Coffee is something that people don’t mind trying it… there are so many of my friends that I know who love coffee and don’t mind having it at least 4 times a day! Well coffee does taste good and helps you be more active and non- sleepy during lectures or it is useful to have them the day before exams so you know that you wont fall asleep. it’s in a way to a girl’s heart. All these places “cafe coffee day”, ” Starbucks” etc have such delicious coffee that really tempting. But here are certain things a coffee could do to your body. some things that you wouldn’t have even thought about it. so here are 5 major negative effects that you didn’t know coffee could do to you…
1: Hydroelectric Acid
Drinking coffee on an empty stomach, such as first thing in the morning, stimulates hydroelectric acid production. This can be a problem because HCl should only be produced to digest meals. If your body has to make HCl more often in response to regular cups of coffee, it may have difficulty producing enough to deal with a large meal. hence people who consume caffeinated beverages often report an upset stomach or indigestion.
2: Blood Pressure
Coffee has been recommended bad for those who have a high blood pressure…an experiment was done  wherein the people with hypertension were given 250 mg of caffeine (about 2 coffees) and the data revealed that their blood pressure was elevated for about 2-3 hours after the caffeine. A second study performed by The Mayo Clinic found similar results from a 160 mg dose. All participants experienced a marked rise in blood pressure and it was the most pronounced in those that didn’t normally consume caffeine.
3: Toxic
Bad coffee can be toxic. Bad quality coffee can have a lot of impurities in it, which can cause sickness, headache or a general bad feeling. This can happen if your coffee is made from beans that have been over ripped or otherwise ruined. Even one ruined bean can make your cup toxic. hence a person’s health is at risk.
4:  Harmful for pregnant women

 pregnant women can have coffee but in  a limit that’s what this  Studies on coffee’s effect on a fetus had been controversial, but one thing was sure that if a woman drinks coffee when pregnant, caffeine will also reach the fetus, and the baby is actually quite highly sensitive to caffeine. So, if you’re a heavyweight coffee drinker and can’t stop drinking it while pregnant, at least reduce your coffee intake to one cup a day.
5: Effect On Children
Coffee is a diuretic — it increases urine production. Increased urination causes the loss of calcium from the body, which can lead to bone loss. In addition to being a diuretic, it also contains large amounts of caffeine that leach calcium from the body. For every 100 mg of caffeine ingested, 6 mg of calcium are lost. For children, calcium is essential for bone growth.
