?
No, moderate coffee drinking does not usually dehydrate you; the water in coffee contributes to fluid intake. Caffeine can briefly increase urination, especially in people who do not drink it regularly.
Does coffee help you poop?
Yes, coffee can stimulate bowel movements in some people by activating the digestive system. The effect can happen with decaf too, so it is not caused by caffeine alone.
Does coffee raise blood pressure?
Yes, caffeine can temporarily raise blood pressure, particularly in people who rarely drink coffee. If you monitor your blood pressure, avoid measuring it right after a cup; ask your clinician about caffeine if you take blood-pressure medication.
Is coffee safe during pregnancy?
Coffee can be consumed during pregnancy, but caffeine should be limited; many health authorities recommend no more than 200 mg per day. Caffeine also comes from tea, chocolate, and some soft drinks, so count those sources too.
Does decaf coffee have caffeine?
Yes, decaf coffee usually contains a small amount of caffeine rather than none. It can suit people reducing caffeine, but it may still affect those who are highly sensitive or need to avoid caffeine completely.
Is coffee before a workout a good idea?
Yes, coffee before exercise can improve alertness and may help performance because caffeine is a stimulant. Try it well before training rather than immediately beforehand if coffee tends to upset your stomach.
Can coffee cause acid reflux?
Yes, coffee can trigger or worsen heartburn in some people by irritating the digestive tract or contributing to reflux. If it repeatedly causes symptoms, try a smaller serving, avoid drinking it on an empty stomach, or switch to decaf.
What is the difference between espresso and drip coffee?
Espresso is made by forcing hot water through finely ground coffee under pressure, while drip coffee lets water pass through grounds by gravity. Espresso tastes more concentrated, but a larger drip serving can contain more total caffeine.
How should you store coffee beans?
Store coffee beans in an airtight, opaque container in a cool, dry place, away from heat and sunlight. Avoid the refrigerator, where beans can absorb moisture and odors; grind them shortly before brewing for fresher flavor.
Does coffee suppress appetite or help with weight loss?
Coffee may temporarily reduce appetite for some people, but it is not a reliable weight-loss method. Sweeteners, cream, and flavored syrups can add substantial energy, and caffeine should not replace meals.
