What happens to your body after you drink a cup of coffee

Coffee and its relation to blood pressure

Several studies have proven that coffee consumption in moderation doesn’t have a significant effect on blood pressure. One study that lasted for over a decade, showed that zero intake and very high intake of coffee had a smaller effect on resting blood pressure levels in comparison to those who drank moderately up to 4 cups a day.

An inversely proportional relation was discovered between coffee consumption and the likelihood of developing hypertension in participants. The scientists made a conclusion that those experiencing high blood pressure symptoms should avoid caffeine, whereas those with normal levels can safely drink in moderation.

In another study that was done on adult subjects older than 60, were given 4 or more caffeinated drinks per day. The results showed that they had less than half the chances of dying of some kind of heart disease in comparison to those who drank a smaller amount. Now, that’s strange. What’s actually going on? Scientists believe that older adults usually have low blood pressure, which can drastically increase the chances of getting a heart attack. By rapidly increasing blood pressure, caffeine has a role of protecting against unpredictable heart attacks.

An interesting thing to note is that the oils found in coffee are very powerful regulators of cholesterol levels and blood pressure. When coffee beans are stepped, as it’s done in a French press, the oils are kept in the liquid and can increase cholesterol levels and the risk of developing high blood pressure. Coffee brewed by using filters traps the oils and eliminates them from the liquid.

Coffee and its relation to heart diseases

One study found that women post their menopause that drank one to four cups of coffee per day had 25% less risk of developing a heart disease in comparison to those who didn’t drink coffee. The reasoning behind this is that the antioxidants found in coffee are offering protection against the damage occurring in the cells found in the arteries’ wall, caused by aging and the outside environment.

The same as a diet that is rich in vegetables and fruits, a diet that contains a moderate quantity of coffee has been shown to reduce one of the main factors contributing to developing a heart disease, which is inflammation. This factor appears to be unrelated to the presence of caffeine in coffee, so decaf coffee would basically have the exact same benefits.

Coffee and its relation to diabetes

Several studies have tried to examine caffeine’s relation to diabetes. We already know that caffeine in its pure form can increase the symptoms of diabetes. The studies have proven that those who drink more than 6 cups of coffee per day have a significantly lower risk in the range of 60-80 % in developing diabetes type II, in comparison to non-drinkers.

Another study that was done on around 120,000  healthy participants concluded that those who drank a minimum of 5 cups per day had 30% less risk of developing diabetes in comparison to those who didn’t drink coffee. Again in this instance, caffeine wasn’t the protective factor, those drinking decaf coffee experienced a much more powerful protective effect. The reasoning behind this is that the antioxidants found in coffee have a protective role in regards to the beta-cells in the pancreas in charge of producing insulin.

Coffee’s effects on the liver

If you are an alcohol aficionado and enjoy drinking it, there is a way to improve the chances of the liver staying healthy and maintain that, by drinking coffee. A study was made on adult subjects where the researchers found that those who drank more coffee than usual, like 3 or 4 cups a day, had the least risk of developing cirrhosis.

Drinkers of coffee also showed lower enzyme levels which are indicators of how much the liver was damaged. Tea, on the other hand, had no effect whatsoever.

Coffee’s effects on the brain

Because coffee is rich in antioxidants, it is very helpful when it comes to the protection of brain health. Coffee was shown to inhibit the speed of cognitive decline related to aging and gradual development of degenerative illnesses of the brain like Alzheimer’s or Parkinson’s disease. Moderate consumption of coffee of 1-3 cups a day has repeatedly been shown to be the range that provides the most benefits. The most evident effect coffee has on the brain is mood improvement as well as improvement of the overall wellbeing.
