The potential health benefits of drinking coffee are exciting news, but that doesn’t mean more is better. For some people, coffee can cause irritability, nervousness or anxiety in high doses, and it can also impact sleep quality and cause insomnia. In people with hypertension, coffee consumption does transiently raise their blood pressure — although for no more than several hours — but no correlation has been found between coffee drinking and long-term increases in blood pressure or the incidence of cardiovascular disease in patients with pre-existing hypertension.
Historically, it was first recorded as a drink just over 500 years ago, beginning on the Arabian peninsula, but there is a speculation that its use as a stimulating beverage stretches back more than 1,000 years in various ancient and indigenous cultures. Now, it is consumed in nearly every country of the world, and almost daily, even 5-6 times a day. While offices have larger machines, at home people often have single serve coffee makers which work best for the small requirements.

To put this in perspective, the World Health Organization recommends that adults consume 25 grams (or less) of sugar per day. One daily unhealthy choice when it comes to coffee, and you can say hello to 5 or 10 extra pounds in a month or two. To give you another example, a typical Frappuccino can weigh in at 66 grams of sugar – yikes. Drinking coffee black is a simple way to avoid all of these issues, but I will also give you some extra delicious tips to help spice things up.

This, it does so by protecting the heart’s muscular chamber against artery damage that may result from inflammation.

While they say that the results support moderate coffee drinking as a relatively healthy habit, both Poole and Guallar say the findings don’t go far enough to prompt anyone to change their coffee-drinking habits in the hopes of improving their health. The study did not confirm, for example, that people who do not currently drink coffee should start adding a cup or two a day in order to lower their risk of getting heart disease or any of the other chronic conditions studied. The data also do not support the idea that current coffee drinkers should drink even more coffee to enhance whatever benefits they might be receiving. Too much coffee, the data suggest, starts to bend the benefit curve back down.
