Coffee is a complex brew. It contains many compounds, some harmful some helpful. It is consumed by millions of people and some even claim they can’t wake up without a cup. I am one of those, i have to drink a cup every morning but no more than that unless i have something extremely important to do. I am doing all that research on this website, trying to find answers to different questions based on the latest studies, while drinking coffee, and i never did any research on coffee, the thing i am consuming every day. Is it bad? Good? Neither?
Coffee is made out of coffee beans that are roasted and brewed in different way depending on the type of coffee. Those beans are the seeds of berries from the Coffea plant. There are many variant of this bean coming from slightly different Coffea plants. Each is prepared in a different way and has a different flavour. Coffee always contains caffeine, unless you get decaffeinated coffee which is not really coffee. Some types do not have any essential nutrient in significant amounts (although they may have compounds that are functional – have a positive or negative effect on you other than nutrition). Espresso though has significant amounts of magnesium, the B vitamins, niacin and riboflavin.
How it works.
Caffeine is an adenosine antagonist and contains inhibitors of monoamine oxidase. This is what makes coffee a stimulant (wakes you up) and makes you happier. The way you metabolize it depends on many factors you can read more about on my sources at the end of this article.
Consuming coffee in general does not affect your risk to develop cardiovascular disease significantly. If you drink one cup a day then you may even have a reduced risk of developing a cardiovascular disease or hypertension. On the other hand if you consume more than 3 cups a day you may increase your chances of developing cardiovascular disease and this may lead to problems especially if you have any other health problems.
Type 2 diabetes.
Here i didn’t find a lot of evidence but apparently coffee doesn’t hurt diabetics. It can even be helpful. On the other hand keep in mind that many people add sugar or milk in their coffee, so this may lead to increased risk. But coffee alone seems to be fine.
While consumption of soft drinks may increase the risk of depression, coffee helps. It can have neuroprotective, antioxidant, anti inflammatory and psychostimulant effects. By affecting serotonin degradation and preserving neuron health it can help treat depressive symptoms and even help with neurodegenerative diseases although we still need to do further studies to find out whether dementia can be helped by coffee.
For those who drink a cup every day or less there should be neither an increase nor an increase in their susceptibility to cancer. Those who drink more than two cups though may have an increased risk of developing certain types of cancers.
Coffee can be bad for anxiety, insomnia, headaches, tremulousness, and palpitations. But at the same time drinking normal amounts based on how much you can handle and your bodyweight and metabolism combined with a healthy diet will probably solve those issues.
I don’t know how i could live without coffee, i would probably eventually find a way to wake up without it, but right now i am addicted. And you have to be careful because at some point you may become resistant to the effects of coffee and ask for more. When that happens i try to drink less for a while. I tend to drink one cup a day and sometimes none. When i need to work really hard then i might drink two. This way i can really feel the effects when i need them. I understand for some it may be hard to do but try to avoid coffee in the weekends or on vacation if you feel like you start to need more than one cup a day you can try that.
