According to a research at the Yokohama City University School of Medicine in Japan, the coffee is making the food go out of our stomach more quickly. This means that the minerals and vitamins are not absorbed properly, which may cause a deficiency in nutrients. This is also the case with decaf.
However, the caffeine is also playing a role. It is fastening the process of removing the liquids out of our organism through the kidneys which means that calcium, zinc, magnesium or other minerals don’t get absorbed as well.
The problems are with the magnesium because not many people are getting the proper amount of it, while it deficiency may cause many issues such as depression, asthma, anxiety, heart disease, high blood pressure, chronic pain, migraines, kidney disease etc.
Anxiety and Depression
The people who want coffee as a first thing in the morning actually want the caffeine. However, this increases anxiety and depression because of the following:
-The coffee can increase the level of the stress hormones.
-It affects the production of serotonin, which is a neurotransmitter connected with the senses of well being and calm. The antidepressants given to people are actually keeping the proper level of serotonin.
-It also affects the level of gamma-aminobutyric acid (GABA), which is connected with a lower level of stress.
-It fastens the secretion of B vitamins and then affects its absorption. The B vitamins are beneficial for relaxation, mood regulation, and management of stress.
That is why, it is best to avoid drinking your coffee on an empty stomach, especially if you are prone to some stomach issues.
