Which of you didn't dream of drinking coffee or eating lemon and not feeling the unpleasant sensation of heartburn? According to the scientific studies reports, a huge majority of people, each fifth person in the universe, have problems with stomach acidity. Thus, lots of us are forced to abstain from drinking coffee and eating any kind of food causing acute burning sensations in our belly.

Let's divide the term “acidity” into 3 categories:

  1. For coffee experts, acidity means a dry, bright feeling that tells the difference between high-grade sorts of coffee grown in the uplands and plain coffee cultivated in the lowlands.

  2. In a technical sense, acidity is a substance which can be subjected to measuring. The standard measurement for acidity is pH - 7.0 points for a substance with normal acidity and under 7.0 points –already indicates a high acidity level.

  3. For people suffering from stomachache, acidity is a killer which is better to avoid.

In order to achieve a low acid coffee, coffee beans are roasted to the darkest level possible. But the roasting kills both acidity and any other pleasant flavors which compose coffee.

coffee and stethoscopeCoffee and Blood Pressure

Caffeine (especially in coffee) is a powerful stimulant which may raise blood pressure. So how it works? It is believed that caffeine blocks adenosine which is a hormone stimulating brain cells to widen the arteries and provide right vascular supply. So taking into consideration that caffeine impedes its work, the blood vessels shrink under its influence which leads to high blood pressure. But recent studies have proven that its effect, be it negative or positive, is short-term and is unable to affect people's health.

However, in order to protect oneself from any harm, it is advised for those with high blood pressure to avoid drinking coffee with caffeine or at least lessen its daily amount to no more than 200 mg a day (1-2 cups). It could be a true savior for those people who suffer from low blood pressure. In some cases when in a critical condition, coffee can be taken as first aid.

Is Coffee a Diuretic?

You can be sure – it's a powerful diuretic when taken in large quantities. But water is a mighty diuretic as well, if taken for more than 2 liters a day. So is coffee a diuretic or not?

It was believed that coffee can really cause frequent feeling of urination but as it turned out, caffeine only acts as a diuretic when consumed in large quantity by a person who doesn't have a tolerance to it. But if you are a regular user and used to consume several cups a day, you don't have to worry about that. Your organism develops a tolerance to caffeine influence with time and doesn't react at such properties.
